Abstract and Figures

A meta-analysis of 79 studies reporting cross-sectional and longitudinal relationships between physical symptoms and various occupational stressors was conducted. Stressors were organizational constraints, interpersonal conflict, role conflict, role ambiguity, workload, work hours, and lack of control. The relationships between stressors and eight physical symptoms were quantitatively summarized and contrasted, for both individual symptoms and composite symptom scales. All of the occupational stressors were significantly related to physical symptoms in cross-sectional analyses, and the effect sizes of these relationships varied both by the stressor and the individual symptom examined. The longitudinal relationships were similar to the cross-sectional results, and provided some evidence of temporal consistency of the occupational stressorphysical symptom relationship. Organizational constraints and interpersonal conflict had the strongest relationships with symptoms in both the cross-sectional and longitudinal analyses. Gastrointestinal problems and sleep disturbances were significantly related to more stressors than other symptoms examined. These findings show that it is important to examine physical symptoms, as they are related to a wide range of job stressors and these relationships prevail over time. Potential underlying mechanisms, including the immediacy of physiological reactions to stressors, participants' attributions concerning stressor-physical symptom relationships, and the possible multidimensional nature of symptoms, are proposed and discussed.

A meta-analysis of 79 studies reporting cross-sectional and longitudinal relationships between
physical symptoms and various occupational stressors was conducted. Stressors were
organizational constraints, interpersonal conflict, role conflict, role ambiguity, workload,
work hours, and lack of control. The relationships between stressors and eight physical
symptoms were quantitatively summarized and contrasted, for both individual symptoms and
composite symptom scales. All of the occupational stressors were significantly related to
physical symptoms in cross-sectional analyses, and the effect sizes of these relationships varied
both by the stressor and the individual symptom examined. The longitudinal relationships
were similar to the cross-sectional results, and provided some evidence of temporal consistency
of the occupational stressorphysical symptom relationship. Organizational constraints and
interpersonal conflict had the strongest relationships with symptoms in both the cross-
sectional and longitudinal analyses. Gastrointestinal problems and sleep disturbances were
significantly related to more stressors than other symptoms examined. These findings show
that it is important to examine physical symptoms, as they are related to a wide range of job
stressors and these relationships prevail over time. Potential underlying mechanisms, including
the immediacy of physiological reactions to stressors, participants’ attributions concerning
stressorphysical symptom relationships, and the possible multidimensional nature of
symptoms, are proposed and discussed.

Introduction
Employee health and well-being have gained increasing societal attention, driven by
both rising worker compensation claims and the considerable personal, organiza-
tional, and medical costs associated with stress-related illness (Smith, Karsh,
Carayon, & Conway, 2003). For example, the annual costs of employee stress,
including costs for missed wages due to absenteeism and reduced productivity and
health care costs, have been estimated to be $200350 billion in the United States,
$64.866.1 billion in the United Kingdom, and $232 billion in Japan (Miree, 2007).

Researchers have conducted a great deal of research using a variety of health
indicators, but few quantitative reviews are available that integrate this literature. A
notable exception is Spector and Jex (1998), who conducted a small-scale (2 to 8
studies across variables) meta-analysis in order to provide validation evidence for
their physical symptoms scale by showing positive relationships of symptoms with
role ambiguity, role conflict, and weekly working hours, and a negative relationship
with job autonomy. However, this meta-analysis had limitations: it was confined to a
few stressors, included only studies using the authorsown symptom scale, looked
only at an overall symptom score, analysed a small number of studies, and only
investigated cross-sectional designs. Although those finding are certainly suggestive,
it is important to see whether they hold for specific symptoms, across diverse
indictors of physical symptoms, and in longitudinal designs that enable more
confident conclusions to be drawn about possible antecedents of symptoms.
The present meta-analysis addresses this gap in the literature by presenting a
large-scale review of the association between specific health complaints and various
indicators of job stress in both cross-sectional and longitudinal designs.
While most studies report results for composite symptom scores, it is important
to look at individual symptoms to see if they each relate to stressors in a similar way.
For example, does the perception of organizational constraints relate similarly to a
variety of symptoms, or does it relate more to headaches than to eye strains or
stomach distress? Darr and Johns (2008), looking at individual symptoms, found
that absenteeism had a stronger relationship with fatigue (r.32) than a composite
of other physical symptoms (r.17). These findings underscore the need to examine
the relationships between stressors and individual symptoms in addition to
composite scores. We believe that this study makes an important contribution to
the literature in that it is probably the first review to address the unique relationships
between specific symptoms and various job stressors.
Stress and physical symptoms
There are several theoretical models that attempt to explain the occupational
stressorstrain relationship, and many of them contain similar variables and
elements (e.g., French & Raven, 1962; Frese & Zapf, 1988; Spector, 1988). The
process that underlies such theoretical frameworks posits a stimulus-response process
in which job stressors (aspects of the work environment) lead to strains (psycholo-
gical, physical, and behavioural reactions), mediated by perceptions of the
environment. Emotional responses, such as anxiety or frustration, are often the
most immediate psychological strain responses that are associated with physiological
changes in the body (Spector, 1988).
The neurochemical responses of the body to stress have been examined
extensively, and while there remain many interactions between these neurochemicals
and the body that need further investigation, the major components of the process
are believed to be well identified and understood. Current research suggests that the
hypothalamic-pituitary-adrenocortical (HPA) axis and the sympathetic-adrenome-
dullary (SAM) systems are heavily involved in the relationship between stressors and
health (Dienstbier, 1989; Frankenhaeuser, 1991; Taylor, 1999). When an employee
encounters an event that is evaluated as harmful or threatening, the hypothalamus is
activated and reacts in two ways. First, it activates the HPA system, which is best

understood through the three stages of the general adaptation syndrome: alarm,
resistance, and exhaustion (Selye, 1936, 1976). During this process, the hypothalamus
releases corticotrophin-releasing factor (CRF) into the nervous system. CRF, in
turn, stimulates the pituitary gland, causing it to secrete growth hormone, prolactin,
and adrenocorticotropic hormone (ACTH). ACTH affects the adrenal cortex, which
releases corticosteroids. Corticosteroids help the body return to a neutral state after
reacting to a stressor. Enzymes that act on opioid receptors, such as beta-endorphin
and enkephalin, are also released during the HPA system response to a stressor. They
are associated with immune system disruption (Cohen, Kessler, & Gordon, 1995).
When the hypothalamus is activated, it in turn activates the SAM system by
setting off one of the earliest responses to stress through the sympathetic nervous
system, a reaction that is commonly referred to as the fight-or-flight response
(Cannon, 1932). The activation of the sympathetic arousal in turn stimulates the
adrenal medulla, which secretes catecholamines, specifically epinephrine and
norepinephrine. The secretion of these hormones leads to increased pulse rate,
increased blood pressure, and sweating, among other physiological reactions. Over
time such reactions can result in the experience of physical symptoms, such as
stomach distress, headache, backache, and other musculoskeletal pain. We will next
discuss specific mechanisms leading to such individual symptoms.
Individual symptoms
Our meta-analysis will summarize the findings regarding eight types of individual
symptom: Backache, headache, eyestrain, sleep disturbance, dizziness, fatigue,
appetite, and gastrointestinal problems. We chose these symptoms because they
have been found to be associated with stress and because for each one there was a
sufficient number of cross-sectional studies available for a meta-analysis to be
conducted (k]5).
Backache. Musculoskeletal pains that originate in the upper back, lower back,
shoulders, and neck generally fall into the overarching category of backache. It has
been shown that tenderness in muscles and soft tissues such as tendons and ligaments
are markedly influenced by the impact of daily stressors (Manne & Zautra, 1989;
Zautra et al., 1998). A longitudinal study in individuals with the chronic
musculoskeletal pain diseases, specifically Fibromyalgia and arthritis, found that
exposure to stressors and negative mood over one week was related to increased
reports of pain intensity over the ensuing weeks (Davis, Zautra, & Reich, 2001;
Zautra, Johnson, & Davis, 2005). This relationship between stressors and muscu-
loskeletal pain is believed to arise from the low cortisol and elevated prolactin levels
present during times of stress, which may increase overall pain sensitivity by down-
regulation of the immune system and increased inflammation (Huyser & Parker,
1999; McLean et al., 2005; McLean et al., 2006).
Headache. Headache is pain experienced in the upper half and back of the head,
arising from a variety of mechanisms. Tension-type headaches in particular are
associated with exposure to stressors. The mechanism underlying such a headache is
likely multifactorial and mostly neurological in nature (Spierings, Ranke, &
Work & Stress 3

