The predictive power of movement and electrodermal activity (EDA) synchrony has been demonstrated in various studies. Although most studies have examined each synchrony modality separately, a growing interest in the simultaneous investigation of multiple modalities has emerged. Previous research has demonstrated the importance of disentangling within and between-dyad effects, however within and between-therapist effects have yet to be investigated. The aim of the present study was to test whether movement and EDA synchrony (measured both within and between therapists) predict across-session symptom change in two types of interventions (emotion-focused vs. cognitive). The results are based on 990 session segments of 90 clients with test anxiety who were treated with a six-session treatment program by 22 therapists, treating 3-15 clients each. Movement synchrony (on the basis of motion energy analysis (MEA) values) and EDA synchrony were quantified using cross-correlations. Symptom severity was assessed before each session using the state test anxiety measure. Movement and EDA synchrony correlated negatively (-0.19, p < .001). Moreover, higher movement synchrony as well as an interaction between movement and EDA synchrony was significantly associated with symptom improvement within, but not between therapists. In addition, an interaction between EDA synchrony and cognitive (versus emotion-focused) interventions was significantly associated with symptom improvement. These results provide initial evidence that therapists' average levels of synchrony may matter less than how synchronous they are with a specific client.
运动与皮肤电活动（EDA）同步性的预测能力已在多项研究中得到证实。尽管大多数研究分别考察了每种同步性模式，但对多种模式同时进行研究的兴趣日益浓厚。先前的研究已经证明了区分二元组内和二元组间效应的重要性，然而，治疗师内部和治疗师之间的效应尚未得到研究。本研究的目的是测试运动和EDA同步性（在治疗师内部和治疗师之间进行测量）是否能预测两种类型干预（情感聚焦型与认知型）中的跨疗程症状变化。结果基于90名患有考试焦虑症的客户的990个疗程片段，这些客户由22名治疗师进行为期六个疗程的治疗，每位治疗师治疗3 - 15名客户。使用互相关分析对运动同步性（基于运动能量分析（MEA）值）和EDA同步性进行量化。在每个疗程之前使用状态考试焦虑量表评估症状严重程度。运动和EDA同步性呈负相关（-0.19，p <.001）。此外，更高的运动同步性以及运动和EDA同步性之间的相互作用与治疗师内部而非治疗师之间的症状改善显著相关。此外，EDA同步性与认知（相对于情感聚焦型）干预之间的相互作用与症状改善显著相关。这些结果提供了初步证据，表明治疗师的平均同步水平可能不如他们与特定客户的同步程度重要。
