This paper proposes that consideration of future safety consequences (CFSC) would moderate the relationships
between safety training and workers involvement on
healthcare workers (HCWs) safety behaviors (safety compliance and safety participation). Survey data was
obtained among 229 nurses from Abuja secondary health
facilities, Nigeria. SmartPLS 3.0 was applied to test the hypotheses that comprised both the direct effect of safety
training and workers involvement on safety participation and
safety compliance and moderating role of CFSC on these
relationships and consequently bootstrapping was conducted to investigate the standard error of the estimate and t-values.
The findings showed that safety training positively relates to
safety compliance and safety participation and workers involvement positively relates to safety compliance and
participation. Furthermore, CFSC moderates the
relationships between workers involvement and safety compliance. The research provides empirical evidence on the
significance of CFSC as moderator. This contributes to the
utility of Social Exchange Theory (SET) and Construal
Level Theory (CLT). Furthermore, in order to achieve an optimally safe hospital environment, hospital management
should provide employees with safety training and involve
them in the safety activities and consider individual CFSC when making decisions on how to improve hospital safety.

1. INTRODUCTION
Organizational accidents and injuries cause huge amount of employee’s lives
and property damages every year (Zhou & Jiang, 2015). The hidden costs may
range from four to five times the direct costs (Heinrich et al., 1980). Work-related
47
injuries and accidents are the major concern for nurses in various hospitals, given
the risky nature of hospitals environment (Nixon et al., 2015). Nurses frequently
encountered with daily hazards which includes: physical, biological, and chemical
hazards (Nixon et al., 2015). Physical hazards range from environmental conditions
that may resulted to falls, cuts or electrical shocks. Biological hazards on the other
hand, range from exposure to blood-borne pathogens such as HIV/AIDS, bacteria,
hepatitis, and tuberculosis among others as a result of injecting patients, drawing, or
suturing of blood from the patients (Perry, Parker & Jagger, 2003). Chemical
hazards includes nurse’s contact with hazardous agents ranging from carcinogens,
corrosives and toxic (Ford & Wiggins, 2012). According to American Nurses
Association (2011), in the year 2011 alone, 40% of hospitals nurses reported
occupational injuries. In financial term, annual back injuries alone has been
projected to cost 16 billion dollars in medical treatment, worker’s compensation
benefits, employee turnover costs due to injuries (White, 2010). Nigeria is not
immune to these issues (Akinwale & Olusanya, 2015; Aluko et al., 2016; Mashi,
2014). For example, a report from the Federal Capital Territory Administration
(FCTA) reported over 100 HCWs recently suffered from needle stick injuries,
Hepatitis B and HIV/AIDS due to exposure to healthcare waste (Adejoro, 2014). As
Nigeria is aspiring to achieve its Vision 20:2020, the Vision reflects the country to
be among the world leading economy in the year 2020 (National Planning
Commission, 2010), occupational injuries and diseases that may impair productive
citizens deserves special attention.
Due to the high cost of injuries highlighted above, occupational safety
researchers and practitioners have identified the importance of safety training, —
which involves the acquisition of knowledge and skills that improve employee safe
behavior in the hospitals (Vredenburgh, 2002). This construct is regarded as an
important leading indicator of safety (e.g., Beus, McCord & Zohar, 2016; Christian,
Bradley, Wallace & Burke, 2009; McGonagle et al., 2016; Shea et al., 2016;
Sinelnikov, Inouye & Kerper, 2015; Zohar, 2010), and increase employee positive
safety behaviors (Cooper & Phillips, 2004; Neal & Griffin, 2004).
48
Another important leading safety indicator is workers’ involvement in to safety
(Beus et al., 2016; Christian et al., 2009), —which involves the behavior-based
technique which includes employees in an upward information flow and safety
decision process (Vredenburgh, 2002). In safety management literature, there is a
call to incorporate other variables to moderate organizational factors with employee
safety behavior (Christian et al., 2009; Foster & Nichols 2015; Mickey et al., 2015;
Zohar, 2010) due to the inconsistency in the findings (Ismail, Asumeng & Nyarko,
2015; Vinodkumar & Bhasi, 2010). This inconclusiveness in safety literature
concerning these relationships calls for more research to examine possible
moderators to explain these relationships (Baron & Kenny, 1986).
Therefore, to identify possible constructs that can moderate these relationships
is significance to practitioners to use to reduce hospital injuries. This paper
addresses this research gap by investigating an important personality variable
potentially vital that may elicit the relationship between safety training, workers
involvement and healthcare workers safety behavior— consideration of future
safety consequences (CFSC)—which Probst, Graso, Estrada and Gree (2013) define
as the “degree to which employees consider the future versus immediate
consequences of their safety-related behaviors” (p. 125). Specifically, in this paper
we investigate the moderating effects of CFSC on relationships between safety
training, workers involvement and healthcare workers safety behavior (safety
compliance and safety participation) among nurses in Abuja secondary health
facilities in Nigeria.
