Background The mental health of nurses is an important issue.

Aims 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.
