What does this research mean for the field?

Effort-reward imbalance and overcommitment are consistently associated with poorer mental health and lower occupational functioning in police departments, with these effects operating similarly across both sworn officers and civilian employees. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

What question did this study set out to answer?

To examine associations between effort–reward imbalance variables, mental health, and occupational functioning, and to determine whether these associations vary between sworn officers and civilian personnel.

To examine associations between effort–reward imbalance variables, mental health, and occupational functioning, and to determine whether these associations vary between sworn officers and civilian personnel.
Cross-sectional survey administered to a random sample of sworn police officers and civilian employees within the Norwegian police (N = 558 in covariate-adjusted analyses, from 4,000 invited).
Assessed effort, reward, and overcommitment via the 16-item short Effort–Reward Imbalance (ERI) questionnaire, alongside standardized measures of anxiety, depression, work engagement, and job-related self-efficacy.
Evaluated group differences using analysis of covariance and analyzed associations using hierarchical regression with occupational role interaction terms.
No statistically significant differences occurred between sworn officers and civilian employees across ERI dimensions, mental health outcomes, or work functioning.
A higher ERI ratio associated with increased anxiety symptoms (β = 0.28) and depressive symptoms (β = 0.33), as well as reduced work engagement (β = −0.27) and job-related self-efficacy (β = −0.16).
Overcommitment was positively associated with anxiety (β = 0.50) and depressive symptoms (β = 0.46), and inversely associated with job-related self-efficacy (β = −0.28) and work engagement (β = −0.14), with no moderation by occupational role.
