13-Item Stigma Scale
The 13-Item Stigma Scale is a validated self-report instrument designed to measure experienced and perceived sexual behavior stigma among gay men and other men who have sex with men (MSM). Developed through extensive research across eight Sub-Saharan African countries and the United States, the scale captures multiple dimensions of stigma, including enacted, perceived, and internalized stigma, as well as stigma in healthcare and social contexts. Respondents report the frequency and intensity of discriminatory or stigmatizing experiences related to their sexual behavior or identity, making the tool particularly relevant for understanding structural and interpersonal stigma across diverse sociocultural settings. The scale is grounded in stigma theory and tailored to be cross-culturally adaptable, supporting its application in both research and public health surveillance. It has been used to quantify stigma burden among MSM and inform public health strategies targeting HIV prevention, care engagement, and stigma reduction efforts. The scale offers a standardized approach to monitoring stigma in global health research and programmatic evaluation.