Honkoop, 2001). It is widely believed that pain-signalling pathways in the brain can
become overly sensitive to painful stimuli when stress is experienced (Bendtsen,
2003). Once the brain is overly sensitive to pain, even the slightest twinge may
increase nerve excitability and be translated into pain signals, leading to the increased
experience of headaches. This heightened nerve sensitivity leads to increased muscle
activity, which facilitates muscular tension, thus leading to the co-occurrence of
stress-induced back and body aches with headaches.
Eye strain. Eye strain, or asthenopia, refers to itchy, sore, or heavy eyes, as well as
blurred or double vision. Eye strains are considered one of several types of
musculoskeletal disorder (MSD) originating from muscular tension associated with
occupational stressors (Gura, 2002). As with backaches and headaches, an
individuals response to occupational stressors produces a biochemical reaction
that promotes inflammation and increases sensitivity to pain sensation in and around
the eyes. Furthermore, workplace activities such as using a computer or performing
visually intense tasks promote the muscles of the inner eye to tighten and fatigue.
These effects combine with a heightened sensitivity to pain and are cumulative.
Sleep disturbance. Work-related stress is the most frequently reported cause of sleep-
related difficulties (Ertel, Karestan, & Berkman, 2008; Rau, Georgiades, Fredrikson,
Lemne, & de Faire, 2001; Roth & Ancoli-Israel, 1999) and 10% to 40% of the
working-age population (2060 years) in Sweden reported that they experienced
difficulty sleeping (Linton & Bryngelsson, 2000). Sleep difficulties are negatively
related to workplace productivity and positively related to the use of physical and
psychological health services and sick leave (Chevalier, Souques, Coing, Dab, &
Lambrozo, 1999; Jacquinet-Salord, Lang, Fouriaud, Nicoulet, & Bingham, 1993;
Stoller, 1994). In a self-report study, work demands were positively related to the
development and chronicity of sleeping problems (Jansson & Linton, 2006). Some
theories emphasize that blood ACTH and cortisol concentrations are increased in
response to acute stress by the release of corticotropin-releasing hormone (CRH)
from the hypothalamic-pituitary-adrenal axis (Aguilera, 1994). These hormones have
been shown to consequently reduce surges in night-time melatonin levels, which may
provoke insomnia and sleep disturbance.
Dizziness. The stress process can lead to feelings of dizziness or light-headedness for
some individuals. The primary mechanisms for this reaction are through changes in
metabolic rate, such as blood pressure and heart rate that are associated with
stressors (Sparacino, 1982). Dizziness may also be related to hyperventilation.
An increase in breathing rate mediated by the sympathetic nervous system during a
stressful time, even if it is minute, can alter the chemistry including the acid/base
levels in the body. This in turn may disrupt neural responses to balance and
coordination through the cerebellum and eighth nerve, which control balance. It has
been shown that nonspecific dizziness due to hyperventilation gradually increases
over several minutes and eventually resolves once the stressor is removed.
Fatigue. Fatigue, a feeling of lack of energy or tiredness, is one of the most common
symptoms reported by individuals who experience stressful situations (Dittner,
Wessely, & Brown, 2004; Franssen, Bultmann, Kant, & van Amelsvoort, 2003).

Individuals who report fatigue often report other overlapping symptoms including
muscle pains, sore throats, inattentiveness, headaches, and unrefreshing sleep
(Fukuda et al., 1994). Stress-mediated fatigue is typically reported in the absence
of other illnesses and is directly correlated with a triggering event, even persisting well
beyond the period of stress. Several endocrine and metabolic dysfunctions have been
postulated to generate fatigue symptoms, yet the physiological mechanisms of fatigue
remain unclear. Studies do suggest a relationship with undersecretion of CRH and
cortisol (Demitrack et al., 1991), while others alternatively show no alteration in the
pituitary-adrenal axis (Young et al., 1998). Interestingly, recent genetic studies have
proposed that certain sequences of DNA that control stress through the hypotha-
lamic-pituitary-adrenal axis and the sympathetic nervous system vary among people
(Goertzel et al., 2006). On the individual basis, response to the hormones and
chemical messengers released by stress are interpreted uniquely (Smith, White,
Aslakson, Vollmer-Conna, & Rajeevan, 2006). Thus, people may have a genetic
predisposition to develop stress-mediated fatigue. This condition, no matter what the
physiological basis, is often chronic and disabling, leading to employeesdecreased
overall health and well-being as well as a decreased ability to meet the job
requirements (Wagner, 1997).
Appetite. Exposure to stressful events has been associated with increased or
decreased appetite (Kandiah, Yake, & Willett, 2008). There are several mechanisms
through which this reaction can occur. For instance, brain-signalling pathways
respond to emotional stressors by rapidly increasing the production of hormones
from the melanocortinergic pathways, namely ACTH and melanocyte-stimulating
hormone (MSH). These in turn have been shown to mediate stress-induced anorexia,
leading to a loss of appetite (Liu et al., 2007). Alternatively, the sympathetic nervous
system mediates release of the amino acid ghrelin from the stomach. Ghrelin, in turn,
creates a hunger response that stimulates mealtime initiation. The normal ghrelin
levels present before a meal are increased by acute stressors, thus creating a need-for-
food state in the body and an increase in appetite (Ochi et al., 2008). While these
mechanisms may function in the immediate stress response, stress-induced cortisol
production tends to exert its effect over longer periods of time. Chronically high
levels of cortisol and ghrelin cause increased body fat stores. These newly formed fat
deposits in turn release the signalling peptide leptin, which decreases appetite
through neurogenic pathways. Leptin is released following the exhaustion phase of
the physiological stress process. This process may account for the recent finding that
21% of respondents reported a significantly lower appetite after a stressful event
(Kandiah et al., 2008). Research on changes in appetite in the occupational stress
and health literature primarily focus on loss of appetite (rather than increase in
appetite), which will be examined in this meta-analysis.
Gastrointestinal problems. There are several specific symptoms that fall into the
category of gastrointestinal problems, including nausea, acid indigestion or heart-
burn, abdominal and stomach cramps (excluding those that are due to menstrua-
tion), and irritable bowel syndrome. There are several physiological mechanisms
through which the stress process can affect gastrointestinal process. For instance,
during the acute stress response, the body produces increased amounts of ACTH.
This sympathetic nervous system mediator delays the stomach emptying phase of

