title: Effort-reward imbalance and depressive state in nurses.
abstract: BACKGROUND
  The mental health of nurses is an important issue.
  
  
  OBJECTIVE
  To examine relationships between effort-reward imbalance (ERI) and depression and anxiety in nurses of a Japanese general hospital.
  
  
  METHODS
  A self-report survey was conducted among 406 nurses. Work stress was measured using a Japanese version of the ERI scale. Depression and anxiety were assessed by an item of the QOL-26. Logistic regression analysis was used to determine the independent contribution of the effort-reward ratios or overcommitment to the depressive state.
  
  
  RESULTS
  Both higher effort-money ratio and higher overcommitment significantly correlated with the depressive state (OR: 2.75; 95% CI: 1.34-5.66 and OR: 1.27; 95% CI: 1.15-1.41, respectively).
  
  
  CONCLUSIONS
  These findings suggest that in addition to effort-money ratio, overcommitment at work is an especially important issue that may be able to be managed in health promotion services for nurses in general hospitals.