We argued in this paper that CFSC will moderate these relationships because
of the following reasons: firstly, the extent literature confirmed that consideration of
future consequences (CFC) has an influence on the workers behavior of violating
the organizational rules and procedures (Takemura & Komatsu, 2013). Secondly,
recent empirical study has presented that individual high in CFC reported higher
intentions and sustain volunteerism (helping) others in the organization (Maki,
Dwyer & Snyder, 2016). Therefore, we argued that by integrating these constructs
will provide additional evidence to practitioners on how to improve safety
49
compliance and participation in the organization. Such that, the relationships
between safety training, workers involvement and healthcare workers safety
behavior is expected to be stronger for the healthcare workers high in CFSC than
for those employees who are low in CFSC. In doing so, we advance the general
understanding in safety literature and contributes to safety management research,
and we offer additional information on the functioning of CFSC as an important
variable for hospital managements to use to improve healthcare worker safety.
Hence, the objectives of this study therefore are twofold: to examine the influence
of safety training and workers involvement on healthcare workers safety behavior
and to assess the moderating role of CFSC on the relationships.
2. LITERATURE REVIEW
2.1 SAFETY PERFORMANCE
In extent literature, due to the dearth of measures to assess the effectiveness of
organizational safety programs (Glendon & Litherland, 2001), no agreement is
reached on the actual safety performance components (Fernández-Muñiz et al.,
2007). Historically, to assess safety performance, studies focused on the direct
safety performance outcomes such as employees compensation cost, injuries
frequency among others (Moore & Viscusi, 1989). Nevertheless, these measures
were recognized as a poor measures of safety (Glendon & Mckenna, 1995) because
they were inadequately sensitive, retrospective and in some cases risk exposure is
ignored. These outcomes are occasional and thus, forms a skewed distribution
(Christian et al., 2009). Additionally, the high rates of under-reporting among the
industrial players in Nigeria (Tandberg et al., 1991) has resulted in suggesting that
safety performance outcomes recorded by the hospitals are too unreliable to
understand hospital safety (Cooper, 2000).
Due to the inadequacy of injuries and accident data highlighted above, many
researchers used safety behavior as the dependent variable in an effort to understand
safety performance (Barbaranelli, Petitta & Probst, 2015). Safety behavior “refers to
the employee rational reactions to dangerous external stimuli which conform to
50
safety procedures to achieve the desired security objectives” (Zhang, Li & Zuo,
2015, p. 984). In other words, it is defined as “the safety-related actions or
behaviors that workers exhibit in almost all types of work to promote their safety
and that of others” (Burke & Signal, 2010, p. 3). Beus, McCord and Zohar (2016)
defined safety performance behavior “as any workplace behaviors that affect the
likelihood of physical harm to persons” (p. 3).
Employee safety compliance and participation are the main components of
safety performance behavior used in Griffin and Neal (2000) model that described
the actual behaviors that workers exhibit in the workplace (Griffin & Neal, 2000).
Safety compliance is defined as “generally mandated” behaviors (Neal, Griffin &
Hart, 2000, p. 101) which they drawn from the two main components of general job
performance from the work of Borman and Motowidlo (1993)—task performance
and contextual performance—safety compliance was used as task performance and
therefore refers to the core activities that workers carry out to preserve safety at
work. These behaviors includes following standard work procedures or wearing
personal protective equipment (Neal & Griffin, 2006).
Workers safety participation, on the other hand is defined as behaviors
“frequently voluntary” (Neal, Griffin & Hart, 2000, p. 101). In other words, are
behavior “that may not directly contribute to workplace safety, but that do help to
develop an environment that supports safety” (Griffin & Neal, 2000, p. 349) and
can be associated to safety improvement. These safety behaviors includes
voluntarily participating in safety activities, attending safety meetings, or helping
colleagues with safety-related matters (Neal & Griffin, 2006).
2.2 SAFETY TRAINING
Various antecedents were empirically tested in an effort to understand safety
performance across various work setting. For instance, Hayes, Perander, Smecko,
and Trask (1998) and Lee and Dalal (2016) explored how safety climate and culture
were important in predicting workers safety performance in the organizations.
Additionally, in their model, Griffin & Neal (2000) regarded safety knowledge and
51
safety motivation as proximal factors that have a positive relationship with workers
safety behavior. Safety leadership was also found to have a positive relationship
with workers safety behavior (Smith, Eldridge, & DeJoy, 2016). Other study used
individual characteristics such as personality and age differences (e.g., Siu, Phillips
& Leung, 2003), level of education (Gyekye & Salminen, 2009) among others.
Training is “refers to instruction and practice for acquiring skills and
knowledge of rules, concepts, or attitudes necessary to function effectively in
specified task situations” (Cohen, Colligan, Sinclair, Newman & Schuler, 1998, p.
11). Safety training is an important risk prevention and control strategies to
guarantee every employee is safe in a good workplace conditions (Cohen, 1998).
