A previous randomized trial with 224 alcohol and/or cocaine addicts who had completed an initial phase of treatment indicated that 12 weeks of telephone-based continuing care yielded higher abstinence rates over 24 months than did group counseling continuing care. The current study examined mediators of this treatment effect. Results suggested that self-help involvement during treatment and self-efficacy and commitment to abstinence 3 months after treatment mediated subsequent abstinence outcomes. These analyses controlled for substance use prior to the assessment of mediators. Conversely, there was no evidence that self-help beliefs or social support mediated the treatment effect. These results are consistent with a model in which treatment effects are first accounted for by changes in behavior, followed by changes in self-efficacy and in commitment to abstinence.
一项针对224名已完成初始治疗阶段的酒精和/或可卡因成瘾者的前期随机试验表明，与团体咨询持续护理相比，为期12周的电话持续护理在24个月内产生了更高的戒酒率。当前的研究检验了这种治疗效果的中介因素。结果表明，治疗期间的自助参与以及治疗3个月后的自我效能感和戒酒承诺介导了随后的戒酒结果。这些分析在评估中介因素之前对物质使用情况进行了控制。相反，没有证据表明自助信念或社会支持介导了治疗效果。这些结果与一个模型一致，在该模型中，治疗效果首先由行为变化来解释，随后是自我效能感和戒酒承诺的变化。