digestion, potentially leading to cramping and aches. Parodoxically, chronic stress
actually leads to increased amounts of the stomach enzyme ghrelin that in turn
increases hunger/appetite (Ochi et al., 2008).
The stress process also worsens the symptoms of heartburn by reducing the
stomachs threshold level for pain. This in turn increases the perceived severity of
symptoms, such as burning ulcers and indigestion (Farre´et al., 2007; Fass et al.,
2008). In much the same way, stress responses in the nerve fibres in the
gastrointestinal track lead to a lower tolerance for the stomachs natural ability to
expand. This leads to increased colonic muscle contractions, which may result in
irritable bowel symptoms or diarrhoea. These symptoms are thought to be secondary
to overactive production and release of corticotropin releasing factor (CRF), a
peptide that mediates stress responses (Keck & Holsboer, 2001).
The current study
We decided to conduct a meta-analysis, the goals of which were four-fold. First, we
quantitatively summarized findings across studies that showed relationships between
peoples reports (perceptions) of specific occupational stressors and physical
symptoms. This was to provide some evidence concerning the magnitude of effects
that speak to the importance of studying stressorsymptom relationships. We report
results for variable combinations where there were sufficient numbers of studies
available. Second, we contrasted the magnitude of correlations across different
stressors to show if the potential effects of some stressors were larger than others.
Such findings can potentially help focus intervention attempts toward those stressors
that are likely to have the biggest impact on health. Third, we compared the
magnitude of correlations across different symptoms within each stressor to show if
the potential effects of stressors varied by the particular symptom. Finally, we
compared results from studies using cross-sectional designs with results from studies
using longitudinal designs to help rule out the possibility that observed relationships
might be due to occasion factors (i.e., shared biases produced by transitory
conditions such as mood), and to show that the potential effects of stressors might
persist over time. Although the nature of all of these studies does not allow for
confident causal conclusions to be drawn, demonstrating relationships both
contemporaneously and over time is a first step.
The studies we meta-analysed assessed physical symptoms by means of employee
self-reports. The nature of these symptoms is such that it would be difficult to use
other than self-reports, since do not normally exhibit physical signs that could be
subjected to a medical test. However, such symptoms can serve as important
indicators of health, as they have been shown to predict a variety of long- and short-
term health outcomes (Benyamini & Idler, 1999; Ferraro & Kelley-Moore, 2001;
Idler & Benyamini, 1997), including mortality (Idler & Benyamini, 1997).
Method
Literature search
In order to locate relevant studies for this meta-analysis, we conducted an electronic
search of bibliographies using the PsycInfo (Psychological Abstracts), ABI/Inform,
6A.E. Nixon et al.
Downloaded By: [University Of South Florida] At: 16:09 27 May 2011
Medline, and Dissertation Abstract International databases. We searched for
published studies up to 2009 that examined the relationship between occupational
stressors and physical health outcomes. Occupational stressors examined in this
review include (lack of) control or autonomy at work, interpersonal conflict,
organizational constraints, role conflict, role ambiguity, workload, and work hours.
Stressors were included that were included in at least five studies that we could locate,
which was the minimum number for a meta-analysis. The following search terms
were utilized: role conflict, role ambiguity, workload, work hours, constraints,
interpersonal conflict, relationship conflict, conflict at work, autonomy, control, well-
being, physical symptoms, symptoms, health, ill-health, and illness. Additionally,
database searches were conducted for two prominent symptom scales in stress
research: the Physical Symptom Index (PSI; Spector & Jex, 1998) and the
Occupational Stress Indicator (OSI; Cooper, Sloan, & Williams, 1988).
Manual searches for the most popular outlets for occupational stress research
were conducted, and included three conferences for the years 2002 through 2009:
these were the Work, Stress, & Health conferences,American Psychological
Association conventions, and the conferences of the Society for Industrial/Organiza-
tional Psychology. We manually searched six journals for the years 1996 through
2009: Work & Stress, Journal of Occupational Health Psychology, Journal of
Organizational Behavior, Journal of Occupational and Organizational Psychology,
Stress & Health, and Anxiety, Stress, & Coping. Additionally, we emailed relevant
electronic mailing lists (listservs) to request unpublished and new work being
conducted. Finally, several prominent authors in this area were contacted in order to
obtain additional samples of published and unpublished work. Given that multiple
search methods were used, we came across similar articles by the same author using
the same or overlapping datasets. Overlapping data only occurred when conference
presentations, dissertations, or unpublished data sets were used, which were then
later published in a peer-reviewed journal. If two versions of the same study reported
some variables in one but not the other, both studies were used. In the case of
overlapping data sets, only one was included in our analyses and the duplicate was
discarded.
Inclusion criteria
Our meta-analysis examined the relationships between a variety of occupational
stressors and physical health outcomes. The studies that were considered for the
meta-analysis had to meet several criteria: (a) the level of analysis had to be the
individual employee as opposed to a group, team, or organization; (b) the study had
to use one or more measures of occupational stressor; (c) the study had to use one or
more measures of physical symptoms; (d) the study had to report a correlation
coefficient, or other statistic that could be converted into a correlation coefficient;
(e) the study must have been conducted with working populations reporting about
naturally occurring job settings, thus excluding laboratory samples or scenario
studies; (f) the data must have been self-report by the employee experiencing the
stressor only and not reported from other sources; and (g) longitudinal data must
have reported the relationship between occupational stressor variables measured at
time one and physical symptoms measured subsequently.

Stressor variables
Interpersonal conflict. Interpersonal conflict refers to negative interactions with
others in the workplace, which can range from momentary disagreements to heated
arguments and bullying. Interpersonal conflict can develop as a result of a
competitive work environment and rude or aggressive behaviour of coworkers,
supervisors, and customers. Interpersonal conflict has also been examined by
separating conflict with supervisors from conflict with coworkers, although the
strength of the associations between interpersonal conflict and employee physical
symptoms did not vary significantly across the supervisors and coworkers in the few
studies that compared them (Bruk-Lee & Spector, 2006; Frone, 2000; Lubbers,
Loughlin, & Zweig, 2005). Therefore, these two sources of conflict were combined by
averaging correlations across sources. Interpersonal conflict included measures of
direct and indirect conflict at work, verbal and physical abuse, and bullying. In the
studies that we surveyed interpersonal conflict was measured with a wide variety of
scales, the most commonly used of which was the Interpersonal Conflict at Work
Scale (ICAWS; Spector & Jex, 1998).
Lack of control. Job control, or job autonomy, is a manifestation of perceived control
in the workplace. High levels of job autonomy indicate that an employee has control
over how or when his or her tasks are performed (Jex, 2002). Studies in this meta-
analysis used measures of both the presence of and lack of control. However, the
relationships examined in this study were based on lack of control, and for any study
reporting relationships between control and symptoms we reversed the sign of the
correlation. The most common measures for control were the Job Content
Questionnaire (JCQ; Karasek, 1985), the Job Diagnostic Survey (JDS; Hackman
& Oldham, 1975, 1976; Idaszak & Drasgow, 1987), and the Leiden Quality of Work
Questionnaire (LQWQ, van der Doef & Maes, 1999).
Organizational constraints. Organizational constraints are situations or environmen-
tal hurdles that impede employees from completing their job duties and hinder job
performance. Organizational constraints can refer to elements of the job, such as not
having job-related information, having limited time and materials, or not having the
necessary job-related authority to be able to complete ones task (Peters & OConnor,
1988). All organizational constraints studies used in this meta-analysis measured
them with either the Organizational Constraints Scale (Spector & Jex, 1998) or the
Job Effectiveness Survey (Eulberg, 1984).
Role ambiguity. Role ambiguity occurs when job-related information is not made
clear, causing an employee to be unsure of his or her job duties and requirements.
Role ambiguity can refer to performance expectations or standards, tasks or duties,
scheduling, and other aspects of the work environment. The most common measure
that we found for role ambiguity was developed by Rizzo, House, and Lirtzman
(1970).
Role conflict. Role conflict occurs when different members of the organization give
employees inconsistent or conflicting information concerning their job demands.
Conflicting or inconsistent information could come from multiple individuals or a
8A.E. Nixon et al.

