Motivational interviewing (MI) has been identified as an effective treatment for health behaviors. Understanding the mechanisms of MI could have practical implications for MI delivery. This review is the first to examine mechanisms within MI that affect health behavior outcomes and summarizes and evaluates the evidence.
A systematic literature search was conducted in PSYCHINFO, MEDLINE and EMBASE to identify studies that delivered individual MI in the context of health behaviors, excluding addictions, and investigated mechanisms of MI. Effect sizes were calculated.
291 studies were identified and 37 met the inclusion criteria. Few of the 37 studies included, conducted mediation analyses. MI spirit and motivation were the most promising mechanisms of MI. Although self-efficacy was the most researched, it was not identified as a mechanism of MI. Study quality was generally poor.
Although this review has indicated possible mechanisms by which MI could influence health behavior outcomes, it also highlights that more high quality research is needed, looking at other possible mechanisms or causal pathways within health behavior outcomes.
MI spirit possibly plays an important role within MI and may potentially be used to evoke change talk which links to outcomes.
动机性访谈（MI）已被确认为一种针对健康行为的有效治疗方法。了解MI的作用机制可能对MI的实施具有实际意义。本综述首次探讨了MI中影响健康行为结果的机制，并对相关证据进行了总结和评估。
在PSYCHINFO、MEDLINE和EMBASE数据库中进行了系统的文献检索，以识别在健康行为背景下实施个体MI（不包括成瘾行为）并研究MI作用机制的研究。计算效应量。
共识别出291项研究，其中37项符合纳入标准。纳入的37项研究中很少进行中介分析。MI精神和动机是MI最有前景的作用机制。虽然自我效能感是研究最多的，但它未被确定为MI的作用机制。研究质量普遍较差。
尽管本综述指出了MI可能影响健康行为结果的潜在机制，但也强调需要更多高质量的研究，关注健康行为结果中的其他可能机制或因果途径。
MI精神可能在MI中发挥重要作用，并可能用于引发与结果相关的改变谈话。
