基于复杂度的抑郁障碍患者作答童年创伤问卷的面部运动特征分析

Analysis of facial movement features of patients with depressive disorders responding to Childhood Trauma Questionnaire based on Lempel-Ziv complexity

目的探究抑郁症患者在作答童年创伤问卷过程中的特异性面部运动特征。方法编制常识判断题目作为自然语料对照测验,招募47名抑郁障碍患者(患者组)及53名健康对照者(对照组)分别作答常识判断测验及童年创伤问卷,采用广义估计方程分析被试20个面部运动单元(AU)或组合的识别数据。结果患者组及对照组在童年创伤的五个维度上均存在显著差异。AU复杂度的模型检验报告患者组有6个AU的复杂度在童年创伤测验中与对照测验中存在显著差异,其中5个小于对照测验,1个大于对照测验;对照组有13个AU的复杂度在童年创伤测验中与对照测验中存在显著差异,全部小于对照测验。童年创伤测验中,8个AU的复杂度在患者组与对照组间存在显著差异;对照测验中,两组受试者不存在组间差异。结论抑郁症患者在回答童年创伤问卷过程中,比健康人群表现出更为显著的面部运动反应,为抑郁障碍多质融合检测中应用面部运动分析提供了理论基础。

Objective To explore the specific facial movement features of depressed patients in the process of answering the Childhood Trauma Questionnaire(CTQ).Methods Common sense judgment questionnaire was used as natural corpus control test.A total of 47 patients with depressive disorders(patient group)and 53 healthy controls(control group)were recruited to answer common sense judgment questionnaire and CTQ respectively.The identification data of 20 facial action units(AUs)or combinations were analyzed by generalized estimating equations.Results There were significant differences in five dimensions of CTQ between the patient group and the control group.The model test of the Lempel-Ziv complexity(LZC)of AU reported that there were significant differences in the LZC of 6 AUs between the CTQ and the control test in the patient group,of which 5 were less than the control test and 1 was greater than the control test.The LZC of 13 AUs in the control group was significantly different between the CTQ and the control test,and all of them were less than those in the control test.In CTQ,the LZC of 8 AUs was significantly different between the patient group and the control group.In the control test,there was no difference between the two groups.Conclusion In the process of answering the CTQ,the depressed patients show more significant facial movement responses than the healthy people,which provides a theoretical basis for the application of facial movement analysis in the detection of depressive disorders.