single person within the organization. The most common measure for role conflict in
the studies that we surveyed was that of Rizzo et al. (1970).
Workload. Workload refers to the amount of work an employee is required to
complete in a given amount of time, along with the effort it takes to complete it.
Workload includes both a quantitative component, such as the amount of work one
is expected to complete, and a qualitative component, or the mental effort required
to complete the tasks. The most common workload measure used was the
Quantitative Workload Inventory (Spector & Jex, 1998).
Work hours. Work hours refer to the amount of time an employee works per unit of
time on average. Work hours were measured in either total number of hours worked
per week or average number of hours worked per day/week.
Physical symptoms. Physical symptoms were necessarily measured via self-report. In
this meta-analysis, analyses were conducted for both total aggregate symptoms and
individual symptoms, specifically backache, headache, eye strain, sleep disturbance,
dizziness, fatigue, appetite loss, and gastrointestinal problems. The majority of
studies only indicated symptoms at the aggregate level, but when individual symptom
data were available, the study was utilized in both total and individual symptoms
analyses. The most commonly utilized physical health/symptom measure was the PSI
(Spector & Jex, 1998).
A complete list of measures for all independent and dependent variables analysed in
this meta-analysis can be obtained from the first author.
Statistical methods
For our analyses, we used the Rosenthal (1991) approach to meta-analysis. The
Rosenthal approach computes descriptive statistics based on the sample of
correlations that are similar to the bare-bones approach outlined by Hunter and
Schmidt (1990). The primary differences between these approaches is that the Hunter
and Schmidt approach recommends estimating how much observed variance in
correlations can be attributed to artefacts such as sampling error or unreliability of
measures by applying adjustment formulas. These formulas are also used to estimate
the underlying theoretical population parameters by allowing for the adjustment of
the observed mean correlations. These adjustments can be problematic and
inaccurate (e.g., James, Demaree, & Mulaik, 1986; Rosenthal, 1991; Spector &
Levine, 1987), particularly when analysing a relatively small number of studies per
variable, as is the case with some of our variable combinations in this meta-analysis.
Additionally, the most frequent correction applied in the Hunter and Schmidt
approach is unreliability in the criterion. Our studies did not routinely report internal
consistencies for total symptom scores, and no measures of reliability were reported
for single-item measures of individual symptoms. Data from longitudinal studies
were dealt with separately from cross-sectional studies.
The coding process included identifying the relevant correlations and sample
sizes for studies that met our inclusion criteria. When the sample size was reported as
a range, a conservative approach was employed by taking the minimum of the range.

confidence intervals used to draw conclusions about the significance of the mean
correlations, we multiplied the standard deviation of the mean by 1.96 and then
added and subtracted the result from the mean correlation as recommended by Lee
(1989).
Results
Our literature search returned a total of 510 published journal articles, dissertations,
and unpublished papers/data that concerned occupational stressors and health
outcomes. Studies were screened according to the inclusion criteria described below.
We found 79 studies that fitted the inclusion criteria; 64 were journal articles, 7 were
theses or dissertations, 4 were conference presentations, and 4 were unpublished data
sources. For cross-sectional relationships between occupational stressors and
composite physical symptoms, the literature search yielded 313 correlations. The
number of samples per variable for the cross-sectional analyses ranged from 25 to 92
for composite symptoms analyses and 3 to 40 for the analysis conducted at the
individual symptom level. The number of samples per variable for longitudinal
analyses ranged from 2 to 7.

excluded zero, indicating that the relationships with composite scores from physical
symptom inventories are significantly different from zero.
The meta-analytical results indicated that we can classify the stressors into three
groups based on strength of relationship with physical symptoms, using z-tests for
independent correlations to determine significant differences in effect sizes.
Organizational constraints had the strongest mean weighted correlation (wr) with
overall physical symptoms; wr .33. This relationship was significantly stronger
than all of the other relationships between occupational stressors and physical
symptoms. The next largest mean correlation was for role conflict (wr.27), which
was significantly larger than for the remaining variables. Next was interpersonal
conflict (wr.22), and workload (wr.22), both of which were significantly larger
than for the remaining variables. Next was role ambiguity (wr .15), which was
significantly different from that of the other variables. Finally, work hours (wr.09)
and lack of control (wr .07) had significant relationships with the composite
physical symptoms. These last relationships did not differ from one another,
although they were significantly smaller than other occupational stressors relation-
ships with physical symptoms, as demonstrated by the exclusive confidence intervals.
Longitudinal relationships between composite physical symptoms and occupational
stressors
All of the occupational stressors had been examined in relation to composite physical
symptoms in a longitudinal context (see Table 1). Time frames across studies varied
considerably from one month to more than a year, and given the limited numbers of
studies, time frames were not the same across stressors. As can be seen in Table 1, six
of eight mean correlations were significantly different from zero (all but interpersonal
conflict, which had a small sample size [N110], and working hours). The
magnitudes of the relationships between three of the longitudinal mean correlations
(organizational constraints, role conflict, and work hours) were not significantly
different from the cross-sectional results based on z-tests. Three of the longitudinal
relationships (interpersonal conflict, role conflict, and workload) were significantly
smaller, and one longitudinal relationship (lack of control) was significantly larger in
magnitude when compared to cross-sectional relationships. Additionally, the
relationship between work hours and physical symptoms was found to be non-
significant in the longitudinal context and significant in the cross-sectional context.
Individual physical symptoms and occupational stressors
The individual symptom analysis revealed that the occupational stressors did
differentially relate to individual strains (see Table 2ac). Interpersonal conflict,
organizational constraints, and workload were significantly related to every physical
symptom, although there was a different pattern in relative strength of relationship
across these stressors. Interpersonal conflict had a significantly larger mean
correlation with sleep disturbances than with dizziness, headaches, or fatigue.
Organizational constraints had significantly larger mean correlations with fatigue
and gastrointestinal problems than the other symptoms. Workload had a larger mean
correlation with fatigue, followed by its relationship with eye strain, which were both
significantly larger than the relationship with the other symptoms. Workload had