Safety training is defined as “instruction in hazard recognition and control
measures, learning safe work practices and proper use of personal protective
equipment, and acquiring knowledge of emergency procedures and preventive
actions” (Cohen, 1998, p. 11). Safety training has been recognized as an important
organizational characteristic distinguishing organization with successful safety
program (Zohar, 1980), and is an effective means for employees to enhance their
skills and knowledge of safety in the organizations (Shea et al., 2016).
Literature in occupational safety supports the view that safety training is a key
factor in maintaining and changing workers attitude toward safety (Ali et al., 2009;
Boughaba, Hassane & Roukia, 2014; Donald & Cantre, 1994; Keffane, 2014;
Mearns, Whitaker & Flin, 2003; Vinodkumar & Bhasi, 2010; Zohar, 1980).
Organizations can improve workers safety behavior via keeping them aware of
health and safety practices through seminars, workshops, training on the job among
others (Mearns, Hope, Ford & Tetrick, 2010). Study conducted in the US among the
representatives of 57 projects summited that higher safety performance is attained
with safety training (Hinze, Hallowell & Baud, 2013). Similar studies also found
that companies can transfer safety knowledge through workers orientation, toolbox
talks, and training sessions among others (Hallowell, 2012; Lu & Yang 2011;
Vredenburgh, 2002). In addition, meta-analytic findings show that perceptions of
safety training positively related to safety compliance and participation (Christian et
52
al., 2009). Meta-analysis studies also reported strong empirical evidence of the
effectiveness of safety training on employees’ safety behaviors (Ricci, Chiesi, Bisio,
Panari, & Pelosi, 2016; Robson et al., 2012). Taken together, there are clear
evidence in the literature that workers perception of safety training is significantly
related to workers safety behaviors. Based on the above submission, empirical
evidence suggests that safety training is important in understanding worker’s safety
compliance and participation. Therefore, we hypothesized that:
Hypothesis 1a: Safety training is positively related to safety compliance.
Hypothesis 2a: Safety training is positively related to safety participation.
2.3 WORKERS INVOLVEMENT IN TO SAFETY
Various antecedents were empirically tested in an effort to understand safety
performance across various work setting. For instance, Hayes, Perander, Smecko,
and Trask (1998) and Lee and Dalal (2016) explored how safety climate and culture
were important in predicting workers safety performance in the organizations.
Additionally, in their model, Griffin & Neal (2000) regarded safety knowledge and
safety motivation as proximal factors that have a positive relationship with workers
safety behavior. Safety leadership was also found to have a positive relationship
with workers safety behavior (Smith, Eldridge, & DeJoy, 2016). Other study used
individual characteristics such as personality and age differences (e.g., Siu, Phillips
& Leung, 2003), level of education (Fernández-Muñiz et al., 2009; Gyekye &
Salminen, 2009) among others.
Employee involvement is a vital factor in the organization safety program used
to reduce injuries and accidents (Vinodkumar & Bhasi, 2010). Employee
involvement is the “extent employees could influence and control OHS
management issues at the workplace” (Masso, 2015, p. 64). In other words,
employee’s involvement into safety management process involves upward
communication flow among individuals or groups and decision-making process
within the organization (Vredenburgh, 2000) because employees use to make
suggestions about safety improvements, especially when new technologies and
53
materials were introduced (Butler & Park, 2005). This factor is regarded among the
important indicator of positive organizational safety culture because is the best ways
to achieve safety ownership (Cooper, 1998; Ford & Tetrick, 2011; Liu, Bartram,
Casimir & Leggat, 2014). Employee’s involvement is a fundamental element of
safety management since it help organization to achieve main objectives and goal of
occupational safety and health implementation and improvement in organizational
safety conditions for the benefit of both employees and organizations (Podgórski,
2005).
High employee’s involvement in the organization’s strategic safety decisions
can reduce lost-time frequency rates (LTFR) (Shannon et al., 1996). Employee’s
involvement was examined to lower the frequency of unsafe behavior and injuries
in the organizations (Camuffo, De Stefano & Paolino, 2015; Rooney, 1992). Within
the hospital environment, Garrett and Perry (1996) found that employee’s
involvement in to safety decisions reduced injuries effectively within one year.
Vinodkumar and Bhasi (2010) reported employee involvement significantly related
with safety participation. Keffane and Delhomme (2013) also reported employee
involvement predicts safety compliance in a study aimed to understand the
performance of road safety practices in France. Based on the above submission,
empirical evidence suggests that employee’s involvement is important in
understanding employee’s safety compliance and participation. Therefore, we
hypothesized that:
Hypothesis 1b: Employee’s involvement is positively related to safety compliance.
Hypothesis 2b: Employee’s involvement is positively related to safety
participation.
