Although motivational interviewing (MI) has been shown to be effective in changing health behaviors, its effects on smoking cessation have been mixed. The purpose of the present study is to assess factors of motivation and self-efficacy as they mediate the relationship between MI and smoking cessation. This is a secondary analysis of an MI based smoking cessation randomized trial. MI counseling was associated with change in smoking behaviors during a 12 months intervention but was not related to autonomous motivation, controlled motivation, or self-efficacy at baseline and 6 months, the hypothesized mediators. This study confirmed the pathway to quit smoking through increase in self-efficacy.
尽管动机性访谈（MI）已被证明在改变健康行为方面有效，但它对戒烟的效果却参差不齐。本研究旨在评估动机和自我效能感因素在 MI 与戒烟之间的中介作用。这是一项基于 MI 的戒烟随机试验的二次分析。MI 咨询与 12 个月干预期间的吸烟行为变化相关，但与自主动机、控制动机或自我效能感在基线和 6 个月时无关，这些都是假设的中介因素。本研究通过增加自我效能感证实了戒烟的途径。
