A Longitudinal Study of IPV Victimization Among Sexual Minority Youth.

Although intimate partner violence (IPV) is highly prevalent among lesbian, gay, bisexual, and transgender (LGBT) youth, little is known regarding its developmental patterns, risk factors, or health-related consequences. We examined IPV victimization in an ethnically diverse community-based convenience sample of 248 LGBT youth (aged 16-20 at study outset) who provided six waves of data across a 5-year period. Results from multilevel models indicated high, stable rates of IPV victimization across this developmental period (ages 16-25 years) that differed between demographic groups. Overall, 45.2% of LGBT youth were physically abused and 16.9% were sexually victimized by a dating partner during the study. Odds of physical victimization were 76% higher for female than for male LGBT youth, 2.46 times higher for transgender than for cisgender youth, and 2 to 4 times higher for racial-ethnic minorities than for White youth. The prevalence of physical IPV declined with age for White youth but remained stable for racial-ethnic minorities. Odds of sexual victimization were 3.42 times higher for transgender than for cisgender youth, 75% higher for bisexual or questioning than for gay or lesbian youth, and increased more with age for male than female participants. Within-person analyses indicated that odds of physical IPV were higher at times when youth reported more sexual partners, more marijuana use, and lower social support; odds of sexual IPV were higher at times when youth reported more sexual partners and more LGBT-related victimization. In prospective analyses, sexual IPV predicted increased psychological distress; both IPV types marginally predicted increased marijuana use.
