This study was an effort to subtype adolescents' learning disabilities using scores on the Woodcock-Johnson Psycho-Educational Battery-Revised. A cluster analysis of 88 cases classified as learning disabled and 75 as nonlearning disabled was conducted to characterize subtypes. Two distinct subtypes emerged for the group while one for the nonlearning disabled group was identified. A multivariate analysis of variance to test for differences in scores among the identified subtypes yielded significant differences, suggesting that these students had two specific types of learning disorders. Cross-validation is essential.
本研究旨在利用伍德科克-约翰逊心理教育成套测验修订版的分数对青少年学习障碍进行亚型分类。对88例被归类为学习障碍的病例和75例非学习障碍的病例进行聚类分析，以描述亚型特征。该组出现了两种不同的亚型，而非学习障碍组只确定了一种。对所确定亚型之间的分数差异进行多变量方差分析，结果显示存在显著差异，这表明这些学生有两种特定类型的学习障碍。交叉验证至关重要。