2.4 CONSIDERATION OF FUTURE SAFETY CONSEQUENCES
Consideration of future consequences (CFC) is an individual differences
variable that explain how individuals differ in the extent to which they consider
distant versus immediate consequences of their potential behaviors. CFC is defined
as “The extent to which people consider the potential distant outcomes of their
54
current behaviors and the extent to which they are influenced by these potential
outcomes” (Strathman, Gleicher, Boninger & Edwards, 1994, p. 743). Relative to
low CFC individuals, individuals high in CFC reported less use of alcohol and
tobacco (Strathman et al., 1994), exercise regularly (Ouellette et al., 2005), less
aggression (Joireman et al., 2003) participate in pro-environmental behavior
(Joireman et al., 2001), high academic performance (Peters, Joireman & Ridgway,
2005) among others. Probst et al. (2013) extended the concept to safety and define
consideration of future safety consequences (CFSC) as the “degree to which
employees consider the future versus immediate consequences of their safety-
related behaviors” (Probst et al., 2013, p. 125) and is related to various safety
outcomes (Probst et al., 2013).
We argue in this paper that consideration of future safety consequences
(CFSC) would provide additional explanation on what boundary condition safety
training and employee involvement can influence safety compliance and
participation. Therefore, the following hypothesis are advanced:
Hypothesis 3a: The positive relationship between safety training and safety
compliance will be stronger when consideration of future safety consequences is
high.
Hypothesis 3b: The positive relationship between workers involvement and safety
compliance will be stronger when consideration of future safety consequences is
high.
Hypothesis 3c: The positive relationship between safety training and safety
participation will be stronger when consideration of future safety consequences is
high.
Hypothesis 3d: The positive relationship between workers involvement and safety
participation will be stronger when consideration of future safety consequences is
high.

2.5 CONCEPTUAL FRAMEWORK AND UNDERLINING THEORIES
This paper conceptualized that safety training and workers involvement which
are the independent variables influence the healthcare workers safety behavior
(safety participation and compliance). Also the CFSC is expected to moderate these
relationships. These relationships are shown in Figure 1 below.
The framework is underpinned by two theories i.e Social Exchange Theory
(SET) (Blau, 1964) and Construal Level Theory (CLT) (Liberman & Trope, 1998).
The SET “is one of the most influential conceptual paradigms for understanding
workplace behavior” (Cropanzano & Mitchell, 2005, P. 874). The primary tenets of
this theory is the reciprocity of commitments between employees and employer
over time (Blau, 1964). When an organizations exhibits a readiness to make
workplace safe and healthy, the employee oblige by engaging in desirable behavior
such as high compliance with work procedures and reducing undesirable behavior
such as unsafe behavior. In this paper, SET is theoretically applied to explain the
direct relationships between safety training, workers involvement and healthcare
workers safety behavior (Neal & Griffin, 2006). When hospital cares for their
workers safety (i.e., the hospitals give workers training and involve them in to
safety decision processes), the workers are likely to develop tacit obligations to
perform their duties, using behavior beneficial to the hospitals. When hospital
management offers adequate training to the workers, the HCWs would accordingly
carried out their responsibilities efficiently and safely, which then results in better
safety performance.
On the other hand, Construal Level Theory (CLT) (Liberman & Trope, 1998)
posits that employees have distinctive psychological links with events and objects
grounded on perceived social and temporal distances, taking along a remarkable
wrinkle to the discussion of individual safety behavior. According to this theory,
people construe distant future events using abstract representations. In contrast,
people who choose their behavior thinking only about immediate events using
concrete term (Trope & Liberman, 2010). This theory (Liberman & Trope, 1998) is
widely used in an effort to understand individual’s decision over time in the area of
56
psychology (e.g., Fujita, & Sasota, 2011). Drawing from CLT (Trope & Liberman,
2010), this paper identify CFSC as plausible moderator that permit further
examination of safety training, workers involvement and safety behavior
relationships. Drawing from CLT theory, the study proposes that CFSC can play an
important role theoretically in explaining the moderating effects of CFSC on safety
training, workers involvement and safety behavior in that healthcare workers
framed their safety behavior in two different ways (i.e high-level vs. low-level
construal) (Liberman & Trope, 1998). Those with low-level construal frame their
safety behavior after immediate consideration (low-CFSC workers) while
healthcare workers with high-level construal is expected to frame their safety
behavior weighing at the future considerations.

3. METHODOLOGY
3.1 SAMPLE AND DATA COLLECTION
The research methodology employed in this study was quantitative research
method using questionnaires to test the conceptual model. The study covered 12
secondary health facilities with total population of 1063 nurses and the required
samples sizes is 278 based on Krejcie and Morgan (1970) table of sample
determination. Four health facilities were randomly selected using cluster sampling
technique (the type of probability sampling) using the recommendation of Gay and
57
Diehl (1992) five steps technique of selecting clusters with the total number of 317
nurses. Therefore, all the 317 nurses in these four facilities were responded to the
questionnaire. Of the 317 questionnaire distributed, 229 valid questionnaires were
returned and used which make the response rate of 72%. The 229 response is
enough for this study going by the G*power requirement, the minimum sample size
of 153 is required. Since the model had a 3 predictors and 4 interactions, we set the
effect size as medium (0.15) and required power of 0.95. The data was collected by
the researcher and the assistance of two research assistance. This study was
approved by the health and human services of the FCT. A cover letter was attached
to the questionnaire informing the nurses of the study goal. Respondents were
informed that participation was voluntary and that anonymity was guaranteed.
