1. Structural equation modeling in a nutshell
Structural equation modeling (SEM) has seen a dramatic rise in
attention and utilization across a variety of scientific disciplines
such as strategic management (Shook, Ketchen, Cycyota, &
Crockett, 2003), marketing (Chin, Peterson, & Brown, 2008) and
psychology (MacCallum & Austin, 2000) over the last decade (Hair,
Ringle, & Sarstedt, 2011b). Statistically, SEM represents an
advanced version of general linear modeling procedures (e.g.,
multiple regression analysis), and is used to assess whether a
hypothesized model is consistent with the data collected to reflect [the]
theory (Lei & Wu, 2007, p. 34). While SEM is a general term
encompassing a variety of statistical models, covariance-based
SEM (CB-SEM) is themore widelyused approach in SEM, and many
researchers simply refer to CB-SEM as SEM. This reference is nave,however, because partial least squares (PLS) is also a useful and
increasingly applied approach to examine structural equation
models (Hair, Sarstedt, Ringle, & Mena, 2012).
Structural equation modeling is a multivariate analytical
approach used to simultaneously test and estimate complex
causal
relationships
among
variables,
even
when
the
relationships
arehypothetical,ornotdirectly observable (Williams,Vandenberg,
& Edwards, 2009). Concurrently combining factor analysis and
linear regression models, SEM allows the researcher to statistically
examine the relationships between theory-based latent variables
and their indicator variables by measuring directly observable
indicator variables (Hair,Hult,Ringle,& Sarstedt,2014).WhileSEM
is similar to multiple regression in the sense that both techniques
test relationshipsbetweenvariables, SEM is able to simultaneously
examine multi-leveldependence relationships, where a dependent
variable becomes an independent variable in subsequent relationships
within
the
same
analysis (Shook, Ketchen, Hult, & Kacmar, 2004, p.
397) as well as relationships between multiple dependent
variables (Joreskog, Sorbom, du Toit, & du Toit, 1999).
The objective of this article is to evaluate the benefits and
limitations of SEM in general, and in family business research in
particular, by directly comparing two major approaches tostructural modeling covariance based SEM (CB-SEM) and
variance-based SEM (PLS-SEM) (Sarstedt, Ringle, Smith, Reams, &
Hair, 2014; Sharma & Kim, 2013). While CB-SEM and PLS-SEM are

Structural equation modeling (SEM) has become the methodology of choice for many family businessresearchers investigating complex relationships between latent constructs, such as family harmony or
family cohesion. Its capability to evaluate complex measurement models and structural paths involving
a multitude of variables and levels of constructs has enabled family business researchers to investigate
complex andintricaterelationships thatpreviously couldnot be easily untangledand examined. Inmany
cases,however, researchers struggle tomeet some of the challenging requirements of covariance-based
SEM(CB-SEM), themost commonly used approach to SEM, such as distribution assumptions or sample
size. In this article, we point out the benefits and disadvantages of CB-SEM, and present a comparison
with partial least squares-SEM (PLS-SEM) using an identical sample. We find that even though both
methods analyze measurement theory and structural path models, there are many advantages in
applying PLS-SEM.

(target) endogenous constructs (Hair et al., 2014, p. 14; Ringle,
Sarstedt, Hair, & Pieper, 2012).CB-SEM, on the other hand, follows a
maximum likelihood (ML) estimation procedure and aims at
reproducing the covariance matrix [i.e., minimizing the difference
between the observed and estimated covariance matrix], without
focusing
on
explained
variance (Hair et al., 2011a, p. 139). In other
words, with CB-SEM, the R2 is a by-product of the overall statistical
objective of achieving good model fit (Hair et al., 2014).
Using a sample of 253 Swiss consumers surveyed in 2012
evaluating the effects of corporate expectations on the perceived
level of expertise and trustworthiness of family-owned companies,
we apply both CB-SEM and PLS-SEM to analyze the data. This
approach enables us to not only compare the requirements of each
method, the way in which the models are specified, and the
applicability and user-friendliness of available software, but also
the results and interpretations.
