Impact of Supported Housing on Clinical Outcomes: Analysis of a Randomized Trial Using Multiple Imputation TechniqueCheng, An-Lin PhD*; Lin, Haiqun PhD*; Kasprow, Wesley PhD†‡; Rosenheck, Robert A. MD*†‡Journal of Nervous & Mental Disease: January 2007 - Volume 195 - Issue 1 - pp 83-88 doi: 10.1097/01.nmd.0000252313.49043.f2 Original Articles Abstract Author Information In 1992, the US Department of Housing and Urban Development (HUD) and the US Department of Veterans Affairs (VA) established the HUD-VA Supported Housing (HUD-VASH) Program to provide integrated clinical and housing services to homeless veterans with psychiatric and/or substance abuse disorders at 19 sites. At four sites, 460 subjects were randomly assigned to one of the three groups: (1) HUD-VASH, with both Section 8 vouchers and intensive case management; (2) case management only; and (3) standard VA care. A previous publication found HUD-VASH resulted in superior housing outcomes but yielded no benefits on clinical outcomes. Since many participants missed prescheduled visits during the follow-up period and follow-up rates were quite different across the groups, we reanalyzed these data using multiple imputation statistical methods to account for the missing observations. Significant benefits were found for HUD-VASH in drug and alcohol abuse outcomes that had not previously been identified. *Department of Epidemiology and Public Health, Yale University, New Haven, Connecticut; †Department of Psychiatry, Yale University, New Haven, Connecticut; and ‡VA Northeast Program Evaluation Center, West Haven, Connecticut.
