冷漠无情特质量表(父母版)在中国学龄儿童中的效度和信度

Validity and reliability of inventory of callous-unemotional traits (parent version) in Chinese school-aged children

目的评价学龄儿童冷漠无情特质量表(inventory of callous-unemotional traits,ICU)(parent version,父母版)在中国学龄儿童中使用的效度和信度。方法研究对象选取符合精神障碍诊断与统计手册(第5版)(DSM-5)诊断标准的注意缺陷多动障碍(attention-deficit hyperactivity disorders,ADHD)儿童206例,以及普通小学正常儿童200例(年龄6~12岁)。由家长填写ICU(父母版)以评估儿童冷漠无情特质,并完成Conners父母用症状问卷(parent symptom questionnaire,PSQ)作为ICU(父母版)的同时效度,选取30名家长间隔2周再次填写ICU(父母版)。对数据进行验证性因素分析,并对同时效度、实证效度、内部一致性信度以及重测信度分析,以评估ICU的效度和信度。结果验证性因素分析显示,ICU二因子修订模型结构拟合良好[χ~2/df(116)=2.19,TLI=0.98,CFI=0.98,RMSEA=0.054];同时效度分析显示,ICU各因子与PSQ行为问题因子、冲动多动因子及多动指数呈中度相关(r=0.19~0.42,P<0.05)。实证效度显示,ADHD组的ICU得分均显著高于正常对照组得分(F=99.12~158.12,P<0.001)。ICU的内部一致性为0.76~0.83,重测信度为0.74~0.76。结论学龄儿童中文版ICU(父母版)具有良好的效度和信度。

Objective To evaluate the validity and reliability of inventory of callous-unemotional traits( ICU)parent version for school-aged children in China. Methods Parents of primary school students( n = 200),non-reference clinical patients who were diagnosed as having attention-deficit hyperactivity disorders( ADHD)( n = 206) by psychiatrist based on DSM-5 completed the ICU and Conners parent symptom questionnaire( PSQ). And 30 of them completed ICU retest after 2 weeks. Confirmatory factor analysis,concurrent validity,discriminative validity,internal consistency,and test-retest reliability were used to evaluate the validity and reliability of ICU. Results Confirmatory factor analysis showed that the devised two-factor model of ICU was reasonable: χ~2/df( 116) = 2. 19,TLI = 0. 98,CFI = 0. 98,RMSEA = 0. 054.Subscales of ICU were correlated( r = 0. 19-0. 42,P < 0. 05) with conduct problem,impulsive-hyperactivity and hyperactivity index of PSQ. ICU has good discriminate validity among ADHD and normal control groups( F = 92. 12-158. 12,P < 0. 001). Cronbach α coefficient was 0. 76-0. 83 and retest reliability was 0. 74-0. 76. Conclusion The reliability and validity of ICU are satisfactory in Chinese school-aged children.