The remainder of this article is structured as follows: first, we
briefly highlight the most important benefits of SEM. We then
summarize the results of several important articles in family
business research that utilized SEM, and point out how SEM
contributed to the findings of these studies. Third, the research
context of the example used in this study is briefly described, and
the hypotheses as well as an outline of the methodology are
presented. Fourth,wediscuss the results from theCB-SEM and PLS-SEM analyses. Finally, practical observations and conclusions are
provided, and limitations and suggestions for further research are
presented.
2. The benefits and limitations of SEM
2.1.
The
benefits
of
SEM
The
question
of
why
researchers
might
want
to
use
SEM
is
quite
simple. The process of applying SEM enables researchers to more
effectively evaluate measurement models and structural paths,
particularly when the structural model involves multiple depen-
dent
variables,
latent
constructs
based
on
multi-item
indicator
variables, and multiple stages/levels of constructs in a structuralmodel. While there are many reasons to use SEM in social sciences
research, we consider the following to be the most relevant.
When
dealing
with
latent
constructs
and
complex
models: Many
constructs
investigated
in
the
social
sciences
are
latent
constructs
that cannot be observed, or measured directly. Examples include
family influence and family cohesion. Moreover, especially at the
theory
development
and
testing
stages
there
may
be
multiple
constructs
and
interactive
effects
resulting
in
a
complex
model.
While a latent construct may be measurable to some extent by
means of a directly observable indicator variable (e.g., degree of
family
ownership,
number
of
family
members
in
management),
these
indicator
measures
may
not
reflect
the
latent
variable
entirely accurately, which means the measurement will contain
error
as
will
the
results.
By
explicitly
assessing
error
in
thestructural
model,
SEM
provides
a
powerful
means
of
simultaneously
assessing
the
quality
of
measurement
and
examining
causal
relation-
ships among constructs (Wang & Wang, 2012, p. 1). So while
multiple regression analysis assumes there is no error in the data,
SEM
recognizes
and
accounts
for
the
error
in
each
measured
item
in
an
effort
to
improve
the
accuracy
of
findings.
Additionally,
the
SEM approach is designed to consider interactive effects and
complex models to find an optimal model that reduces cross-
loadings
and
identifies
the
higher
loadings
for
relevant
measures.
When
analyzing
direct,
indirect,
and
total
effects:
SEM
facilitates
the assessment of direct, indirect and total effects. Direct effects
include relationships between independent and dependent vari-
ables,
e.g.,
family
ownership
has
a
direct
positive
effect
on
firm
performance.
Indirect
effects
involve
relationships
between
independent and dependent variables that are mediated or
moderated by some other variable, e.g., the effect of family
ownership on firm performance is moderated by the owning
familys involvement in management. Total effects relate to the
sum of two or more direct or indirect effects. In comparison to
other statistical procedures such as regression, SEM enables
researchers to not only simultaneously assess the relationships
between multi-item constructs, but also to reduce the overall error
associated with the model. In contrast to multiple regression
analysis, which cannot directly deal with the measurement issues
of multi-item constructs, SEM is specifically designed to improve
multi-item measurement models by directly accounting for error.
When assessing structural models: While regression also allows
researchers to evaluate structural relationships using path analysis
(examining each path separately), SEM facilitates simultaneous
analysis of all structural relationships (i.e., relationships or paths
among numerous variables, e.g., family ownership, family cohe-
sion and performance), and is an inherently simpler approach that
leads to more accurate results. CB-SEM and PLS-SEM use different
approaches when assessing the quality of a structural model. For
example, with CB-SEM fit is based on accurately estimating the
observed covariance matrix, while with PLS-SEM fit is based upon
accounting for explained variance in the endogenous constructs
(Hair et al., 2014). As a result of model fit requirements, however,CB-SEM often eliminates relevant indicator variables, thereby
reducing the validity of constructs. In contrast, PLS-SEM creates
composite constructs that generally include additional theory-
based indicator variables (Rigdon, 2012), while still optimizing
predictive accuracy and relevance. Also, PLS-SEM analyses can
easily incorporate single-item measures, and can obtain solutions
to much more highly complex models, i.e., models with a large
number of constructs, indicators and structural relationships (Hair
et al., 2014; Ringle, Sarstedt, & Hair, 2013).
