Clinical utility of a WISC-R short form.

Examined the validity of the Vocabulary-Block Design subtest combination as an estimate of te WISC-R Full Scale IQ in a clinical population. One hundred and twenty children (67 males, 53 females) with school and/or behavioral problems between the ages of 6-6 and 16-6 were administered the standard WISC-R. Satisfactory correlations (.78-.88) were found between the short form IQ and the Full Scale IQ. Approximately one-third of the Ss showed changes in intelligence classification levels when the short form was used. The short form did not allow for precise IQ estimation. However, the short form showed promise as a screening device to identify children, with atypical cognitive functions and/or mental deficiency. The short form achieved a correct classification rate of 83%.
