Notes on the reliability of Wechsler short forms.
Information is provided on the reliability of random short forms of Wechsler's intelligence scales and on the reliability of short forms that reduce the number of items within subtests rather than the number of subtests. The results demonstrate how much better than random the most reliable short forms of the scales are. They also show that reducing the number of items within subtests rather than the number of subtests exacts a steep price in reliability.
