Development and preliminary validation of a Satz-Mogel short form of the WAIS-III in a sample of persons with substance abuse disorders.

We developed a Satz-Mogel short form of the WAIS-III and evaluated its accuracy for predicting IQs of 50 men with substance abuse disorders. Means for age, education, and Full Scale IQ were 44.20 years (SD = 7.23), 12.82years (SD = 1.53), and 98.06 (SD = 11.93). Correlations between the forms were significant for the 11 subtests (all rs> or =.79) and three IQs (all rs> or =.93). Short form estimated Verbal, Performance, and Full scale IQs were within +/-6 points of the WAIS-III 92% 80% and 90% of the time. The abbreviation may be used to estimate general intelligence, but interpretation of short-form-based IQ discrepancies should be avoided. The short form detected reliable WAIS-III Verbal-Performance IQ discrepancies only 67% of the time.
