Objective: Female caregivers often reduce time spent at work to care for aging family members, which precipitates financial hardship and other adverse outcomes. Little is known about psychosocial correlates of labor force participation (LFP) among female caregivers. The theory of planned behavior posits that social norms, attitudes, and perceived control predict intentions and volitional behaviors, but also that the compelling influence of situational variables undermines enactment of behaviors consistent with one’s intentions. The objective of this study was to employ the theory of planned behavior to examine how psychosocial characteristics predict willingness to reduce LFP among prospective caregivers and actual LFP reduction among active caregivers. Methods: Subsamples of 165 female prospective caregivers and 97 active female caregivers responded to a survey assessing filial beliefs and LFP. Results: Filial obligation and caregiver preparedness predicted intentions to reduce LFP among prospective caregivers, but did not predict actual reduction in LFP in active caregivers. Weekly care demands exceeding 20 hours emerged as the sole correlate of LFP among active caregivers. Conclusions: Domains of the theory of planned behavior predict LFP intentions, but LFP decisions are subject to external pressures, specifically, time demands of the caregiving relationship. Prospective caregivers may benefit from proactive interventions aimed at reducing conflict between situational demands and filial beliefs.
