Abstract

Background: People living with human immune deficiency virus (PLHIV) grapple with distinct challenges, including HIV stigma which affects their antiretroviral therapy (ART) adherence self-efficacy. This study investigates the interaction of HIV stigma and perceived social support on ART adherence self-efficacy among adult PLHIV in South Africa.

Methods: This study utilized a cross-sectional design that involved 201 participants selected using time location sampling at a tertiary health facility in Durban.

Results: HIV stigma was significantly and negatively associated with self-efficacy (β = -7.860, = -4.654, = .001), with variations across different stigma levels (β = -5.844, = -4.003, = .001). Social support was significantly and positively associated with self-efficacy at lower HIV stigma levels (β = 7.440, = 3.887, = .001), in contrast to higher levels (β = -2.825, = 1.400, = .163).

Conclusion: Social support significantly influences ART adherence self-efficacy, particularly at lower levels of HIV stigma, but the effect of support weakens as stigma intensifies.
