Past research among U.S. correctional staff has found that work–family conflict has negative outcomes such as decreasing job satisfaction, decreasing organizational commitment, and increasing job stress. Little empirical research has addressed the association of the specific types of work–family conflict with job involvement. The present study contributes to the literature by separately analyzing the relationship of the four specific major types of work–family conflict (time-based conflict, strain-based conflict, behavior-based conflict, and family-on-work conflict) with job involvement among surveyed staff at two Chinese prisons. Job involvement varied by the type of work–family conflict. Specifically, time-based conflict and strain-based conflict had nonsignificant association with job involvement, but behavior-based and family-based conflicts had significant negative associations.
