This study aims to qualitatively examine work-family enrichment resources for female nurses raising preschool children (hereafter, parent nurses). Work-family enrichment is the extent to which an individual's experiences in one role improve quality of life in another. This relationship can be bidirectional; work-to-family enrichment occurs when work experiences improve the quality of familial roles, and family-to-work enrichment occurs when family experiences improve the quality of work.Method: Participants were 16 parent nurses working in hospitals accredited by Japan Council for Quality Health Care. Semi-structured interviews were used to collect data on participants' workfamily enrichment resources. Data were analyzed qualitatively and inductively.Results: The work-to-family enrichment resources were classified into six categories: "care capability," "ability to lead," "efficiency," "emotional fulfillment," "cultivation of sociality," and "economic stability." The family-to-work resources were classified into another six categories: "empathy," "receptiveness," "expansion of one's horizon," "coordination ability," "help-seeking behavior," and "emotional fulfillment."Conclusion: All participants had gained resources from their work experiences that improved their family roles, as well as resources gained through experiences in their familial roles that improved their work quality. The findings suggest that the resources obtained from each role interacted with each other, and that the acquisition of one resource triggered the acquisition of others.
