was proposed as a proper theoretical foundation for
problem recognition. It also implied that people develop
styles as they repeatedly deal with similar problems.
Another purpose of the dissertation was to develop a
method for typifying consumers in the way they recognize
problems. Scales were constructed to measure consumers'
tendencies to recognize problems due to a change in one of
their states. Three scales were developed: one to measure
types sensitive to changes in the desired state, one to
measure types sensitive to changes in the actual state,
and a combined scale to measure tendencies to recognize
problems due to changes in either state.
The product category chosen to test the scales was
clothing. The results indicated that all scales were
extremely reliable and moderately valid.
A major conclusion was that the theoretical findings
will have greater practical value once the link between
styles of problem recognition and types of information
search is clarified.

CHAPTER I
INTRODUCTION
This first chapter of the study briefly reviews the
general background and justification for the research.
Further, the p u r p o s e of the study as well as its
limitations will be discussed.
Background
It has been hypothesized that consumer decision
making is not so much a single act as it is a process
(Engel, Kollat, and Blackwell 1968). Though some have
posed serious questions to the basic assumptions upon
which process theories are founded (Graham 1981 , Olshavsky
and Granbois 1 979 ), it appears that the weight of the
literature still rests on process theories. One of the
foremost process theories was presented by Engel, Kollat
and Blackwell (1968). A schematic representation of their
theory is made in Figure 1. (Their theory is hereafter
referred to as the EKB model).
The main portion of the EKB model is the purchase
decision process and it is composed of the following five
stages: Problem Recognition, I n f o r m a t i o n S e a r c h ,
Alternative Evaluation, Purchase Choice, and Post-purchase

Outcomes. It is this part of the overall model that is
most widely accepted and used by a majority of consumer
behavior texts (Assael 1981; Berkman and Gilson 1981;
Block and Roering 1979; Cohen 1981; Engel and Blackwell
1982; Hawkins, Best, and Coney 1983 ; Loudon and Delia
Bitta 1 979 ). Much research has been conducted on the
steps in the purchase decision process as noted by the
attention devoted to them in the consumer b e h a v i o r
textbooks cited above. The notable exception is the
Problem Recogniton step (hereafter referred to as PR).
The chapters or sections on the other stages are usually
lengthy and well documented, with c o n c e p t s having
considerable empirical foundation. However, description of
PR tends to be brief, with few references, and with little
discussion of relevant measures or research.
The reason for the investigatory neglect of PR is not
clear. Possibly, understanding how problems occur has not
been viewed as important as the mere realization that
problems exist and that products can be marketed to solve
the problems. Traditionally, marketing's g r e a t e s t
opportunity for understanding and influencing the consumer
has come from research which focused on one of the later
stages in the purchase decision process. However, it has
been maintained by some that the marketing strategist
would benefit from an indepth understanding of the PR
p r o c e s s ( B l o c k and R o e r i n g 1 9 7 9 , p p . 3 8 4 , 3 8 5 ) . F o r

( E n g e l , K o l l a t , and Blackwel l 1968, p p . 360 , 361 ) , PR h a s

Since the components of PR have been no more than
hypothetical constructs one purpose of the research was to
empirically verify that the desired state and the actual
state do indeed exist. It was hypothesized that consumers
develop styles of PR to deal with situations which
repeatedly occur. Scales were developed to measure
consumers' tendencies to recognize problems because of a
change in either their actual states (hereafter referred
to as Actual State types) or their d e s i r e d states
(hereafter referred to as Desired State types). Depth
interviews and a mail survey were used to develop these
scales.
A further purpose of the study was to explain PR.
Previously, the literature offered no reasoning behind the
description of the process. Therefore, a search was made
in this study for a well accepted theory which could
explain and lend support to the currently a c c e p t e d
definition of PR.
It should be stressed that this research was not
attempting to refute, challenge, nor in any way modify the
EKB model. What little contradictory evidence was found
in the course of the work was acknowledged and dealt with
in discussion of the results. But, the primary function
of this dissertation was to explain and measure what has
already been described by others.
One problem with this a p p r o a c h is that o t h e r
explanations using very different constructs may very well
exist to interpret what is described in this study as the
PR process. Indeed, many other concepts and theories may
exist which are worth testing. For example, Nicosia
(1966) developed one of the first process models of
consumer decision making. It featured the interaction
between the firm and the consumer and assumed the latter
has no prior attitude toward the product. Howard and
Sheth ( 1969) proposed a comprehensive model which is best
suited to explain the brand choice process. However,
neither of these approaches described to any extent the
process of consumers recognizing problems. The PR process
was assumed so that elaboration focused on the process of
solving problems. It is only Engel, Kollat, and Blackwell
who in each of the four editions of their text ( 1 968 ,
1973, 1978, 1982) have devoted considerable attention to
PR. Although the PR process is not incompatible with the
o t h e r two m o d e l s it is only the EKB m o d e l t h a t
incorporates it as an integral part of the theory.
A limitation imposed on this research by choice was
that the variability of search activity between the
different PR types was not analyzed. Although it was
expected that Desired State types and Actual State types
differ in the amount and nature of their search for
product information this study only laid a foundation for
such a hypothesis to be tested in future work. Indeed, in
a more general sense, that was a limitation of the whole
study. Few results have been produced for the immediate
use of the marketing practioner. The implications are most
likely to assist at the theoretical and methodological
levels initially. Only after the scales developed in this
study are used in conjunction with other investigations of
consumer behavior (such as media habits, p a t r o n a g e
motives, and decision making styles) will the implications
be clear for the businessperson.
There were several limitations associated with the
study's pretest. For one thing, it was not certain at the
outset just e x a c t l y what q u e s t i o n s to ask in the
interviews in order to efficiently and effectively assess
PR style. However, being the first known effort to
investigate this construct necessitated that the matter be
resolved through professional judgment. Experience with
the interviews brought about more skillful phrasing of
questions as the pretest was conducted.
Another constraint on the pretest was its sample
being selected more on convenience than at random. This
was not necessarily a problem since pretest samples do not
have to be perfectly representative of the population
though they should include p e r s o n s from i m p o r t a n t
subgroups (Brown 1980, p. 105). Further, since results of
the pretest were not to be used to make inferences about
the population the need for a random sample was not as
critical.
A limitation shared by the pretest and the survey was
that the samples were totally composed of women. It is
8
possible that the results achieved in this research are
different than what could be expected if only men were
used. H o w e v e r , b e c a u s e PR p r o c e s s e s for f a s h i o n
consumption may vary greatly between men and women, a
limited situation was focused on in this preliminary
study. Then, with reliable and valid scales developed,
they can be tested further to note any differences that
are attributable to gender.
Another feature of both the pretest and the main
survey that could be viewed as a problem is that the data
was derived exclusively from self-reported measures. It
is possible that such data differ from what could be
learned if actual behavior was observed. To be of any
value, however, observation would have to take place for
several weeks or months in order to determine adequately
the tendency one has to recognize problems a certain way.
Such intense and extended observation was not practical in
this nor much of any marketing research.
A mail panel was originally planned for use in the
main survey as the means for collecting data. When a
panel could not be secured a mail survey was conducted.
Low response rate and response bias were acknowledged
weaknesses of the approach. However, these were not
viewed as significant problems since the results of the
survey were not intended to be inferential in nature.
Therefore, scale construction with its attendant focus on
internal validity was emphasized over external validity.
Two important questions which were not addressed by
this study are how do people's PR styles vary over time
and how are they affected by product category involved.
It was expected in both cases that PR styles do change;
i.e., the predominate way in which one recognizes problems
within a particular product category can change over the
years as other factors in one's life change; and, the way
one recognizes problems differs depending upon the product
category involved. Both hypotheses are worth testing but
require that proven scales for measuring PR be available.
That was the purpose of this research.
Finally, a related point that was also not addressed
in this study concerns the determination of how dynamic PR
styles are within product categories. It was assumed that
a consumer's PR style varies from category to category yet
is basically stable within a product category. However,
such a hypothesis is yet to be tested. Certainly, it
would seem that the more similar two products are in the
need they satisfy then the more similar the manner of PR.
The converse would also seem to be a safe assumption.
But, where the boundaries are of a product category cannot
be determined accurately without further investigation.

Organization of the Study
The next chapter reviews literature relevant to the
description and explanation of PR. It also looks at
previous attempts to measure PR and suggests a new
approach. The third chapter discusses the methodological
issues involved with the study's pretest and main survey.
Chapter four presents the findings and the last chapter
discusses conclusions of the study.

