The Anal Sex Stigma Scales: A New Measure of Sexual Stigma Among Cisgender Men Who have Sex with Men.

We conducted a series of studies to validate a new scale of stigma toward anal sex, culturally tailored to cisgender men who have sex with men (MSM). In Study 1 we conducted in-depth interviews (N = 35) to generate items. In Study 2, we reduced the item pool through an online survey (N = 268), testing scale performance, dimensionality, and convergent and discriminant validity. For Study 3, we recruited another online sample (N = 1605), randomized to exploratory or confirmatory factor analyses to finalize item reduction, then assessed validity among sexually active MSM (n = 1263). Final subscales encompassed self-stigma (6 items, Cronbach's α = .72), provider stigma (5 items, Cronbach's α = .79), and omission of information (6 items, Cronbach's α = .73; full 3-factor scale = .80). We developed a 17-item measure, grounded in the lived experience of cisgender MSM. Future work should examine associations with health-seeking behavior.
