Family-to-work spillover and appraisals of caregiving by employed women caring for their elderly parents in Japan.

We examined the differences in family-to-work spillover between employed women who did and did not have caregiving responsibilities for elderly parents and the relationship between family-to-work spillover and negative and positive appraisals of caregiving using moderation analysis. A cross-sectional survey was conducted with middle-aged employed women (age ≥40 years) from four large companies. Negative and positive family-to-work spillover (FWNS and FWPS, respectively) and negative and positive appraisals of caregiving were measured. Data from 386 non-caregivers and 82 caregivers were analyzed using Fisher's exact tests, Welch's t-tests, and hierarchical multiple regression. Results showed that FWNS was higher in caregivers than in non-caregivers, while there was no significant difference in FWPS. Caregiver "fulfillment from the caregiving role" (a subscale of positive appraisal) buffered the effects of caregiver "feelings of social restriction" (a subscale of negative appraisal) on FWNS. On the other hand, caregiver "commitment to caregiving tasks" (another positive subscale) intensified the effects of "feelings of social restriction" on FWNS. However, there was no relationship between negative and positive appraisals of caregiving and FWPS. These findings suggest that both negative and positive appraisals of caregiving are important contributors to FWNS among employed women caring for their parents.
