自悯量表中文版测评进食障碍患者的效度和信度

Validity and reliability of the Chinese version of Self-Compassion Scale in patients with eating disorders

目的:自悯量表是测量一般人群自悯水平的工具。本研究评价自悯量表中文版在进食障碍患者中的效度和信度。方法:由10名相关领域专业人员完成内容效度评价;选取136例符合精神障碍诊断与统计手册第5版(DSM-5)进食障碍诊断的患者进行量表测查,评价量表结构效度;以罗森伯格自尊量表(SES)、生活满意度量表(SWLS)、进食障碍检查自评问卷6.0(EDE-Q 6.0)为效标评价效标效度;选择20例患者2周内重测,评价重测信度。结果:各条目内容效度指数为0.70~1.00,S-CVI/Ave为0.96,内容效度良好。因子分析表明6因子模型拟合度好(χ2/df=1.70,RMSEA=0.07,CFI=0.92,TLI=0.91),因子负荷合理。自悯量表中文版与SES与SWLS的组内相关系数均为0.31,与EDE-Q 6.0得分负相关(r=-0.32)。总量表重测信度为0.80。结论:自悯量表中文版在进食障碍患者中具有中等效度和高等信度,可为我国进食障碍患者的心理评估提供临床测量工具。

Objective:The Self-Compassion Scale(SCS)is used to evaluate self-compassion in general popu-lation.The study was designed to evaluate the validity and reliability of the Chinese version of SCS in patients with eating disorders.Methods:Ten experts in the related disciplines completed the content validity evaluation.A total of 136 patients who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)eating dis-order diagnostic criteria were surveyed with SCS to evaluate structural validity.Using the Rosenberg Self-Esteem Scale(SES),Satisfaction with Life Scale(SWLS),and Eating Disorder Examination Questionnaire 6.0(EDE-Q 6.0)as gold criterion,the criterion validity of SCS was measured.Twenty patients were selected for retesting to e-valuate test-retest reliability.Results:The item-level content validity index(I-CVI)of each item was between 0.70 and 1.00,and the average scale-level content validity index(S-CVI/Ave)was 0.96,indicating good content validi-ty.Factor analysis indicated a good fit for the six-factor model with reasonable factor loadings:χ^(2)/df=1.70,RM-SEA=0.07,CFI=0.92,TLI=0.91.The Chinese version of the SCS had an ICC of 0.31 with both SES and SWLS,and a negative correlation with EDE-Q 6.0 scores(r=-0.32).The test-retest reliability of the scale was 0.80.Conclusion:The Chinese version of the SCS has moderate validity and high reliability in patients with eating disorders,and can provide a clinical measure tool for psychological assessment in the Chinese population with eating disorders.
