CASP Checklist: 10 questions to help you make sense of a Systematic Review
How to use this appraisal tool: Three broad issues need to be considered when appraising a
systematic review study:
Are the results of the study valid? (Section A)
What are the results?
(Section B)
Will the results help locally?
(Section C)
The 10 questions on the following pages are designed to help you think about these issues
systematically. The first two questions are screening questions and can be answered quickly.
If the answer to both is “yes”, it is worth proceeding with the remaining questions. There is
some degree of overlap between the questions, you are asked to record a “yes”, “no” or
“can’t tell” to most of the questions. A number of italicised prompts are given after each
question. These are designed to remind you why the question is important. Record your
reasons for your answers in the spaces provided.
About: These checklists were designed to be used as educational pedagogic tools, as part of a
workshop setting, therefore we do not suggest a scoring system. The core CASP checklists
(randomised controlled trial & systematic review) were based on JAMA ‘Users’ guides to the
medical literature 1994 (adapted from Guyatt GH, Sackett DL, and Cook DJ), and piloted with
health care practitioners.
For each new checklist, a group of experts were assembled to develop and pilot the checklist
and the workshop format with which it would be used. Over the years overall adjustments
have been made to the format, but a recent survey of checklist users reiterated that the basic
format continues to be useful and appropriate.

Literature Review Research Matrix
Please note that the first row of data is meant as an example. Please read the example article (Zhang et al., 2023) as a guide for how
to dissect each article assigned.
Keep in Mind:
1). This is not merely an assignment for you to find information in an article and copy and paste information into the columns in the
below matrix. Read and analyze the authors’ work in each article and evaluate it based on the assigned readings for this course and
then offer your evaluation of what you read. You are to offer the content to reflect that you are an informed consumer of research.
2). There is much variation in published primary research articles and reports. Not all authors will include all the same information,
verbatim or at all, based on the headings in the columns below. If that is the case, you will need to offer your own analysis of what
the information should be in a logical manner aligned to the other information in the source that is provided. There should be no blank
cells in the below matrix.
3). Communicate your input in a manner that is completely scholarly, professional, and consistent with the expectations for members
of an identified field of study, using APA style and formatting, with few or no errors and include a formal APA style reference list.

Abstract: The study aimed to examine associations between workplace culture of health and employee work engagement, stress, and depression. Employees (n = 6235) across 16 companies voluntarily completed the Workplace Culture of Health (COH) Scale and provided data including stress,
depression, and biometrics through health risk assessments and screening. We used linear regression
analysis with COH scores as the independent variable to predict work engagement, stress, and depression. We included age, gender, job class, organization, and biometrics as covariates in the models.
The models showed that total COH scores were a significant predictor of employee work engagement
(b = 0.75, p < 0.001), stress (b = −0.08, p < 0.001), and depression (b = 0.08, p < 0.001). Job class was
also a significant predictor of work engagement (b = 2.18, p < 0.001), stress (b = 0.95, p < 0.001), and
depression (b = 1.03, p = 0.02). Gender was a predictor of stress (b = −0.32, p < 0.001). Overall,
findings indicate a strong workplace culture of health is associated with higher work engagement
and lower employee stress and depression independent of individual health status. Measuring
cultural wellbeing supportiveness can help inform implementation plans for companies to improve
the emotional wellbeing of their employees.

1. Introduction
Employee emotional health and wellbeing have become a critical concern for organizations today [1]. A 2021 survey found that 76% of U.S. employees reported at least one
symptom of a mental health condition, with the most common symptoms being burnout,
depressive feelings, and anxious thoughts [2]. Estimates suggest that 28% of US adults
report high stress and approximately 8% experience clinical depression [3,4]. It is likely
these numbers are under representative due to many not seeking or having access to
treatment. Many employers offer workplace health promotion programs to support and
improve the health and wellbeing of their employees [5]. Research has shown that establishing a culture of health in the workplace may help facilitate the effectiveness of health
promotion initiatives [6–8].
