TY - JOUR AU1 - Hanson, R. Karl AU2 - Hunsley, John AU3 - Parker, Kevin C. H. AB - Although the Weschler Adult Intelligence Scale (WAIS, Weschler, 1955) commonly is considered to have high validity as a measure of intelligence, the validity of the individual WAIS subtests has not won such wide‐spread acceptance. Ziskin (1981), for example, cautions against interpreting individual subtests because their validities are compromised by their low reliabilities in comparison to the WAIS Full Scale IQ. The present article empirically examines this theoretically predicted relationship between reliability and validity by comparing reliability estimates from the WAIS manual with meta‐analytically derived estimates of the validities of the WAIS subtests. The index of validity used in the present analysis was the proportion of variance that the scale could predict in relevant criterion measures. The WAIS Full Scale IQ was found to predictabout 42% of the variance in criterion measures; the subtests predicted, on average, about 20% of the variance. The validity values of the scales were found to be correlated highly with their reliabilities (r = 0.68, p < 0.005). These validity values were not correlated significantly with traditional factor analytically derived estimates of the extent to which the subtests assess global intelligence.
