Effort-reward imbalance and burnout among humanitarian aid workers

Objectives: This study examined stress-related working conditions – defined in terms of effort-reward imbalance (ERI) – and its association with burnout among a large, international sample of humanitarian aid workers. Methods: Descriptive statistics were applied on crosssectional survey data (N=1,980) to profile ERI and burnout and Pearson’s χ 2 tests used to characterize associated socio- and occupational-demographic factors. Associations between ERI and burnout were established using binary logistic regression to generate odds ratios and 95% confidence intervals adjusted for potential confounding variables. Results: For high emotional exhaustion, the prevalence rate was 36% for women and 27% for men; high depersonalisation, 9% and 10%; and low personal achievement, 47% and 31%. Intermediate and high ERI was associated with significantly increased odds of high emotional exhaustion, with mixed findings for depersonalisation and personal achievement. Conclusions: The ERI model was supported as a useful framework for investigating occupational correlates of burnout
