Sexual Minority Identity Development: Latent Profiles of Developmental Milestones in a National Probability Sample.

ABSTRACT

Sexual identity development milestones mark the ages at which sexual minority people first experience key developmental events including same-sex attraction, self-realization of a sexual minority identity, same-sex sexual behavior and romantic relationships, and sexual identity disclosure. Most studies of milestones use variable-centered, rather than person-centered approaches, potentially obscuring diversity in patterns across milestones. Using data from The Generations Study, the first national probability sample of White, Black, and Latinx sexual minority adults in the United States (n = 1,492), we examined variability in milestone timing and patterning using a latent profile analysis approach. We identified four distinct profiles, characterized by variability in milestone mean ages, pacing, and sequences an early adolescence profile (22.9%), a middle adolescence profile (33.6%), a late adolescence profile (27.6%), and an adulthood profile (15.9%). Profiles were demographically distinct, varying by birth cohort, sexual identity, race/ethnicity, gender identity, and childhood gender nonconformity. Results suggest developmental and demographic diversity in the emergence of sexual identity development across the life course, with implications for sexual minority health and thriving.
