Physical and Sexual Victimization Class Membership and Alcohol Misuse and Consequences among Sexual Minority and Heterosexual Female Youth.

Objective: Evidence demonstrates sexual orientation disparities in physical and sexual victimization and alcohol misuse and consequences among female youth; however, most extant research has used variable-centered approaches. The current study used latent class analysis (LCA), a person-centered approach, to: (1) model female youths' physical and sexual victimization; (2) examine sexual orientation disparities in physical and sexual victimization latent class membership; (3) and use physical and sexual victimization latent class membership to predict female youths' engagement in alcohol misuse and related consequences. Method: Participants were 7,185 youth assigned female sex at birth (77.0% heterosexual, 12.8% bisexual, 2.3% gay or lesbian; 46.8% racial minority) in grades 9 - 12 who completed the 2017 Youth Risk Behavior Survey - a school-based, cross-sectional survey.
Results: LCA uncovered four classes: (1) "Poly-Victimization Class," (2) "No Victimization Class," (3) "Past-Year Sexual Victimization Class," and (4) "Lifetime Rape Class." Sexual orientation emerged as a significant predictor of class membership. Latent classes 3 and 4 were uniquely associated with alcohol misuse and consequences (i.e., binge drinking, riding with a drinking driver, and drinking and driving) among female youth. Conclusions: Our findings help to elucidate the patterns of physical and sexual victimization regarding timeline, tactic used, and context among female youth; sexual orientation disparities in latent class membership; and alcohol misuse correlates of class membership. Prevention efforts aimed at reducing physical and sexual victimization may ultimately reduce female youths' risk of binge drinking, riding with drinking drivers, and drinking and driving.
