Association of Condom Use Advocacy with Perceived Condom Use Among Social Network Members: The Mediating Role of Advocates' Internalized HIV Stigma and Own Condom Use.

We examined the association of HIV prevention advocacy with social network members (alters) on alter condom use behavior, and factors that may mediate and moderate this relationship, among people living with HIV (PLWH) in Uganda. Ninety PLWH completed all assessments (baseline and 5- and 8-month follow-ups). Internalized HIV stigma, HIV disclosure self-efficacy, positive living behavior (i.e., condom use), and advocacy self-efficacy were examined as mediators (at 5-month follow-up) of the association between condom use advocacy and perceived alter condom use. Individual socio-demographic and social network characteristics at baseline were examined as moderators. Among alters who received condom use advocacy in the months prior to both baseline and 5-month follow-up, 69.9% (51/73) were perceived to mostly/always use condoms at either the 5- or 8-month follow-up, which was significantly higher than the 36.4% (235/645) of alters who received none or less advocacy. Participants' internalized HIV stigma and consistent condom use mediated the association of advocacy and perceived consistent condom use among alters; the participant having any secondary education and the alter being male were associated with increased magnitude of the associations between advocacy and alter condom use. These findings highlight the importance of sustained advocacy to promote consistent condom use, and the value of anti-stigma and positive living interventions as mechanisms for enhancing effective advocacy.
