Predictors of 1-year housing outcomes among young adults experiencing homelessness enrolled in a rapid rehousing program.

Little is known about predictors of housing instability for young adults participating in a Boston-area rapid rehousing program over the course of 1 year. We analyzed de-identified data from young adults enrolled in a rapid rehousing program between April 2020 and March 2022. The primary outcome was housing success, defined as acquiring independent housing or securing a second-year rapid rehousing lease. Mental health, substance use, service utilization, employment, experiences of interpersonal violence, and pregnancy were collected at baseline and at 3-month intervals for 1 year. Data were analyzed for 104 young adults, comprising primarily of transition-age youth (<i>M</i> = 21.2 years) of color (86.5%) with histories of interpersonal violence exposure (51.9%) and high rates of past-month cannabis use (72.1%). Approximately two thirds (64.4%) of participants had a successful housing outcome at 1 year. A total of 24.5% (13/53) of participants who were female at birth became pregnant after being enrolled in rapid rehousing, and 100% of females at birth who became pregnant experienced interpersonal violence during rapid rehousing. Multiple logistic regression analyses identified days of cannabis use in the 30 days prior to baseline and the experience of interpersonal violence or becoming pregnant during rapid rehousing as independent predictors of unsuccessful housing outcome. Results suggest the value of integrating evidence-based approaches for substance use, relational trauma, and reproductive health into rapid rehousing programs for young adults.
