The effort-reward imbalance model in policing: associations with mental health and work functioning among sworn and civilian employees.

TL;DR

Effort-reward imbalance and overcommitment showed consistent associations with mental health and occupational functioning in policing, and these associations did not differ between sworn officers and civilian employees.

Key Findings

Higher effort-reward imbalance ratio was significantly associated with greater anxiety and depressive symptoms among police employees.

  • ERI ratio was associated with higher anxiety symptoms (β = 0.28) and depressive symptoms (β = 0.33)
  • These associations were found in a covariate-adjusted analytic sample of N = 558
  • The study used the 16-item short ERI questionnaire to measure effort, reward, and overcommitment
  • The ERI ratio was calculated from the effort and reward scales

Higher effort-reward imbalance ratio was associated with lower occupational functioning, including reduced work engagement and job-related self-efficacy.

  • ERI ratio was associated with lower work engagement (β = -0.27) and lower job-related self-efficacy (β = -0.16)
  • Work engagement and job-related self-efficacy were assessed using separate questionnaires
  • Associations were tested using hierarchical regression analyses
  • The analytic sample included both sworn officers and civilian employees in the Norwegian police

Overcommitment showed stronger associations with anxiety and depressive symptoms than the ERI ratio itself.

  • Overcommitment was associated with anxiety symptoms (β = 0.50) and depressive symptoms (β = 0.46)
  • These beta coefficients were notably larger than those observed for the ERI ratio (β = 0.28 for anxiety, β = 0.33 for depression)
  • Overcommitment was also inversely associated with job-related self-efficacy (β = -0.28) and work engagement (β = -0.14)
  • Overcommitment was measured as part of the 16-item short ERI questionnaire

No significant differences were found between sworn police officers and civilian employees in ERI variables, mental health outcomes, or occupational functioning.

  • Group differences were examined using analyses of covariance in the covariate-adjusted analytic sample (N = 558)
  • No significant between-group differences were observed for effort, reward, overcommitment, anxiety symptoms, depressive symptoms, work engagement, or job-related self-efficacy
  • A random sample of 4000 employees was invited to participate, with 560 completing the survey
  • The study was conducted in the Norwegian police service

Occupational role (sworn officer vs. civilian) did not moderate the associations between ERI variables and mental health or occupational functioning outcomes.

  • Interaction terms for occupational role were included in hierarchical regression analyses to test moderation
  • No significant interaction effects were found for any of the outcome variables (anxiety symptoms, depressive symptoms, work engagement, job-related self-efficacy)
  • The authors conclude that 'ERI processes operate similarly across occupational categories within a highly regulated welfare-state context'
  • This finding suggests that previously limited research focus on civilian police employees may not reflect meaningful differences in ERI-related stress processes

The study had a low response rate, with 560 out of 4000 invited employees participating.

  • A random sample of 4000 employees was invited to complete an online survey
  • 560 employees participated, representing a response rate of 14%
  • The covariate-adjusted analytic sample was N = 558
  • The cross-sectional design limits causal inference

What This Means

This research suggests that the stress experienced by police workers when their efforts at work are not adequately rewarded — a concept called effort-reward imbalance — is meaningfully linked to poorer mental health and reduced ability to function effectively at work. Specifically, police employees who felt they were putting in more effort than they were getting back in terms of pay, recognition, or job security reported more anxiety, more depression, less enthusiasm for their work, and lower confidence in their own job abilities. A related factor called 'overcommitment' — a tendency to become excessively absorbed in work and unable to disengage — showed even stronger links to anxiety and depression than the imbalance itself. Importantly, this research suggests that these patterns were essentially the same for both sworn police officers (those with law enforcement powers) and civilian employees (administrative and support staff). Contrary to assumptions that might lead researchers to focus primarily on officers, civilian staff experienced similar levels of work stress and similar relationships between that stress and their mental health. This finding challenges the existing research gap in which civilians in policing have largely been overlooked. The study was conducted in the Norwegian police service, which operates within a strong welfare-state context with significant labor protections, and had a relatively low response rate of about 14%, which may limit how broadly the findings can be generalized. Nevertheless, the results support the broader Effort-Reward Imbalance model as applicable to policing environments, and suggest that organizational efforts to address work stress — such as improving recognition, career opportunities, and reward systems — may benefit all police employees, not just sworn officers.