CHAPTER II
REVIEW OF THE LITERATURE
The EKB model was the first popular application of
the five-stage decision process to consumption behavior.
Almost identical conceptualizations were already well
known in the area of general decision making (e.g., Brim
et al 1962). With reference to PR in particular, there is
tremendous similarity between the Engel, Kollat, and
Blackwell (1968) definition and those of several decades
earlier. The definition they gave was that "problem
recognition r e s u l t s when a c o n s u m e r r e c o g n i z e s a
difference of sufficient magnitude between what is
perceived as the desired state of affairs and what is
perceived as the actual state of affairs" (pp. 360 , 361 ).
This is quite similar to a statement made by psychologist
Karl Duncker: "A problem arises when a living creature
has a goal but does not know how this goal is to be
reached. Whenever one cannot go from the given situation
to the desired situation simply by action, then there has
to be recourse to thinking" (1945, p. 1).
Dewey (1910) described the initial step of problem
solving as "the conflict between conditions at hand and a
desired and intended result, between an end and the means
12
13
for reaching it" (p. 72). The relevance of PR to a proper
understanding of the decision process was obvious to Dewey
for as he has pointed out, "the problem fixes the end of
thought and the end controls the process of thinking" (p.
12) .
These descriptions bear s i m i l a r i t y to several
different theories which could be used to explain the
operation of PR as it is now defined in the literature.
What is alike in each of these approaches is that humans
are viewed as tending to m a i n t a i n some l e v e l of
activation. As Maddi (1976) explains, "There is a general
tendency in psychology for all tension reduction theories
to be considered homeostatic in nature. T h u s , the
theories of Freud, Sullivan, Angyal, Bakan, Rank, Kelly,
and Festinger, if not a few others as well, would be
considered homeostatic positions" (pp. 169, 170).
Homeostasis does sound very much like PR for as one
writer put it, "homeostatic activities have as their goal
the reduction of a discrepanacy between a preferred state
and the actual state" (Stagner 1974, p. 97). Therefore,
due to its conceptual simplicity, its acceptance and use
in other fields of study, and the ease with which it can
be applied to consumer behavior the homestasis concept was
used in this research to explain PR. The next sections of
this chapter will focus on the origin of homeostasis and
14
its description as well as its use as an explanatory tool
in the understanding of PR.
Homeostasis
The percept and even the concept that some sort of
natural balance tendency operates in the body has been
discussed for over 200 years (Cofer and Appley 1964,
Langley 1973). However, it was not until 1926 that the
term "homeostasis" was coined for the process by W. B.
Cannon. Although the process is still not completely
understood, homeostasis is an undisputed principle in
physiology prompting one writer to remark that "without an
appreciation of homeostasis and the comprehension of
homeostatic mechanisms, medicine is e m p i r i c a l , not
rational" (Langley 1973, p. 1). Homeostasis is defined in
Dorland's Illustrated Medical Dictionary thusly: "A
tendency to stability in the normal body states ( internal
environment) of the organism. It is achived by a system of
control mechanisms activated by negative feedback" (1974,
p. 720).
A good illustration of the concept as applied at the
physiological level involves the body's regulation of
temperature.
The body temperature tends to remain steady at about 37° C (98.6°). This is not an exact figure, however, and we must think of an upper and lower threshold value, variation being t o l e r a t e d w i t h i n l i m i t s . So, a r i s e in
15
temperature to 37.1° may have no perceptible effect. However, a rise to 38° is likely to set off corrective actions: sweating, relaxation of skin blood vessels, reduced metabolic activity, and so on. These generally lead to restoration of the t e m p e r a t u r e w i t h i n normal l i m i t s . Conversely, if the figure falls to 36° , the skin will pale as blood vessel constriction occurs, shivering may cause heat production through muscle contraction, etc. (Stagner 1974, p. 21).
It should be understood from an example such as this
that temperature is not restored by homeostasis but is
merely an example of homeostasis. Further, it is not that
an absolute difference between actual temperature and
proper temperature triggers corrective action but that a
difference of sufficient magnitude occurs.
One of the first major efforts to explore the topic
of homeostasis was The Wisdom of the Body by Cannon
(1932). He described the tendency of the body to maintain
equilibrium in an effort to preserve its existence in the
face of numerous environmental obstacles. Chief among the
ideas presented by Cannon is the notion of " s t e a d y
states." These represent conditions which the body seeks
to maintain.
Even though the focus of this early book was on
homeostasis in its physiological sense an epilogue was
provided to explore another application. Cannon appears to
be the first to make the leap from the biological realm
and suggest some of the implications the concept might
have for human society at large. These thoughts, however,

replenish their supplies of sugar and other necessary chemicals is infinite. Men beg, borrow or steal; they work for wages or they may refuse to work; but the normal outcome of any human activity is to restore some disturbed balance, physical or chemical, in the human organism (p. 7).
One of the first to t h o r o u g h l y i n v e s t i g a t e
homeostasis in its psychological application was Freeman
(1948). He stated quite flatly at the beginning of his
book "that all behavior is an a t t e m p t to p r e s e r v e
organismic integrity by ' homeostatic 1 restorations of
equilibrim" (p. 1). Freeman based this thesis of his on
objective analysis of psycho-physiological research and
rejected the psychic energy constructs of Freudian theory.
Freeman's work still stands as one of the few well
developed theories of homeostasis. Among the series of
"homeostatic principles" he set forth, one is particularly
notable since it was later modified and enriched to meet
some of the criticisms leveled against the theory. This
is the idea of "adjustment levels." As Freeman explained:
The organ or cell is the primary immunological level of defense. A higher and more complicated level is found in the generalized emergency reactions of the total organism, integrated via the autonomic nervous system. The highest level involves cerebrally controlled total behavior, including response that is specifically adaptive to external stimulation and the so-called "ego defenses" that guard the inviolancy of the personality from psychological insult (1948, p. 98) .

homeostasis," past interactive experience with the
environment can modify one's behavior. Thus, through
experience a person learns to listen to weather forecasts
and dress accordingly. Therefore, anticipation of a
potential disturbance of a steady state can motivate one
to take steps to m i n i m i z e such an u n c o m f o r t a b l e
possibility.
Another important concept described early on by
Stagner (1951) also related to Freeman's "levels of
adjustments," dealt with the phenomenon of nonhomeostatic
behavior. Responding to the observation that some human
activities seem to upset equilibrium (e.g., hazardous
hobbies and sports, gambling, delayed gratification,
working to exhaustion), Stagner (and Karwoski 1952)
offered the "principle of dominance." It states that the
organism often has conflicting needs and behavior is the
result of the more dominant needs being satisfied before
other less potent needs. This process has been termed
"heterostasis" by Davis ( 1 958 ). Though some of this was
stated in Stagner's first article on homeostasis in 1951
it was not until later writings that all the concepts and
terms were fully integrated. The conception was made
complete with the addition of "the hierarchy of steady
states."
Each person has a hierarchy of steady states, those uppermost in the hierarchy being dominant

