强迫症患者快感缺失及其特征

The Characteristics of Anhedonia in Patients with Obsessive-compulsive Disorder

目的:本研究旨在探讨强迫症患者是否存在快感缺失症状及不同类型或成分快感缺失的表现特征。方法:使用Chapman躯体快感缺失量表中文版(RPAS-C)、Chapman社会快感缺失量表中文版(RSAS-C)、愉快情绪体验量表中文版(TEPS-CV)、贝克抑郁量表(BDI)、耶鲁-布朗强迫量表(Y-BOCS)对110名强迫症患者和90名正常被试施测,比较两组被试在躯体、社会、期待与消费快感水平上的差异。结果:与健康对照组比较,强迫症患者组在躯体快感、社会快感及消费性快感量表得分上显著降低(P<0.05),在期待性快感量表得分上差异不显著(P>0.05)。回归分析结果显示,强迫症患者的年龄、性别、受教育年限、抑郁水平、强迫思维、强迫行为和自知力水平对期待、消费、躯体和社会快感水平的影响均不显著(P>0.05)。结论:强迫症患者存在快感缺失,且主要表现为躯体快感、社会快感和消费性快感的缺失。

Objective:The current study aimed to explore whether patients with obsessive-compulsive disorder(OCD) have symptoms of anhedonia and the characteristics anhedonia.Methods:A total of 110 patients with OCD and 90 healthy controls(HCs)were assessed with RPAS-C,RSAS-C and CV-TEPS,Y-BOCS,and BDI.Analyses of covariance(ANCOVA)were used to compare the differences of anhedonia among OCD patients and the HCs.Regression analyses were used to analyze the effect of clinical variables in OCD patients on anhedonia.Results:Compared with HCs,OCD patients had lower scores on the physical anhedonia,social anhedonia and consummatory pleasure scale(P<0.005),but not the consummatory pleasure scale(P>0.05).No significant associations were observed for all the regression models(P>0.050).Conclusion:OCD patients exhibit the physical anhedonia,social anhedonia,consummatory anhedonia but not anticipatory anhedonia.
