Given the importance of the alliance in psychotherapy, nonverbal synchrony has been suggested as a promising automatic objective marker of its levels and development. Accumulating research presents mixed results regarding the association between alliance and nonverbal synchrony. In the current study, we propose that one of the reasons for the inconsistencies is that previous studies did not disentangle trait-like characteristics from state-like changes occurring throughout treatment. To test this, we had 86 patients enrolled in an ongoing randomized controlled trial, along with their therapists, report their alliance levels after every session. Nonverbal movement synchrony was quantified by motion energy analysis for each of the 16 sessions of treatment. Findings suggest a significant association between nonverbal synchrony and the state-like effect of patient-reported alliance (p < .0001) but not for the trait-like effect. The results confirm the importance of disentangling the state-like and trait-like components because they may have distinct effects.

考虑到同盟在心理治疗中的重要性，有人提出非言语同步是其水平和发展的有希望的自动客观标记。越来越多的研究提出了关于联盟与非语言同步之间的关联的混合结果。在当前的研究中，我们认为出现不一致的原因之一是先前的研究并未将特征状特征与整个治疗过程中发生的状状变化区分开。为了测试这一点，我们让86名患者以及他们的治疗师参加了一项正在进行的随机对照试验，每次治疗后都要报告他们的联盟水平。通过运动能量分析对16个疗程中的每个疗程进行非言语运动同步性定量分析。p <.0001），但不适用于特质样效果。结果证实了区分状态和特质成分的重要性，因为它们可能具有不同的作用。