2.2. The limitations of SEM
The
fact
that
modern
SEM
software
(such
as
AMOS,
LISREL
and
SmartPLS) does not require profound statistical knowledge hasmade investigation of complex statistical problems accessible to
non-statisticians (Babin, Hair, & Boles, 2008; Hair, Black, Babin, &
Anderson,
2010). Yet,
while
ease
of
access
to
SEM
has
increased
the
number
of
meaningful
and
valuable
contributions,
recent
reviews
of SEM applications provide grounds for criticism of methodologi-
cal flaws and shortcomings in the execution of SEM in many
contributions
(e.g.,
Hair
et
al.,
2012;
Williams
et
al.,
2009).
Being
a
highly
sophisticated
statistical
tool,
insight
and
judgment
are
crucial elements of its use (Shook et al., 2004, p. 397). Thus, to
obtain meaningful and valid results it is essential to understand
when
it
is
appropriate
to
use
SEM,
its
requirements
and
interpretation,
and
also
the
potential
trade-offs
when
compared
to other methods.
When
unable
to
correctly
identify
a
research
model:
In
the
case
ofCB-SEM
in
particular,
since
it
is
a
confirmatory
approach,
the
method
requires
the
specification
of
the
full
theoretical
model
prior to data analysis. The researcher(s) must therefore define the
exact number of dependent (endogenous) and independent
(exogenous)
variables
used
in
the
theoretical
model,
the
relation-
ships
between
these
latent
variables,
the
type
of
measurement
model (formative or reflective), and the number of indicator
variables required to ensure a valid and reliable measure of all
constructs
(e.g.,
Williams
et
al.,
2009).
Only
when
a
model
is
correctly
specified
can
all
parameters
be
estimated
(Lei
&
Wu,
2007). Thus, if the model lacks a sound theoretical foundation, and
if the direction of the relationship between variables cannot be
determined,
CB-SEM
should
not
be
the
method
of
choice.
In
contrast,
PLS-SEM,
which
is
particularly
suitable
for
early-stage
C.B. Astrachan et al./Journal of Family Business Strategy 5 (2014) 116128 117

3/13
theory development and testing (Hair et al., 2014; Ringle et al.,
2013), permits examination of constructs and relationships in
complex structural models. Since the primary purpose in theory
development is to find relationships, their directions and
strengths, as well as observable measures, PLS-SEM is appropriate.
The model fit constraints of CB-SEM are more appropriate for
established theory testing and confirmation, but require a
substantially larger sample size, which may not be available in
general, and particularly at the early stages of theory development
in the context of family research.
When
experiencing
data
collection
constraints: Recommenda-
tions regarding the ideal sample size for SEM analysis range from
50 to 200 observations (e.g., Anderson & Gerbing, 1988; Kline,
2005). The appropriate sample size for SEM models depends first
on the method used. Specifically, CB-SEM requires larger samples
than PLS-SEM because relationships between all variables must be
assessed (i.e., a full information approach),whilewith PLS-SEM the
model is separated into different smaller components (a compo-
nent for each construct in the model; hence the name partial least
squares). In comparison with CB-SEM, which imposes rigid sample
size restrictions on the researcher(s), PLS-SEM works efficiently
with
small
sample
sizes
and
complex
models
and
makes
practically
no
assumptions
about
the
underlying
data
[distributions] (Hair et al.,
2014;Ringle et al.,2013). Thismakes PLS-SEM particularly suitablefor family business research, where researchers often experience
data collection constraints and struggle with low response rates. In
PLS-SEM, the guideline is that sample size should be ten times the
number of arrows pointing at a construct (Hair et al., 2014). In
contrast,CB-SEM requires a sample size offive times thenumber of
indicators included in the original model (e.g., a CB-SEM model
with 40 indicator variables on three constructs requires a sample
size of 200 (5 40), but if those 40 indicators are associated with
the same three constructs and two exogenous constructs are
predicting a single endogenous construct, then the required
sample size with PLS-SEM is 20 (2 10); i.e., arrows pointing
from the two exogenous constructs to the one endogenous
construct).
