The Learning Disability Index (LDI) was validated by an examination of the mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum, however, was found to measure Third Factor strengths/weaknesses as much as verbal-performance discrepancies.
学习障碍指数(LDI)通过对韦氏儿童智力量表修订版标准化样本中高LDI子集和低LDI子集的平均剖面图及人口统计学特征进行检验得以验证。然而,发现LDI连续体在测量第三因素优势/劣势方面与言语-操作差异同样有效。
