Validity and Clinical Utility of the Satz and Mogel Abbreviated form of the WAIS

IQ estimates based on WAIS protocols rescored by the abbreviated form are almost always within 6 IQ points of the full WAIS. The assumption was investigated that IQ estimates are as accurate when the abbreviated form is administered alone as they are when WAIS protocols are simply rescored. Thirty psychiatric patients responded first to the abbreviated WAIS and then responded to the items which were omitted. All IQ estimates from the abbreviated WAIS fell within 6 points of the non-abbreviated WAIS. The Satz and Mogel abbreviated WAIS is recommended as superior to other short forms in many clinical settings, not only because its IQ estimates are more accurate than most other short forms, but also because a wide range of qualitative material is provided by sampling from all 11 subscales.