When data are not normally distributed: The CB-SEM maximumlikelihood approach, like many other multivariate statistical
methods, requires multivariate normality. In contrast, PLS-SEM
does
not
require
normally
distributed
data
(Hair
et
al.,
2014),and
is
therefore
the
more
appropriate
method
of
SEM
for
many
social
science studies, including family business, where data are often
non-normally distributed (e.g., distribution of ownership among
US
companies;
Astrachan
&
Shanker,
2003).
Moreover,
when
data
are
categorical
or
ordinal
(quasi-metric),
or
includes
single
item
measures, PLS-SEM can be used (Hair et al., 2014).
In sum, SEM approaches offer a range of unique benefits, as
compared
with
first
generation
statistical
procedures.
There
may
be
situations,
however,
where
a
simpler
approach
like
regression
analysis might be adequate, or when investigating a simple model
involving
two-stage
(single
path)
models.
However,
regressionanalysis
does
not
directly
permit
assessment
of
measurement
characteristics
so
latent
constructs
must
first
be
converted
to
some
composite or average of individual measures, such as factor scores
from an EFA or summated scores. SEM based models inherently
include
evaluation
of
individual
measures
and
retention
of
relevant
indicators
at
appropriate
loading
levels,
e.g.,
at
a
level
of .70 or higher (Hair et al., 2010).
3.
SEM
in
family
business
research
Despite the fact that SEM is an increasingly popular approach in
business research and related social sciences, family firm
researchers
have
used
the
method
sparingly
(Wilson
et
al.,
2014).
Several
family
business
researchers
have
called
for
more
sophisticated and rigorous statistical analysis techniques, such as
SEM (e.g.,Debicki,Matherne,Kellermanns,&Chrisman,2009;Dyer
& Dyer, 2009; Westhead & Howorth, 2006). One assessment of
empirical articles published in family business research revealed
that only 13 empirical studies investigating family businesses
publishedbetween1989 and 2013used SEMmethodologies, seven
of which (from a total of 183 empirical articles) were published in
Family Business Review. Interestingly, a broader EBSCO database
search using the keywords family business and structural
equation modeling resulted in considerably larger numbers
however, many of these contributions only point out in their
discussion or contribution sections that using a SEM approach
wouldprovide additional insights,and that further research should
look into applying these methodologies. The low number of actual
applications using SEM methods mostly CB-SEM based is a
particularly unfortunate shortcoming given the possibilities these
methods offer to family business research, as some of the widely
cited examples presented below illustrate (Wilson et al., 2014).
Aspects
related
to
causality: Mustakallio, Autio, and Zahra
(2002), analyzing a sample of 192 Finnish family firms, explored
the effects of both contractual (formal control) and relational
(social control) governance systems on strategic decision quality
and commitment. Using CB-SEM, the authors evaluated the fit of
the overall measurement model as well as the strength andsignificance of the relationships (or paths) between the exogenous
and endogenous variables. For instance, the results suggest that
family size has a negative effect on the degree of social interaction
within the family, i.e., the larger the family the fewer family
members interact with each other. Moreover, while the relation-
ship between board monitoring and the board commitment to
strategic decisions was hypothesized to be positive the results did
not confirm the relationship. In sum, SEM can shed light on the
theoretical causality of relationships between latent and observ-
able variables, and can help researchers decide whether to accept
or reject hypothesized relationships.
Theory testing and scale development: In addition to analyzing
relationships
between
multiple
variables
or
constructs,
SEM
is
particularly useful for testing theoretical models with non-experimental data (Bagozzi, 1980). Astrachan, Klein, and Smyrnios
(2002; see also Klein, Astrachan, & Smyrnios, 2005) used CB-SEM
when
developing
their
continuous
(rather
than
dichotomous)
F-
PEC
scale
of
family
influence,
which
today
is
one
of
the
few
widely
accepted, measureable, and validated conceptualizations of fami-
ly-owned business (see also Holt, Rutherford, & Kuratko, 2010).
