OBJECTIVE: Homeless persons with alcohol and other drug (AOD) disorders face multiple problems that go beyond their AOD use. As a consequence, they commonly access services in multiple sectors in addition to the AOD treatment system. This study examined the predictors of contact with agencies in the health, mental health, social welfare and criminal justice sectors by AOD status among a probability sample of homeless adults in Houston, Texas.

METHOD: Cross-sectional data were collected from a multistage random sample of 797 homeless adults (579 men), age 18 or older, who were living in shelters and on the streets of Houston in 1996. Structured face-to-face interviews provided screening diagnoses for AOD disorders, self-report data on AOD treatment use and candidate predictors of treatment use. Service use was tracked retrospectively through administrative data obtained from 10 federal, state, county and municipal agencies that provide funding for physical and mental health services and AOD treatment, as well as emergency income; we also tracked criminal justice contacts. Logistic regression analyses were stratified by AOD status.

RESULTS: Adjusting for eligibility factors, key aspects of need were significant predictors of any utilization among those without an AOD problem, but not for those with an AOD problem. For those with AOD disorders, contact with one sector was not predictive of contact with other sectors.

CONCLUSIONS: Our findings indicate that AOD disorders hinder utilization of public sector services by homeless persons. These disorders may be masking need or otherwise acting as a barrier to accessing treatment and support. (Authors)
