This study explored the relationship between three-component organizational/occupational commitment and organizational/occupational turnover intention, and the reciprocal relationship between organizational and occupational turnover intention with a non-recursive model in collectivist cultural settings. We selected 177 nursing staffs out of 30 hospitals in Taiwan as our sample, and structural equation modelling analysis was conducted to test our hypotheses. The results showed that normative organizational commitment negatively correlates with organizational turnover intention most strongly, and affective occupational commitment negatively correlates with occupational turnover intention most strongly. Moreover, organizational turnover intention plays a mediating role in the relationship between normative organizational commitment and occupational turnover intention, while occupational turnover intention mediates the relationship between affective occupational commitment and organizational turnover intention. In particular, the reciprocal relationship exists between organizational and occupational turnover intention. Practical implications and suggestions for future research were also discussed.
