Sexual and gender minority youth, especially those assigned female at birth, are at risk for intimate partner violence (IPV) due to minority stressors. With a sample of 352 sexual and gender minority youth assigned female at birth (ages 16–32), we aimed to describe IPV in this population, including the prevalence, directionality, frequency, co-occurrence, and demographic correlates of various IPV types. Rates of past-6-month IPV were high, with victimization and perpetration of minor psychological IPV most common (64–70%); followed by severe psychological, minor physical, and coercive control (21–33%); and severe physical and sexual IPV (10–15%). For cyber abuse and IPV tactics leveraging anti-sexual minority stigma, victimization (12.5% and 14.8%, respectively) was more common than perpetration (8% and 5.7%, respectively). Most IPV was bidirectional and occurred 1–2 times in 6 months, although the frequency varied considerably. Latent class analyses revealed that half of the participants reported no or minimal IPV; one-third experienced multiple forms of psychological IPV (including coercive control); and 10–15% reported psychological, physical, sexual, and cyber abuse. Racial minority youth had higher rates of most IPV types than White participants. We hope study findings will inform policies and interventions to prevent IPV among gender and sexual minority youth assigned female at birth.