Workplace culture of health refers to the influence of the characteristics of the physical
and social environment on behaviors and attitudes related to health and wellbeing in the
workplace [9,10]. The primary constructs of workplace culture of health include leadership,
policies, programs, supervisor support, peer support, and morale. Theories such as the
social-ecological model support the influence of culture as a way to target behavior change.
The social-ecological model posits that individuals’ behaviors and health outcomes are
influenced interactively by individual, interpersonal, community (workplace) and policy
level [11]. In the workplace, interpersonal factors such as coworker relationships and
supervisor role modeling and community factors such as access to healthy food options
or space to be physically active can positively influence employees’ health choices in the
Int. J. Environ. Res. Public Health 2022, 19, 12318. https://doi.org/10.3390/ijerph191912318

workplace [12–14]. In the workplace, socioecological approaches move beyond convincing
individual employees to make healthier choices. It necessitates the organizations to create
an environment that makes choosing healthy behaviors the easy and convenient choice [6].
Many workplace promotion programs address specific individual health-related behaviors
such as smoking cessation or nutrition support [5]. These particular programs, however,
may only apply to a subset of employees. Influencing culture through interpersonal,
community, and policy level factors can reach employees regardless of where they are
in their health journey or their participation in workplace health programs [15]. Further,
employees’ health status can shift quickly and frequently, and having a culture that supports
employees in all stages can also help address these evolving health concerns.
In recent literature, workplace culture of health has been conceptualized and assessed
at both the employer and employee level [16,17]. Employer-level measures are completed
by a single representative typically involved in the wellness initiative. This singular
perspective may not comprehensively assess the organization’s culture. Nevertheless,
positive outcomes have been associated with employer-level health culture. Goetzel and
colleagues observed that companies with a high internal culture of health had greater
appreciation in company stock price when compared to companies with low internal
culture of health [18]. A longitudinal study of 21 employers found that improvement in an
organization’s culture of health predicted improved employee health risks [19].
Employee-level culture of health measures assesses how the organization supports
health and wellbeing from the employee perspective. Previous studies using employee
level culture of health measures observed that culture of health is associated with higher
levels of job satisfaction and retention [15], work engagement [16], and healthy behaviors
such as physical activity and healthy eating [20]. A 2016 on US government employees
(n = 4703) found that workplace culture of health was negatively correlated with anxiety
and depression [21]. Similar results were observed in employees in China, where higher ratings of workplace culture of health were associated with better psychological wellbeing [22].
Domains of workplace culture of health such as leadership and coworkers support have
been found to decrease employee health risk [8] and promote positive health behaviors [20].
However, there is only one U.S.-based study that has examined workplace health culture
and emotional wellbeing from employees’ perspective [21]. Other studies in this area have
measured workplace culture of health from the employer-level, which may not capture a
comprehensive perspective [18,19]. In addition, that study did not use a validated research
tool to measure workplace culture of health, limiting its generalizability [21]. There is a
need to assess workplace health culture using evidence-based measures. It is also unknown
the impact of physical health status on ratings of workplace culture of health and its effect
on emotional wellbeing.
Further, few studies have examined job class and gender differences in regard to the
relationship between workplace culture of health and employee emotional health outcomes.
A study with employees (n = 880) at a Korean life insurance company found that job
classification moderated the relationship between job satisfaction (which was associated
with culture of health), and job retention, where supervisors are more likely to stay in their
current position if they are satisfied with their jobs than non-supervisors. Another study
showed no differences by gender in workplace culture of health scores [23]. However,
research has shown that there are differences in stress [24] and depressive symptoms [25]
by gender, warranting further exploration in this area. Understanding differences in gender
and job class outcomes can help organizations understand the impact of cultural supports
within the complex social arena of workplace environments.
While many studies have examined the relationship between workplace culture of
health and employee health outcomes, few studies have looked specifically at emotional
wellbeing. In addition, existing studies have not taken into account the existing physical
health status of employees in that relationship, and examined the way gender and job class
may play a role in the effects of workplace culture on wellbeing. Further, there is a need for
Int. J. Environ. Res. Public Health 2022, 19, 12318
3 of 13
studies to use a validated metric to assess workplace culture of health from the employee
perspective across organizations.
