【摘要】：目的:简化改良婴幼儿孤独症量表(M-CHAT)中文修订版,并检验简化后其效度和信度。方法:删去M-CHAT中文修订版中既往研究显示效度或信度较差的5个条目(条目1、3、11、16和18),剩余的18个条目重新编号,各条目的内容和评分方法不变,形成M-CHAT中文简化版。以临床诊断作为金标准,与178例被试(93例孤独症儿童,85例正常儿童)的M-CHAT中文简化版筛查结果进行对比以检验效度。共有117例被试(56例孤独症儿童,61例正常儿童)的2位家长同时单独对被试进行M-CHAT中文简化版评定,以检测评分者信度;共有52例孤独症儿童的家长在2~4周后再次评定M-CHAT中文简化版,以检测重测信度。结果:当筛查界限分为13分时,M-CHAT中文简化版的灵敏度和特异度分别为92%和83%。阳性预测值为82.7%,阴性预测值为89.2%。M-CHAT中文简化版单项评分者信度kappa系数为0.41~0.75,均P0.01;总分评分者信度kappa系数为0.90(P0.01)。条目8的单项重测信度kappa系数为0.15,P0.05;其余条目单项重测信度kappa系数为0.47~0.80,P0.01;总分重测信度kappa系数为0.81,P0.01。内部一致性检验Cronbachα系数为0.94,P0.01。结论:M-CHAT中文简化版的效度和信度可能优于M-CHAT中文版及M-CHAT中文修订版,值得在早期孤独症筛查工作中推广。
[Abstract]:Objective: to simplify the revised Chinese version of the modified Autism scale for infants and Children (M-CHATA). And to test the validity and reliability of M-CHAT. Methods: to delete 5 items of M-CHAT Chinese revision that showed poor validity or reliability (item 1: 3111116 and 18g), renumber the remaining 18 entries, and keep the contents and scoring methods of each item unchanged. To form M-CHAT Chinese simplified version. Clinical diagnosis as the gold standard, The results of M-CHAT Chinese simplified Chinese screening were compared with 178 subjects (93 autistic children and 85 normal children) to test the validity. Two parents of 117 subjects with 56 autistic children and 61 normal children were compared with each other. The subjects were evaluated with M-CHAT Chinese simplified version. A total of 52 parents of autistic children were re-evaluated for M-CHAT simplified Chinese version after 2weeks. Results: the sensitivity and specificity of M-CHAT Chinese simplified version were 92% and 83.The positive predictive value was 82.7 and the negative predictive value was 89.2.M-CHAT single score reliability kappa coefficient. It was 0.41 卤0.75, all P 0.01. the kappa coefficient of total score score was 0.90 / P0.01.The kappa coefficient of item 8 was 0.15 / 0.05; the kappa coefficient of the rest item was 0.470.80 / P0.01; the kappa coefficient of total score's test-retest reliability was 0.81/ P0.01.The Cronbach 伪 coefficient of internal consistency test was 0.94 / P0.01respectively. The validity and reliability of the simplified version of M-CHAT may be better than that of the Chinese version of M-CHAT and the revised version of M-CHAT. It is worth popularizing in early autistic screening.