21
Related to this and other thoughts of Stagner's are
some comments made by Mace ( 1953) in his presidential
address to the British Psychological Society. He argued
that a properly modified understanding of homeostasis
offered a basis for a psychology of values. T h r e e
extensions of the homeostatic concept were proposed:
The first extension would cover the case in which what is maintained or restored is not so much an internal state of the organism as some relation of the organism to its environment (p. 204) .
The second extension would cover the case in which the goal, and/or norm is some state or relation which has never p r e v i o u s l y been experienced (p. 205).
The third way in which the concept can be extended is that in which it would cover second and higher order needs . . . it is the state in which the greatest satisfaction would be given to the total system of original and acquired needs (p. 206).
Mace's first extension indicates that the adjustment and
adaptation of humans to their environment is a homeostatic
process. Secondly, he proposes that maturation and
learning are also homeostatic in nature. Finally, in his
third e x t e n s i o n Mace infers that h o m e o s t a s i s is
fundamental to the development of a system of values and
personality. By broadening homeostasis thusly Mace has
proposed that the concept be the foundation for all
motivation. Further, as has been noted by others (Cofer
and Appley 1964, p. 326), Mace would see problem solving
as an instance of tension reduction. This gives added
22
credence to the conception of consumer decision making as
a homeostatic process, as is discussed in the following
section.
Use of Homeostatic Concepts in Understanding Problem Recognition
There is little difficulty encountered in applying
homeostasis to the consumption process. Given that
homeostatic principles are understood to pervade much
human behavior, its application in consumer behavior
should not be surprising. However, the only apparent use
at the present time is merely noting its function in the
general motivation context (Cohen 1981, 201; Howard and
Sheth 1969, p. 101; Loudon and Delia Bitta 1 979 , p. 305 ).
As it is described below, the application could be much
greater.
One of the major contributions of homeostasis to
consumer decision making is the notion that there is some
kind of "steady state" for every need the consumer tries
to satisfy. "Steady state," then, relates to the desired
state in PR terminology. Because the existing conditions
in which consumers find themselves vary over time the
situation called the actual state is also an essential
ingredient for a complete model of the c o n s u m p t i o n
process. In the context of consumption, homeostasis is
seen to be the tendency for an individual to be motivated
23
to search for products that are perceived to help decrease
the difference in the actual state and some desired state,
therefore, leading to the accomplishment of the "steady
state."
Another contribution of homeostatic theory has to do
with the immediacy of PR once an imbalance has occured.
As was mentioned above in the body temperature example,
energy mobilization for regaining the proper condition
does not necessarily begin just as soon as the actual
temperature is different than 98.6° . There appear to be
threshold levels operating which must be breached before
restitutive behavior is initiated. Such is the case with
PR. It is not a condition of difference itself between a
particular desired state and actual state which is
important, but the degree of difference necessary to draw
attention to the matter.
Finally, another implication for PR from homeostasis
is that the process can occur both due to a change in the
desired state as well the actual state. This would not be
a logical indication if homeostasis was only observed in
its physiological setting. In situations such as in a
closed system, energy activation occurs when the existing
condition departs sufficiently from its permanent "steady
state." In other words, the desired state never changes
and if a problem exists it is due to a change in the
24
actual state. Even in consumer behavior some would
maintain that PR occurs most often because of a change in
the actual state, e.g., running out of a product which had
previously solved the problem (Engel, Blackwell, and
Kollat 1978, p. 229). However, in an open system, movement
can come in either of the states and thereby set off PR.
That the desired state itself can change is evidenced in
"dynamic homeostasis" and behavior involving positive
valences, discussed above.
Drawing from the foregoing discussion it can be
assumed that many of the concepts from homeostatic theory
are isomorphic with ideas developed to describe the PR
stage in the consumer purchase decision process. With the
similarity between the two processes, the empirical
strength behind homeostatic theory lends support to the
hypothesis that much of the current conceptualization of
PR is indeed correct. For purposes of this study, Figure
2 is adopted as a satisfactory illustration of the PR
process. The next step is to determine a means for
measuring the constructs which should exist if this
portion of the consumer decision process model is valid.

construct. For example, there is the purchase probability
scale discussed by Granbois and Summers ( 1972). Although
it was not conceptualized as such, the measure may be
interpreted as estimating the degree of discrepancy
between the actual state and the desired state. However,
it does not determine how the gap occured. The Problem
Inventory Analysis (Tauber 1975) determines for a list of
problems what products, brands or activities consumers
associate with each. Two additional measures are suggested
by Hawkins, Best, and Coney (1983), activity analysis and
product analysis. In general, they are designed for
exploring what problems exist with particular products and
activities. Thus, the procedures used in previous research
dealing with PR measure only the existence and degree of
problems.
If PR is indeed a homeostatic process then another
approach to measurement is available. That is, because of
the extensions made by Mace ( 1953 ) to the application of
homeostasis in psychology, referred to earlier, it can be
inferred that consumers are likely to develop PR styles as
they repeatedly deal with similar consumption problems.
What is lacking then are scales to measure whether one is
an Actual State type or a Desired State type. The benefit
of having such scales is that it will enable researchers
to determine if, for example, a different search activity
27
is engaged in by different PR types. If a significant
difference is found, preparation of separate marketing
mixes for the different groups may be justified.
This should be of interest to the marketer because
one outcome of PR is no search activity and, therefore, no
purchase (Block and Roering 1979, p. 370, 371). The
marketer should be concerned with assisting the consumer
to take the other option, to search for information to
solve the problem. The hypothesis is that the marketer can
develop strategies for specific consumer groups based on
their respective types of PR. These strategies would be
designed to ease consumers into search activity and to
provide them with the information and influence most
likely to appeal specifically to them. Such strategies
are contrasted against treating all consumers alike in
reference to PR, not realizing that why one person is
shopping for a product may be very different than the
reason behind another person's search for the same
product.
In the next chapter development of PR scales will be
discussed. Further, the methodology of scale testing will
be specified.

CHAPTER III
METHODOLOGY
This chapter will discuss those issues involved in the
testing of hypotheses concerning the composition and
measurement of PR. The first section below concerns the
development of the scale items tested in this research.
The following section deals with the preliminary work to
ascertain the adequacy of the scale items before they were
employed in the main survey. The final section discusses
the survey sample and instrument as well as the techniques
used to determine the validity and reliability of the
scales developed for measurement of PR.
Scale Development
Any attempt to measure the PR construct through some
sort of test scale must deal with the issue of specificity.
There can be several levels of abstraction leading to the
measurement of different, though related, constructs. For
example, PR could be measured for a specific purchase
decision, it could be measured as it relates to purchases
within a single product category, or it could be measured
as a trait with similar effect on all purchase decisions.
The middle ground was selected for study here. This
approach was chosen based on the assumption that PR for any
30
31
particular purchase decision is too specific to be of help
in predicting its working in any other particular purchase
decisions. Also, while it is possible that consumers could
be characterized by most purchase decisions tending to be
triggered by a significant change in just one of their
perceived states, it is also quite likely that differences
exist across product categories. Although he does not
mention PR per se, Howard ( 1977) seems to suggest such an
approach when he says, "Arousal is a general effect,
specific not to any brand but only to a product class" (p.
136). Therefore, in this initial exploratory work the
focus was on the measurement of the PR construct as it
related to a single product category.
A second area of concern was the manner in which the
measurement was to be made. To be flexible enough for use
in both personal interviews as well as in the mail survey,
the se1f-designating paper-and-pencil approach was
selected. Likert-type statements were used which focused
on the manner in which purchase decisions tended to be
initiated. The following were assumed to be the major
determinants of the desired state (Engel, Blackwell, and
Kollat 1978): (1) the influence of other decisions; (2)
reference group influence; (3) the desire for novelty; (4)
the effect of marketing efforts; and (5) motive activation.
Likewise, the following were accepted as the m a j o r
influences on the actual state: (1) depletion of the
32
previous solution; (2) dissatisfaction with the previous
solution; (3) altered circumstances; and (4) marketing
efforts. Graphical representation of these determinants
was made earlier in Figure 2.
The specific product category chosen for investigation
in this study was wearing apparel. It was considered to be
appropriate for study since a priori types are easily
recognized; i.e., there are those who buy clothes because
of their sensitivity to fashion changes, and there are
others who are not motivated to purchase until what they
have wears o u t . This is not true of all p r o d u c t
categories. Some are characterized by PR occurring for
consumers mainly because their actual states have changed,
e.g., gasoline. Conversely, those who buy products such as
recorded music do so most likely because changes have
occured just in their desired states. However, with
clothing, both PR styles appear to be evident and neither
seems to dominate. Therefore, statements were needed
specific to the clothing need which reflected either a
change in a desired state or a change in an actual state.
Positive statements for each of two scales, one for
the actual state and one for the desired state, were
relatively easy to generate based on the hypothesized
determinants discussed above. Development of negative
statements was more difficult. This was because negative
33
statements for one of the scales could be interpreted as
positive statements on the other scale. Although one
possible solution was to not use negative items in scale
development, this was rejected since equal use of positive
and negative statements is recommended (Nunnally 1978/ p.
605). The choice here, therefore, was to generate both
positive and n e g a t i v e items w i t h o u t linking them
specifically to either of the two scales. A total of forty
statements were developed and are presented in Table 7 of
the Appendix.
A graphic rating scale was placed next to each
statement on the questionnaire. The rating scales were
also numerical scales since numbers were used as anchors.
A number could be circled by a subject to indicate response
to an item. Seven steps were offered on the scale. This
level of steps was selected because it has been noted that
the reliability of individual rating scales increases with
the number of steps employed and this increase tends to
level off at about seven steps (Nunnally 1978, p. 595). The
steps on the scales were defined at the top of the
questionnaire form. The verbal anchors reflected degrees of
agreement and disagreement. When completing the form
respondents were expected to indicate their sentiments by
agreeing or disagreeing with favorable or unfavorable
statements.
34
Pretest
The data gathered in the pretest were intended to aid
the researcher in selecting statements to be used in the
survey stage of the study. More specifically, as a
foundation for the success of the survey, statements were
required which could distinguish between the responses of
an Actual State type and those of a Desired State type.
Although in a more powerful sense, this is what was done
eventually in the factor analysis of the survey data.
However, if pretesting of the items was not done the
inadequacy of particular items would be learned only after
the data were collected. By pretesting, the likelihood of
having effective discriminators in the survey was
maximized.
Sample Design
To obtain a pretest sample, a list of 200 names was
randomly selected from the Denton telephone directory.
The sample was selected from Denton because it was felt
that people living in the community would be most willing
to cooperate given the importance of the university to the
area. Further, the time and financial constraints did not
allow for personal interviews to take place too far afield
since the researcher's office and interviewee's home were
the two principal sites for interviews.

