The relative efficacy of two short forms of the WAIS‐R with respect to accurate subtest profile scatter was examined (N = 50). The subtest scores of both the split‐half Satz‐Mogel (S‐M) short form and the criterion referenced Modified WAIS‐R (WAIS‐RM) short form were found to differ significantly from full length WAIS‐R subtest scores. Direct comparison of the S‐M to the WAIS‐RM showed the WAIS‐RM to provide a closer approximation of full length WAIS‐R subtest variability. Therefore, selection of the appropriate WAIS‐R short form is best guided by the extent to which accuracy of inter‐subtest variability is needed.
