Item difficulty of some Wechsler-Bellevue subtests

Abstract

Empirical evidence gained from clinical experience while administering the Wechsler-Bellevue scales suggested incorrect placement of items. Quantitative substantiation was sought in item analysis of 6 subtests using 300 records of normal individuals and various findings on 1,000 psychiatric patients. Several changes in order of presentation are indicated for nearly all the subtests investigated. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