Data Collection
The pretest basically involved two m e t h o d s of
collecting data: questionnaires and interviews. As just
discussed, the questionnaire was mailed to the subjects.
They were asked to fill out the form and bring it with them
to the interview. This was done to prepare them for the
interview, to help motivate them to come to the interview,
and to m i n i m i z e the time r e q u i r e d of them at the
interview.
The questionnaire included several sections. The main
part was composed of the forty positive and negative PR
statements discussed previously. It should be noted that
although the items were written to be general enough to
study fashion as a broad product category the subjects were
asked to think about sportswear, in particular, when
responding. Sportswear was defined on the questionnaire as
including blazers, jeans, pants, shorts, skirts, tops, and
vests. This was done in an effort to have as m u c h
continuity of thought among the subjects as possible.
Anytime a scale is developed a concern is whether
respondents are expressing their true sentiments or
are merely answering in a way they feel is socially
desirable. The Marlowe-Crowne Social Desirability Scale
(Crowne and Marlowe 1960, 1964) was constructed to help
answer this question and it has become an accepted part of
scale development in psychology. It was included in the
37
questionnaire to note if the PR scales measured anything
besides the respondent's desire to answer in a socially
approved manner. High correlations (greater than ±.7)
between the Social Desirability Scale and the PR scales
were hypothesized to indicate that responses to the latter
are influenced by non-test-relevant factors, thereby
limiting their usefulness.
The questionnaire also collected socioeconomic and
demographic information. The variables of this sort
studied were the normal ones such as occupation, income,
education, age, sex, and marital status. This information
was not of primary concern in the study but was collected
not only to describe the sample but to be available for any
auxilary investigations that may be undertaken.
The second part of the pretest was the interview and
it began when the subject and the researcher met at the
designated time and place. Kahn and Cannell (1957, pp. 80,
81) have stated that it is important for interviewees to
clearly understand at least three things: the purpose of
the interview, the use to be made of the i n t e r v i e w
information, and what is expected of them during the
interview. Individuals were told the purpose of the
interviews was to better understand what basic reasons
eventually lead to people buying clothes. They were also
informsd that the information gathered would help specify
38
the types of consumers that exist. Respondents were told
that they were expected to be honest and open in their
statements but to speak up if they needed clarification or
felt a question was too personal. In addition to these
points, the subjects were told that the interview should
not take more than thirty minutes. Finally, it was
explained that the interview sessions were recorded so that
a clear though temporary account of what was said could
assist the researcher in understanding an individual's
purchase behavior.
The interview itself amounted to the researcher asking
a series of six questions. The following are those six
questions and the sort of responses expected from the two
PR types:
1. "Describe your wardrobe to me, especially its size and
the kind of clothes that are in it." It was expected
that Actual State types would emphasize the lack of
large wardrobes yet the adequacy of what they had for
their purposes. Contrawise, Desired State types were
were anticipated to speak of large wardrobes although
they might mention that many of the clothes were not
worn much since they were out of style.
2. "Tell me about your interest in and your time spent
clothes shopping." D e s i r e d State types were
hypothesized to talk of spending more time and having
39
greater interest in shopping than Actual State types.
Further, the latter persons were expected to emphasize
their lack of interest in the activity.
3. "How important to you is fashion and dressing in
style?" Answers by Desired State types were expected
to reflect a great interest in having stylish clothes.
Actual State types were anticipated to show a lack of
interest although they might indicate some sensitivity
to wearing items very much out of date.
4. "Tell me about the amount of money you spent on clothes
in the last few years." This question was anticipated
to indicate the greater amount of money spent by the
Desired State types and their regularity in doing so.
Actual State types were expected to express more
v a r i a n c e in a m o u n t s spent and lower a v e r a g e
expenditures.
5. "How much effect on you are your friends' fashion
opinions and their ways of dressing?" Responses from
Desired State types were hypothesized to show evidence
of compliance, identification, or internalization with
peer group norms (Kelman 1961). Actual State types
were expected instead to mention that either they did
not care about what other people thought or that their
friends did not show much concern over dressing in
style.

