Changing addictive behavior is a complex process with high demands on motivation. The Transtheoretical Model of Behavior Change provides a theoretical framework for explaining and predicting behavioral change, although its predictive value for addiction is somewhat inconsistent. The aim of the present study is to extend the Transtheoretical Model of Behavior Change by investigating not only treatment motivation but also the predictive value of the type of drinking-related treatment goal. Additional predictors, such as substance-related and sociodemographic variables, are also included in analyses seeking to predict return to drinking during relapse prevention treatment for alcohol use disorder. In this observational study, 99 inpatients from a treatment center for alcohol use disorder were recruited. Treatment motivation was assessed in accordance with the Transtheoretical Model of Behavior Change, drinking-related treatment goal through a self-report questionnaire, and substance-related and sociodemographic variables via the clinic information system. Associations between the potential predictors and covariates were explored using stepwise logistic regression. During treatment, 42.6% of participants had at least one relapse. Scoring higher on the action dimension at admission ( 0.81, = .04) and being employed ( 0.37, = .02) were significant predictors of abstinence during treatment. This study confirms that treatment motivation contributes to the prediction of treatment outcome, even when controlling for other variables. In future research, the underlying mechanisms of treatment motivation should be further explored.
改变成瘾行为是一个复杂的过程，对动机的要求很高。行为改变的跨理论模型为解释和预测行为改变提供了一个理论框架，尽管它对成瘾的预测价值有些不一致。本研究的目的是通过研究治疗动机以及与饮酒相关的治疗目标类型的预测价值来扩展行为改变的跨理论模型。在寻求预测酒精使用障碍复发预防治疗期间复饮的分析中，还包括了其他预测因素，如物质相关和社会人口统计学变量。在这项观察性研究中，从一家酒精使用障碍治疗中心招募了 99 名住院患者。根据行为改变的跨理论模型评估治疗动机，通过自我报告问卷评估与饮酒相关的治疗目标，通过诊所信息系统评估物质相关和社会人口统计学变量。使用逐步逻辑回归探索潜在预测因子和协变量之间的关联。在治疗期间，42.6%的参与者至少有一次复发。入院时行动维度得分较高（0.81， =.04）和就业（0.37， =.02）是治疗期间戒酒的显著预测因子。这项研究证实，即使在控制其他变量的情况下，治疗动机也有助于预测治疗结果。在未来的研究中，应进一步探讨治疗动机的潜在机制。
