A comparison of an ITPA estimated psycholinguistic quotient and WISC-R IQs for developmentally disabled children

Abstract

Compared an estimated Psycholinguistic Quotient, based on Cronkhite and Penner's (1975) revised scoring procedure for the ITPA Psycholinguistic Age, to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children. The Quotient entered into strong relationships with the WISC-R Verbal and Full Scale IQs. The diagnostic significance of these correlations was discussed. The data indicated that the estimated Psycholinguistic Quotient was a valid measure for screening intellectual status in this population.
