| Abstract: | Perceived social support, coping strategy, and internalized stigma have been linked with the quality of life (QOL) among people living with HIV (PLHIV). However, little is known about how these psychosocial factors interact with each other and affect QOL. This study incorporated a moderated mediation model to investigate whether coping strategy mediates the relationship between perceived social support and QOL, and to examine whether this mediating effect varies with the level of internalized stigma among PLHIV. A cross-sectional study was conducted among 599 PLHIV in Nepal. The multidimensional scale of perceived social support, World Health Organization Quality of Life-BREF, Brief COPE, and AIDS-related stigma scales were used to measure perceived social support, QOL, coping strategy, and internalized stigma, respectively. Data were analyzed using structural equation modeling, and moderated mediation analysis was conducted with multi-group approach. The relationship between perceived social support and QOL was significantly and partially mediated by problem-focused coping strategy. Internalized stigma significantly moderated the mediating effect of coping strategies on the association between perceived social support and QOL. For high internalized stigma group (total stigma score?>?2), the effects of perceived social support on QOL were indirect (β?=?1.48; 61.0% of total effects) through the mediating effect of coping strategy, especially problem-focused coping one. For low internalized stigma group (total stigma score?≤?2), problem-focused coping strategy did not significantly affect the QOL, and most of the effects of perceived social support were direct (β?=?1.24; 99.2% of total effects). Internalized stigma was found to moderate the mediating effect of problem-focused coping on the relationship between perceived social support and QOL. Enhancing the problem-focused coping and social support may be helpful to improve QOL among PLHIV reporting high stigma. |