significantly larger mean correlations with appetite loss and dizziness than headaches
and sleep disturbances, based on results from z-tests.
Role conflict and work hours were each significantly related to five of the eight
physical symptoms examined. Role conflict had positive relationships with back-
aches, dizziness, eye strain, gastrointestinal problems, and sleep disturbances. Role
conflict had a significantly larger mean correlation with gastrointestinal problems
than with headaches, based on results from z-tests. Work hours had positive
relationships with appetite, eye strain, fatigue, gastrointestinal problems, and sleep
disturbances. Work hours had a larger mean correlation with fatigue than all other
symptoms except eyestrain. Work hours had a larger mean correlation with eyestrain
than backaches, headaches, dizziness, and appetite loss. Additionally, work hours
had a significantly smaller relationship with backaches than all other symptoms with
the exception dizziness. Lack of control had positive relationships with four of the
physical symptom variables, including backaches, gastrointestinal problems, head-
aches, and sleep disturbances. Backaches and sleep disturbance had larger mean
correlations with lack of control than headaches and appetite loss. Additionally, lack
of control had a smaller mean correlation with eye strain than backaches, headaches,
sleep disturbances, fatigue, and gastrointestinal problems. Finally, role ambiguity
was only significantly related to fatigue; this relationship was significantly larger than
the relationships between role ambiguity and eyestrain or appetite, based on z-tests.
None of the physical symptoms related to all of the occupational stressors.
However, gastrointestinal problems and sleep disturbances were significantly related
to more occupational stressors than any of the other physical symptoms, each having
significant relationships with six of the seven occupational stressors examined.
Backaches, eye strains, and fatigue were each related to five occupational stressors.
Changes in appetite, dizziness, and headaches showed the fewest significant
relationships with occupational stressors, each relating to four occupational stressors.
Discussion
Physical symptoms as defined in our study are manifestations of physical strain that
are likely to be responses to environmental stressors at work. Such strains are
particularly important given that they are predictive of future morbidity and
mortality as well as absenteeism (Benyamini & Idler, 1999; Darr & Johns, 2008;
Ferraro & Kelley-Moore, 2001; Idler & Benyamini, 1997). The goal of this meta-
analysis was to quantitatively summarize the cross-sectional and longitudinal
relationships between occupational stressors and both composite and individual
self-reported physical symptoms. These relationships had not been as thoroughly
examined previously in a meta-analysis. Results demonstrate that occupational
stressors were related to physical symptoms both cross-sectionally and over time.
Additionally, certain physical symptoms, including gastrointestinal problems and
sleep disturbances, were related to more occupational stressors than other symptoms,
such as dizziness or headaches. In the following section, we will discuss the
relationship patterns identified in these analyses mechanisms that may help
explain these relationship patterns, as well as relevant research and practical
implications and opportunities.

Composite symptoms and occupational stressors
All of the occupational stressors included in this meta-analysis were significantly and
positively related to composite physical symptoms in the analysis of cross-sectional
studies, although relationships with physical symptoms were stronger for organiza-
tional constraints, role conflict, interpersonal conflict, and workload than for role
ambiguity, work hours, and lack of control. Longitudinal analyses, while hindered by
the limited number of available studies (k2 to 7), provide some evidence for
temporal consistency of the stressorphysical symptom relationships. Importantly,
the effect sizes of the longitudinal relationships between some of the occupational
stressors were not significantly different from the cross-sectional results. Specifically,
longitudinal relationships between interpersonal conflict, workload, and working
hours were positive and not significantly different from the corresponding cross-
sectional relationships. It should be kept in mind that the sample sizes for
some stressors in the longitudinal studies was rather limited, thus not providing
adequate statistical power. For example, the largest correlation with the longitudinal
studies was for organizational constraints (r.18), which was non-significant,
although only based on a sample size of 110.
Our results show that three of the four stressors (organizational constraints,
interpersonal conflict, and workload) relating most strongly to overall symptoms are
the same that have consistently emerged as most salient in qualitative studies of
stressful work incidents (e.g., Keenan & Newton, 1985; Liu, Spector, & Shi, 2007;
Narayanan, Menon, & Spector, 1999). Perhaps these stressors are reported more
frequently in qualitative research because they have a stronger impact on strains,
including physical symptoms, and thus the stressors are more salient to employees.
Thus, employees might judge the severity and impact of a stressor by the
physiological reaction that follows the stressor. On a different note, this pattern of
meta-analytic findings has implications for the ways in which occupational stressors
are conceptualized. Specifically, our results show that both chronic stressors (i.e.,
organizational constraints, role conflict) and acute stressors (i.e., interpersonal
conflict) can have significant relationships with employeeshealth; therefore further
examination into both types of stressor is essential. Additionally, research addressing
the underlying mechanisms for acute and chronic stressors is warranted, as these
chronic and acute stressors may impact on physical symptoms through unique
underlying mechanisms. Finally, this pattern of results can help guide intervention
and restructuring efforts by organizational leaders concerned with the physical health
of their employees. Reducing organizational constraints and role conflict may be
effective and accessible ways to reduce employeesphysical symptoms that might
play a role in more serious health problems.
Immediacy of physiological reactions and specific symptoms
The individual symptom analyses revealed differences and patterns across relation-
ships between occupational stressors and physical symptoms. We propose that the
immediacy of physiological reactions represents an underlying mechanism that is
useful in understanding many of these diverse relationships. Taking all of the
occupational stressorindividual symptom relationships into account, gastrointest-
inal problems and sleep disturbances were significantly related to more occupational
14 A.E. Nixon et al.

stressors than the other physical symptoms. One reason that individuals may
frequently report these physical symptoms is that they are the by-product of
immediate physiological reactions. Experiences of increased levels of physical and
mental stressors initiate an immediate physiological reaction involving elevated
ACTH and sympathetic nervous system agonists, which create the rapid response of
slowing digestion and causing an upset stomach. The time period for this reaction to
occur is minimal, leading to the almost instantaneous perception of the physical
symptom, and an awareness that a stress reaction has taken place. The fact that many
people report gastrointestinal reactions is probably secondary to this strain being one
of the first noticed and easily relatable symptoms to stressors.
In much the same way, sleep patterns may vary in the immediate setting as well.
As the body enters a stressful situation, its sympathetic nervous system activity is
elevated. The hormones generated by the ‘‘fight or flight’’ response may cause lasting
tension and eventually disrupt sleep. In fact, the very mechanisms needed to gain
sleep are the opposing mechanisms driven by the ‘‘fight or flight’’ response; they
specifically include blood pressure, heart rate, and respiratory rate. A disruption of
these mechanisms may lead to ineffective sleep, which is often an immediate outcome
and one that is, like gastrointestinal problems, easily attributable to stressors.
A promising area for future research could be examining the role that mental
rumination, or replaying and dwelling on a stressful event, may play in sleep
disruption by increasing anxiety and stress reactions (Cropley, Dijk, & Stanley,
2006).
Many of the other symptoms, including backaches, headaches, eye strain, and
loss of appetite, represent physical reactions that generally develop over time.
Stressful events are often related to increased complaints of pains and strains weeks
after the initial incident (Davis et al., 2001; Manne & Zautra, 1989; Zautra et al.,
1998; Zautra et al., 2005). When individuals experience stressors, the bodys pain
threshold is decreased while the pain signalling pathways become increasingly
sensitive (Huyser & Parker, 1999; McLean et al., 2005; McLean et al., 2006). Thus,
the nervous system becomes overly sensitive to pain signals, such that even the
slightest insult to the system may cause symptoms such as headaches, back pains, or
eye strains.
Elusively, transient and subtle symptoms may not be as easily explained by the
immediacy of physiological responses. These symptoms, such as dizziness, are easier
to miss or otherwise explain away. Dizziness passes quickly, thus individuals may
take little note of this reaction, while backache remains more pervasive over long
periods of time, making it more likely that individuals will be concerned about back
pain and recall it when completing a symptom checklist. This alternative hypothesis
should be evaluated through future research.
The immediacy of physiological responses in reaction to stressors reinforces the
need for longitudinal research examining physical reactions to occupational
stressors. Currently, to our knowledge individual symptoms related to occupational
stressors have not been examined in a longitudinal research setting. This is an
important next step for this area of research, as the relationships between these
variables may vary over time. In particular, time series designs would be useful in
examining the development of chronic physical symptoms, as well as changes such as
habituation or further progression to chronic illnesses.

