除了少数例外，大多数关于抑郁症自动评估的研究只考虑了患者的行为，而排除了治疗师的行为。我们调查的人际协调（同步）的头部运动在病人治疗师的临床访谈。我们的样本包括被诊断为重度抑郁症的患者。在21周的时间内，以7周的间隔在临床访谈（汉密尔顿抑郁量表，HRSD）中记录他们。对于每个会话，从2D视频跟踪患者和治疗师的3D头部运动。水平（俯仰）和垂直（偏航）轴上的头部角度用于测量头部运动。使用窗口交叉相关测量患者和治疗师之间的头部运动的人际协调。使用峰值拾取算法研究头部运动的协调模式。使用分层线性模型（HLM）测量治疗过程中头部运动协调的变化。结果表明，病人治疗师头部运动同步性的强烈影响。研究发现，头部运动协调的二分体内变异性高于二分体间变异性，这意味着随着时间的推移，二分体中的差异高于二分体之间的差异。头部运动同步性在治疗过程中没有随着抑郁症严重程度的变化而改变。据我们所知，这项研究是第一次尝试分析病人和治疗师头部运动的相互影响与抑郁症的严重程度。
With few exceptions, most research in automated assessment of depression has considered only the patient's behavior to the exclusion of the therapist's behavior. We investigated the interpersonal coordination (synchrony) of head movement during patient-therapist clinical interviews. Our sample consisted of patients diagnosed with major depressive disorder. They were recorded in clinical interviews (Hamilton Rating Scale for Depression, HRSD) at 7-week intervals over a period of 21 weeks. For each session, patient and therapist 3D head movement was tracked from 2D videos. Head angles in the horizontal (pitch) and vertical (yaw) axes were used to measure head movement. Interpersonal coordination of head movement between patients and therapists was measured using windowed cross-correlation. Patterns of coordination in head movement were investigated using the peak picking algorithm. Changes in head movement coordination over the course of treatment were measured using a hierarchical linear model (HLM). The results indicated a strong effect for patient-therapist head movement synchrony. Within-dyad variability in head movement coordination was found to be higher than between-dyad variability, meaning that differences over time in a dyad were higher as compared to the differences between dyads. Head movement synchrony did not change over the course of treatment with change in depression severity. To the best of our knowledge, this study is the first attempt to analyze the mutual influence of patient-therapist head movement in relation to depression severity.
