OBJECTIVE Client-therapist physiological synchrony has recently attracted significant empirical attention. Recent theoretical accounts propose that physiological linkages should not be considered a stable dyadic virtue but rather a dynamic process that depends on the situational context in which they transpire. The present study adopted a "momentary" (vs. "global") approach that focuses on therapist-client physiological synchrony over relatively short periods of time. These temporal data served to examine the interplay between patterns of synchrony (in-phase vs. antiphase) and clients' momentary emotional experiences (inhibited/unproductive, productive, and positive). Synchrony was assessed by measuring respiratory sinus arrhythmia (RSA), an autonomic index that is known to be associated with interpersonal emotion regulation. METHOD Data were drawn from 28 clients undergoing a 16-session supportive-expressive dynamic therapy for depression. Clients' and therapists' electrocardiography were recorded in five sessions; clients' emotional experiences were coded at the speech-turn level. After each session, the clients also completed the session evaluation scale. RESULTS Client-therapist dyads had greater momentary RSA synchrony than would be predicted by chance. Compared to moments of unproductive emotional experience, greater antiphase synchrony was observed during moments of productive emotional experiences. In addition, compared to moments of unproductive emotional experience, greater in-phase and antiphase synchrony were observed during moments of positive emotional experiences. These patterns of synchrony were associated with clients' favorable evaluations of the session. CONCLUSION By considering the dynamic nature of synchrony, these findings provide a fine-grained picture of physiological synchrony and its potential effects on therapy.

客户的情感体验作为客户-治疗师生理同步的动态背景。

目的 来访者-治疗师的生理同步性最近引起了显着的实证关注。最近的理论解释表明，不应将生理联系视为一种稳定的二元美德，而应将其视为一个动态过程，该过程取决于它们发生的情境。本研究采用了一种“瞬时”（相对于“全局”）方法，该方法侧重于相对较短时间内的治疗师-客户生理同步。这些时间数据用于检查同步模式（同相与反相）与客户的瞬间情绪体验（抑制/无效、有效和积极）之间的相互作用。通过测量呼吸性窦性心律失常 (RSA) 来评估同步性，已知与人际情绪调节相关的自主神经指数。方法 数据来自 28 位接受 16 次抑郁症支持性表达动态疗法的患者。客户和治疗师的心电图记录在五个疗程中；来访者的情感体验被编码在言语转向水平。每次会议结束后，客户还完成了会议评估量表。结果 客户-治疗师二人组的瞬时 RSA 同步性比偶然预测的要大。与非生产性情感体验的时刻相比，在生产性情感体验的时刻观察到更大的反相同步。此外，相较于无益的情感体验时刻，在积极情绪体验的时刻观察到更大的同相和反相同步。这些同步模式与客户对会议的好评有关。结论 通过考虑同步的动态特性，这些发现提供了生理同步及其对治疗的潜在影响的精细图景。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
