The study examined whether youth demographics, family factors, and maltreatment type were related to unstable housing and whether unstable housing predicted delinquency and marijuana use. Participants included 216 child welfare-affiliated adolescents (mean age = 18.2 years). Youth with more lifetime residences were more likely to experience unstable housing although Latino youth (compared to White, Black, or multiethnic/biracial) were less likely to experience unstable housing. Unstable housing was associated with subsequent delinquency. Caregiver type (parent vs. relative/unrelated caregiver) was not related to unstable housing, thus homelessness prevention programs should include youth who remain with their parents and those with non-parent caregivers.
