Reliability And Validity Of The Japanese Version Of The Survey Work-Home Interaction - Nijmegen, The Swing (Swing-J)

This study sought to validate the Japanese version of the Survey Work-Home Interaction - NijmeGen, the SWING, which assesses multi-dimensional work-family interaction by differentiating between the direction and quality of influence. We translated the SWING into the Japanese language, the SWING-J. A back-translation procedure confirmed that the translation was appropriate. A total of 2701 dual-earner parents with preschool children (1193 men and 1508 women) were surveyed. The complete questionnaire included the SWING-J, job and family domain variables, and well-being indicators. The reliability and factorial and convergent validity of the used measures were examined. As the results, four dimensions (i.e. work-to-family negative spillover, family-to-work negative spillover, work-to-family positive spillover and family-to-work positive spillover) were determined by an exploratory factor analysis. A series of confirmatory factor analyses suggested that the hypothesized four-factor model provided a reasonably good fit to the data. Convergent validity was generally supported by the expected correlations of work-family spillovers with the possible predictors and consequences. Cronbach's alpha coefficients of the four subscales of the SWING-J were satisfactory (0.75-0.86). The present study confirmed that the Japanese version of the SWING is an adequate tool to measure positive and negative spillover between working life and family life among Japanese workers.
