HIV-positive adults live longer in the wake of highly active antiretroviral therapy (HAART) (Lui et al., 2006). However, adherence to HAART programs averages 60 70% for people living with HIV/AIDS (PLWH; Simoni et al., 2006), a rate too low for the regimen to be effective (Bonttonari et al. 2010). Positive styles of coping (Jia et al. 2004) and social support (Bontempi et al., 2004) are associated with improved medication adherence, while stress is associated with decreased adherence (Bottonari et al., 2010). We hypothesize that social support, stress and coping collectively explain a significant amount of variance in adherence to HAART among PLWH. Using the Multidimensional Scale of Perceived Social Support ( = .92), Perceived Stress Scale ( = .84), and the Brief Cope measures (a = .64), we collected data from 173 HIV-positive participants in the Dallas/Fort Worth area. We conducted a hierarchical regression analysis to test our hypothesis. . Our model suggests that family support (β =-.29, t=-3.23, p<.01), support from friends (β =.25, t=2.74, p<.01), use of instrumental support (β =-.23, t=-2.66, p<.01) and stress (β =-.22, t=-2.72, p<.01) all contribute significantly to adherence [adj. R =.18, F(13, 160) = 3.93, p<.01]. Our findings suggest nuanced interactive relationships between medication adherence and family social support, support from friends, stress and coping styles. These, variables should be incorporated into public health programs addressing medication adherence for PLWH.
