进食障碍照料者技能量表中文版的效度和信度

Validity and reliability of the Chinese version of the Caregiver Skills Scale

目的:评估进食障碍照料者技能量表(CASK)中文版在神经性厌食和神经性贪食患者的照料者中应用的效度和信度。方法:选取符合DSM-5诊断标准的神经性厌食和神经性贪食患者的照料者151名,进行CASK测评;选取其中37名照料者进行照料者技能培训,比较培训前后CASK得分以检验实证效度。结果:探索性因子分析抽取大局观、自我照料、闭嘴、理解接纳、情商、挫折耐受6个因子;验证性因子分析显示6因子模型拟合良好(χ^(2)/df=2.47,CFI=0.84,TLI=0.82,RMSEA=0.09);照料者在参与照料技能培训后的CASK各维度得分及总分均高于培训前(均P<0.001)。总量表的Cronbachα系数为0.96,各维度的α系数为0.81~0.92;总量表的重测信度为0.85,各维度的重测信度为0.63~0.87。结论:进食障碍照料者技能量表中文版具有良好的效度和信度,可用于评估国内进食障碍患者照料者的照料技能水平。

Objective:To evaluate the validity and reliability of the Chinese version of the Caregiver Skills(CASK)scalein caregivers of anorexia and bulimia nervosa patients.Methods:A total of 151 caregivers of patients with anorexia nervosa and bulimia nervosa who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were selected for CASK evaluation.Among them,37 caregivers were selected for caregiver skills training,and their CASK scores before and after the training were compared to test the empirical validity.Result:Exploratory factor analysis extracted 6 factors,namely bigger picture,self-care,bitingyour-tongue,insight and acceptance,emotional intelligence and frustration tolerance.Confirmatory factor analysis showed that the 6-factor model was well fitted(χ^(2)/df=2.47,CFI=0.84,TLI=0.82,RMSEA=0.09).The scores of CASK dimensions and total scores of caregivers after attending the training were higher than those before the training(Ps<0.001).The Cronbach α coefficients were 0.96 for the total scale and 0.81-0.92 for each dimension.The retest reliabilities were 0.85 for the total scale and 0.63-0.87 for each dimension.Conclusion:The Chinese version of the caregiver coping skills scale has good validity and reliability,and could be used to evaluate the level of caregivers of eating disorders in China.
