Racial Differences in the Effect of Stress on Health and the Moderating Role of Perceived Social Support

Objective: The current study examined racial differences in the relationship between late-life stress and health functioning and the moderating role of perceived social support (PSS) in older adults. Method: A biracial sample of community-dwelling older adults (65+) from the first two waves of the Duke University's Established Populations for Epidemiologic Studies of the Elderly (EPESE; N = 2,952) was analyzed. Baseline levels of PSS and stress were obtained. Health status was assessed at baseline and follow-up. Results: Analyses revealed a positive effect of PSS on health functioning. There was a three-way interaction among race, stress, and PSS on health functioning. Probing the interaction, for Caucasians, PSS was beneficial at low stress, but not high stress. For African Americans, PSS had a positive effect regardless of stress level. Discussion: PSS is an important protective factor for preserving positive health in late-life; however, benefits may differ by race and intensity of stressor.
