目的：本研究测试了一个综合复发模型，该模型从人际和个体内复发模型中得出假设。据推测，特定于酒精的社会支持（支持饮酒和支持不饮酒）与饮酒结果之间的关系将部分由动机调节。方法：参与者为 158 名患有酒精使用障碍的女性，参与两项关联随机对照试验。一项试验将针对酒精使用障碍的标准个体认知行为疗法 (CBT) 与针对酒精使用障碍的女性特定 CBT 进行了比较；另一项将酒精行为夫妻疗法与混合个体 CBT 和酒精行为夫妻疗法进行了比较。措施包括衡量社会支持变量的重要人物访谈、衡量饮酒变量的时间线追踪、以及衡量动机的变革准备阶段和治疗渴望量表。结果：结构方程模型的结果表明动机在饮酒支持与饮酒频率之间的关系中发挥中介作用。基线时对饮酒有更多网络支持的个体在治疗结束时戒酒的动机较低，这预测了治疗后 6 个月内的饮酒频率。思维基线支持对 6 个月随访饮酒频率的间接影响具有统计学意义。对于不饮酒的支持与饮酒频率之间的关系，也发现了类似的模式，尽管只有轻微的显着性。在基线时不饮酒而拥有更多社交网络的个体在治疗结束时在趋势水平上有更多的动机，这反过来又预测了 6 个月的后续饮酒频率。不饮酒基线支持对 6 个月随访饮酒频率的间接影响趋于显着。结论：这项研究提供了初步证据，表明动机是戒酒特定社会支持影响治疗结果的一种机制。 （酒精药物研究杂志，71, 930-937, 2010）
Objective: This study tested an integrated relapse model drawing hypotheses from both interpersonal and intra-individual relapse models. It was hypothesized that the relationships between alcohol-specific social support (support for drinking and support for not drinking) and drinking outcomes would be partially mediated by motivation. Method: Participants were 158 women with alcohol use disorders participating in two linked randomized controlled trials. One trial compared standard individual cognitive behavioral therapy (CBT) for alcohol use disorders with female-specific CBT for alcohol use disorders; the other compared alcohol behavioral couple therapy with blended individual CBT and alcohol behavioral couple therapy. Measures included the Important People Interview to measure social-support variables, the Time-line Followback to measure drinking variables, and the Stages of Change Readiness and Treatment Eagerness Scale to measure motivation. Results: Results of structural equation modeling suggested a mediational role of motivation in the relationship between support for drinking and drinking frequency. Individuals with more network support for drinking at baseline had less motivation for abstinence at the end of treatment, which predicted drinking frequency over the 6 months after treatment. The indirect effect of baseline support for thinking on 6-month follow-up drinking frequency was statistically significant. A similar, although only marginally significant, pattern was found for the relationship between support for not drinking and drinking frequency. Individuals with more social network for not drinking at baseline had more motivation at the end of treatment at the trend level, which in turn predicted 6-month follow-up drinking frequency. The indirect effect of baseline support for not drinking on 6-month follow-up drinking frequency trended toward significance. Conclusions: This study offers preliminary evidence that motivation is one mechanism by which abstinence-specific social support affects treatment outcome. (J. Stud. Alcohol Drugs, 71, 930-937, 2010)
