OBJECTIVE The present study implements an automatic method of assessing arousal in vocal data as well as dynamic system models to explore intrapersonal and interpersonal affect dynamics within psychotherapy and to determine whether these dynamics are associated with treatment outcomes. METHOD The data of 21,133 mean vocal arousal observations were extracted from 279 therapy sessions in a sample of 30 clients treated by 24 therapists. Before and after each session, clients self-reported their well-being level, using the Outcome Rating Scale. RESULTS Both clients' and therapists' vocal arousal showed intrapersonal dampening. Specifically, although both therapists and clients departed from their baseline, their vocal arousal levels were "pulled" back to these baselines. In addition, both clients and therapists exhibited interpersonal dampening. Specifically, both the clients' and the therapists' levels of arousal were "pulled" toward the other party's arousal level, and clients were "pulled" by their therapists' vocal arousal toward their own baseline. These dynamics exhibited a linear change over the course of treatment: whereas interpersonal dampening decreased over time, there was an increase in intrapersonal dampening over time. In addition, higher levels of interpersonal dampening were associated with better session outcomes. CONCLUSIONS These findings demonstrate the advantages of using automatic vocal measures to capture nuanced intrapersonal and interpersonal affect dynamics in psychotherapy and demonstrate how these dynamics are associated with treatment gains.

人际和人际声音在心理治疗过程中会影响动态。

目的本研究实施了一种自动评估声音数据中唤醒力的方法以及动态系统模型，以探索心理疗法中人际和人际的影响动态，并确定这些动态是否与治疗结果相关。方法从24个治疗师治疗的30位客户的样本中，从279个治疗疗程中提取21,133个平均声音唤醒观察数据。在每次会议之前和之后，客户都使用“结果评分量表”自我报告他们的健康水平。结果服务对象和治疗师的声音唤醒都表现出人际抑制作用。具体而言，尽管治疗师和服务对象均偏离了基线，但他们的声音唤醒水平却被“拉”回了这些基线。此外，服务对象和治疗师都表现出人际交往的抑制作用。具体而言，客户和治疗师的唤醒水平都被“拉”到另一方的唤醒水平，客户被治疗师的声音唤醒被“拉”到自己的基线。这些动力学在治疗过程中表现出线性变化：人际阻尼随着时间的推移而降低，而人际阻尼随着时间的推移而增加。另外，较高的人际关系衰减与更好的会话效果相关。结论这些发现证明了在心理治疗中使用自动人声测量来捕捉细微的人际和人际影响动态的优势，并证明了这些动态如何与治疗效果相关联。
