RESUMO
AIMS: We conducted a cross-sectional study on healthcare workers from the University Hospital in Clermont-Ferrand. They received a self-report questionnaire consisting of the Maslach Burnout Inventory, Job Demand Control Support, Effort-Reward Imbalance model, and questions about ethical conflict in order to investigate on burnout. RESULTS: We included 1774 workers. Overinvestment was the only factor explaining the increase in emotional exhaustion, depersonalization, and the decrease in personal accomplishment. Taking into account the absence of burnout as a reference, overinvestment multiplied the risk of high burnout by 22.0 (5.10 to 94.7). CONCLUSION: Some "forgotten" occupations among healthcare workers are at risk of burnout. Overinvestment was the main factor explaining the increase in the tree dimensions of burnout. Moreover, the two main models of stress at work were highly predictive of burnout.
