OBJECTIVE This study aimed to investigate the effects of changes in interpersonal cognitions on outcome during cognitive behavioral therapy (CBT) for generalized anxiety disorder (GAD) and how these effects are moderated by patients' interpersonal problems at intake. METHOD A sample of 80 adult patients diagnosed with GAD who were undergoing CBT within a randomized controlled trial completed a questionnaire concerning interpersonal problems at baseline as well as measures of changes in interpersonal and self-related cognitions and in worry severity session by session. We conducted dynamic structural equation modeling to estimate cross-lagged within-patient effects of changes in interpersonal cognitions on worry, adjusting for the effects of self-related cognitions. Furthermore, we included interpersonal problems as a moderator of the effects of changes in interpersonal cognitions. RESULTS We found significant cross-lagged effects of changes in both interpersonal cognitions and self-related cognitions on subsequent worry levels. Greater changes in interpersonal cognitions and self-related cognitions in a given session were associated with lower worry levels at the beginning of the next session. When adjusting for self-related cognitions, the effects of changes in interpersonal cognitions on subsequent worry remained significant. However, there were no interactive effects of changes in interpersonal cognitions by patients' interpersonal problems on worry severity. CONCLUSIONS The results present evidence supporting changes in interpersonal cognitions and self-related cognitions as relevant change mechanisms in CBT for GAD.

人际认知作为广泛性焦虑症认知行为治疗变化的机制？一种多级动态结构方程模型方法。

目的 本研究旨在调查人际认知的变化对广泛性焦虑症 (GAD) 认知行为治疗 (CBT) 期间结果的影响，以及这些影响如何通过患者摄入时的人际关系问题来调节。方法 在随机对照试验中接受 CBT 的 80 名诊断患有 GAD 的成年患者完成了一份关于基线人际问题的问卷，以及对人际和自我相关认知的变化以及逐个会话的担忧严重程度的测量。我们进行了动态结构方程建模，以估计人际认知变化对焦虑的交叉滞后影响，调整自我相关认知的影响。此外，我们将人际问题作为人际认知变化影响的调节因素。结果我们发现人际认知和自我相关认知的变化对随后的担忧水平有显着的交叉滞后影响。在特定会话中人际认知和自我相关认知的更大变化与下一次会话开始时较低的担忧水平相关。在调整自我相关认知时，人际认知变化对后续担忧的影响仍然显着。然而，患者的人际关系问题导致的人际认知变化对担忧严重程度没有交互作用。结论 结果提供的证据支持人际认知和自我相关认知的变化是 GAD 的 CBT 的相关变化机制。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
