The Leiter International Performance Scale, the Peabody Picture Vocabulary Test-Revised, and the Cognitive Triad of the Adaptive Behavior Scale were used to assess the intellectual functioning of 77 institutionalized mentally retarded adults. On the basis of their IQs, 30 were categorized as profoundly, 21 as severely, and 16 as moderately retarded (10 were unclassifiable because the Leiter and Peabody yielded disparate scores). Discriminant analysis in which category membership was predicted on the basis of the Cognitive Triad measures (Economic Activity, Language Development, and Number and Time Concepts) correctly classified 78% of the cases. There were no instances in which profoundly and moderately retarded individuals were mutually misclassified. Results support the use of the Cognitive Triad as an alternative for classifying lower functioning retarded persons.
使用莱特尔国际操作量表、修订版皮博迪图片词汇测验和适应性行为量表的认知三联来评估77名机构收容的成年智力迟钝者的智力功能。根据他们的智商，30人被归类为极重度智力迟钝，21人为重度智力迟钝，16人为中度智力迟钝（10人无法分类，因为莱特尔和皮博迪测验得出的分数不一致）。基于认知三联测量（经济活动、语言发展以及数字和时间概念）预测类别归属的判别分析正确分类了78%的案例。没有极重度和中度智力迟钝个体相互误分类的情况。结果支持将认知三联用作对低功能智力迟钝者进行分类的替代方法。