3.2 DATA ANALYSIS TECHNIQUE
The study employed Partial Least Square Structural Equation Modeling (PLS
SEM) SmartPLS 3.0 software (Ringle et al., 2015) to compute both the
measurement and structural models (Anderson & Gerbing, 1988). The rationales for
using PLS are: PLS path models are estimate with a small sample and with non-
normal data (Haenlein & Kaplan, 2004). PLS has the likelihood of providing
accurate computations of moderating effect because its accounts for error (Helm,
Eggert & Garnefeld, 2010). The two-step technique as recommended by Anderson
and Gerbing (1988) and suggestion of Hair et al. (2011), the bootstrapping
technique (5000 resample) was also used to ascertain the significance levels for the
path coefficient.
3.3 MEASURES
Six items adapted from Vinodkumar and Bhasi (2010) were used to measure
safety training. Internal consistency reliability of the items was 0.82. Sample items
include: “Newly recruits are trained adequately to learn safety rules and
procedures” and “safety training given to me is adequate to enable me to assess
hazards in the workplace”. Four items adapted from Vinodkumar and Bhasi (2010)
58
were used to measure employee involvement. The internal consistency reliability of
the items was 0.69. Sample items include: “Management always welcomes opinions
from employees before making final decisions on safety-related matters”, and “my
company has safety committees consisting of representatives of management and
employees”.
Four items adopted from Neal and Griffin (2000) were used to measure safety
compliance. The items reported internal consistency reliability of 0.94. Sample
items include: “I carry out my work in a safe manner” and “I use all the necessary
safety equipment to do my job”. Four items adopted from Neal and Griffin (2000)
were used to measure safety participation. The items reported internal consistency
reliability of 0.89. Sample items include: “I promote the safety program within the
organization” and “I voluntarily carry out tasks or activities that help to improve
workplace safety”. Six items adapted from Probst et al. (2013) were used to
measure CFSC. The items reported internal consistency reliability of 0.71. Sample
items include: “Even though accidents reporting can take a lot of time and effort, it
helps other workers in the future” and “I sometimes need to compromise safety in
order to meet service delivery”. All the items in this section were measured using
five-point Likert scale ranging from 1= strongly disagree to 5= strongly agree.
4. RESULTS AND ANALYSIS
4.1 RESPONDENTS’ PROFILE
Based on the demographics characteristics of the respondents, majority of the
respondents are females 157(68.6%) while male consisted of 72 (31.4 %). Majority
of the respondents were of Hausa ethnic group 59 (29.8%), followed by Yoruba
ethnic group 51 (22.3%). Majority of the respondents are nursing 11 in term of
designation. Majority of the respondents are married 169 (73.8%). Also majority of
the respondents have nursing certificates 142(62%). The mean age and standard
deviation of the respondents were (M=14.67 SD=9.82). The respondents’ mean
years of experience and standard deviation as healthcare worker were (M=14.67
59
SD=9.82). The respondents mean organizational tenure and standard deviation were
(M=4.67 SD=2.31).
4.2 DESCRIPTIVE STATISTICS
Table 1 presents the descriptive statistics, including the constructs means and
standard deviations and the reliability of the variables for descriptive purposes. As
presented in Table 1 the mean value of all the constructs ranged between 3.198 and
4.138. Composite reliabilities also ranged between 0.835 and 0.921 demonstrating
high reliability for all the variables in this study (Hair et al., 2014). Similarly,
Cronbach's Alpha value also ranged between 0.705 and 0.880 demonstrating high
reliability for all the variables (Hair et al., 2014).

4.3 COMMON METHOD VARIANCE
Common method variance (CMV) in a study occur when two or more self-
reported measures are acquired from the same respondents at the same point of
time, the relationship between the constructs may be influenced by CMV(Podsakoff
et al., 2003). This type of variance is attributed to the measurement method rather
than the constructs. In this study, CMV was assessed (Podsakoff et al., 2003) using
Harman’s (1976) one-factor test principle component factor analysis. The rotation
shows that common method bias is not an issue in this study. No single factor
accounted for more than 50% of the variance (Podsakoff et al., 2003). The first
factor accounted for 31.7 percent of the variance.

4.4 MEASUREMENT MODEL EVALUATION
To evaluate the measurement model in this paper, two types of validity were
assessed. Firstly, we assessed the convergent validity and secondly, discriminant
validity was assessed. Convergent validity is determined by examining the
composite reliability, loadings and average variance extracted (AVE) (Gholami et
al., 2013). As reported from Table 2 below, each construct has achieved the
loadings above 0.7, Composite reliability (CR) of all the constructs were all higher
than 0.7 and Average variance extracted (AVE) is above 0.5 as recommended by
Hair et al. (2014) (see Table 3).

