中文版修订多维快感缺失量表在大学生中的信效度检验

目的 对中文版修订的多维快感缺失量表（DARS）的信效度作初步分析。方法 用中文版修订的多维快感缺失量表（DARS）测量330名大学生，并在4周后对其中83名进行重测。以贝克抑郁自评量表（BDI）、抑郁自评量表（SDS）、Snaith快感缺失量表（SHAPS）与时间体验愉悦量表（TEPS）为校标，计算校标关联效度。结果 通过因子分析验证支持量表的四因素结构模型. DARS整体的Cronbach’sα系数为0.909，重测信度为0.959;DARS 4个维度分量表爱好/业余活动（P/H）、食物/饮料（F/D）、感觉体验（SE）与社会活动（SA）的Cronbach’s α系数在0.79～0.86之间，分量表的重测信度在0.63～0.72之间。 DARS总分与BDI、SDS、SHAPS和TEPS总分及TEPS分量表分数之间均存在显著性相关,DARS 4个维度的分量表分数与BDI、SDS、SHAPS和TEPS总分及TEPS分量表分数之间，除了F/D与BDI、SE与BDI、SE与SHAPS之间的分数不存在显著相关，其他均存在显著性相关。结论 DARS具有良好的信效度，可以测量我国大学生抑郁症核心症状之一的快感缺失程度。

Reliability and validity of Chinese version of dimensional anhedonia rating scale used in undergraduates

Objective The aim of this study was to develop a cross-culture revision of Dimensional Anhedonia Rating Scale (DARS) and evaluate the reliability and validity of the Chinese version. Methods The Chinese version of DARS was used to assess 318 undergraduate students, and 83 participated in the retest four weeks later. BDI, SDS, SHAPS, TEPS and its subscales were used as the criteria-related validity instrument. Results Factor analyses showed the scale was composed of 4 factors which all supported the structure model. Cronbach’s ɑ coefficients of the Chinese version of DARS was 0.909, and test-retest reliability of the Chinese version of DARS was 0.959. Cronbach’s ɑ coefficients of the Chinese version of DARS’s subscales Pastimes/Hobbies (PH), Foods/Drinks (FD), Sensory experiences (SE) and Social activities (SA) were between 0.79 and 0.86, and their test-retest reliability were between 0.63 and 0.72. The total score of DARS and four subscales were positively associated with that of BDI, SDS, SHAPS, TEPS and its subscales in the total sample, and FD and BDI, SE and BDI, SHAPS did not have significant correlation. Conclusion The Chinese version of DARS has acceptable psychometric quality. It can be used to measure the anhedonia of Chinese college students.
