- 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, t = −4.654, p =.001), with variations across different stigma levels (β = −5.844, t = −4.003, p =.001). Social support was significantly and positively associated with self-efficacy at lower HIV stigma levels (β = 7.440, t = 3.887, p =.001), in contrast to higher levels (β = −2.825, t = 1.400, p =.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. Plain Language Summary: The relationship between perceived social support and antiretroviral therapy adherence self-efficacy among adult PLHIV in South Africa: The influence of HIV stigma. People living with HIV face unique challenges, such as HIV stigma, which impact their ability to adhere to antiretroviral therapy (ART). This study examined how HIV stigma and perceived social support affect the ART adherence self-efficacy of adults living with HIV in South Africa. This survey involved 201 participants who were selected by using time location sampling at a health facility in Durban, South Africa. The study found that HIV stigma had a significant and negative impact on self-efficacy (β = −7.860, t = −4.654, p =.001), with variations depending on the level of stigma (β = −5.844, t = −4.003, p =.001). On the other hand, social support had a significant and positive impact on self-efficacy at lower levels of HIV stigma (β = 7.440, t = 3.887, p =.001), but this effect weakened at higher levels of stigma (β = −2.825, t = 1.400, p =.163). Social support plays an important role in influencing self-efficacy, especially when HIV stigma is lower. However, the significant impact of social support diminishes as HIV stigma becomes more intense.
