The cross-cultural validity of the Learning Disability Index: a reanalysis of Mishra's data.
This study investigated the nature of a learning disability index (LDI) for the objective assessment of verbal-nonverbal patterns of intellectual deficit on the WISC-R. The Factor II score coefficients derived from an unrotated principal components analysis of the WISC-R normative data, in combination with the individual's (or group's) average scaled scores, are used for this purpose. The mean LDI of various groups of learning disabled children, including Mishra's (1984a; 1984b) Mexican-American and Papago groups, are shown to be reliably different from the mean LDI of the normative population and thus demonstrate its cross-cultural validity.
