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.
本文提供了关于韦氏智力量表随机简短形式的信度信息,以及关于通过减少分测验中的项目数量而非分测验数量所得到的简短形式的信度信息。结果表明,量表中最可靠的简短形式比随机简短形式要好得多。它们还表明,减少分测验中的项目数量而非分测验数量,会在信度上付出高昂代价。