The
F-PEC
scale
is
an
index
of
family
influence,
measured
by
three
dimensions
(power,
experience,
culture),
which
include
nine
subscales with 23 corresponding indicator variables (Power: 4;
Experience: 6; Culture: 13). The authors used CB-SEM when
developing
the
original
scale
to
confirm
the
theoretically
developed
model
with
data
(Klein
et
al.,
2005,
p.
327).
In
comparison
to
other
statistical procedures, SEM models enable researcher(s) to
evaluate
complex
models
with
regard
to
their
compatibility
(fit)with
all
the
relationships
(covariances)
in
the
data
set.
By
calculating
a
range
of
goodness-of-fit
statistics,
CB-SEM
can
assess
whether the theoretical model is confirmed. While scale develop-
ment is possible based on exploratory factor analysis (EFA), an
inherent
advantage
of
SEM
is
that
it
includes
Confirmatory
Factor
Analysis
(CFA),
which
is
considered
a
superior
approach
to
scale
development (Hair et al., 2010). SEM based modeling enablesmore
precise evaluation of indicator variable loadings as well as
reliability
and
validity
of
measurement
models.
Inclusion
of
mediating/moderating
effects: SEM
approaches
are
particularly useful when examining mediating and moderating
effects (Hair et al., 2010). Using a sample of 163 Swiss companies,
Memili,
Eddleston,
Kellermanns,
Zellweger,
and
Barnett
(2010)
investigate
the
mediating
effects
of
entrepreneurial
risk
taking

(willingness to undertake high risks) and family firm image
(promotion of the firms family background) on the relationships
between the degree of family ownership and the owning familys
identification with the firm (independent variables) and firm
performance (dependent variable). Using a CB-SEM approach, and
comparing the fit indices of both a fully and partially mediated
model enabled the authors to show that a fully mediated model fit
our data best, showing, for example, that the possible relationship
between family expectations and family firm performance was fully
mediated
by
family
firm
image
and
risk
taking (Memili et al., 2010,
p. 206).
Besides the three examples presented above, other interesting
possible applications in familybusiness researchmight include the
examination of group differences such as differences between
family and non-family firms but also, and possibly more
important, within the family firm group cross-cultural compar-
isons (e.g., family firms in Germany vs. the United States), or the
investigation of differences between generations, for example in
terms of attitudes, values, or expectations. Despite the fact that
family firms are far from being a homogeneous group of
organizations, and numerous calls for within-group comparisons,
most studies thus far focus on the differences between family and
non-family companies. Given that family business researchers
often experience theory specification and data collection con-straints, SEM approaches and in particular, PLS-SEM may be a
valuable tool for research in the family business context.
4. Research context
To illustrate how the applicability and the results of CB-SEM
and PLS-SEM compare, we applied both SEM approaches to the
same research context. In this example, we examine the
relationship
between
organizational
reputation
and
corporate
credibility. Specifically, we investigate whether two distinct
dimensions of reputation,namely social expectations and business
expectations, lead to organizational trust, i.e., the degree to which
individuals
consider
an
organization
to
be
trustworthy.
Further-
more, we test if perceived expertise acts as a mediating factor.Corporate credibility refers to the expertise and trustworthi-
ness a potential customer attributes to an organization, or in other
words,
the
extent
to
which
consumers
feel
that
the
firm
has
the
knowledge
or
ability
to
fulfill
its
claims
and
whether
the
firm
can
be
trusted to tell the truth (Newell & Goldsmith, 2001, p. 235).
Corporate credibility has been shown to influence customer
attitudes
and
ultimately
purchase
decisions
and
therefore
firm
performance
(Fombrun,
1996).