WKI4 0.881
Note: AVE = average variance extracted CR= Composite reliability
The discriminant validity (the extent to which items measure distinct concepts) was
assessed following the Fornell and Larcker (1981) criterion by comparing the
61
square root of the AVE with the correlations among constructs (see Table 3). As
shown from Table 3, the square root of the AVEs (values in bolded) on the
diagonals were greater than the corresponding row and column values indicating the
measures were discriminant.

In addition to Fornell and Larcker (1981) criterion, the HTMT ratio was examined
as this criterion is regarded to be a more reliable criterion for evaluating
discriminant validity than the Fornell–Larcker criterion (Henseler et al. 2014;
Henseler, Ringle, & Sarstedt, 2015). The HTMT criterion in this study shows that
discriminant validity is achieved. The highest correlation found is between safety

4.5 STRUCTURAL MODEL EVALUATION
Since the measurement model above is achieved in term of reliability and
validity, we evaluated the structural model to assess the hypothesized relationships
among the variable in this study (Hair et al., 2014). As presented in Table 4 and
Figure 2 below, we evaluated the standardize beta values and the t-values (Hair et
al., 2014). The t-values were obtain using bootstrapping procedure with 5000
resamples. In addition, we also calculated the predictive relevance (Q2) of the model
and effect sizes of each predictors on the dependent variables (f2) (Hair et al., 2014).
Figure 2 and Table 4 show the estimates for the full structural model, which
includes moderator variable (i.e., CFSC) in this study. All relationships in this study
are represented by standardized beta values. Additionally, in testing the
relationships of the structural model, the significance level was set at p<.001,
p<0.05 and p<.01 (1-tailed) (Hair et al., 2014). Significantly, the findings from
Table 4 demonstrated that among the two predictors of safety compliance, safety
training has the highest significant standardized beta coefficient (β=0.408), which
indicates that safety training is the most significant construct in predicting safety
compliance among nurses in Abuja secondary health facilities, Nigeria. Similarly,
among the two predictors of safety participation, safety training has the highest
significant standardized beta coefficient (β=0.301), which indicates that safety
training is the most significant construct in predicting both safety participation and
compliance in this study.

4.6 INTERACTION EFFECT
As presented in Figure 3, Hypothesis 3b stated that CFSC moderates the
relationship between workers involvement and safety compliance. Specifically, this
relationship is stronger (i.e. more positive) for individuals with high CFSC than
individuals with low CFSC. As expected, the finding from Table 5 and Figure 2
showed that the interaction terms representing worker involvement*CFSC on safety
compliance (β = 0.159, t = 1.725, p < 0.05) was statistically significant. Therefore,
Hypothesis 3b was supported. As recommended by Dawson (2013) using two-way
interaction with continuous moderator, the result of the path coefficients (β) was
used to plot this relationship. Figure 3 indicated that the relationship between
worker involvement and safety compliance is stronger (i.e. more positive) for
individuals with high CFSC than individuals with low CFSC.

4.7 IMPORTANCE-PERFORMANCE MATRIX ANALYSIS (IPMA)
To extend the findings in this study, the post-hoc importance-performance
matrix analysis (IPMA) (Hair et al., 2014) was conducted using safety compliance
and safety participation as outcome variables. Figure 4 and 5 visualize the
performance level of each independent variable along with its importance on the
dependent variable so that decisions can be easily made by hospital management
from the graphical representation. The total effect, which draws on path coefficients
(on a scale from zero to 0.4 on the horizontal axis), shows the importance of the
independent variables, while the mean value of their scores (on a scale from zero to
100 on vertical axis) show their performance. From the Figure 4 it becomes obvious
that in relations to assigning priority by hospital management, the variable safety
training is highly relevant for increasing nurses’ safety compliance as its shows the
highest impact. Therefore, hospital management should focus and retain this area of
performance, or even expand the area. From the Figure 5 it becomes obvious that in
relations to assigning priority by hospital management, the variables safety training
and CFSC are highly relevant for increasing nurses’ safety participation due to their
main impact. Therefore, hospital management should focused and retain these areas
of performance, or even expand the areas to ensure nurses safety participation.

5. DISCUSSION
The paper examined the moderating role of CFSC on the relationship between
safety training, workers involvement and healthcare workers safety behavior in
Nigeria. As presented in Table 5 above, The finding indicated that a positive
relationship exists between safety training and safety compliance of nurses in Abuja
secondary health facilities Nigerian (β=0.408; t =5.138; p = 0.000), thereby
supporting H1a. This finding is consistent with previous research (Lu & Yang 2011;
Vinodkumar & Bhasi, 2010; Vredenburgh, 2002). Additionally, the study found a
significant positive relationship between safety training and safety participation
66
(β=0.301; t=3.913; p=0.000) revealing H2a is also supported. The finding is in line
with prior studies (Donald & Cantre, 1994).This findings shows that the Abuja
secondary hospitals in Nigeria have a supportive climate for safety training and that
nurses are transferring the safety training they learned from the various safety
training program implemented by the hospital management to their jobs. This
findings is not surprising given that the study was conducted immediately after the
country suffered from Ebola epidemics, many nurses may have undergone rigorous
emergency response safety training.
