title: Accuracy of the Satz-Mogel procedure in estimating WAIS-R IQs that are in the normal range.
abstract: WAIS-R protocols from 81 normal adults were rescored using the Satz-Mogel short form procedure. Although correlations were high between short form and actual WAIS-R scores for Verbal, Performance and Full Scale IQ (over .90), short form estimated FSIQs exceeded +/- 5 points from obtained scores in 55% of cases. At the subtest level, correlations were especially low between the short form and complete subtests for Similarities, Picture Arrangement, Picture Completion and Object Assembly. In those cases, estimated scaled scores exceeded the range of +/- 2 scaled score points from obtained subtest scores in over 25% of cases. Users of the Satz-Mogel procedure with normal range IQ groups are cautioned against employing it for other than a very gross screening device. Interpretations of individual subtests should be avoided.