Being
viewed
as
credible
(i.e.,
as
experienced and trustworthy), is therefore a source of competitive
advantage for companies. This phenomenon may be particularly
relevant
in
the
context
of
family
firms
as
this
type
of
governance
structure
has
repeatedly
been
characterized
by
its
ability
to
create
long-term, trust-based relationships (Tagiuri & Davis, 1996; Ward,
1997).Recent
research
has
shown
a
growing
scholarly
interest
in
the
areas
of
family
firm
reputation
and
branding,
and
findings
indicate
that stakeholders are likely to perceive family-owned businesses
differently, and possibly view them in a more positive light as
compared
with
publicly
listed
companies
(e.g.,
Binz,
Hair,
Pieper,
&
Baldauf,
2013;
Carrigan
&
Buckley,
2008;
Craig,
Dibrell,
&
Davis,
2008; Kashmiri & Mahajan, 2010). Several studies have suggested
that a distinct family firm brand, which refers to the active
promotion
of
a
firms
family
background
(e.g.,
SC
Johnson:
A
family
company),
may
lead
to
superior
organizational
reputation,
and
that such distinct family firm reputation could be a unique asset
that family firms can leverage to obtain a competitive advantage
(e.g.,
Craig
et
al.,
2008;
Zellweger,
Kellermanns,
Eddleston,
&
Memili,
2012).
While
the
research
is
inconclusive
as
to
what
leads
to a superior reputation, it has been suggested that it may be the
owning familys dedication to the companys ongoing success and
survival that strengthens the firms reliability and increases
stakeholders trust in the organization (Dyer & Whetten, 2006;
Miller, McLeod, & Young, 2001; Tagiuri & Davis, 1996).
Another driver of stakeholder trust may be the continuity and
stability that a family firms long-term existence implies. The fact
that a company has been around for decades, implying that
knowledgeand experiencehavebeen accumulated and transferred
across generations, creates a perception of expertise (Miller & Le
Breton-Miller, 2005; ODonnell, Carson, & Gilmore, 2002; Zahra,
Hayton, Neubaum, Dibrell, & Craig, 2008). Accordingly, family-
owned companies are assumed to be viewed as more trustworthy
than publicly-owned firms, which might lead to higher levels of
customer satisfaction, loyalty and trust (e.g., Carrigan & Buckley,
2008; Dyer & Whetten, 2006; Memili et al., 2010; Orth & Green,
2009; Tagiuri & Davis, 1996; Ward, 1997).
For this study, we draw from and extend the findings from a
previous study examining the effects of distinct family firm
reputation on customer preferences (Binz et al., 2013). In this
research, we use the adapted reputation construct with two
dimensions, which was identified in the previous study based on
exploratory factor analysis. The social expectations dimension
refers to how a company conducts its business, while the businessexpectations dimension refers to what a company does in order to
be successful. As suggested by prior research, we assume that
satisfaction of customer expectations leads to trust, e.g., if a
company claims to have high quality standards, and customers are
satisfied with the quality of the products they purchased, the
company fulfilled their claim and is deemed trustworthy.
Furthermore, we assume that a high level of perceived expertise
(i.e., the company is skilled, has substantial experience, and broad
expertise) strengthens the relationship between an individuals
expectations (e.g., this company is a loyal employer, the company
develops innovativeproducts and services) and the degree to which
they trust that an organization will fulfill their claims.
The
literature
and
its
synthesis
suggest
the
conceptual
model
shown in Fig. 1 and the following hypotheses.
H1. Business expectations are positively related to organizational
expertise.
H2.
Business
expectations
are
positively
related
to
organizational
trustworthiness.
H3. Social expectations are positively related to organizational
expertise.
H4. Social expectations are positively related to organizational
trustworthiness.

5. Methodology
5.1.
Measures
To investigate the relationship between distinct family firmreputation and perceived trustworthiness of family businesses, a
standardized questionnaire was developed based on two estab-
lished scales. One scale was the Fombrun, Gardberg, and Sever
(2000) Reputation Quotient Scale, which consists of six dimen-
sions of corporate reputation, namely emotional appeal, products
and
services, vision
and leadership, workplace
environment, social
and environmental responsibility, and financial performance ,
measured with 7-point Likert scales. The original wording of
the scale items was adapted by replacing the term organization
with family firm in each question to fit the family business
context (see also Holt et al., 2010; Zellweger, Nason, & Nordqvist,
2012).