The findings also revealed a significant positive relationship between workers
involvement and safety compliance among nurses in Abuja secondary health
facilities (β=-0.402; t =4.721; p = 0.000). Hence, H1b is also supported. The finding
of H1b is congruent with prior research (Camuffo, De Stefano & Paolino, 2015).
The finding also indicated that a positive relationship exists between workers
involvement and safety participation of nurses in Abuja secondary health facilities
Nigerian (β=0.125; t =1.624; p = 0.052), thereby supporting H2b. The finding is in
line with prior studies (Ford & Tetrick, 2011; Liu, Bartram, Casimir & Leggat,
2014). The possible reasons for obtaining these results in Abuja secondary health
facilities is that Abuja is the federal capital of Nigeria where majority of the NGOs
are located. These NGOs always encourages management to involve workers in
safety decisions and allow them to take part in all matters related to safety and
health through their representatives especially on protection measures.
The moderating findings revealed that CFSC moderates the relationship
between workers involvement and safety compliance (β = 0.159; t = 1.725; p =
0.043), hence H3b is accepted. This is in line with our postulation that the
relationship will be stronger for individuals high in CFSC than the individual with
low CFSC as reported in Fig. 3. The finding of H3b is pioneering in safety literature
and our major contribution in this area. The moderation result also shows that CFSC
did not moderates the relationship between workers involvement and safety
participation (β = -0.080; t = 0.680; p = 0.247), hence, H3d is not supported.
Additionally, CFSC fails to moderate the relationship between safety training and
67
safety compliance (β =-0.027; t =0.305, p = 0.380) thereby rejecting H3a. Likewise,
CFSC fails to moderates the relationship between safety training and safety
participation (β =0.112; t =0.700, p = 0.242). The plausible reasons for these results
is that the study population is new to this type of research, and the items are not
tested to non-western culture, also safety research in Africa is still at embryonic
stage (Salminen & Seo, 2015).
Another criteria for evaluating the structural model is coefficient of
determination (R²).The R² of the safety compliance is 0.565 which implied that
safety training, employee involvement and CFSC collectively explained 56.5% of
the variations in safety compliance among nurses in Abuja secondary health
facilities, Nigeria. Additionally, R² of safety participation is 0.221 which implied
that safety training, employee involvement and CFSC collectively explained 22.1%
of the variations in safety participation among nurses in Abuja secondary health
facilities, Nigeria. Chin (1998) classified R² of 0.19, 0.33 and 0.67 as weak,
moderate and substantial respectively. Therefore, the R² values in this study can be
classified as moderate. Other criterion for assessing a structural model is effect-size
(f²) which indicates the effect of particular exogenous latent variable on endogenous
variable. Cohen (1988) classified effect-size of 0.02, 0.15 and 0.35 as small,
medium, large respectively. The effect sizes (f²) of the safety training and workers
involvement on safety compliance were 0.220 and 0.221 which are all medium.
The effect sizes (f²) of safety training and workers involvement on safety
participation are 0.079 and 0.008 which are small effect and no effect respectively.
The effect-size (f²) of the moderator are 0.031 on compliance and 0.028 on
participation which are small respectively. The final evaluating criterion is
predictive relevance (Q²) which is assessed using construct-cross validated
redundancy. Therefore, Q² greater than zero indicates predictive relevance of a
model (Geisser, 1974). Q² of safety compliance is 0.34 and for safety participation
is 0.112 which are all greater than zero, which indicates the model of this study has
predictive relevance.
68
To extend the findings in the study, the post-hoc importance-performance
matrix analysis (IPMA) (Hair et al., 2014) was conducted using safety compliance
and safety participation as outcome variables. Based on Figure 4, it can be observed
that safety training and workers involvement are very significant factors in
determining nurses safety compliance in Abuja secondary health facilities. Based on
Figure 4, it can be observed that safety training and CFSC are very significant
factors in determining nurse’s safety participation in Abuja secondary health
facilities. Therefore, there is need for the hospital management to focus more on
safety training and workers involvement to ensure safety compliance. Similarly,
safety training and CFSC need to be given proper attention to ensure nurses safety
participation.
Early empirical studies (e.g., Hayes et al., 1998) have demonstrated that
employee positive perceptions of safety are linked with fewer incidents and accident
rates. Two management practices examined in this study contribute to the
healthcare workers perception of how strong safety management practices influence
their safety compliance and participation which have the likelihood of fewer
injuries. Healthcare workers safety training and workers involvement in this study
were significant predictors of safety compliance and participation. This should be
given emphasis in developing proper safety program in the hospitals. The findings
similarly show that CFSC is an important variable in HCWs safety behaviors. This
suggests that high CFSC individual would likely to demonstrate high safe behavior.
