Motivational interviewing (MI) is a client-centered, directive therapeutic style to enhance readiness for change by helping clients explore and resolve ambivalence. An evolution of Rogers's person-centered counseling approach, MI elicits the client's own motivations for change. The rapidly growing evidence base for MI is summarized in a new meta-analysis of 72 clinical trials spanning a range of target problems. The average short-term between-group effect size of MI was 0.77, decreasing to 0.30 at follow-ups to one year. Observed effect sizes of MI were larger with ethnic minority populations, and when the practice of MI was not manual-guided. The highly variable effectiveness of MI across providers, populations, target problems, and settings suggests a need to understand and specify how MI exerts its effects. Progress toward a theory of MI is described, as is research on how clinicians develop proficiency in this method.

动机面试。

动机访谈（MI）是一种以客户为中心的指导性治疗方式，旨在通过帮助客户探索和解决矛盾情绪来增强变革的准备能力。MI是罗杰斯（Rogers）以人为中心的咨询方法的演变，它激发了客户改变的动机。MI的迅速增长的证据基础在对涉及一系列目标问题的72项临床试验的新荟萃分析中进行了总结。心肌梗死的短期平均组间效应大小为0.77，随访至一年后降至0.30。在少数族裔人群中观察到的心梗的影响大小较大，并且在不采用人工指导的情况下，心梗的效果也较大。MI在提供者，人群，目标问题和环境之间的有效性差异很大，这表明需要了解并指定MI如何发挥其作用。
