A structural equation model analysis of the effects of emotional labor and job stress on depression among nurses with long working hours: Focusing on the mediating effects of resilience and social support.
Hye-Sun Jung, Eunmi Baek
PMID 32623417WHAT IT FOUND
For nurses working over 10 hours a day, emotional labor directly increases depression.
Job stress does not directly cause depression but does so indirectly by lowering social support. Resilience also mediates the link between emotional labor and depression.
Key findings
01Emotional labor had a significant direct positive effect on depression.
02Resilience mediated the relationship between emotional labor and depression; higher emotional labor lowered resilience, which in turn raised depression.
03Social support mediated the relationship between job stress and depression; higher job stress lowered social support, which in turn raised depression.

What it does not show
The study only included nurses working in large hospitals (more than 300 beds), so results may not apply to those in smaller settings. It was cross-sectional, so it cannot prove causation, only association. Important factors like socioeconomic status and medical history were not included in the analysis. The study measured the frequency of night shifts but not the total hours worked in shifts.
Declared interests
None to report.
The easy way to misread this
Do not assume job stress is harmless because it had no direct effect on depression. It still caused depression indirectly by eroding social support.
