Caregiving in the last years of life is associated with increased depression and negative health outcomes for surviving spouses, many of whom are themselves in poor health. Yet it is unclear how often spouses are caregiving alone, how they differ from supported spouses, and whether lack of support affects postbereavement outcomes. We hypothesized that spouses who were solo caregivers--that is, the only caregivers (paid or unpaid) who provided assistance with a spouse's selfcare or household activities--would experience more depression after bereavement than supported spouses would.
