Abstract

While the WISC-R is the most widely adopted measurement of intelligence in various eductaional and clinical settings, administering and scoring the ten-subtest battery could be time-consuming, and thus uneconomical, for certain purposes of patient placement or classification. Hence to construct an abbreviated form of WISC-R with satisfactory reliability and validity would be productive for improving efficiency and cutting expenses.The present study analyzed 98 WISC-R protocols with an stepwise multiple regression analysis to identify, from the whole battery, an minimal pool of subtests for making up an abbreviated test such that scores of which would predict the full scale IQ score of the complete test. Given two priori conditions that a) the standard error of estimate (SEE) of the abbreviated form should be smaller than that of the norm in full scale test, and b) the correlation coefficient between the abbreviated form score and the full scale score should be over 0.95, a selected battery of five subtests--Picture Arrangement, Arithmetic, Comprehension. Object Assembly and Coding (arranged in an descending order of correlation coefficient) were found to render a test score with acceptable accuracy in predicting the full scale IQ score of the complete WISC-R. This abbreviated WISC-R could save time and effort by one-half in terms of administration and scoring without compromising the desired functioning of the WISC-R test and thus would be more practical for clinical use in certain circumstances.
