OBJECTIVE 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. METHOD 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 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. CONCLUSIONS 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.

比较三种物质使用干预措施对治疗前有无无家可归经历的青少年的有效性。

目标 许多接受药物滥用治疗的青少年和年轻人都曾经历过无家可归或面临无家可归的风险。与稳定住所的青年相比，特定治疗方法对无家可归青年 (YEH) 是否更有效尚不清楚。本研究比较了青少年社区强化方法、动机增强疗法结合认知行为疗法 (MET/CBT) 和常规治疗 (TAU) 对这两组的有效性。进一步的亚组差异按年龄、性别、性和性别少数地位进行了调查。METHOD YEH (n = 855) 和匹配的稳定住所青年样本 (n = 855) 来自全球个人需求评估，这是一个全国性的药物滥用治疗数据集。多组潜在变化评分模型用于检查基线、3 个月、6 个月和 12 个月随访时物质使用频率的变化和相关问题。结果 结果表明，所有干预组在治疗期间的物质使用频率和问题均显着下降。TAU 组在治疗期间物质使用问题下降幅度最大，治疗后频率下降幅度最大。与稳定住所的青年相比，YEH 进入治疗时有更多的物质使用和问题，并且仅在 MET/CBT 组中物质使用下降幅度更大。年龄和性别也发现了其他差异。结论 总的来说，所有三种物质使用干预措施似乎都能有效减少物质使用和相关问题。TAU 和 MET/CBT 在治疗环境中对 YEH 可能特别有效。讨论了对未来研究和实践的影响。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
