Motivational interviewing (MI) is an efficacious treatment for alcohol use disorders. MI is thought to enhance motivation via a combination of 2 therapeutic strategies or active ingredients: 1 relational and 1 directional. The primary aim of this study was to examine MI's hypothesized active ingredients using a dismantling design. Problem drinkers (N = 139) seeking treatment were randomized to 1 of 3 conditions: MI, relational MI without the directional elements labeled spirit-only MI (SOMI), or a nontherapy control condition and followed for 8 weeks. Those assigned to MI or SOMI received 4 sessions of treatment over 8 weeks. All participants significantly reduced their drinking by Week 8, but reductions were equivalent across conditions. The hypothesis that baseline motivation would significantly moderate condition effects on outcome was generally not supported. Failure to find support for MI's hypothesized active ingredients is discussed in the context of the strengths and limitations of the study design. (PsycINFO Database Record
动机访谈(MI)是一种有效的治疗酒精使用障碍的方法。MI 被认为通过结合两种治疗策略或有效成分来增强动机:1 种关系性和 1 种方向性。本研究的主要目的是使用分解设计来检验 MI 的假设性有效成分。寻求治疗的问题饮酒者(N = 139)被随机分配到 3 种条件之一:MI、不包含定向元素的关系 MI(仅 SOMI)或非治疗对照组,并随访 8 周。分配到 MI 或 SOMI 的参与者在 8 周内接受了 4 次治疗。所有参与者在第 8 周时饮酒量均显著减少,但各条件之间的减少量相当。关于基线动机是否会显著调节条件对结果的影响的假设,通常没有得到支持。在讨论研究设计的优势和局限性时,讨论了未能为 MI 的假设性有效成分提供支持的原因。