The purpose of this study was twofold: (1) to determine if there are differences by
gender and job class in workplace culture of health scores, work engagement, stress, and
depression, and (2) to examine associations between workplace culture of health and
work engagement, stress, and depression while controlling for age, gender, job class, and
biometric data in a large sample of working adults in the U.S. We hypothesized that there
would be gender and job class differences by employee health outcome. In addition,
we hypothesized that there would be a positive relationship between workplace health
culture and employee health outcomes, even while controlling of individual level factors.
Results from this study can help inform the design and implementation of emotional health
interventions and show evidence of the benefits of taking a culture of health approach to
workplace wellbeing programs. Further, this research can help understand how communitylevel factors may influence individual outcomes to advance our knowledge of the social
ecological model in the field of workplace health promotion.
2. Methods
2.1. Participants and Data Collection
This study is based on a sample from the Virgin Pulse’s database of workplace culture
of health assessment. The culture assessment was administered via Virgin Pulse online
platform to U.S. based employees of consenting organizations. Eighteen organizations
expressed interest in participating and were given summary reports and wellbeing strategy
recommendations. The organizations were from a variety of industries, including higher
education, health care, real estate, technology, non-profits, financial services, hospitality,
manufacturing, utility, and retail. Each organization helped facilitate employees to take the
assessments using the Virgin Pulse platform and via email. Assessments were launched
between December 2018 and November 2019 and were available to employees for approximately one month during that date range. Employee participation was voluntary. Prior to
completing the survey, all participants were informed and consented to allow the use of the
anonymized data for research. There was a participation rate of 14% across organizations.
Participants in this study took the Workplace Culture of Health Scale and gave permission to use matched data from the employees’ health risk assessment data. Health risk
assessments (HRA) are an instrument used to collect an employee’s health information that
can include biometric data and self-report data, typically provided by an independent 3rd
party through one’s employer. Of the 18 organizations that participated, 16 organizations
also provided HRA data. The final study sample was comprised of 6235 employees across
16 organizations.
2.2. Measures
2.2.1. Workplace Culture of Health (COH) Scale
The Workplace Culture of Health (COH) scale is a 42-item questionnaire designed to
measure employee assessment of how their workplace supports health [10]. Participants
were asked to rate to what extent they agree or disagree with the statements provided.
Responses range from 5 (strongly agree) to 1 (strongly disagree). The scale has been
shown to be reliable and valid [10]. This study used a shortened version of the COH
scale (24 items). Domains measured in the scale include leadership, policies, programs,
supervisor support, coworker support, values, morale, and work engagement. Each
subscale was comprised of two items, with the exception of values that has one item and
morale that has six items. Scores for each domain and for the total scale are calculated
by dividing the total points by the total points possible, then multiplying by 100 to get a
summative index score. In accordance with the scale developers, the engagement domain
is not included in the total score so it can be analyzed as an outcome variable. Previous
research using the full Workplace COH Scale has shown high levels of internal consistency,
with Cronbach alpha coefficients ranging from 0.91–0.97. This is consistent with the
Int. J. Environ. Res. Public Health 2022, 19, 12318
4 of 13
reliability found in this study for the total score, with a Cronbach alpha of 0.92 [10]. The
Cronbach alphas for each subscale were as follows: leadership (α = 0.84), policies (α = 0.67),
programs (α = 0.58), supervisor support (α = 0.85), coworker support (α = 0.69), morale
(α = 0.83), and work engagement (α = 0.81). Job classification was also an item on the
workplace COH scale, where participants were asked to select if they were a “supervisor”,
meaning they had direct reports, or “individual contributor”, indicating they had no direct
reports. Individual contributors are referred to as non-supervisor employees.
2.2.2. Stress
Stress was measured through a single item self-report question, “in the last month,
how do you rate your stress?” Responses ranged from 0 (no stress) to 10 (high stress). This
measure was included with the Workplace COH Scale.
