The Comprehensive Test of Adaptive Behavior (CTAB) yields indices of functioning in six categories (Self-Help Skills, Home Living Skills, Independent Living Skills, Social Skills, Sensory and Motor Skills, and Language Concepts and Academic-Skills) and a composite Total Score. A single factor, extracted through principal components analysis of standardization sample data, accounted for approximately 86% of the variance in the six category scores, portraying the CTAB as unidimensional rather than multidimensional. Therefore, rather than use of category scores, cautious interpretation of idiographic item clusters and the Total Score may be the most psychometrically sound procedure for evaluating CTAB results.
适应性行为综合测试（CTAB）产生六个类别的功能指标（自助技能、家庭生活技能、独立生活技能、社交技能、感官和运动技能以及语言概念和学术技能）和一个综合总分。通过对标准化样本数据进行主成分分析提取的单一因素，约占六个类别分数方差的86%，这表明CTAB是单维而非多维的。因此，对于评估CTAB结果而言，谨慎解读个性化项目集群和总分，而非使用类别分数，可能是最符合心理测量学要求的程序。