Fatigue
Fatigue is somewhat unique among the individual symptoms that were examined in
this study. Unlike the other seven symptoms, fatigue is a condition that can be
associated with other symptoms, including muscle pains, headaches, and unrefresh-
ing sleep. Consequently, the relationships between fatigue and occupational stressors
may be explained through additional means than the other physical symptoms. One
potential reason that fatigue is a very frequently reported strain is that it is the most
easily recognizable and often disabling consequence of chronic stress (Dittner et al.,
2004; Franssen et al., 2003). Alternatively, the multidimensional nature of fatigue
may itself account for the frequency with which it is reported. If individuals report
fatigue when any combination of symptoms is present, it might receive more frequent
endorsements than a uni-dimensional symptom, such as back pain. In the future,
researchers should consider studying reports of fatigue in more depth, to gain a
better understanding of how occupational stressors impact on this constellation of
symptoms.
Limitations
Despite an extensive search of both published and unpublished literature in an
attempt to include as many effect sizes as possible given our inclusion criteria, a few
of the findings reported here are based on a small number of studies and, therefore,
require more careful consideration. This is particularly relevant when interpreting
the longitudinal results and the findings associated with several occupational
stressors and individual physical symptoms. Given the inability to draw causal
conclusions from cross-sectional data, it is important that researchers conduct more
longitudinal research in this area. As more longitudinal research is conducted, the
nature of longitudinal relationships should be examined in comparison to the cross-
sectional relationships to search for emerging differences.
Another limitation particular to the individual symptom analyses is that many
had low incidence rates, thereby attenuating the magnitude of possible correlations.
One reason that individual symptoms are often combined into composite indices is
to increase the range and variance of the measure, thus increasing the likelihood of
finding significant relationships. Our results suggest that relationships of individual
symptoms can vary across stressors, which argues against combining symptoms into
composites. At the very least one needs to be cautious not to interpret composite
scores to mean that all components of the composite are necessarily related to
stressors (or other variables) or that the magnitude of relationships are equivalent
across components.
There are also sources of potential bias that plague meta-analytic work, and this
project is no exception. First, there is always the danger than these results suffer from
publication bias that produces the ‘‘file drawer’’ problem in which only significant
results are published. It is possible that our results over-estimate the size of stressor
symptom relationships due to this limitation. However, it should be noted that many
of the studies in our meta-analysis included measures of psychological strains that
generally show stronger stressorstrain relationships. It seems unlikely that an
author would fail to publish a study just because there were small or nonsignificant
relationships with physical symptoms, as psychological strains would likely show
16 A.E. Nixon et al.
Downloaded By: [University Of South Florida] At: 16:09 27 May 2011
significant results. Furthermore, in an attempt to address these sources of bias, we
included conference presentations, dissertations, and unpublished studies that would
not be subject to the same publication biases, unless it is the case that authors are
reluctant to share null results. Nevertheless, as with any meta-analysis, we cannot be
certain that we did not have a biased sample of studies.
Furthermore, the studies included in our meta-analysis were entirely self-report
with all measures coming from a survey of employees. Thus we can say that
perceptions of stressors relates to reported symptoms. What cannot be determined
from such designs is the extent to which these relationships generalize to actual
environmental exposure. In other words, is it the amount of the stressor (e.g., number
of constraints) or merely the perception? This is important as it determines whether
interventions should focus on the environment or the individual. If the former, then a
focus on changing the environment would likely be most important, for example, by
shifting workloads to relieve overwork, or hiring more staff to reduce overtime hours.
On the other hand if the environment itself is unimportant, a focus on the individual,
perhaps through stress management training focused on cognitive restructuring
should be the target of intervention.
Another limitation to single-source designs is whether observed correlations are
distorted by shared biases among variables. For example, are people who are high on
neuroticism predisposed to be negative and complain, thus giving high ratings on
stressor and symptom scales? One possible mechanism by which biases could arise is
attributions: that is, the way in which an individual attributes a cause to an effect.
Individualsschemata of strains may consist of more immediate reactions, such as
abdominal and stomach cramps and fatigue, as opposed to long-term reactions, such
as eye strain. It may be that while responding to a survey about stressors, this strain
schema is activated, leading individuals to report more immediate physical strains.
This mechanism could also potentially explain why dizziness is less often reported as
a physical symptom associated with occupational stressors. While dizziness is an
immediate reaction to stress, in our findings it did not demonstrate a similar pattern
of relationships with occupational stressors as did the other immediate physical
symptoms, perhaps because dizziness is not primarily attributed to the physiological
stress process (Kasper et al., 2005).
The attributional process could potentially inflate relationships between
stressors and strain. For instance, individuals who have reported many symptoms
that they believe relate to stressors might then inflate reports of stressors, or
individuals who report frequent and intense experience of occupational stressors
might then inflate symptom reports. In the future it would be interesting to
investigate how schemata about the impact of occupational stressors on physical
health might impact on self-reported physical symptom data. The lack of research
concerning the role of attributional processes in which individuals engage when
responding to stressor and strain surveys is a substantial hindrance in the
development and advancement of this field, and one that critically needs to be
addressed in future research.
Conclusions
We believe that this study advances knowledge and provides a platform for
researchers to better understand the relationships between occupational stressors

and employeesphysical health, as well as provide pointers to essential next steps in
this research area. All of the occupational stressors examined were significantly
related to composite ratings of physical symptoms, with organizational constraints,
role conflict, interpersonal conflict, and workload having the strongest relationships
with physical symptoms. Studies that examined longitudinal relationships between
these occupational stressors and physical symptoms provide some evidence for the
temporal consistency of symptoms, and help control for transient occasion factors
that could distort observed relationships.
Based on our findings, we conclude that physical symptoms are a vitally
important strain to continue studying in occupational health research, not just
because of the possible severity of outcomes, which can be highly related to morbidly
and mortality, but also because physical symptoms are affected by a wide range of
occupational stressors and these relationships can prevail over time.
By examining the relationships between occupational stressors and specific
physical symptoms (rather than composite symptoms), we identified that there were
differences across these relationships. Furthermore, a novel feature of this study is
the distinction that was drawn between immediate and delayed physiological
responses to stressors. This immediacy of physiological responses was proposed as
a mechanism to explain differences in relationships between stressors and specific
physical symptoms. We have also drawn attention to the importance of under-
standing how individualsattributions about the nature of physical responses to
stressors may relate to stressorphysical symptom research. Future research
examining the diverse relationships between occupational stressors and physical
symptoms, as well as potential underlying mechanisms, may lead to changes in the
research methodology currently used to study physical symptoms, such that they may
be better examined by multidimensional scales, rather than the uni-dimensional
scales currently employed.

