This application is based on the premise that probationers and parolees must have access to stable, drug free housing to reduce HIV risk, access needed services and avoid rearrests and reincarceration. Drug free housing at the Sober Living Network (SLN) in California will be studied as a way to provide a positive living environment for probationers and parolees. The houses use a sober living house (SLH) model of recovery that includes a communal recovery environment, abstinence from drugs and alcohol, peer support, and encouragement to attend self-help groups such as Alcoholics Anonymous. Preliminary data based on a sample of 300 individuals entering 20 SLHs in California showed resident improvement in a variety of areas, including drug and alcohol use, employment, psychiatric symptoms, and arrests (Polcin et al., 2010). Although residents referred from parole and probation systems had substance use reductions that were comparable to voluntary residents, they had had far more problems maintaining employment, higher rates of arrest and incarceration, and lower attendance at self- help groups (Polcin, et al., 2010). Thirty seven percent had been rearrested at 6 month follow-up and 0ne reason may be that probationers and parolees received only 35% of the services that they felt they needed to succeed. Although over half met DSM IV criteria for methamphetamine dependence during the last year, a very high risk group for HIV, we did not assess HIV outcomes.
