Validity of short forms of the Wechsler-Bellevue scale for mental defectives.

Abstract
An analysis is made of the validty of suggested abbreviated forms of the W-B test for a representative group of 154 institutionalized mental defectives. Several abbreviated scales were found to lack validity for this group. The Geil scale containing comprehension, similarities, digit span, and picture arrangement is the most applicable for full scale prediction. There is danger in standardizing a scale on one sample of the population and then attempting to use it on a different clinical group. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
