How Does Motivational Interviewing Reduce Alcohol Abuse?

描述（由申请人提供）： 尽管有明确的证据表明动机访谈的有效性，但人们对动机访谈背后的变化机制知之甚少。 本项目将评估一个有前途的理论模型的有效性动机访谈（MI）通过检查客户和治疗师在会话中的行为在项目匹配会议。 我们的因果模型是，MI是成功的，因为（在一定程度上）咨询师使用特定的治疗行为，引起客户的语言有利于改变。 如果这个模型得到支持，未来的动机访谈者将能够更好地关注这种方法中影响结果的成分，减少不相关的迷信治疗行为。 此外，阐明会话中的客户行为和饮酒结果之间的关系将具有为治疗师提供关于其临床干预措施有效性的持续即时反馈的优势，无论其理论取向如何。 这项研究提供了测试理论驱动的假设的优势，没有一个新的临床试验的费用为MI的因果机制。MATCH项目动机增强疗法（MET）的完整性和该项目中已收集的全面客户随访数据为MI作用机制的成本效益调查提供了工具。

DESCRIPTION (provided by applicant): Despite clear evidence of efficacy, little is known about the mechanisms of change underlying motivational interviewing. This project will evaluate a promising theoretical model for the effectiveness of motivational interviewing (MI) by examining client and therapist in-session behaviors during Project MATCH sessions. Our causal model is that Ml is successful because (and to the extent that) the counselor uses specific therapeutic behaviors that elicit client speech favoring change. If this model is supported, future motivational interviewers will be better able to focus on the components of this method that influence outcome, reducing irrelevant superstitious therapeutic behaviors. In addition, illuminating a relationship between in-session client behaviors and drinking outcomes would have the advantage of providing therapists with ongoing immediate feedback about the effectiveness of their clinical interventions, whatever their theoretical orientation. This study offers the advantage of testing theory-driven hypotheses about casual mechanisms for Ml without the expense of a new clinical trial. The integrity of the Project MATCH motivational enhancement therapy (MET) and the comprehensive client follow up data already collected in that project provide a vehicle for cost-effective investigation of mechanisms of action in MI.
