Introduction: Valid and reliable instruments are crucial for measuring perceived social support among people living with HIV (PLHIV). We aimed to investigate the psychometric properties of the English version of the 19-item Medical Outcomes Study Social Support Survey (MOS-SSS) adapted for PLHIV in Myanmar. Methods: Based on a standard cross-cultural procedure, we adapted the MOS-SSS and formed a Myanmar version of the scale (MOS-SSS-M), and then tested its validity and reliability. A sample of 250 eligible PLHIV was collected from a closed Facebook group that included more than 10,000 Myanmars, most of whom were PLHIV. Results: The MOS-SSS-M achieved a Cronbach's α of 0.82-0.95. Confirmatory factor analysis revealed an acceptable fit index for the four-factor structure. Construct validity was demonstrated by significant association with self-reported HIV stigma and stress levels, and further confirmed by the findings of Rasch analysis. Conclusion: The MOS-SSS-M with a four-factor structure can be used to measure the level and categories of perceived social support among PLHIV in Myanmar.

Abstract

HIV is a highly stigmatized and stressful condition for people with HIV (PWH). As a country heavily influenced by religion, especially Buddhism, we explore how the perceived stress from HIV stigma interacts with the mediator of mindfulness on PWH in Myanmar. From January to July 2020, a sample of 248 eligible PWH was recruited by quasi-random sampling methods from a private Facebook group in Myanmar. Data on demographics, HIV stigma, mindfulness, and perceived stress were collected. The bias-corrected percentile bootstrap method was used to test multiple mediation analyses. The path from perceived HIV stigma to perceived stress (direct effect β = 0.16) and the mediating effect of mindfulness on that stress were significant (indirect effect accounts for 45.15% of total effect). The findings indicate that interventions enhancing mindfulness-based practice should be considered to reduce HIV stigma and, therefore, lower perceived stress among PWH in Myanmar.
