Association of Psychosocial Work Hazards With Depression
and Suboptimal Health in Executive Employees
Sandy Huey-Jen Hsu, PhD, Duan-Rung Chen, PhD, Yawen Cheng, PhD, and Ta-Chen Su, MD, PhD
Objectives: This study aims to investigate whether psychosocial work-
related hazards, measured by workplace justice and employment insecurity,
are associated with depression and suboptimal health status in Taiwan’s
executive-level employees. Methods: There were 365 executives who have
received a series of cardiovascular health examinations, blood sampling, and
self-reported questionnaires, which included the psychosocial work-related
hazards and the CES-D scale. Suboptimal health status was defined as the
presence of dyslipidemia or prediabetes. Results: Executive-level employ-
ees perceived lower workplace justice and higher employment insecurity and
had a significantly higher risk of depression (CES-D scores 16 or 23).
However, workplace justice was identified as a significant determinant
factor that was negative for dyslipidemia but protective for prediabetes.
Conclusion: This study supports the fact that psychosocial work-related
hazards can independently contribute to the risk of developing depression,
prediabetes, and dyslipemia in executives.
A
s a result of globalization, several companies have been forced
to undertake mergers and downsizing in addition to introduc-
ing temporary or contract-based project employees.
1,2
Like all
social transformations, these changes may potentially affect the
health of individuals and general population.
2
Therefore, psycho-
social work hazards have been the focus of a large number of studies
during the past few decades. Recent epidemiological studies have
shown that both employment insecurity and workplace injustice are
important psychosocial hazards of stress-related illness in the work-
place.
3,4
Job insecurity has been defined as an employee’s perception
of a potential threat to the continuity of his or her current position
and the everyday experience involving prolonged uncertainty about
the future.
5
Hence, employment insecurity can be considered as a
work stressor, which has been found to be associated with poor
health and could increase the risks of psychological problems.
3,6
Workplace justice is generally defined as workers being
fairly treated in the workplace.
7
On the basis of previous research,
workplace justice comprises the following components: resources
and benefits distribution (distributive justice), processes and pro-
cedures condition distribution (procedural justice), and interperso-
nal relationships (interactional justice). Prior reports have
demonstrated that a lower level of workplace justice is associated
with various health problems as well as mental disorders.
7,8
The most common model used in prior studies to evaluate the
associations between workplace justice and employee’s health is the
Demand-Control-Support (DCS) model.
7
The DCS model has three
major components to describe the workplace qualities: demands
(psychological), control (or decision latitude), and support (social).
Workplace stress is thought to be the result of a mixture of high
demands, low control, and low social support. Moreover, several studies
have suggested that long work hours, interpersonal conflicts, under-
utilization of skills, inadequate rewards, and organizational problems
are considered to be some of the major sources of job stress.
9,10
Despite the fact that a great deal of previous evidence has
shown that justice perception is associated with a higher risk of
mental distress as well as poor self-rating health status,
11,12
only a
few studies have examined the relation between psychosocial work
hazards and suboptimal health status, such as elevated serum
lipids,
13
prediabetes,
14
and immune system diseases.
6
Furthermore,
most researchers who have investigated the effects of job insecurity
on health have focused on psychological morbidity as an outcome,
often deduced as the only outcome. Few studies have looked at the
effect of job insecurity and workplace justice on physiological
measures. Moreover, there are only a few empirical findings that
simultaneously associate health with both employment insecurity
and workplace justice, primarily in Chinese-speaking working
populations.
15–18
In this study, we extended this line of research
to explore the influences of psychosocial work hazards on both
psychological assessments and suboptimal health status.
Taiwan is a newly industrialized country that has experienced
dramatic industrial transformation and changes over the past dec-
ades. Psychosocial work hazards are a widespread public problem in
most industrialized countries. However, there are few reports of
such studies conducted on working populations in Asia.
19
In
Taiwan, psychosocial work hazards have recently received public
health attention, with one previous study investigating the associ-
ation between psychosocial work hazards and health impacts among
the general population.
19
To our knowledge, socioeconomic dis-
advantaged groups may suffer more from workplace injustice and
uncertainty.
19
Generally speaking, executives tend to have access to
more resources,
20
and perceived more workplace justice and
employment security.
20
However, executives are responsible for
upholding stakeholders’ or owners’ expectations and taking care of
employees, which may increase their work-related stress. Not much
is known regarding the actual health impacts of psychosocial work
hazards on this group.
This study aims to investigate whether psychosocial work
hazards, including employment insecurity and workplace justice,
are associated with depression and physical suboptimal health in
Taiwan’s executive employees. The research modeling outline is
shown in Fig. 1.
MATERIALS AND METHODS
Study Subjects
Between 2009 and 2011, 689 adults in the age group of 35 to
65 years were recruited by a bulletin announcement to participate in
a case–control study of work- and environment-related cardiovas-
cular diseases as the control subjects of acute coronary heart
diseases (CHD) in National Taiwan University Hospital
(NTUH).
21,22
Participants reported they were free from phys-
ician-diagnosed CHD, cerebrovascular disease, and heart failure.
Three hundred sixty-five participants were employed as deputy
