Comparing the effectiveness of three substance use interventions for youth with and without homelessness experiences prior to treatment.

Abstract

Many adolescents and young adults receiving substance use treatment have experienced or are at risk for homelessness. It is unknown whether specific treatment approaches are more or less effective for youth experiencing homelessness (YEH) compared to stably housed youth. The present study compared the effectiveness of the Adolescent Community Reinforcement Approach, Motivational Enhancement Therapy combined with Cognitive-Behavioral Therapy (MET/CBT), and Treatment as Usual (TAU) for these two groups. Further subgroup differences were investigated by age, sex, and sexual and gender minority status. YEH (n = 855) and a matched sample of stably housed youth (n = 855) were drawn from the Global Appraisal of Individual Needs, a nationwide substance use treatment data set. Multiple-group latent change score modeling was used to examine change in substance use frequency and related problems at baseline, 3-, 6-, and 12-month follow-ups. Results indicated significant declines in substance use frequency and problems during treatment for all intervention groups. The TAU group showed the greatest declines in substance use problems during treatment and the greatest declines in frequency post-treatment. Compared to stably housed youth, YEH entered treatment with greater substance use and problems, and had greater declines in substance use in the MET/CBT group only. Other differences were found by age and sex. Overall, all three substance use interventions appear to be effective in reducing substance use and related problems. TAU and MET/CBT may be particularly effective for YEH in treatment settings. Implications for future research and practice are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
