中华成人智力量表的初步编制

The Intelligence Scale for Chinese Adults:Item Analysis,Reliability and Validity

目的:编制一套适合我国16岁以上人群的成人智力量表。方法:以Cattell-Horn-Carroll理论作为编制量表的基本理论框架,量表由3个分量表12个分测验组成。根据湖南省第五次人口普查资料,在长沙地区分层按比例随机选取16～82岁正常成年人400例,进行条目分析及信效度检验。结果:各分测验难度在0.45～0.74之间,平均难度0.53;各分测验及全量表的重测相关系数为0.72～0.97;探索性因素分析抽取的三个因子解释了总方差的75%;验证性因素分析拟合三因素模型最佳。结论:中华成人智力量表的条目质量及信效度符合心理测量学的基本要求。

Objective： To develop an Intelligence Scale for Adults aged over 16 years old. Methods： The ISCA had been constructed based on Cattell-Horn-Carroll theory, including three subscales and 12 subtests. The standardization sample（N=400） was stratified according to the census of Hunan province（2000） on the variables age （from 16 to 82）, sex, education and occupation from Changsha urban people. Item analysis, reliability and validity research were tested. Resuits： Totally, the subtest average index of difficulty was 0.53, and the test-retest coefficients of subtests ranged from 0.72 to 0.97. By way of EFA, one, two, three and four factors were extracted respectively, but CFA showed that only three factors model was fitted well, which were named as fluid intelligence factor, crystallized intelligence factor and freedom from distractibility factor, which explained 75% variance. Conclusion： The structure,reliability and validity of ISCA are acceptable.
