The Childhood Autism Rating Scale (CARS) was factor analyzed. Three factors emerged: Social Impairment (SI), Negative Emotionality (NE), and Distorted Sensory Response (DSR). Unit-weight factor scales showed moderate-to-good internal consistency. Cross-sectional analyses demonstrated that autistic (AUT) subjects were distinguished from subjects with pervasive developmental disorders (PDD) and nonpervasive developmental disorders (NPDD) by higher scores on SI. An SI cutoff score of 26 classified individuals as autistic vs. nonautistic with 78% accuracy. Longitudinal analyses showed that DSR was stable over 6 months of treatment, with little indication of symptom reduction. SI decreased over time across the diagnostic groups, but still showed significant continuity over the period. NE was most malleable and apparently sensitive to the effects of treatment.
对儿童自闭症评定量表（CARS）进行了因素分析。出现了三个因素：社交障碍（SI）、负面情绪（NE）和感觉反应扭曲（DSR）。单位加权因素量表显示出中等至良好的内部一致性。横断面分析表明，自闭症（AUT）受试者与广泛性发育障碍（PDD）和非广泛性发育障碍（NPDD）受试者的区别在于社交障碍得分较高。社交障碍的临界值为26分，以此将个体分为自闭症和非自闭症，准确率为78%。纵向分析表明，感觉反应扭曲在6个月的治疗期间保持稳定，几乎没有症状减轻的迹象。各诊断组的社交障碍随时间下降，但在此期间仍显示出显著的连续性。负面情绪最具可塑性，显然对治疗效果敏感。