41
Scoring and grouping of subjects was done as follows:
if an individual gave a response hypothesized as typical of
a Desired State type problem recognizer, then a score of 3
was given; if the response was one hypothesized as
characteristic of an Actual State type, it was scored as 1;
and if the response did not fit either of the extremes, it
was scored a 2. Then, each respondent's scores to the six
questions were summed. If the total was 6, 7, 8, or 9 they
were classified as Actual State types. If the total was
15, 16, 17, or 18 they were placed in the Desired State
type category. Totals between 10 and 14 inclusive were
interpreted as representing people who were "in-between"
and had characteristics of both PR types.
The bulk of the analysis work performed at this stage
of the research centered around determining if the various
scale items were effective at discriminating between the
different PR types. A nonparametric statistical measure
was selected for use in this task for a couple of reasons.
Firstly, in a strict sense, the quality of data collected
from responses to the Likert-type statements was ordinal.
It is true that in later stages of the research that the
parametric routine of factor analysis was used. However, by
that time, data was normalized and linear combinations were
produced making it more amenable to parametric procedures.
During the pretest, all that was required was some test to
42
note whether the central tendencies of the two extreme
groups on each item were significantly different.
The second reason for preferring a nonparametric test
concerned its lack of assumptions about the distribution of
the parent population. As is explained by one
statistician:
The parametric tests require a specific assump-tion concerning the underlying distribution of the data. In many cases the sample size is not sufficiently large nor are the data sufficiently close to a normal distribution to allow such an assumption. A number of statistical tests exist for dealing with such cases. These statistical procedures are referred to as nonparametric tests (Brite 1980, p. 320).
The nature of the sample used in the pretest would seem to
indicate that a nonparametric test was the most appropriate
analysis to use.
The specific nonparametric procedure selected for use
was the Mann-Whitney test. This particular test was chosen
because of the greater power it is recognized as having.
Speaking of the test's asymptotic relative efficiency
(A.R.E.) Conover (1971) has said:
. . . the A.R.E. of the Mann-Whitney test is never too bad when compared with the two-sample t-test, the usual parametric counterpart. And yet the contrary is not true; the A.R.E. of the t-test may be as small as zero, or "infinitely bad." So the Mann-Whitney test is a safer test to use (p. 224).
43
For each scale statement the null hypothesis was that the
median response of the Desired State group was not
significantly different than the median response of the
Actual State group. The level of significance used in the
tests was .10 percent.
Finally, it should be pointed out that not only was a
statistically significant difference looked for on each
item but conceptually appropriate medians were required as
well. Specifically, for each item the median of the Actual
State group of responses and the median for the Desired
State group of responses were required to fall within oppo
site ends of the scale. That is, if one group's median
fell in an area indicating agreement with a statement then
the median for the other group needed to fall in the area
indicating disagreement with the statement. When a
statement failed at being either statistically or
qualitatively different it was not used further in the
research.
Survey
The intent of the survey was to gather data which
would enable the researcher to complete the construction of
scales for measuring PR styles. The manner in which the
data was collected as well as the method of analysis had
the aim of producing scales which were both reliable and
valid.
44
Sample Design
The population studied in this research could be
defined as those female American consumers who purchase
their own clothing. The sample drawn was as representative
of the p o p u l a t i o n as p o s s i b l e g i v e n the r e s o u r c e
constraints within which the research was conducted.
The ideal sample size for use in this research was
determined with the understanding that a multinomial
population was to be sampled rather than a binomial
population. That is, three styles of PR were hypothesized
to exist in the population which required a different
sample size than if only two groups were thought to exist
(Tortora 1978, Tull and Hawkins 1980). Based on work with
similar statements (Bruner, Greenberg and Lumpkin 1982), a
rough estimation of proportions was made. Specifically,
Actual State types were expected to compose twenty-four
percent of the population, twenty-six percent were expected
to be Desired State types, and the remaining fifty percent
were anticipated to be "In-between" types. With these
expected proportions, an absolute precision of ± 5 percent,
and a confidence coefficient of .95, the minimum sample
size was computed to be 587.
One of the major concerns about the sample since
factor analysis was to be used on the data was having a
45
sufficiently large sample in relation to the number of
statements being tested. According to Nunnally, "unless
the number of subjects is at least ten times as large as
the number of items, factor analysis can take great
advantage of chance" (1978, p. 276). Because there were
just forty statements the sample size of 587 discussed
above was sufficient for the factor analysis.
It was originally planned that this study would gather
its data from a panel. Ultimately, however, the panel was
not available for use at the time required. This
necessitated the use of a mail survey. Due to time
constraints the sample was drawn from telephone books of
six communities in the Dallas-Ft. Worth metroplex each
having just one zip code. This greatly facilitated the
mail out. A total of 2000 names were drawn and
questionnaires sent to that group. Cover letters
instructed the recipients to have an adult female in the
household fill out the form. It was expected that enough
households with adult females would complete and return the
questionnaire so as to satisfy sample size requirements.
It was also accepted, however, that response bias might be
a problem. Therefore, the inferential value of the data
was considered to be limited.
Survey Instrument
As was mentioned in the previous sections the data was
collected through use of a mail questionnaire. The
46
instrument was similar to the one used in the pretest in
that it included the PR scales and the d e m o g r a p h i c
questions. The Social Desirability Scale was not utilized
again. However, the Sensation-Seeking Scale (Zuckerman et
al 1964, Zuckerman and Link 1968) was included. The scale
is well accepted in psychology as a measurement of optimal
stimulation level. It was used in this research to aid in
the establishment of construct validity, as is explained in
the next section.
Data Analysis
Scales are constructed many times based purely on the
judgment of trained researchers. However, if intuition and
experience by themselves are used to develop some measure
of PR several competing explanations would be possible:
that only one scale is required since the desired state and
the actual state are merely opposite extremes of a single
factor; that two scales are necessary since there are two
definite dimensions to PR, change in the desired state and
change in the actual state; and, that several scales are
needed to measure the multiple factors more specific than
just the desired and actual states which may trigger PR.
Rather than relying just on intuition a systematic approach
was needed which would define "which variables exhibit high
intraset correlations and low interset correlations, how
47
many sets there are (each set defining a dimension), and
whether the dimensions can be considered as uncorrelated
themselves" {Green and Tull 1978, p. 421). Such a
procedure is known as factor analysis and it was used in
this research to locate and measure the dimensions assumed
to compose PR.
In that sense then, the work was confirmatory factor
analysis because definite hypotheses were tested. And yet,
it might be better described as a "quasi-confirmatory"
study (Mulaik 1972, p. 363) since the work represents the
first known effort to empirically investigate the latent
variables of PR. In some sense, then, the research was
still quite exploratory and much development, modification,
and verification of the theory remains to be done.
The particular method of factor analysis chosen for
use in this research was image analysis. Although image
analysis has characteristics of both the major forms of
factor analysis, component factor analysis and common
factor analysis, it is more often linked with the latter
(Cattel 1978, Harman 1976, Mulaik 1972, Nunnally 1978).
The link with c o m m o n factor m o d e l s is due to the
development of image analysis {Guttman 1953, Kaiser 1963)
to deal with the traditionally thorny issue of separating
the common and unique parts of variables in a set. As
Harman (1976) explains:
48
The point of departure for image theory is the use of the multiple-correlation approach to identify "commonness." Guttman proposed this in contradistinction to the partial-correlation approach of the more traditional factor analysis, in which the new hypothetical constructs (the common factors) are partialled out to explain the correlations among the variables. Alternatively, these correlations can be explained by means of the multiple regression of each variable on the remaining n - 1 variables of the set. The squared multiple correlation (SMC) for a parti-cular variable represents the proportion of its total variance that is dependent on the remaining variables or how much it has in common with the other variables. The remainder of the unit variance represents the p r o p o r t i o n of the variance that is unique to the p a r t i c u l a r variable (p. 221.)
Therefore, the image of a variable is considered to be the
common part of the variable which can be predicted by all
the other variables in the set.
One of the main reasons for choosing image analysis
was for its ability to make psychometric inferences. That
is, inferences about a universe of psychological variables
may be drawn from a subset (though not necessarily a
representative sample) of that universe. Some other factor
analysis methods also share this ability but one of the
unique advantages of image analysis is that it can directly
compute scores of people on the factors rather than just
estimating them.
Another issue that had to be dealt with was rotating
the factors. Rotation is usually necessary to obtain a
49
more meaningful set of factor loadings and to aid in the
computation of factor scores. Little has been written to
suggest what type of rotation is best to use with image
analysis. However, one of the early writers on the
technique (Kaiser 1963) r e c o m m e n d e d an o r t h o g o n a l
rotation, one in which the r e s u l t i n g f a c t o r s are
uncorrelated. This r e c o m m e n d a t i o n along with the
difficulties of interpreting the results of oblique
rotations (Nunnally 1978, pp. 376-382), those solutions in
which factors are to some degree correlated, led this
researcher to opt for the orthogonal approach.
One particular orthogonal rotation is the Varimax
method. It was devised to satisfy Thurstone's simple
structure criteria (1947, p. 335) and has also been found
to have the property of invariance (1947, p. 361). The
former refers to general principles widely accepted for
guiding rotation so that some relatively pure variables
define each factor. The latter concept has to do with the
ability of a particular factor solution based on a sample
of tests to accurately portray the factors that could be
found in the universe of such tests. Based upon these
advantages, the Varimax method of rotation was selected for
use in this study's factor analysis.
The Statistical Package For The Social Sciences (Nie
et al 1975) was used to perform the image analysis with
50
Varimax rotation. The routine was set up to retain factors
with eigenvalues greater than 1.0, as suggested by Kaiser
( 1 963 ). It was expected that if simple structure was
achieved then factor scores would be directly computed by a
routine using data from all variables composing a factor.
However, if the factor loadings did not a d e q u a t e l y
represent simple structure then the determination of factor
scale scores would be approached differently. In such a
situation, a scale would be c o n s t r u c t e d for each
significant factor and would be composed of only those
variables that had high loadings. "High" was operationally
defined to mean that an item had a loading of at least .50
on one factor and loadings of no more than .30 on other
f a c t o r s . T h i s r u l e of t h u m b c o n f o r m e d to the
recommendations in the literature (Comrey 1973, p. 226;
Lundstrom, Dunn, and Skelly 1980, p. 452; Nunnally 1978,
p. 418).
It was expected that the data would go through several
iterations of factor analysis before a final solution was
achieved. That is, several items might not load well on
any of the major factors after the initial factor analysis.
Similar to the above rule of thumb, items that did not have
a loading of at least .50 on one of the major factors were
eliminated from the next round of factor analysis. This
process continued until a few factors remained, they
51
explained a majority of the variance, and each item
remaining loaded high on just one of these factors. Such a
procedure was anticipated to lead to a more interpretable
set of factors and a more manageable set of variables.
When developing test scales the issues of validity and
reliability must be dealt with. In this study, measurement
of internal consistency was accomplished through use of
Cronbach's Alpha coefficient (Cronbach 1951, Parameswaren
et al 1978). It is a standard procedure for measuring
reliability: in effect, the total set of items is divided
into all possible "equivalent" halves; then, the scores for
each pair of halves are correlated, with the average of the
correlations taken as a measure of internal consistency of
the instrument. Scores of less than .50 were viewed as
indicating questionnable reliability. Scales with scores
greater than .80 were viewed as having good internal
consistency.
Validity measurement is a harder task to accomplish.
At the very least a test instrument must be reliable before
it can be valid. Further, there are several types of
validity. The three tested in this study were content
validity, construct validity, and concurrent validity.
Establishing content validity has to do with conceptually
defining the universe of content of the property being
measured.
52
The researcher has to specify what the variable is and what it is not . . . . The researcher's next step is to formulate a large collection of terms that broadly represent the variables as defined. The researcher needs to be quite careful to include items from all the relevant dimensions of the variable (Churchill 1979, p. 257).
Not only were these procedures followed in the present
research, but other researchers knowledgeable in the area
were asked to judge how representative the items were of
the subject matter. Further, a moderate level of internal
consistency is an indication, though not infallible, of the
existence of content validity (Nunnally 1978, p. 93).
Construct validation was partly dealt with through use
of the factor analysis method. It has been identified by
Kerlinger (1973) as possibly the most powerful construct
validation method. He explains:
In order to study the construct validity of any measure, it is always helpful to correlate the measure with other measures . . . . But, would it not be more valuable to correlate a measure with a large number of other measurements? How better to learn about a construct than to know its correlates? Factor analysis is a refining method of doing this. It tells us, in effect, what measures measure the same thing and to what extent they measure what they measure (p. 468).
Construct validity was also studied through use of the
correlation between the results of the Sensation-Seeking
Scale and the PR scales. It was expected that the domain
53
measured by the PR scales would overlap with that measured
by the Sensation-Seeking Scale. For example, it was
expected that a person who showed a strong tendency to
purchase because of a change in the desired state was also
likely to be one who needed varied, novel, and complex
sensations. In this light then, a correlation of ± .7
between the measures was considered as evidence of the
construct validity of the PR scales.
A subcase of construct validity is nomological
validity. It was particularly relevant in this study since
it involves the relating of measures to some theoretical
model. In the previous chapter the test items were
generated based on the EKB model. In effect, a hypothesis
was developed stating that an actual state and a desired
state exist and operate to trigger PR. Since another major
purpose of factor analysis is to test hypotheses, "if the
factors emerge as predicted, the hypothesis is to this
extent confirmed, the factors would seem to have 'reality"'
(Kerlinger 1973, p. 687).
Concurrent validity is a form of predictive validity
and is "determined by, and only by, the d e g r e e of
correspondence between the two measures involved. If the
correlation is high, no other standards are necessary"
(Nunnally 1978, p. 88). One of the efforts to establish
concurrent validity used the scores assigned to the
54
subjects based on the depth interviews and their respective
scale scores. The former was the criterion and the latter
was the predictor test. The correlation between the
interview scores and the Actual State Scale scores was
computed, as was the former with Desired State Scale
scores. To the extent that the correlations were above ± .7
then concurrent validity was evidenced.
Beyond this quantitative approach to concurrent
validity, a qualitative method was employed too. This
approach amounted to making two predictions of a subject's
PR type based on the scale scores and then comparing these
two categories to each other and to the judgment made from
the interview. More specifically, for each of the scales
developed from the factor a n a l y s i s the m e d i a n was
determined for the group of scores. Those scoring above
the median on the Actual State scale were categorized as
Actual State types, and those scoring below the median were
categorized as Desired State types. A similar procedure
was used to place subjects into one of the two groups based
on their scores on the Desired State scale. The purpose
was to determine if a Desired State type did indeed score
high on the Desired State scale but low on the Actual State
scale. The opposite needed to be shown for Actual State
types.

