Psychological factors and their relative importance in occupational burnout among healthcare workers

To quantify the relative contributions of internal and external psychological variables to occupational burnout among healthcare workers, providing a quantitative basis for formulating precise organizational intervention strategies. A cross-sectional survey was conducted among 417 healthcare workers from 3 hospitals. Dominance analysis was employed to calculate the relative importance of perceived stress, work-family conflict, resilience, psychological distress, and social support in predicting occupational burnout. Dominance analysis showed that, among psychological demands, perceived stress (38.12%) and work-family conflict (23.73%) had the largest relative explanatory contributions to occupational burnout, while psychological distress contributed 14.80%. Among psychological resources, resilience accounted for 15.95% of the relative importance, and social support accounted for 7.40%. Burnout prevention strategies for healthcare workers may benefit from addressing perceived stress and work-family conflict, while also considering resilience and social support as relevant psychological resources.