The second scale was Newell and Goldsmiths (2001) Corporate
Credibility
Scale,
a
self-report
scale
designed
to
measurecorporate credibility or the amount of expertise and trustworthi-
ness
that
consumers
perceive
in
a
corporation
(p.
235).
The
scale
consists
of
two
dimensions
(4
items
each),
namely
expertise
and
trustworthiness, which were both assessed by 7-point-Likert
scales. In addition to the two scales described above, respondents
were
asked
to
provide
basic
demographic
information,
including
whether
they
had
previously
worked
in
a
family
or
non-family
firm
(see Binz et al., 2013 for details).
5.2.
Sample
profile
An invitation to participate in the online survey on unipark.de
was sent to 480 potential respondents, all of which were personal
and
professional
acquaintances
of
24
lecturers
working
at
LucerneUniversity
of
Applied
Sciences
in
Switzerland.
Two
follow-up
emails were sent after 14 and 21 days, respectively, and 266
respondents followed the link and completed the questionnaire.
After
eliminating
respondents
that
failed
to
complete
the
questionnaire,
a
total
of
174
usable
responses
remained,
repre-
senting an overall response rate of36.25%. The sample size exceeds
the minimum required for the application of either CB-SEM or PLS-
SEM
(Hair
et
al.,
2014;
Hair
et
al.,
2010).
The
sample
diversity
was
satisfactory
with
51%
of
all
respondents
being
male.
The
average
age of the sample was 38 years. A test for non-response bias
(Armstrong & Overton, 1977) did not reveal significant differences
between
early
and
late
respondents.
5.3.
Initial
measurement
model
evaluation
In
the
Binz
et
al.
(2013)
study,
CFA
was
used
to
examine
the
dimensionality, reliability and validity of the reputation con-
structs. When the CFA did not achieve acceptable fit, and thus the
data
did
not
reflect
the
six
dimensions
proposed
by
Fombrun
et
al.
(2000), it
was
necessary
to
re-assess
the
theoretical
foundation
of
the scales. Subsequently, an EFA was executed, and after several
iterations and the removal of weaker items, an empirically
validated
two-factor
solution
emerged
(see
Table
1).
Based
on
a
qualitative
assessment
of
the
loadings,
the
new
constructs
were
named social expectations (SE, related to how a company does
business) and business expectations (BE, related to what a business
does
in
order
to
be
successful),
which
differs
slightly
from
the
original
wording
used
in
the
previous
study
(see
Appendix
for
list
of
questions).
The
SE
and
BE
constructs
along
with
the
Expertise
and Trust constructs were then used to run the CB-SEM and PLS-SEM analyses.
6. Results from the SEM analyses
In this section we discuss the results from applying the CB-SEM
and PLS-SEM methods separately to examine the theoreticalmodel
and
hypotheses.
We
present
an
overview
of
our
approach
and
findings
as
well
as
comparative
results.
We
also
discuss
the
specific
findings to evaluate the theoretical model and delineate the
strengths and limitations of the two SEM approaches, as indicated
by
this
study.
As
a
preliminary
step
the
data
was
examined
for
kurtosis
and
skewness to obtain insights about the distributional character-
istics.
This
step
is
particularly
important
for
CB-SEM
since
itassumes
normality
in
the
data,
but
not
for
PLS-SEM
since
normality
is
not
assumed.
Where
both
Kurtosis
and
Skewness
fall
within
a
range of 1 to 1, data are considered within an acceptable range
(Hair, Celsi, Money, Samouel, & Page, 2011). In this case, Kurtosis
for
5
of
25
parameters
fell
outside
the
normal
range,
while
skewness
for
the
sample
was
generally
acceptable.
The
data
were
therefore somewhat close to a normal distribution but a note of
caution about checking distribution normality is necessary for the
CB-SEM
analysis,
and
for
this
type
of
analysis
in
general.

