[영문]Using person-environment fit theory, this article formulates a conceptual model that links work, family, and boundary-spanning demands and resources to work and family role performance and quality. Linking mechanisms include 2 dimensions of perceived work-family fit (work demands?family resources fit and family demands?work resources fit) and a global assessment of perceived work-family balance. Work, family, and boundary-spanning demands and resources are associated with the 2 dimensions of fit, which combine with boundary-spanning strategies to influence work-family balance, which in turn affects role performance and quality. The model provides a framework for clarifying and integrating previous conceptualizations, measures, and empirical research regarding perceived work-family fit and balance as linkages between the work-family interface and outcomes. The article closes with suggestions for further work.
