Psychotherapists, who use their communicative skills to assist people, review their dialogue practices and improve their skills from their experiences. However, technology has not been fully exploited for this purpose. In this study, we analyze the use of head movements during actual psychotherapeutic dialogues between two participants-therapist and client-using video recordings and head-mounted accelerometers. Accelerometers have been utilized in the mental health domain but not for analyzing mental health related communications. We examined the relationship between the state of the interaction and temporally varying head nod and movement patterns in psychological counseling sessions. Head nods were manually annotated and the head movements were measured using accelerometers. Head nod counts were analyzed based on annotations taken from video data. We conducted cross-correlation analysis of the head movements of the two participants using the accelerometer data. The results of two case studies suggest that upward and downward head nod count patterns may reflect stage transitions in counseling dialogues and that peaks of head movement synchrony may be related to emphasis in the interaction.
心理治疗师利用他们的沟通技巧来帮助他人，他们会回顾自己的对话实践，并从经验中提高自己的技能。然而，这项技术尚未得到充分利用。在这项研究中，我们使用视频记录和头戴式加速度计分析了两名参与者（治疗师和客户）之间实际心理治疗对话中头部运动的使用情况。加速度计已在心理健康领域得到应用，但尚未用于分析与心理健康相关的沟通。我们研究了互动状态与心理咨询过程中头部点头和运动模式的时变之间的关系。手动注释了头部点头，并用加速度计测量了头部运动。根据视频数据中的注释分析了头部点头的计数。我们使用加速度计数据对两个参与者的头部运动进行了互相关分析。两项案例研究的结果表明，向上和向下的头部点头计数模式可能反映了咨询对话中的阶段转变，而头部运动同步的峰值可能与互动中的重点有关。
