| Abstract: | Several short forms of the Wechsler Adult Intelligence Scale based upon several different rationales have been developed in recent years. The present study presents results of a cross-validation of 49 different short forms. Unlike previous studies, the short forms are cross-validated on both a psychiatric and on a nonpsychiatric population. Results revealed that for both the psychiatric and the nonpsychiatric populations (a) the mean estimated and the mean Full Scale scores were significantly different in only 3 of 98 comparisons; (6) correlations between estimated and obtained Full Scale scores were in the high .80's or .90's; (c) in the great majority of instances subjects were placed within one classification of their intelligence classification as revealed by scores on the total test.
