: Motivational interviewing (MI) was originally developed to treat problematic drinking but is increasingly integrated into treatment for anxiety disorders. A causal model has been proposed which suggests technical and relational factors may account for the efficacy of MI. The technical hypothesis suggests that therapist MI-consistent behaviours are related to client change talk, and change talk is linked to treatment outcome. Research examining the technical hypothesis has typically been conducted in MI for substance use; therefore, the current study aimed to explore the technical hypothesis in MI for social anxiety disorder (SAD). : Participants diagnosed with SAD ( = 85) each received MI prior to receiving group cognitive-behavioural therapy (CBT). MI sessions were coded for behaviours relevant to the MI technical hypothesis. : The proportion of MI-consistent therapist behaviours and reflections of change language significantly predicted the proportion of change talk by the client during MI sessions; however, therapist and client behaviours did not predict treatment outcome. : The findings support one path of the MI causal model in the context of social anxiety, though indicate that the occurrence of these behaviours during an MI pre-treatment may not extend to predict treatment outcome following CBT.
动机性访谈（MI）最初是为治疗酗酒问题而开发的，但现在越来越多地被整合到焦虑障碍的治疗中。有人提出了一个因果模型，该模型表明技术和关系因素可能解释了 MI 的疗效。技术假设认为，治疗师与 MI 一致的行为与客户的改变谈话有关，而改变谈话与治疗结果有关。研究检验技术假设的研究通常是在物质使用的 MI 中进行的；因此，本研究旨在探索 MI 对社交焦虑障碍（SAD）的技术假设。参与者被诊断为 SAD（n=85），在接受团体认知行为治疗（CBT）之前都接受了 MI。MI 会话被编码为与 MI 技术假设相关的行为。MI 治疗师一致行为和改变语言的比例显著预测了客户在 MI 会话期间改变谈话的比例；然而，治疗师和客户的行为并不能预测治疗结果。研究结果支持社交焦虑症背景下 MI 因果模型的一条路径，尽管这表明这些行为在 MI 预处理期间的发生可能无法预测 CBT 后的治疗结果。