HCWs who have high CFSC are motivated to regulate their behaviors, to partake in
safety related matters. This findings suggests that CFSC is significant construct to
put into consideration when training HCWs in the hospitals.
Significantly, this paper showed that CFSC interacts with the effect of worker
involvement on HCWs safety compliance. An interesting results is that CFSC
significantly moderates relationship between worker involvement and HCWs safety
compliance. This indicates safety compliance increase for HCWs when worker
involvement is high and CFSC is high. Specifically, worker involvement leads to
higher safety compliance behavior when CFSC is higher rather than low (see Fig.
69
3). This suggests that hospitals where worker involvement is high and workers with
increased CFSC, safety compliance can be improved.
6. THEORETICAL AND PRACTICAL IMPLICATIONS
This findings in this study is significant to both theory and practice.
Theoretically, understanding safety training and employee participation practices
might provide evidence-based promotion of safety management practices in
hospitals and implementation of its philosophy. The study also reported the
predictive power of CFSC in understanding healthcare workers safety behavior. Our
study also tested the utility of social exchange theory (SET) (Blau, 1964) and
construal level theory (CLT) (Liberman & Trope, 1998) in safety context. To the
best of our knowledge this study is pioneering in using Construal Level Theory
(CLT) in safety context.
From practical perspectives, since findings suggest that the safety training play
an important role in employee safety compliance. Therefore, one can believe that a
committed implementation of safety training by all hospital stakeholders is likely to
provide useful changes in HCWs safety compliance. This possibly will present a
benefit for hospitals by maintaining a healthier status in the hospitals and improving
their morale. To the management, it will reduce compensation cost, lower employee
turn-over, reduce insurance premium, reduce lost time and provide efficient and
motivated workers and consequently, improved hospitals productivity. This
empirical findings also provides evidence to practitioners on possible weaknesses in
their safety training practices for safety improvement. We found that when safety
training is high, healthcare workers safety compliance can be increase. Hence, to
improve HCWs safety compliance and decrease hospitals injury incidents, safety
training should be given major attention. This findings is consistent with findings in
the chemical industry in the study of Vinodkumar and Bhasi (2010). The findings
have significant implications for management practice in hospitals, particularly
where HCWs safety is a major concern. The main implication of this paper is that
even though safety training and employee involvement are critical for keeping
70
employees safe, hospital management also need to consider individual CFSC issues
that may provide additional guide. We found initial evidence that CFSC is critical
for enhancing the positive effects of worker involvement and safety behavior.
Consequently, hospital managers and unit managers should consider the role of
CFSC when developing techniques to effectively promote safety compliance of
workers.
7. LIMITATION AND RECOMMENDATIONS FOR FUTURE RESEARCH
Generally, this research contributed to the safety literature on the utility of
CFSC by relating it directly to the hospital environment, which has not been
investigated in hospital setting before and significant of SMPs in understanding
nurses safety performance in African context. As in every empirical study, the
findings of this study is not without limitations. Therefore, while interpreting the
results, the following limitations can be taking into account. Firstly, only one
moderating hypothesis is supported in this study. Therefore, there is need to further
explore these model with the original consideration of future consequences (CFC)
scale developed by Strathman et al. (1994), as Strathman et al. conceptualized CFC
as a general individual differences variable that would be stable across many
settings. Therefore, future research is recommended to use Strathman et al. scale to
investigate the moderating effect of CFC on relationships between safety training
and workers involvement on healthcare workers safety behavior across various
hospitals.
Secondly, this study adopted a cross-sectional research design. Hence, no
causal inferences could be made to the population, such a statement of causal
inferences requires the collection of longitudinal data. Therefore, future studies are
recommended to use longitudinal design to detect variations over time. Finally, in
this study safety compliance and safety participation were assessed using self-report
measures which may be associated with social desirability bias (Grimm, 2010).
There is possibility that the respondents might have over-reported their safety
compliance and safety participation on the survey questionnaires. Thus, future
71
studies may use other method to assess safety compliance and safety participation.
More specifically, supervisor ratings of safety compliance and participation and/or
peers reporting of safety compliance and participation to control for the social
desirability bias.
8. CONCLUSION
The study examines the direct effect of safety training and workers
involvement on healthcare workers safety behavior (safety compliance and safety
participation). The study also examined the moderating effect of CFSC on the
relationship between safety training and workers involvement on healthcare workers
safety compliance and safety participation. The findings revealed that safety
training is positively related to safety compliance and safety participation. It also
revealed that workers involvement is positively related to safety compliance and
participation. CFSC moderates the relationship between workers involvement and
safety compliance. However, the moderating effect of CFSC on the relationship
between safety training and safety compliance had not been established, moderating
effect of CFSC on the relationship between safety training and safety participation
and the moderating effect of CFSC on the relationship between workers
involvement and safety participation had not been established in this study. Thus,
the study recommends future research to explore CFSC as a moderator in other
contexts.
