For most treatment-seeking patients with severe Alcohol Use Disorder (AUD), abstinence is the clinically indicated goal. Existing AUD motivation scales are non-specific about treatment consumption goals, which limit their effectiveness. Desires and mental imagery are relevant in the motivation for AUD treatment engagement. The Motivational Thought Frequency Scale for an abstinence goal (MTF-A) was adapted from the MTF for controlled drinking (MTF-CD). This study psychometrically evaluated the MTF-A in an alcohol-dependent sample engaged in treatment with a goal of abstinence. To enhance the clinical utility of the scale, a secondary aim was to evaluate a psychometrically equivalent short version of the MTF-A.
A sample N of 329 treatment-seeking patients with AUD (mean age of 44.44 years, SD = 11.89 years, 72% male) who were undertaking a cognitive behavioral treatment (CBT) program for abstinence completed the Motivational Thought Frequency Scale for Abstinence (MTF-A) and the Severity of Alcohol Dependence Questionnaire (SADQ). The MTF-A measured motivation for abstinence through four factors: intensity, self-efficacy imagery, incentives imagery, and availability. Confirmatory factor analyses (CFAs) were conducted to examine factor structure and model fit. Cronbach's alpha assessed internal consistency. Predictive validity was determined by logistic regression predicting first-session treatment non-attendance and alcohol consumption between baseline assessment and commencement of treatment, controlling for potential confounds.
A four-factor structure provided the best fit for the MTF-A, compared with one- and three-factor models. A shortened 9-item MTF-A scale (S-MTF-A) provided better fit than the 13-item MTF-A scale. Both MTF-A and S-MTF-A displayed good internal consistency. Although both MTF-A and S-MTF-A successfully predicted first-session treatment non-attendance, neither predicted alcohol consumption between the baseline assessment and commencement of treatment.
The model fit of the four-factor, 9-item S-MTF-A was superior to the original 13-item MTF-A. Both scales were predictive of participation of AUD treatment. Desires and mental imagery play an important role in AUD treatment motivation.
对于大多数寻求治疗的重度酒精使用障碍（AUD）患者来说，戒断是临床推荐的目标。现有的 AUD 动机量表对治疗消费目标不够具体，限制了其有效性。欲望和心理意象与 AUD 治疗参与的动机有关。为了戒断目标而改编的动机思维频率量表（MTF-A）是从控制饮酒的 MTF-CD 改编而来的。本研究在接受以戒断为目标的认知行为治疗的酒精依赖患者样本中对 MTF-A 进行了心理测量评估。为了增强量表的临床实用性，第二个目标是评估 MTF-A 的心理测量等效短版。
一个样本量为 329 名寻求治疗的 AUD 患者（平均年龄 44.44 岁，标准差 11.89 岁，72%为男性），他们正在接受认知行为治疗（CBT）计划以戒除酒精，完成了《动机思维频率量表（MTF-A）》和《酒精依赖严重程度问卷（SADQ）》。MTF-A 通过四个因素来衡量戒断的动机：强度、自我效能意象、激励意象和可得性。进行验证性因素分析（CFAs）以检验因素结构和模型拟合度。克朗巴赫α评估内部一致性。通过逻辑回归预测首次治疗时的治疗不参与和基线评估与治疗开始之间的酒精消耗，控制潜在混杂因素，确定预测效度。
与单因素和三因素模型相比，四因素结构为 MTF-A 提供了最佳拟合。一个缩短的 9 项 MTF-A 量表（S-MTF-A）比 13 项 MTF-A 量表提供了更好的拟合。MTF-A 和 S-MTF-A 都显示出良好的内部一致性。尽管 MTF-A 和 S-MTF-A 都成功预测了首次治疗时的治疗不参与，但都未能预测基线评估与治疗开始之间的酒精消耗。
四因素、9 项 S-MTF-A 的模型拟合优于原始的 13 项 MTF-A。两个量表都能预测 AUD 治疗的参与。欲望和心理意象在 AUD 治疗动机中起着重要作用。
