Investigated the validity of the Arithmetic + Vocabulary + Picture Arrangement + Block Design subtest combination as an estimate of the WAIS‐R Full Scale IQ in a smaple of 55 elderly patients. The correlation between the short‐form IQ and the WAIS‐R Full Scale IQ was highly significant, r (53) = 0.95, p < 0.001. A pairwise t ‐test computed between the mean IQs for the two forms was nonsignificant, t (54) < 1. Approximately one‐fourth of the S s showed changes in intelligence classification levels when the short form was used. The short form does not provide a precise estimate of IQ; however, it appears to have clinical utility as a screening device to identify patients with atypical cognitive functioning. The short form correctly categorized 84% of the current sample with respect to the presence or absence of abnormalities on the full WAIS‐R.