CHAPTER IV
FINDINGS
This chapter is divided into three main p a r t s :
results of the pretest, results of the main survey, and
discussion of the findings. It should be pointed out
that, as could be understood from the last chapter, the
analysis here is mostly concerned with methodological
issues of scale development. Demographic and psychographic
description of the various PR types will have to wait
until further work can be performed though some limited
findings are discussed.
Pretest Results
Analysis was based upon thirty-eight subjects from
whom useable questionnaire results and interview comments
were received. A summary of the sample's socioeconomic
characteristics is presented in Table 1 . The majority of
the pretest subjects were married, young to middle age,
white women. A majority of them worked full time and
lived in households with incomes of at least $25 ,000 . As
a group, they had a high education level, with half having
a college degree.

The main purpose of the pretest was to determine the
subset of PR statements that best discriminated between
Actual State types and Desired State types. This decision
was based upon judgments concerning interview comments and
subsequent analysis of questionnaire data. Working with
the scores given independently by the two judges it was
determined that the sample was composed of eleven Desired
State types, eleven Actual State types, and sixteen people
who were in-between the two extremes. Analysis was then
made of each of the forty PR statements to ascertain which
ones provided conceptual as well as s t a t i s t i c a l l y
significant different (less than 0.10) response tendencies
for the two extreme PR groups. Results of this analysis
are presented in Table 2. The p-value of the Mann-Whitney
test along with the medians of the two groups were used to
measure the effectiveness of the statements. Where the
results were particularly confusing, consultation of
t-tests were made as well. Primarily, if some evidence
could be found that an item m a d e c o n c e p t u a l and
statistical distinction between the two PR types then it
was retained for use in the main study survey. Using this
approach, half of the statements were eliminated leaving
twenty for further study.
It does not appear that pretest s u b j e c t s were
expressing their need for social approval in either their

interview comments or their responses to PR statements.
The correlation (Spearman) between the interview scores
a s s i g n e d by the j u d g e s and the s c o r e s on t h e
Marlowe-Crowne Social Desirability Scale was 0.13. This
lack of association was confirmed by the correlation of
the Actual State Scale and Desired State Scale with the
Social Desirability Scale. Here, correlations of -0.06
and 0.03, respectively were f o u n d . N o n e of these
correlations were statistically significant at the .05
level.
Survey Results
This section is sub-divided into three parts. The
first part will describe the sample used to gather the
data. In the second part, the results of the factor
analysis and scale development will be discussed. The
final part will focus on how well the i s s u e s of
reliability and validity were met.
Survey Sample
Of the 2000 questionnaires mailed out, 499 usable
forms were returned. This represents a response rate of
twenty-five percent, although that should be considered as
a minimum. It is not known how many of the questionnaires
reached a home with an adult female. The effective
response rate, therefore, could e a s i l y be several
percentage points higher.
64
A summary of the demographic characteristics of the
survey sample is presented in Table 3. It bears
similarity with the pretest sample, with a preponderance
of young to middle age, married white women composing the
group. Over half were either employed full- or part-time,
with over seventy percent describing their occupations as
either "Professional" or "Office, Clerical, Sales." The
total annual household income of the group was high, with
almost sixty-five percent making $25,000 or more a year.
Certainly, the majority of the respondents were from high
socioeconomic groups. However, the sample was not
expected to perfectly reflect the adult female clothes
buying public but merely to have some representation from
a variety of groups.
The sample was also analyzed to note any demographic
differences between the different PR types. (Grouping was
done using the scales discussed in the next section.) The
PR types appeared to be homogeneous with respect to all of
the socioeconomic variables studied except for age and
income, having chi-square significance values of .002 and
.08, respectively. The data indicated a salient
association between age and PR type, though not clearly
positive or negative. That is, the relationship was not
linear. For example, those under the age of twenty-five

were most likely to be Desired State types whereas those
over sixty-five were most likely to be Actual State types.
But, it was not a clear positive trend between those two
extremes. The "curve" in the relationship centered on the
thirty-five to forty-four year olds. As a group, those
middle-aged individuals were the most likely to be Actual
State types and the least likely to be Desired State types.
The relationship between PR types and income was
somewhat more linear, though not without "curves" as well.
It appeared that as incomes increased, greater proportions
of individuals in the income groups were Desired State
types. Specifically, only twenty-four percent of those
making less than $10,000 were Desired State types compared
to forty-eight percent for those making more than $50,000.
The opposite was generally true for Actual State types.
So, age and income may be linked to style of PR.
However, these findings must be r e p l i c a t e d b e f o r e
conclusions are drawn.
Factor Analysis and Scale Development
The initial run of the twenty PR statements using
image analysis and Varimax rotation produced nine factors.
Image analysis tends to produce more factors than other
approaches, with approximately one factor for every two
variables, resulting in several trivial factors (Nie et al
67
1975, p. 482). Only the first two factors had significant
loadings and it is only these two that are presented in
Table 4A.
Seventeen of the variables loaded at the 0.5 level or
better on one of the two factors. Statement #5 did not
load well on any of the factors developed and #30 was
badly split between the first two factors.1 These two were
eliminated and factor analysis was run again. Variables
#16, #24, and #34 were also somewhat split between the two
major factors but it was decided to retain them since they
did not greatly violate the p r e - s p e c i f i e d loading
parameters, which could be considered rather stringent for
exploratory factor analysis.
The results of the second round of factor analysis
are presented in Table 4B. This time the a n a l y s i s
produced eight factors, again with the first two being the
only ones with significant loadings. Factor 1 and factor
2 had eigenvalues of 20.74 and 4.19, r e s p e c t i v e l y .
Together they accounted for 73.5 percent of the total
variance in the set of eighteen variables. Eleven of the
items loaded highest on factor 1 with the remaining seven
loading highest on factor 2. Due to these loadings,
factor 1 can be interpreted as representing the Desired
State construct with factor 2 representing the Actual
State construct.

