Psychometric Evaluation of a Myanmar Version of the Perceived Stress Scale for People Living with HIV/AIDS.

Background and Purpose: Reliable instruments for the measurement of perceived stress in people living with HIV (PLHIV) are crucial. However, there is no Myanmar version of such an instrument. Methods: We adapted the 35-item Perceived Stress Scale for People Living with HIV/AIDS (PSSHIV) into a Myanmar version (PSSHIV-M), and 150 PLHIV completed the survey. Results: The 31-item PSSHIV-M with a five-factor structure has a Cronbach's alpha of .85 to .95. Construct validity was demonstrated for the instrument, and the findings of Rasch analysis also suggest evidence of reliability and validity. Conclusions: The psychometric properties of the 31-item PSSHIV-M with a five-factor structure support its efficacy in ascertaining how HIV perceived stress affects Myanmar PLHIV. It could also facilitate the development of stress management interventions for that population.
