The Housing and Urban Development-Department of Veterans Affairs Supportive Housing (HUD-VASH) program is the largest supported housing program in the country for homeless veterans who are seeking rapid entry into permanent independent housing. This study examined factors related to how rapidly clients were housed in the early years of the program and how long they stayed in the program. Mental health, substance abuse, work/income, criminal history, and site were examined as predictors of process times. Regression analyses based on 627 HUD-VASH clients who entered the program between 1992 and 2003 showed that client characteristics were not rate-limiting factors for obtaining HUD-VASH housing; i.e., clients who had greater substance abuse problems or more extensive criminal histories did not take longer to obtain housing. The large differences associated with site of entry partly reflected a curvilinear relationship between the duration of operation of the HUD-VASH program and process times; i.e., at relatively younger and older programs, clients entered housing slightly faster than at programs in the middle range. Lastly, HUD-VASH clients whose case managers reported good therapeutic alliances stayed in the program longer. These findings have implications for the continued expansion of the HUD-VASH program.
