Validation of the Japanese Version of the Multidimensional Measure of Family Supportive Supervisor Behaviors (FSSB-J)

The aim of the current study was to validate the Japanese version of the family supportive supervisor behaviors (FSSB-J) measure. FSSB is conceptualized as a multidimensional, superordinate construct constituted of four dimensions: emotional support, instrumental support, role modeling behaviors, and creative work-family management. The Japanese translated and back-translated FSSB-J questionnaire was administered to 1,670 men and women aged 20-59 years who were registered with a Japanese online survey company in November 2017. Confirmatory factor analyses were performed to evaluate the factorial validity of the FSSB-J. Cross-time measurement invariance was tested using multi-group confirmatory factor analyses. Construct validity was assessed with the potential consequences of FSSB (e.g., work-family spillover, work engagement, intention to leave, job satisfaction, and psychological distress) and convergent validity was assessed using similar concepts (e.g., organizational justice and social support). Internal consistency and test-retest reliability were examined to evaluate the reliability of the four dimensions of the FSSB. A series of confirmatory factor analyses using the multiple-group method revealed that the four-factor model fitted the data best. The latent factor structure demonstrated configural, metric, and scalar invariance across time. Construct and convergent validity were generally in line with expectations. Cronbach's α coefficient and test-retest reliability were sufficient for each of the four dimensions of the FSSB. This study suggests that FSSB-J is an adequate measure of FSSB in the Japanese context.
