Abbreviated Forms of the WISC-R
Keyword(s):
The purpose of the present study was to validate the effectiveness of three forms of abbreviated WISC-Rs. 100 protocols from a group of mentally retarded and language/learning impaired children were rescored according to three different methods of abbreviation previously used with the WISC. Part-whole correlations, correlations of IQs from the original and short-forms, were quite high for each of the short-form methods, ranging from .92 to .93 for the Full Scale IQ. Though tests for significance between correlations demonstrated no statistically significant differences, the accuracy of the Finch, et al. method (1973) was superior in estimating IQ. All three methods are derived from complete administration of the WISC-R.
