Treating homeless clients with severe mental illness and substance use disorders: costs and outcomes.

This study compared the costs and outcomes associated with three treatment programs that served 149 individuals with dual disorders (i.e., individuals with co-occurring severe mental illness and substance use disorders) who were homeless at baseline.

Impact of assertive community treatment and client characteristics on criminal justice outcomes in dual disorder homeless individuals.

Background: People with severe mental illness and substance use disorders (dual disorder) often have considerable contact with the criminal justice system.

Aims: To test the effects of client characteristics on six criminal justice outcomes among homeless (at intake) people with mental illness and substance misuse disorders.

Methods: The sample was of participants in a randomized controlled trial comparing standard treatment, assertive community treatment (ACT) and integrated treatment (IT).

Generalizability of brief psychiatric rating scale prototypical profiles and their use in evaluating treatment outcomes.

The generalizability of previously isolated prototypical profiles of the Brief Psychiatric Rating Scale (BPRS) was examined in a sample of homeless individuals with both severe mental illness and substance-use problems who were part of a 24-month study that evaluated the effectiveness of various treatment interventions. These prototypical profiles (depressed, actively psychotic, and withdrawn) did generalize to the new sample, with a 59.4% coverage rate.

A confirmatory factor analysis of the Brief Psychiatric Rating Scale in a homeless sample.

This study used a confirmatory factor analysis procedure, the Oblique Multiple Group Method (OMG), with the Brief Psychiatric Rating Scale (BPRS) on a sample of homeless individuals who had both a severe mental illness and a substance use disorder. The hypothesized five-factor model of Guy (1976) accounted for 93% of the possible variance, and all the appropriate scales had their highest loading on their respective hypothesized factor. In addition, the Guy model accounted for more variance than did an alternative model.

Prevalence of human immunodeficiency virus, hepatitis B, and hepatitis C among homeless persons with co-occurring severe mental illness and substance use disorders.

This study was undertaken to determine the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) among homeless persons with co-occurring severe mental illness (SMI) and substance use disorders and to determine associated risk factors. As part of a longitudinal study of the effectiveness of integrated treatment for homeless persons with SMI and substance abuse or dependence, serological testing was performed to ascertain the prevalence of HIV, HBV, and HCV. At baseline, 6.