2.2.3. Depression
The Patient Health Questionnaire Anxiety (PHQ-2) is a 2-item measure designed for a
person to self-rate how frequently they experienced depressive symptoms in the past two
weeks [26]. This measure was included in the HRA. The participants were asked to rate
how often they have been bothered by the statements provided in the questionnaire within
the last two weeks. Items on the PHQ-2 include: (1) “little interest or pleasure in doing
things” and (2) feeling down, depressed, or hopeless”. Responses to statements range from
never experiencing symptoms (0) to experiencing them every day (3). Total scores were
calculated by averaging the scores on each item. Individuals who scored 0 to 2 were given a
score of 100, from 3 to 4 were given a score of 50, and 5 and 6 were given a score of 0. Scores
of 50 or below are indicators of major depressive disorder. Higher scores for depression
indicate a lower risk of depression. Previous research has shown this scale has a strong
internal reliability with a Cronbach alpha coefficient of 0.83 [26].
2.2.4. Biometric Screening Data
Validated biometric data was collected through the HRA and included: (1) body mass
index (BMI), (2) blood pressure, (3) non-HDL cholesterol, and (4) glucose. Pulse pressure
was calculated by subtracting diastolic blood pressure from systolic blood pressure. Pulse
pressure was used in the regression models to assist with potential multicollinearity issues
due to the relationship between systolic and diastolic blood pressure.
2.3. Data Analysis
Descriptive statistics including mean and standard deviations were calculated for
each variable for the total sample, by job class, and by gender. To explore the relationships
between COH scores and employee health outcome variables, bivariate correlations, independent sample t-tests, and regression models were performed. Bivariate correlations
were conducted for all continuous variables. A linear regression model was conducted
to determine the extent to which work engagement, stress, and depression were associated with COH scores while controlling for gender, job class, age, biometric data, and
organization. The categories for gender were male and female. The reference group for
gender was female in the regression models. The categories for job class were supervisor
and non-supervisor. Non-supervisor was the reference group in the regression models.
Organization number was included as a categorical variable, and was used to control for
any between group differences. Full results of the model are included in Appendix B. The
assumption of normality was checked using skewness and kurtosis, which was found to be
within normal range for all variables with the exception of depression scores. Multivariate
normality was checked using Q-Q plots and the residuals were found to be normally
distributed. Multicollinearity was checked for each regression model using the variance
inflation factor (VIF). Multicollinearity for each independent variable was tested using
VIF and Tolerance (T) scores. The values of VIF for all independent variables ranged from
1.05–1.4 (0.01), an indication of no

multicollinearity. The assumption of homoscedasticity was checked using plotted residuals
and was found having non-constant variance for the models, therefore, robust standard
errors were used to address the violation [27]. Autocorrelation was checked using ACF
plots and the Durbin-Watson test. The Durbin-Watson test statistics ranged from 1.89–1.94,
indicating the model did not violate the assumption of autocorrelation [28]. Due to the fact
that there were only minor violations of the assumptions of the generalized linear model
and that normal distribution of variables is not an assumption of linear regression, we
proceeded with analyzing the data [29]. Subsequently, standardized regression coefficients
were analyzed to assess the relative importance of each independent variable individually
predicting each dependent variable. In addition, t-tests were run to determine differences
in COH scores and primary outcome variables by gender and by job class. All analysis was
performed using R [30].
3. Results
3.1. Participant Characteristics
Tables 1 and 2 show demographic data and descriptive statistics of each study variable
by gender, and by job class. Approximately 64% of the sample identified as female, and
approximately 19% classified themselves as a supervisor. The average age for the total
sample was 45 years old. Regarding employee perception of workplace culture of health,
scores above 80 on the COH total score indicate a “high” health culture, scores between
79 to 65 indicate a “medium” health culture, and scores below 65 is considered “low” [31].
The average COH score was 73.86, falling in the “medium” score range for workplace
COH. The average stress score was 5.47 out of 10, with over 24% of the sample reporting
a score of 8 or higher. Scores from 1 to 3 indicate low stress, from 4 to 7 moderate stress,
and scores above 8 indicate extreme stress level [4]. Regarding depression, scores on the
PHQ-2 of 50 or below indicate major depression disorder is likely [26]. Our average score
of 96.87 indicated there was little to no average risk of depression in our sample, with
approximately 5% of the sample was at medium to high risk for depression.
