Family caregivers provide long-term care to their chronically ill loved ones and as a consequence they experience physical, relational and financial problems. This study investigates how long-term family caregivers rank 12 motives for caregiving. Motives are derived from the views of four philosophical anthropologists and are related to self-reported stress and joy and to several different background characteristics of respondents. Motives that focus on feelings concerning the relationship between caregiver and care recipient are more popular as a first choice than motives stemming from feelings of obligation or a general feeling of happiness and are also more popular than more self-directed motives. An analysis of full ranking data shows that two groups can be distinguished, one group of family caregivers with mixed motives and one group of family caregivers with motives that focus on reciprocal mutually equal relationships. The latter are mainly women taking care for a partner or a child, the former report high levels of stress. Implications for intervention programmes and health policy are being discussed.