Grounded in and expanding upon the allostatic load model, the present study examined how repeated exposure to work and nonwork stressors (i.e., stressor pile-up) across an 8-day study period relates to daily strain-related outcomes—diurnal cortisol, physical symptoms, and sleep quantity and quality—in both parents and their adolescent children. Nonlinear associations between daily stressor pile-up and daily strain were explored. Data from the Work, Family, and Health Network study (N = 131 parent–child dyads, n = 1,014 daily survey observations, n = 465 daily observations with cortisol) were used to test the study hypotheses. Parent work stressor pile-up and adolescent stressor pile-up were associated with increased daily physical symptom likelihood in parents and adolescents, respectively. Counter to expectations, parent nonwork stressor pile-up was associated with steeper daily cortisol slopes. Additionally, we found curvilinear crossover effects for sleep quantity, such that parent nonwork stressor pile-up and adolescent stressor pile-up were associated with shorter sleep duration among adolescents and parents (respectively), but this relationship plateaued and reversed as daily pile-up increased to more extreme levels. Our article explores conceptual and operational pile-up definitions (level of analysis, length of time window, inclusion of the current-day stressor events). Individual-level analyses supported more consistent, positive linear relationships between stressor pile-up and strains. Time window had little consequences for conclusions, but inclusion of the current day yields some alternative conclusions. We discuss implications for understanding stressor pile-up across domains and across parent–child dyads as it relates to daily strain within the family system.

Although workplace stress is one of the most heavily studied topics in occupational health psychology, one relatively unexplored area within the field of organisational stress is the reporting of stress-related problems in the workplace (Britt et al. 2016). A study by Nixon et al.

The main issue addressed in this study is the low level of employee job satisfaction at the Faculty of Economics and Business, Universitas Negeri Padang, which is suspected to be caused by high workload and increased burnout levels. This research aims to examine the effects of workload and burnout on employee job satisfaction. A quantitative approach with a survey technique was employed. Primary data were collected through questionnaires distributed to the entire population of 37 employees using total sampling. Data analysis was conducted using SPSS through validity and reliability tests, classical assumption tests, multiple regression analysis, and hypothesis testing. The results indicate that workload (X₁) and burnout (X₂) have a significant negative effect on job satisfaction (Y), meaning that higher workload and burnout levels correspond to lower employee job satisfaction. The study concludes that management plays a crucial role in managing workload and reducing burnout to create a healthier and more supportive work environment. Practical implications include the need for organizational policies that balance workload and prioritize employee well-being to sustainably enhance job satisfaction and productivity.
... Chronic work-related stress has been demonstrated to have detrimental impacts on an individual's emotional well-being and overall quality of life [4]. Loss of energy and efficiency, mental and physical strains, and absence from work owing to burnout or other forms of mental health impairments are common consequences of unaddressed stress [5][6][7]. The study by Nekoei et al [8] recorded the suspected economic costs attributable to burnout as >2% of the national labor income, which demonstrates a continuous increase in workloads and speaks of an "epidemic of burnout" [9] affecting all fields of occupation, although some of them, such as health care, school education, or geriatric care, are particularly affected [10,11]. ...

Background Occupational stress is associated with detrimental consequences that are addressed by mobile health (mHealth) solutions. Previous developments of apps for occupational stress have not yet fully exploited the potential of multilevel diagnostics through the integration of wearable sensors for interventions. Personalizing mHealth approaches in terms of intervention time and content, which requires the use of artificial intelligence, is the next logical developmental step. The "Relax" approach developed a corresponding prototype of an app-wearable system, which will be evaluated for effectiveness in terms of stress reduction and usability. Objective This study protocol describes an evaluation study used to test the effectiveness and usability of the Relax approach. Methods The evaluation study was designed as a 2-arm randomized trial with 2 phases, each with a 3-week intervention period. In both phases, employees were required to use the app to record daily stress and to wear a wearable sensor to measure heart rate variability. The app offered interventions based on algorithms, which altered the probability of their selection after learning from the data, thereby personalizing the user experience. In the second phase of the study, the sample was divided into 2 groups, varying the degree of personalization of the app. To analyze effectiveness, a 2-factorial mixed within-between design will be applied to compare the outcomes between both groups as well as in a pre-post comparison. In addition, exploratory analyses of the usability of the approach are planned. Results The study was conducted during the spring and summer of 2024, with a total of 46 participants enrolled, and is ready for data analysis. Conclusions The Relax approach, including a number of factors related to personalization that have not yet been incorporated into mHealth in current research, will provide new insights into the next steps of advanced mHealth solutions. Limitations of the study design, such as the lack of a control group and the sample representativity, have to be addressed.

Background This study introduces a rippleeffect model that links Quality of Work Life (QWL), Psychological well-being (PWB), Organizational Role Stress (ORS), and Organizational Citizenship Behavior (OCB) within Indian universities—a context seldom examined as an integrated system. The aim is to show how QWL propagates through PWB and ORS to influence faculty citizenship behavior, thereby filling a gap in multivariate stress research. Methods Data were collected from 303 permanent faculty members in public and private universities in West Bengal, India. Participants completed validated scales for QWL, PWB, ORS, and OCB. Dimensional scores served as indicators. Reliability was assessed via Cronbach’s α and composite reliability (all ≥ 0.82). Harman’s singlefactor test confirmed negligible commonmethod variance. Hypotheses were tested with structuralequation modeling in AMOS; the model fit was evaluated with CFI, TLI, RMSEA, and SRMR. Results The final model showed a good fit (CMIN/df = 1.76; CFI = 0.92; TLI = 0.91; RMSEA = 0.05). QWL was positively associated to PWB (β = 1.00, p <.001) and negatively associated to ORS (β = − 0.15, p =.021). PWB was associated to reduced ORS (β = − 0.12, p =.002) and increased OCB (β = 0.07, p =.002). ORS has a strong negative association with OCB (β = − 0.51, p <.001). Mediation testing revealed that PWB partly mediated the QWL → ORS pathway, while ORS mediated both QWL → OCB and PWB → OCB. A sequential mediation (QWL → PWB → ORS → OCB) was also significant (β = 0.06, 95% CI = 0.023–0.108). The ripple effect model explained 63% of OCB variance. Conclusions This study reveals how systemic QWL improvements cascade through psychological and stress-related mechanisms to foster prosocial behaviors. It advances organizational stress theory by demonstrating these dynamics in a high-pressure academic context. Practical implications suggest prioritizing workload autonomy, and flexible policies to enhance well-being and institutional performance. The findings highlight the need for holistic, organization-level interventions over individual-focused approaches.

Although peace is invariably regarded as a universal good, most research focuses on ‘outer’ forms (e.g., societal relations), with little attention to ‘inner’ peace (IP, i.e., tranquil states of mind). This may reflect the Western-centrism of academia, with low arousal positive states like IP being relatively undervalued in the West. But alongside broader efforts to redress such Western-centricity, an emergent literature is now exploring this concept. This report adds to this by presenting the most ambitious longitudinal study to date of IP, namely as an item – “In general, how often do you feel you are at peace with your thoughts and feelings?” – in the Global Flourishing Study, a five-year (minimum) panel study of the predictors of flourishing, involving (in this first year) 202,898 participants from 22 countries. This paper looks at demographic variation vis-à-vis IP, with our primary analyses consisting of meta-analyses across countries for each demographic group, focusing on three research questions. (1) What are the distributions and descriptive statistics of key demographic factors? (2) How does IP order across countries, with considerable variation observed, with the percentage always or often at peace ranging from 89% (95% CI = 87,90) in Hong Kong to just 49% (0.46,0.52) in Turkey. (3) How does IP vary across demographic categories, with the greatest variation among those always/often at peace observed in relation to age (68% [63,73] of 18–24 year olds versus 86% [73,94] of the 80+), followed by employment status (63% [0.57,0.68] of unemployed job-seekers versus 78% [65,75] of retirees), then religious attendance (68% [62,73] for non-attendees versus 80% [73,85] for more than once weekly). The results shed new light on the personal and contextual factors that shape this valued yet under-studied outcome, and provide a helpful foundation for further enquiry.

