Purpose: The affective commitment of hospital staff is important for human resources management and the sustainable development of hospitals. Psychological safety is an important factor that contributes to an emotional connection to an organization among staff, yet its functional mechanism remains unclear. This study explored how psychological safety influenced affective commitment through the mediating roles of job satisfaction and job burnout.
Methods: A battery of surveys were administered to all medical staff (n = 267) in a local second-grade comprehensive hospital. The surveys included the Psychological Safety Scale, Affective Commitment Scale, Minnesota Satisfaction Questionnaire, Maslach Burnout Inventory–Human Service Survey, and Perceived Organizational Support Scale.
Results: Job satisfaction and job burnout fully mediated the relationship between psychological safety and affective commitment among hospital staff. In addition, perceived organizational support moderated the mediating path via job burnout, and the indirect effect of job burnout decreased when perceived organizational support increased.
Conclusion: Psychological safety may enhance the affective commitment of hospital staff through improving job satisfaction or reducing job burnout. Perceived organizational support may counteract the deleterious effect of job burnout on affective commitment. Effective strategies to improve affective commitment among hospital staff may require consideration of job burnout and job satisfaction.
