The aim of this study was to explore the effect of work engagement, as an intermediary variable, on the relationship between self-efficacy, and job satisfaction and affective organizational commitment as individual indicators of quality of working life (QWL). A cross-sectional correlational design was utilized assessing a convenience sample of 321 nursing staff. All participants were employed in public hospitals and had more than five months of professional experience in the same hospital. Mediation analysis was performed using path analysis and bootstrapping confidence intervals (percentile-corrected). Work engagement partially mediated the relation between self-efficacy and job satisfaction, and fully mediated the relation between self-efficacy and affective organizational commitment. Self-efficacy seems to be an important predictor of QWL in nursing staff, although its effect is partially mediated (e.g., job satisfaction) or fully mediated (e.g., affective commitment) by work engagement.