The importance of balance has been selectively acknowledged in modern scholarship through notions such as work-life balance. However, the broader notion of balance in life has remained underappreciated. This may reflect the Western-centric nature of academia, with balance having received less attention in the West compared to other cultures. But aligning with efforts to make scholarship more globally inclusive, an emergent literature is exploring this concept. This report adds to this by presenting data from the most ambitious longitudinal study to date of life balance, as an item – “In general, how often are the various aspects of your life in balance?” – in the Global Flourishing Study, a five-year (minimum) panel study investigating the predictors of flourishing involving (in this first year) 202,898 participants from 22 countries. Reporting on wave 1 of the study, this paper looks at demographic variation vis-à-vis life balance, with our primary analyses consisting of meta-analyses across countries for each demographic group, focusing on three research questions. First, what are the distributions and descriptive statistics of key demographic factors. Second, how do levels of balance order across countries, with considerable variation observed, with the percentage either always or often in balance ranging from 83% in Israel to just 44% in Tanzania. Third, how does balance vary across demographic categories, with the biggest difference in relation to employment status (with 76% of retirees often or always in balance, versus 57% of those unemployed/seeking a job), and the smallest in relation to immigration status. These results shed new light on the personal and contextual factors that shape this valued outcome, and provide the foundation for further enquiry.
... While physical health refers to one's overall physical condition and perceived limitations in physical activities in daily life, mental health describes one's overall psychological condition and perceived limitations in daily social activities and emotional functioning (Ware et al., 1996).

In this study, we integrate propositions of conservation of resources theory and role theory to examine between-person and reciprocal within-person relations among leader health, leader identity, and three forms of leadership behavior (i.e., transformational, contingent reward, and laissez-faire leadership). We collected monthly data from N = 1,244 leaders in a four-wave fully crossed and lagged panel study. To separate stable (i.e., between-person) differences from dynamic (i.e., within-person) relations, we analyzed the data using a random intercept cross-lagged panel model (RI-CLPM). At the between-person level, we found that leaders with better physical and mental health and reduced symptom experience engage in more transformational and contingent reward leadership and less laissez-faire leadership. At the within-person level, both symptom experience and mental health positively predicted laissez-faire leadership, and laissez-faire leadership positively predicted symptom experience. We did not find support for within-person relations between leader health and transformational and contingent reward leadership, and we found no evidence for mediating effects of leader identity in the relations between leader health and leadership behavior. We discuss these differential findings and their implications for promoting leader health in organizations and theorizing on temporal processes in research on leader health and leadership

This research investigates the comparative effectiveness of acupressure and aromatherapy in alleviating menstrual pain among adolescent girls. Menstrual pain, or dysmenorrhea, is a common and often debilitating condition that affects a significant number of young women, prompting the need for accessible and effective non-pharmacological treatment options. A total of 100 adolescent participants experiencing menstrual pain were randomly assigned to two intervention groups: one receiving acupressure treatment and the other using aromatherapy with essential oils. Pain intensity was measured using a visual analog scale (VAS) before and after the interventions. Results indicated that both acupressure and aromatherapy significantly reduced menstrual pain, with the acupressure group showing a greater mean pain reduction of 4.2 points compared to 3.5 points in the aromatherapy group. These findings support the efficacy of both interventions as viable alternatives to traditional pharmacological treatments. The study emphasizes the importance of integrating non-pharmacological approaches into adolescent healthcare to empower young women in managing their menstrual discomfort. Limitations such as small sample size and reliance on self-reported pain measures are acknowledged, highlighting the need for further research to explore the long-term effects and broader applicability of these interventions. Overall, this study contributes to the growing body of evidence advocating for holistic pain management strategies in adolescent health care.

This study examined the relation between work-family conflict and several types of psychiatric disorders: mood, anxiety, substance dependence, and substance abuse. Survey data were obtained from a representative national sample of 2,700 employed adults who were either married or the parent of a child Ig years old or younger. Hierarchical logistic regression analyses revealed that both work to-family and family-to-work conflict were positively related to having a mood, anxiety, and substance dependence disorder. Depending on the type of wort-family conflict and type of disorder, employees who reported experiencing a work-family conflict often were 1.99-29.66 times more likely than were employees who reported no work-family conflict to experience a clinically significant mental health problem. No support was found for gender differences.

The dimensionality of the original Job Diagnostic Survey (JDS) and a revision were investigated. Factor analyses of two data sets identified six dimensions underlying the original JDS. Five of the factors correspond to the pattern expected for the JDS items; the sixth was identified as a measurement artifact. Five of the JDS items were subsequently rewritten to eliminate the artifact. The revised survey was administered to employees of a printing company (N = 134) and the a priori five-factor solution was obtained with no artifact factor. Scale–factor correlations were also computed. The resulting coefficients suggest that the revised JDS scales are measuring their underlying constructs with reasonable accuracy. As a result of the measurement artifact in the original JDS, it is recommended that the revised JDS should be used in future research concerned with task characteristics.

Objective. The effects of interpersonal stress on disease activity were examined for married women with rheumatoid arthritis (RA) who differ in the quality of their relationships with their spouses. Methods. Measures of interpersonal events were collected weekly for 12 weeks and related to disease activity through a comparison of clinician ratings and immune markers taken at baseline and during a highly stressful week for 20 RA patients. Individual differences in marital relationship variables and illness characteristics were used to predict group differences in how stress affected disease activity. Results. Significant elevations in total T cell activation (DR + CD3 cells), soluble interleukin-2 receptor (sIL-2R), and clinician's global ratings of disease activity were found during a week of significant interpersonal stress. However, women with better spousal relationships did not show increases in disease activity following an episode of interpersonal stress. In addition, patients taking low-dose prednisone showed greater reactivity to stress than patients not currently using glucocorticoid treatment. Conclusion. The results are consistent with the hypothesis that disease activity in RA increases following increases in interpersonal stress and that women with stronger marital relationships were less vulnerable to those stressors.

A biopsychosocial framework is presented for the experimental study of interactions between environmental demands, stress, and health. Physiological responses to the psychosocial environment reflect the cognitive and emotional impact on the individual and serve as “early warnings” of long-term health risks. Research on the release of catecholamines and Cortisol in response to different psychosocial demands is interpreted in terms of the author's activity-affect model of stress. It is argued that neuroendocrine correlates (e.g. the catecholamine/cortisol ratio) of activity vs. passivity and positive vs. negative affect are potent determinants of health outcomes. The role of personal control as a mediator of positive affect is emphasized. A review of studies of catecholamine reactivity over the past two decades shows that sex differences have decreased markedly—an increasing proportion of women are reacting to achievement demands as strongly as men. The increasing similarity between the sexes on the physiological level reflects the increasing similarity in men's and women's roles. Possible adverse health consequences of women's multiple roles and heavy total workload are considered in the light of new epidemiological data. Special attention is given to potential health risks for women in managerial positions, who have a particularly heavy workload and tend to “unwind” slowly after work.
