This study analyzed patient-therapist in-session interpersonal complementarity effects on the therapeutic alliance and depression severity during the initial and working phase of cognitive-behavioral therapy for depression. It also explored whether patients' interpersonal problems moderate those complementarity effects. We drew on a sample of 90 dyads derived from a randomized controlled trial of two cognitive-behavioral therapies for depression. Using an observer-based measure, we assessed patients' and therapists' interpersonal behavior in Sessions 1, 5, 9, and 13 and computed their complementarity regarding interpersonal affiliation (i.e., correspondence) and dominance (i.e., reciprocity). Patients completed measures of interpersonal problems at baseline and session-by-session measures of depression severity and quality of the therapeutic alliance. Response surface analyses based on polynomial regressions showed that patient-therapist complementarity in higher affiliative behaviors was associated with a stronger alliance. Interpersonal problems regarding agency moderated the complementarity effects of the dominance dimensions on depression severity. Overly dominant patients benefited more from a nonreciprocal relationship in the dominance dimension, whereas submissive patients benefited more from complementarity in that dimension. Furthermore, interpersonal problems of communion significantly moderated the effects of complementarity in affiliative behaviors on both the alliance and outcome. These results suggest the relevance of both interpersonal correspondence and reciprocity for the psychotherapy process, informing clinical practice in terms of interpersonal responsiveness. The moderation effects of interpersonal problems provide preliminary evidence, which should be replicated in future research, to determine relevant markers indicating for whom a complementary approach would be beneficial in cognitive therapy for depression.

患者与治疗师之间的人际互补性对抑郁症认知行为疗法联盟和结果的影响：走向人际反应。

本研究分析了在抑郁症认知行为治疗的初始和工作阶段，患者与治疗师在治疗过程中的人际互补性对治疗联盟和抑郁症严重程度的影响。它还探讨了患者的人际关系问题是否会减弱这些互补效应。我们从一项针对两种抑郁症认知行为疗法的随机对照试验中抽取了 90 个双人组样本。使用基于观察者的测量方法，我们评估了患者和治疗师在第 1、5、9 和 13 节中的人际行为，并计算了他们在人际关系（即对应）和主导地位（即互惠）方面的互补性。患者完成了基线人际关系问题的测量以及抑郁症严重程度和治疗联盟质量的逐次测量。基于多项式回归的响应面分析表明，患者与治疗师在较高亲和行为中的互补性与更强的联盟相关。有关代理的人际问题调节了主导维度对抑郁严重程度的互补效应。过度支配的患者从支配维度的非互惠关系中受益更多，而顺从的患者从该维度的互补性中受益更多。此外，人际交流问题显着减弱了亲和行为的互补性对联盟和结果的影响。这些结果表明人际对应和互惠与心理治疗过程的相关性，为人际反应方面的临床实践提供信息。人际问题的调节作用提供了初步证据，应在未来的研究中重复使用，以确定相关标记，表明补充方法对抑郁症的认知治疗有益于哪些人。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。确定相关标记，表明补充方法对抑郁症认知治疗有益于哪些人。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。确定相关标记，表明补充方法对抑郁症的认知治疗有益。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
