Jung: Influence of Head Nurses' Ethical Leadership on Job Satisfaction among Staff Nurses: Mediating Effect of Affective Commitment



This study was conducted to identify the mediating effect of affective commitment on the relationship between ethical leadership and job satisfaction.


Participants were 216 nurses drawn from three general hospitals in C city. Data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and multiple regression.


The findings from multiple regression were as follows. First, people orientation, ethical guidance of ethical leadership factors showed significant positive effects on affective commitment. Second, people orientation, ethical guidance of ethical leadership factors showed significant positive effects on job satisfaction. Finally, when ethical leadership factors and affective commitment were entered into the regression model at the same time, ethical leadership factors showed no significant effects on job satisfaction, however, affective commitment showed a significant effect and so affective commitment had a mediating effect between ethical leadership and job satisfaction.


Results of this study indicate that affective commitment with an effect on the relationship between ethical leadership and job satisfaction plays a full mediating role. Thus, developing ethical leadership training programs for head nurses would likely increase the affective commitment and job satisfaction of staff nurses.
