title: The comparative concurrent validities of the Shipley Institute of Living Scale and the Henmon-Nelson Tests of Mental Ability.
abstract: This study compared the abilities of the Shipley Institute of Living Scale and the Henmon-Nelson Tests of Mental Ability to predict Wechsler Adult Intelligence Scale-Revised (WAIS-R) scores in psychiatric hospital patients. The Henmon-Nelson DIQs accounted for about 50% more WAIS-R Verbal and Full Scale IQ variance than did the Shipley IQs, apparently because of their higher correlations with the Information, Vocabulary, and, perhaps, Similarities subtests. Because Henmon-Nelson scores were more variable and generally higher than their WAIS-R counterparts, statistical adjustments were needed to optimize Wechsler IQ estimates. Therefore, regression formulae and a conversion table for the estimation of WAIS-R Full Scale IQs from Henmon-Nelson and Shipley intelligence scores also are presented.
