Data were analyzed using multiple regression analysis. The results indicated that psychological characteristics and environment taken together accounted for 32 % of the variance in family-to-work facilitation and 19 % in work-to-family facilitation. The predictor with the greatest relative influence on family- to-work facilitation was family support, whereas workload was the most important predictor of work-to-family facilitation. Moreover, work support was the second relative influence on work-to-family facilitation. The results support the importance of family and work support on work-family facilitation.
