Sex differences in poly-victimization among youth experiencing homelessness prior to substance use treatment

Abstract

BackgroundPoly-victimization is common among youth experiencing homelessness (YEH) and youth in substance use treatment. To date, studies have not examined poly-victimization among these two intersecting populations. ObjectiveTo examine heterogeneity in lifetime victimization experiences among youth reporting homelessness at substance use treatment entry; identify demographic predictors of victimization class membership; and associations between victimization and clinical characteristics at treatment intake. Participants and setting1270 adolescents and young adults reporting past 90-day homelessness in a nationwide substance use treatment data set. MethodsLatent Class Analysis (LCA) and logistic regression were used to examine heterogeneity in poly-victimization experiences, and associations with demographics and clinical characteristics for males and females. ResultsFour victimization classes emerged for males, and five victimization classes emerged for females. The prevalence of victimization and trauma characteristics were higher for females, except physical victimization, which was higher for males. Age, race/ethnicity, and sexual minority status were related to poly-victimization class membership, but not consistently across classes. Compared to low or single victimization classes, youth in the poly-victimization class had higher odds of post-traumatic stress disorder, major depressive disorder, and exchange sex (among females); Poly-victimization class membership was not associated with duration of recent homelessness or substance use disorder diagnoses, when compared to low/less complex victimization. ConclusionHigh rates of lifetime victimization were found for YEH in substance use treatment, with rates generally higher among females. Trauma-informed interventions are needed to address complex victimization experiences and poor mental health among unstably housed youth in treatment.
