该研究的目的是测试跨理论模型（TTM）的结构，用于预测艾滋病毒阳性青年（16-25岁）的酒精和其他药物使用。从64名HIV阳性青年中获得了关于酒精和其他药物使用、变化阶段、自我效能、情绪困扰和社会支持的问卷和访谈。结构方程模型与标准误差确定的方法适合于小样本，表明自我效能介导的变化阶段和酒精使用之间的关系，社会支持和酒精使用。使用大麻也出现了同样的结果。这些模型预测了47%的酒精使用方差和69%的大麻使用方差。结果支持TTM，并强调了旨在提高自我效能和社会支持以减少物质使用的干预措施的潜力。
The purpose of the study was to test constructs of the Transtheoretical Model (TTM) for predicting alcohol and other drug use in HIV-positive youth (ages 16-25). Questionnaires and interviews about alcohol and other drug use, stage of change, self-efficacy, emotional distress and social support were obtained from 64 HIV-positive youth. Structural equation modeling with standard errors determined by methods appropriate to small samples, demonstrated that self-efficacy mediated the relationship between stage of change and alcohol use and between social support and alcohol use. The same pattern of results emerged for marijuana use. The models predicted 47% of the variance in alcohol use and 69% of the variance in marijuana use. Results supported the TTM and highlight the potential of interventions that seek to boost self-efficacy and social support specific to reducing substance use.
