  1. Models are linear mixed effects models assessing change in outcomes over each month during the 12-month period following study enrollment. All models are adjusted for Veteran age, year of move-in to HUD-VASH, Veteran need for treatment for a medical problem; employment status and housing status at time of assessment except for supplemental analysis model of alcohol use, which is not adjusted for any covariates due to convergence failure when including covariates
