Assessing HIV/AIDS stigma in south India: validation and abridgement of the Berger HIV Stigma scale

HIV-related stigma has been associated with depression, poor adherence, and nondisclosure of HIV-positive status, all of which can lead to increased transmission of HIV and poorer health outcomes for HIV-infected individuals. The Berger HIV Stigma scale has been used in multiple settings but never adapted and validated in India, home to the world's second largest HIV-infected population. We assessed the reliability and validity of a Tamil translation of the original 40-item scale, and conducted confirmatory and exploratory factor analyses to assess cultural appropriateness and abbreviate the scale. Reliability and validity were high (alpha = 0.91; test-retest reliability ICC = 0.89). Exploratory and confirmatory factor analysis resulted in an abridged 25-item version of the scale that possessed better psychometric properties than the 40-item version. This culturally validated, abridged HIV-Stigma scale can be used in busy clinical settings to identify individuals in need of psychosocial support and assess post-intervention changes in stigma in Southern India.
