Work and depression: The moderating role of personality traits

The moderating role of physical activity on the relationship between work intensity and depressive symptoms among the employees

Our aim was to examine the associations between work intensity and depressive symptoms among the working population, as well as to identify the impact of physical activity (PA) on these relationships. Spearman correlation analysis was conducted to analyze the correlations among work intensity, PA, and depressive symptoms. Working hours and working days were positively correlated with depressive symptoms (r = 0.108, 0.063; all p values were <0.001). Regular PA, exercise time, exercise frequency, and exercise years were negatively correlated with depressive symptoms (r = -0.121, -0.124, -0.152, -0.149; all p values were <0.001) and working days (r = -0.066, -0.050, -0.069, -0.044; all p values were <0.001), working hours (r = -0.113. -0.106, -0.161, -0.123; all p values were <0.001). Working days was positively correlated with working hours (r = 0.512, p < 0.001). Different levels of PA alleviated the effect of working hours or working days on depressive symptoms. Working hours seemed to be more correlated with depressive symptoms than working days. The results suggest that PA at any level could buffer against the effects of work intensity and might prove a helpful strategy for improving mental health issues among employees.

Depressive symptoms in helping professions: a systematic review of prevalence rates and work-related risk factors

OBJECTIVE

The aim of this study is twofold. Our first aim is to provide an overview of the prevalence rate of depression in a wide array of helping professions. Our second aim is to identify work organization conditions that seem to be associated with this depression risk.

METHODS

Four databases were searched (CINAHL, PsycInfo, PubMed, and Web of Science) yielding 87,626 records in total. We were interested in identifying depression prevalence rates and work-related variables that have been found to contribute to depression in helping professions.

RESULTS

In total, this systematic review included 17,437 workers in more than 29 countries. Depression prevalence rate varied between 2.5% and 91.30%. The two most frequently reported professions were nurses and doctors with 73.83% and 30.84% of studies including nurses and doctors in their sample. Work factors contributing to depression included: skill utilization, decision authority, psychological demands, physical demands, number of hours worked, work schedule (irregular or regular), work schedule (daytime or night time), social support from coworkers, social support from supervisor and the family, job insecurity, recognition, job promotion, and bullying.

CONCLUSION

The results of this study highlight alarmingly high rates of depression in helping professions and should serve as a reminder to pay close attention to the mental health of those workers. Investing in employees' mental health by preventing and reducing depression risk could prove to be a valuable investment from an employer's point of view, as it is likely to increase productivity and reduce absenteeism among a host of other positive outcomes.

A multilevel analysis of the role personality play between work organization conditions and psychological distress

BACKGROUND

Psychological distress in the workplace is usually attributed to work-related variables as well as non-work-related variables. Individuals working in the same organization can differ in terms of their appraisal of work-related stressors and coping strategies used to face them. The present study aims to evaluate the moderating role personality plays between work organizations conditions and psychological distress in a large sample of Canadian participants working in various occupations and workplaces.

METHODS

Multilevel regression analyses were conducted on a sample that followed a hierarchical structure with workers (N1 = 1958) nested in workplaces (N2 = 63). The direct contribution of workplace and personality was tested in a variance component model as a first step. Following this initial step, we introduced interaction variables by blocks of 11. Those interaction variables refer to each interaction combined with a specific personality variable.

RESULTS

Psychological demands, number of hours worked, job insecurity, neuroticism, and agreeableness were associated with higher levels of psychological distress. Inversely, decision authority, job recognition, self-esteem, locus of control were associated with lower levels of psychological distress. Lastly, agreeableness played a moderating role between low social support garnered from one's supervisor and psychological distress.

CONCLUSIONS

To intervene on work-related variables, organizations could reduce psychological demands, minimize the number of hours worked through job redesign, allow teleworking and encourage work schedule flexibility. To reduce job insecurity, organizations could explicitly communicate future organizational plans. In the same vein, decision authority could be targeted by reducing hierarchical steps and increasing autonomy. Lastly, the results pertaining to agreeableness stand in contrast with those of previous studies. We assumed that workers scoring high on agreeableness tend to put themselves last and please others first. These tendencies could make them more susceptible to health issues. With that said, work environments still need workers who are agreeable and nice to be around. To prevent high levels of agreeableness leading to psychological distress, training and information workshops are recommended. Those include stress management interventions and workshops pertaining to time management and relaxation techniques.

Does salivary cortisol secretion mediate the association of work-related stressors with workers' depression?

PURPOSE

The purpose of this study was to verify the mediating role salivary cortisol intensity plays between work organization conditions and depression. This study simultaneously considered psychological and physiological (salivary cortisol) stress indicators on workers' depression in a single model.

METHODS

We relied on cluster sampling of 341 workers in 34 Quebec establishments. Five saliva samples (on awakening, 30 min after awakening, at 2:00 p.m., 4:00 p.m., and bedtime) were collected per day. The weekly collection period spanned a period of 3 days (1 day off and 2 work days). We evaluated the main effects of work organization conditions on salivary cortisol intensity and depression, as well as the mediation effect of salivary cortisol intensity between work organization conditions and depression. To adjust for design effects, the direct and indirect (mediation) associations between the variables were evaluated while accounting for the non-independence of the data.

RESULTS

Skill utilization and job insecurity were associated with salivary cortisol intensity, while psychological demands and job insecurity were associated with higher depression levels. Work-related variables were not found to have an indirect effect on depression via worker's salivary cortisol (AUC) intensity.

CONCLUSION

Work-related stressors examined in this study did not indirectly affect worker's depression levels. Additional studies are necessary to be able to identify all work-related stressors that could potentially increase worker's depression levels through salivary cortisol.

Does Depression Mediate the Effect of Work Organization Conditions on Job Performance?

OBJECTIVE

The present study proposes to shed light on the impact of workers' depression on their work performance.

METHODS

We implemented a path analyses adjusted for design effects resulting from cluster sampling using MPlus software on a sample of 1957 workers. These analyses allowed us to evaluate direct and indirect effects (mediation) while taking into account the nonindependence of observations due to cluster sampling (workers nested in their workplace).

RESULTS

Results indicate that three indirect associations were found to be significant. Psychological demands, work schedule, and job insecurity were indirectly associated with lower levels of professional efficacy/job performance because of their positive associations with depression.

CONCLUSIONS

The results obtained suggest that interventions targeting specific work organization conditions could be warranted.