Factor scores were not d i r e c t l y c o m p u t e d for
respondents due to the u n e x p e c t e d c o n c e p t u a l and
computational complexity. Further, it was felt that use
of the results by others would be more likely if a simple
Likert-type scale was used versus a weighted linear
combination. Therefore, a Desired State Scale and an
Actual State Scale were developed by merely summing the
raw data over the variables that composed each set and
dividing the total by the number of non-zero responses.
This produced scores for each person on the two scales
which varied between one (representing very little of the
particular trait) and seven (representing a great deal of
the trait).
Beyond measuring each respondent's scores on the two
scales, measurement of a person's PR type with relation to
the rest of the s a m p l e was a l s o d o n e . T h i s w a s
accomplished by noting whether a person scored above or
below the median on each of the scales. Desired State
types were empirically defined as those who scored above
the median on the Desired State Scale as well as below the
median on the Actual State Scale. Thirty-four percent of
the sample fell into this category. Actual State types
were classified as those who scored above the median on
the Actual State Scale and below the median on the Desired
State Scale. Thirty-eight percent of the sample was in
70
this group. The remaining twenty-eight percent either
scored high or low on both scales, and were, therefore,
classified as In-between types.
Reliability and Validity
The alpha coefficients calculated for the Desired
State Scale and the Actual State Scale were 0.93 and 0.85,
respectively. Such high scores indicate that the scales
are internally consistent and are precise measuring
instruments.
The initial group of forty statements was considered
to cover most facets of PR and have, therefore, content
validity. However, not all of these items were tested in
the main survey or, if tested, proved significant. The
greater question is then, what is the content validity of
the final scales? It is true that several of the
theoretical dimensions were not empirically verified and,
therefore, missing from the final scales. The Desired
State Scale does not take into account the influence of
friends, marketers, or other purchases on PR. It focuses
on the tendency to want new clothes despite the condition
of one's wardrobe. The Actual State Scale faired
similarly. It focuses on the lack of interest in new
clothes and the perceived failure of promotion to affect
purchase motivation. This scale does not, however,
account for the theoretical d i m e n s i o n of "altered
71
circumstances," such as weight changes or events calling
for new articles of clothing.
Although it may appear that the content validity of
the scales is in question, it should be realized that the
facets which make the greatest difference between PR types
are included in the scales. As indicated in the results
of the pretest, some dimensions are hypothesized to affect
one state or the other, but this is in reference to a
single occurrence of PR rather than a long term tendency.
When the concern is on variables which separate types of
problem recognizers some of the dimensions seem to make
little or no difference. For example, if a person's size
changed thereby prompting a purchase of clothes, we would
theorize that PR had occurred due to a change in actual
state. However, that one incident does not make that
person an Actual State type. The person may frequently
buy new clothes indicating Desired State typification.
The point is that the variables proposed by Engel,
Blackwell, and Kollat ( 1978) are most appropriate for
describing specific instances of PR. However, when the
purpose is to measure personality and behavioral types
that develop over repeated occurrences some of the
variables continue to be valid while others do not.
Therefore, content validity has been adequately attained
for the level of generality for which the scales were
72
developed. Indeed, some confirmation of the scales'
content validity comes from the high level of internal
consistency reported above; i.e., the set of statements in
each scale do measure something in common.
Moderate success was also achieved in establishing
concurrent validity. One method used to measure concurrent
validity was through correlation of pretest subjects'
i n t e r v i e w s c o r e s and the two scale s c o r e s . T h e
correlation (Spearman) between interview scores and the
respective scores on the Desired State Scale was 0.61.
The correlation between the scores on the Actual State
Scale and the respective interview scores was -0.70.
The other approach at measuring concurrent validity
compared the ability of the scales to place pretest
subjects into PR groups on par with the i n t e r v i e w
judgments. As can be noted in Table 5, sixty-eight
percent of the scale p r e d i c t i o n s agreed with the
assessment made from the interviews. The scales seemed to
be most accurate in predicting PR type for those persons
in one of the extreme groups. However, the scales were
too liberal in placing subjects in the extreme groups, and
by consequence, misclassified the In-between types the
most. None of those in either of the extreme groups based
on the interview judgments were misclassified into the
extreme opposite group by the scales. If an "error" was

made it was to classify an In-between type as one of the
extreme types, or vice versa. Though not exceedingly
strong, the scales succeeded in showing evidence of
concurrent validity.
The strongest piece of evidence to indicate that at
least some construct validity existed came from the factor
analysis itself: the hypothesized latent structure of the
multi-item set was confirmed. Two factors representing
two particular constructs were expected and, indeed, very
strong evidence was found attesting to those constructs'
reality. However, some of the other evidence which would
have strongly supported construct validity was lacking.
It was hypothesized that evidence of construct
validity would be shown if correlations of ± .7 or better
could be found between scores on the PR scales and the
respective scores on the Sensation-Seeking Scale. No
correlation was found. Specifically, the correlation
(Spearman) between the Desired State Scale and the
Sensation-Seeking Scale was 0.06. The correlation between
the Actual State Scale and the Sensation-Seeking Scale was
-0.02. Neither of these was significant at the .05 level.
Although the above was planned as the main test of
c o n s t r u c t v a l i d i t y , upon its failure to p r o d u c e
significant evidence a couple of other measures were
substituted. The survey questionnaire gathered data on
75
several other issues, two of which were respondents'
interest in clothing and their enjoyment of shopping.
Measurement of both of these constructs was based on
previously developed scales (Greenberg, Lumpkin, and
Bruner 1982; Schrank and Gilmore 1973). Factor loadings
and alpha coefficients as used in this study are presented
in Table 6. It was hypothesized that there was a
significant relationship between PR type and interest in
clothing. It was expected that the Clothing Interest
Scale would have a positive correlation with the Desired
State Scale and have a negative correlation with the
Actual State Scale. Likewise, it was hypothesized that
there would be a significant though possibly moderate
relationship between PR type and enjoyment of shopping.
The Desired State Scale was expected to be positively
correlated with the Shopping Enjoyment Scale while the
Actual State Scale was e x p e c t e d to be n e g a t i v e l y
correlated with it.
These hypotheses were generally borne out. The
Clothing Interest Scale had correlations (Spearman) with
the Desired State Scale and the Actual State Scale of 0.59
and -0.59, respectively. The Shopping Enjoyment Scale had
correlations with the Desired State Scale and the Actual
State Scale of 0.40 and -0.41, respectively. All of these
correlations were significant at the .001 level.

