The importance of interdependence processes of patients' and therapists' affect experiences (AEs) over the course of treatment has been highlighted by numerous therapeutic orientations. Yet, most studies have focused on snapshot observations and there is a dearth of knowledge regarding session-to-session patient-therapist AE interdependence, through which the dynamics of AE across treatment can be explored. Using actor-partner interdependence model analysis in a sample of 70 patient-therapist dyads across 16 sessions of psychodynamic treatment, the present study investigated whether (a) at the sample level, patients' and therapists' changes in positive and negative AEs are interdependent throughout treatment, and (b) whether individuals' differences in AE interdependence can be explained by patients' anticipated or general ability to form a strong therapeutic alliance, and by the actual alliance with the therapist during treatment. Findings suggest that patients' and therapists' changes in positive and negative AEs are interdependent throughout treatment. Moderation analysis suggests that when patients report stronger anticipated ability to form a strong alliance, an increase in therapists' negative AE from one session to another predicts a greater decrease in their patients' negative AE in the following session. Additionally, focusing on patients' actual alliance with the therapist during treatment, when patients report a stronger alliance with their therapist, a subsequent increase in therapists' positive and negative AEs from one session to another predicts greater subsequent increases in their patients' positive and negative AEs in the next session. Taken together, findings suggest that patients' and therapists' AEs are interdependent throughout treatment, though individual differences exist.

了解患者和治疗师影响体验的相互依赖性：样本和个体差异水平的检查。

许多治疗方向都强调了患者和治疗师在治疗过程中的情感体验（AE）相互依赖过程的重要性。然而，大多数研究都集中在快照观察上，并且缺乏关于每次治疗中患者与治疗师 AE 相互依赖性的知识，通过这种依赖性可以探索治疗过程中 AE 的动态。本研究通过对 16 次心理动力学治疗中的 70 名患者-治疗师二人组样本进行演员-伴侣相互依赖模型分析，调查 (a) 在样本水平上，患者和治疗师在积极和消极 AE 方面的变化是否在整个过程中是相互依赖的(b) AE 相互依赖性的个体差异是否可以通过患者形成强大治疗联盟的预期或一般能力以及治疗期间与治疗师的实际联盟来解释。研究结果表明，在整个治疗过程中，患者和治疗师的阳性和阴性不良事件的变化是相互依赖的。调节分析表明，当患者报告形成强大联盟的预期能力更强时，治疗师从一个疗程到另一个疗程的阴性 AE 增加，预示着患者在下一个疗程中的阴性 AE 会大幅减少。此外，关注患者在治疗期间与治疗师的实际联盟，当患者报告与治疗师的联盟更牢固时，治疗师的阳性和阴性 AE 从一个疗程到另一疗程的后续增加预示着患者的阳性和阴性 AE 的后续增加更大下一次会议中的 AE。总而言之，研究结果表明，尽管存在个体差异，但患者和治疗师的不良事件在整个治疗过程中是相互依赖的。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
