This study examines whether the death of a close friend is associated with changes in depressive symptoms among older adults and whether this association varies by baseline social support and social contact.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data come from the Wisconsin Longitudinal Study. Analyses focus on 3,448 respondents observed at two waves when respondents were in their mid-60s and early 70s. Two-wave individual fixed-effects models estimate within-person changes in depressive symptoms following the recent death of a close friend, net of time-varying covariates. Moderation analyses test whether associations differ by baseline levels of perceived social support and social contact.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>On average, recent close friend death is not associated with changes in depressive symptoms. However, significant heterogeneity emerges by social context. Among respondents with low baseline social support, recent close friend death is associated with substantial increases in depressive symptoms, whereas no detectable effects are observed among those with moderate or high support. A similar pattern is observed for social contact: adverse mental health effects of friend death are concentrated among individuals with infrequent social contact.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings suggest that close friend death does not uniformly affect mental health in later life but poses significant risks for socially vulnerable individuals. Results underscore the importance of social resources in shaping responses to non-kin bereavement and highlight the need to move beyond average effects when assessing the mental health consequences of social loss in aging populations.<\/jats:p>\n