77
While these results of the testing of construct
validity are not wholly consistent, it is clear that at
least some evidence exists. The confusing nature of these
results as well as other issues will be examined further
in the following section.
Discussion
A question that may be asked about the findings here
is, "what inferences concerning PR type can be made about
the population?" The appropriate answer is "none."
Although the proportions in the survey sample were
estimated and some idea of the accuracy of those estimates
is known, analysis was not based on a true random sample.
Therefore, confidence intervals for population estimates
cannot be calculated. Estimates of population proportions
will have to be made in future studies which have as their
focus external validity rather than internal validity.
Further, estimates will need to be made particularly for
those specific segments which hold some significance to
marketers. For example, if the young adult female segment
is particularly important to a company in its clothing
sales then it could benefit from understanding proportions
of PR types which compose that specific market. Not only
could this knowledge have some inherent value but it could
also have some implications for the company's promotion
strategy, although it is this link between type of PR and
78
type of search behavior that is yet to be empirically
defined.
Another point of discussion concerns the effect of
the orthogonality assumption on the results. This is
important since it is reasonable to assume based on the
theory that Desired State type PR and Actual State type PR
are related. That is, a person who is a Desired State
type is almost sure to not be an Actual State type, and
vice versa. The constructs and, therefore, the factors
could easily be assumed to have negative correlation.
However, by using an orthogonal rotation the factors
p r o d u c e d in the a n a l y s i s here are t h e o r e t i c a l l y
uncorrelated. Several oblique rotations were tried though
none approached simple structure near as well as the
Varimax rotation. It is of interest to note that even
though the factors are supposed to be uncorrelated after
an orthogonal rotation the scales produced from those
factors in this research had a correlation (Spearman) of
-0.58, significant at the .001 level.
A problem of somewhat greater concern is the content
validity of the scales. Although moderate success was
achieved in establishing the PR scales several dimensions
are missing, as mentioned in the above section. There are
several reasons why some of these dimensions have not been
represented in the present scales. Firstly, it is the
79
impression in hindsight that the parameters for using
pretested statements in the main survey may have been too
rigid. Accepting lower statistical and c o n c e p t u a l
differences might have been justifiable in light of the
exploratory nature of the w o r k . If some of these
"marginal" items had been used in the main survey and
loaded well on one of the two main factors then the extra
dimensions would have increased the content validity of
the scales.
A second problem with establishing the content
validity of the scales concerns their correlation; that
is, a variable which loads positively on one of the
factors will usually have a negative loading on the other
factor. (This tendency was consistent and can be noted in
Table 4). Therefore, even though statements representing
a dimension can be theorized to load on a particular
factor, they could load in the opposite direction on the
other factor. With this in mind, a judgment of content
validity may be more correctly made of the scales as a set
rather than individually. In fact, this lends support to
the idea of a composite PR scale which will be examined
later in this section.
Finally, the most important reason why some content
validity was lacking may be due to a d i f f e r e n c e in
specificity between the initial theory and the eventual
80
measurement. Basically, as presented in the four editions
of the EKB model (1968, 1973, 1978, 1982), the theory
proposed variables which might affect one of the two
states in a situation. However, the scales developed here
and the thinking behind them focus on the facets which
reflect the kind of PR a person tends to experience over
time in a particular product category. If the results of
the pretest are any indication, there are dimensions of PR
which do not distinguish between the PR types. The three
such dimensions apparent from the pretest are: the affect
of other decisions on a particular decision (statements #4
and #27), reference group influence (statements #37 and
#38), and altered circumstances (statements #18, #19, #22,
#25, #35, #37, and #40).^ jt can be assumed that these
influences and situations trigger PR despite one's type.
It is the other situations, however, where PR cannot be
assumed that are of primary concern in the development of
measurements.
With respect to the Sensation-Seeking Scale, there
were two problems encountered with it which affected the
results to some extent. One p r o b l e m was with the
administration of the scale: its forced choice nature did
not lend itself for use in a mail survey. Over fourteen
percent of the people simply choose not to respond at all
to one or more of the pairs in the inventory. Apparently,
81
neither alternative in one or more of the pairs accurately
reflected their views. This by itself should not have
affected the results greatly since scores for such persons
were adjusted to account for this situation.
The g r e a t e r p r o b l e m a p p e a r s to be t h a t the
Sensation-Seeking Scale and the PR scales represent two
different levels of measurement. The former measures a
broad personality trait whereas the latter are specific to
one product category. It is not known how much this
affected the results. It does seem unusual, however, that
at least some nominal level of correlation was not found.
Since the association between sensation seeking and PR is
still valid in t h e o r y , it is s u g g e s t e d that this
relationship be re-examined in the future with greater
attention given to the methodological issues raised here.
The final point of d i s c u s s i o n c o n c e r n s the
justification for and development of a composite PR scale.
Some reasoning for a composite scale was made above: that
the desired state and the actual state constructs are
highly related, that the scale scores have proven to be
correlated, and that some variables theorized to load on
one of the factors ended up loading in the opposite
direction on the other factor. A further reason for just
one scale rather than two is the greater ease of use;
i.e., one scale is simply easier to administer, analyze,
82
and interpret than two. If the internal consistency of
the one scale is as good or better than the two separate
scales then that would indicate the items have much in
common and appear to measure the same basic construct. In
this case, the alpha coefficient for the combined Desired
State Scale and Actual State Scale was 0.93. With such a
high reliability it is even possible that some of the
items which are conceptually redundant might be eliminated
without seriously affecting the internal consistency.
A further indication of the composite scale's value
is its correlation with the Shopping Enjoyment Scale and
the Clothing Interest Scale. The correlations (Spearman)
with the PR Scale were 0.45 and 0.66, respectively. Both
were significant at the .001 level. Possibly even more
important was the PR Scale's 0.70 correlation with the
judges' scores of pretest interviews. This was also
significant at the .001 level. These correlations provide
some evidence that the PR Scale is not only as reliable as
the two separate scales but just as valid.

CHAPTER V
CONCLUSIONS
It has been the purpose of this investigation to
determine if theoretical justification for the PR concept
could be found, and if so, to develop scales adequate for
its measurement. This has largely been accomplished.
Homeostasis has been proposed as the reason why PR occurs:
to resolve c o n s u m p t i o n i m b a l a n c e s . Not only has
homeostasis been found to be consistent with existing
description of PR but it implies other relationships that
should exist, namely that consumers develop styles of PR
over time specific to particular product categories. Based
on the results of the pretest interviews and the mail
survey, scales have been developed for the measurement of
the two main forms of PR: the Desired State type and the
Actual State type. The scales have shown evidence of being
reliable and valid, with the former being especially
strong.
There may be some application of these findings to
general decision making theory, whether it be in an
individual or organizational context. For example, there
may be styles of PR in business management. That is, some
managers do not deal with problems until the very last
85
86
moment when attention and resolution become crucial. Then,
there are others who seem to anticipate problems and make
plans to deal with them long before a breakdown or crisis
develops. The former relates to Actual State types and the
latter to Desired State types. C e r t a i n l y , such a
hypothesis requires verification but the point is that
there is now reason to believe that such styles exist and
affect problem-resolution behavior.
Although it has not been captured in a quantitative
sense, a phenomenon of some interest was observed in the
course of this research which deserves m e n t i o n i n g .
Specifically, some women expressed that they went shopping
for clothes as a result of feeling sad, bored, or after
experiencing some other mild emotional dissonance. In
other words, there was no apparel problem as such; i.e.,
neither the desired state nor the actual state for clothes
shifted significantly though a purchase still resulted due
to a non-clothing related problem. It is possible that
some moods and states of emotion present problems which are
not tackled directly. Rather, the purchase of clothing is
perceived as a positive experience and one which might
offset the emotional disturbance. So, the purchase is a
surrogate—it appears to solve one problem where in fact it
is intended to satiate another. That is why any number of
purchases might serve the purpose though clothing seems to
87
be particularly attractive. Admittedly, these thoughts are
mere speculation but they represent hypotheses worthy
of further development and investigation.
Among other suggestions for further research is that
c a u s a l m o d e l i n g be used to e m p i r i c a l l y test the
determinants of PR as given by Engel, Kollat, and Blackwell
(1968, 1973, 1978, 1982). At this point the information we
have, as insightful as it is, is based more on speculation
than research. It is proposed here that any modeling that
is done incorporate the variables which determine the
desired state (e.g., reference group influence, the effect
of other decisions, novelty seeking, motive activation),
the variables which determine the actual state (e.g.,
dissatisfaction with a current solution and running out of
a previous supply), and variables which can influence both
states (e.g., altered family or financial circumstances and
the influence of marketers). To account for the insights
gained from this research and to illustrate the other
relationships needing investigation, the model of the PR
process presented in Figure 2 is updated in Figure 3.
A similar suggestion can also be made concerning PR
s t y l e s — f u r t h e r research is needed to s p e c i f y the
determinants. Although there might be some overlap in the
variables relevant at the various levels of abstraction
(e.g., a specific instance of PR versus a style of PR

developed over time), the sets are not likely to be exactly
the same. The work reported here offers some indication of
the variables working in the apparel context which affect
the development of PR styles. With this foundation the
next step can be causal modeling. The following are
variables suggested for inclusion in such a model: 1) the
desire for novelty, 2) product interest, 3) satisfaction
with status quo, 4) degree of inner/other directedness, 5)
age, and 6) income. Although this list is biased by the
product category used in this research it should be
sufficient for exploratory work in other product areas.
Certainly, it would be quite beneficial to the
theory's development if scales could be successfully
constructed for other product categories. The reporting of
reliability and validity measurement would be extremely
helpful. The product categories which lend themselves to
this sort of study are those where Actual State types and
Desired State types hypothetically exist in more than
nominal proportions. Some categories that would seem to be
appropriate for study are furniture, various large and
small appliances, and automobiles. It is this last category
that is especially fitting for study due to the ill health
of the industry and the apparent p r e c a r i o u s n e s s of
demand.
90
Once PR scales have been developed for several product
categories, it will be of interest to note their degree of
intercorrelation. As previously stated, it is not expected
that consumers are characterized by the same sort of PR for
widely varying product categories but the exact nature of
the pattern requires examination. Clarification is also
needed to understand the effect that type of PR has on type
of information search. That is, it is possible that PR
type and search style are related. In fact, they may be
related so closely that the link holds across product
categories despite how a person's PR changes. In other
words, there may be some unique characteristics of Actual
State type search behavior despite the category involved,
and likewise for Desired State types.
Indeed, the PR/search link is a critical one to verify
if the full practical value of this piece of research is to
be received. Although there is practical value in under-
standing a person's PR type, there is greater value in
understanding the effect it has on search activity. This
is because the marketer would learn not only why a person
is typically in the market for a certain category of
product but could also learn how and where that type of
problem recognizer searches for solutions. How do PR types
differ in successfulness of internal search? And, in terms
of external search, do the PR types differ in their
