Based on Greenhaus and Powell's (2006) theory of work-family enrichment and the job demands-resources (JD-R) model, this article proposes a model outlining the differential impact of specific social resources (supervisor support and family support) on specific types of affect (job satisfaction and family satisfaction respectively), which, in turn, influences work-to-family enrichment and family-to-work enrichment, respectively. A sample of 287 Chinese workers completed questionnaires in a three-wave longitudinal survey. The model was tested with structural equation modeling techniques. The results showed that job satisfaction at Time 2 partially mediated the relationship between Time 1 supervisor support and Time 3 work-to-family enrichment; whereas family satisfaction at Time 2 partially mediated the relationship between Time 1 family support and Time 3 family-to-work enrichment. Implications for future research and practice are discussed.
