Comparability of WISC and Peabody IQs of Young Children from Three Heterogeneous Groups

Abstract

Peabody and WISC IQs of three groups of children from differing socioeconomic status levels and/or intellectual levels were compared. For the total sample of 67, correlations of .88, .88, .91 were obtained between the Peabody and WISC Verbal, Performance, and Full Scale IQs, respectively. The Peabody IQs correlated .74 with the WISC Full Scale for the middle-range of intelligence (kindergarten). Those of higher socioeconomic status in a child study center showed the highest correlation .57 between Peabody and WISC Performance Scale IQs. For more deprived children from Headstart IQs on the Peabody and WISC Verbal Scale correlated .63.
