中国-韦氏幼儿智力量表(C-WYCSI)的编制

CHINA-WECHSLER YOUNGER CHILDREN SCALE OF INTELLIGENCE (C-WYCSI)

本文介绍了中国-韦氏幼儿智力量表(C-WYCSI)的编制情况。C-WYCSI是以WPPSI为蓝本编制,包括城市常模(N=2200人)和农村常模(N=1120人)。作者从心理测量学角度对常模的构成、测验项目的筛选及上下限、信度和效度等问题进行了分析与讨论。结果提示:尽管C-WYCSI改变很大,但项目的难度和区分度是较满意的;城市常模的测验下限明显改善,但上限不及原量表;各种信度均达到测量学认可的水平;效度研究结果表明:C-WYCSI较好地保持了WPPSI的功能。

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI)was revised according to the cultural background of Chinese children.This new version is called the China-Wechsler Younger Children Scale ofIntelligence (C-WYCSI). Three subtests and the two-thirds items ofWPPSI were replaced. C-WYCSI consists of two sets of norms, one is madeup of urban children (N=2200) and another is made up of rural children(N=1120). The following psychometrical characteristics of the scale are considered: most floors of the subtests of this new scale were improvedbut some of the ceilings worsened. The average of reliability coefficientof the subtests are 0.79 (urban) and 0.83 (rural), the stability coeffic-ient of IQ are from 0.82 to 0.89 and the coefficient of correlation ofIQ on the C-WYCSI with IQ on the WPPSIa are from 0.786 to 0.878.
