The validity of the two- and four-subset short forms of the Korean-Wechsler Adult Intelligence Scale was investigated using a sample of 72 psychiatric patients. Both short forms correlated highly with the Full Scale IQ(.92 and .97). However, pairwise t-tests computed between FSIQ and each short form indicated that a two-subtest short form yielded a significantly higher IQ, whereas a four-subtest short form did not significantly differ from the FSIQ. Finally, the rate of agreement with the Full Scale IQ, in terms of Wechsler's seven-category classification, was relatively low(58% and 72%) for each short form. It is concluded that the two- and four-subtest short forms should be used with caution in situations where a precise IQ measurement is required.