Hinkin, 1998) using the AMOS 20 software. As a preliminary step a
congeneric model was examined for model fit, reliability, and
convergent validity and discriminant validity. The model consisted
of four constructs with 25 indicators Business expectations
(BE) = 9 indicators; Social expectations (SE) = 8 indicators; Exper-
tise (EXP) = 4 indicators; and Trust (TRU) = 4 indicators, as shown
in Fig. 2.
The results of the initial CFA revealed a lack of fit (x2 = 556.4;
DF = 269; p = .000, CFI = .857; RMSEA = .079). A systematic process
of examining the loadings and removing indicators with loadings
below .70 was followed (Hair et al., 2010). To achieve acceptable
modelfit itwasnecessary toeliminate 16of theoriginal 25 indicator
variables, including the reduction of the expertise construct to a
single item measure. An interim CFA model with a three-indicator
expertise construct was examined but two indicators exhibited
squared loadings below .40and an AVE >.50 could not be achieved.
The chi-square for the final 9 indicator, three construct model was
44.912 with 24 degrees of freedom, and a p = .006 (since the
expertise construct had only a single item, itwasnot included in the
final CFA). The comparative fit index (CFI) was .973 and RMSEA was
.071.Acceptable ranges for CFI are .9orhigher,and forRMSEA .08or
less.Theoverall modelfit for themeasurement modelwas therefore
within recommended ranges (Byrne, 2010; Hair et al., 2010).
Convergent validity and reliability are shown in Table 2.Scale items loaded on their respective factors with loadings
ranging from .69 to .87 (Hair et al., 2010). The average variance
extracted (AVE) ranged from .54 to .63, confirming convergent
validity and implicitly, content validity. Composite reliabilities
ranged from .78 to .84 demonstrating reliability for all constructs.
Table 2 also displays the results for the FornellLarcker procedure(Fornell & Larcker, 1998) to assess discriminant validity. Discrimi-
nant validity is satisfactory for all constructs except the relation-
ship between Trust and SE. The result was not unexpected,

however,
since
it
represents
a
relationship
between
an
exogenous
construct and an endogenous construct. Examination of theindicators for these constructs shows the content in general is
distinct from a face validity perspective as well as based on the
literature
(Fombrun
et
al.,
2000;
Newell
&
Goldsmith,
2001).
In
sum,
the
three-construct
model
was
considered
satisfactory
in
terms of content and convergent validity, discriminant validity,
and composite reliability.
The
next
step
in
CB-SEM
is
to
analyze
the
structural
model.
Fig.
3
shows
the
model
tested
and
the
path
coefficients
as
well
as
R2
for the endogenous constructs. The chi-square for the structural
model is 58.99 with DF 30 resulting in normed x2 of 1.966 and a
p
=
.001.
A
normed
x2 of
2
or
less
suggests
the
p
=
.001
is
due
to
sample
size
and
not
to
lack
of
fit.
The
CFI
is
.969
(.9
or
greater
recommended) and RMSEA is .075 (.08 or less recommended).
These
fit
measures
are
comparable
to
those
obtained
with
the
CFA.The
path
coefficients
are
all
significant
at
the
p
=
.000
level,
with
the
exception
of
the
Business
expectations
to
Trust
path
at
p
=
.129,
and the Business expectations to Expertise path which is p = .037.
The SE to Expertise and Trust path coefficients of .54 and .61,
respectively,
are
relatively
stronger
than
the
paths
from
BE
to
Trust
of .12, BE to Expertise of .21, and Expertise to Trust of .32. The R2 forthe single indicator Expertise is .48 showing that Expertise is a
meaningful mediator. The overall R2 for Trust, the dependent
variable,
is
.89,
which
is
considered
strong
however,
the
high
R2 is
likely
an
artifact
of
the
reduced
measurement
model
that
the
constraints of CB-SEM force on the researcher. Table 3 summarizes
the hypotheses tests based on the CB-SEM analysis. Four of the five
hypotheses
are
supported

a
