摘要
目的：制定中华成人智力量表（Intelligence Scale for Chinese Adult，ISCA）老年常模并检验ISCA在老年人群中运用的信度、效度。方法：根据2000年全国第五次人口普查资料，对65岁以上老年人分年龄、性别、教育程度、兼顾职业和区域等变量按比率分层抽取了435人，建立量表的年龄常模。并结合重测、与脑梗死病理组对照等进行信度、效度检验。结果：制定了按年龄组的等值量表分、智商分数、指数分数和百分位常模：全量表智商的重测相关为0．96，各类智商平均分半信度是0．96—0．97。全量表的Cronbach’s α系数为0．89，各分测验的平均标准测量误在0．85～1．97之间，评分者信度0．95-0．98；ISCA总分与老年成套神经心理测验总分相关系数0．49，P〈0．01；脑梗死患者的测试成绩明显低于常模样本（P〈0．01）；验证性因素分析的结果显示，三因素模型拟合最佳。结论：建立了ISCA的65岁以上人群的常模，信度和效度检验符合心理测量学的要求。
Objective： To develop the national norms of Intelligence Scale for Chinese Adult （ISCA） for the elderly over 65 years old and examine its psychometric characteristics. Methods： The ISCA standardization was completed on 435 aged subjects. 2000 Census data was applied to the standardization sample in order to correctly represent individuals according to age, gender, educational level, geographic region, and occupation. Results： The sums of suhtest scaled scores for the ISCA IQ and Index scores were formed by summing each individual＇s actual age-corrected scaled scores on the relevant subtests. The ISCA had good reliability （test-retest coefficients of full scale IQ was 0.96, the average spilt-half reliability for the IQ scales ranged from 0.96 to 0.97,the Cronbaeh＇s α coefficient of full scale was 0.89, and the average standard error of measurement of subtest ranged from 0.85 to 1.97, the inter-rater reliabilities ranged from 0.95 to 0.98） The total score of ISCA related to that of Neuropsyehological Test Battery for Elderly （NTBE） was 0.49, which was statistically significant （P〈0.01）. Compared with those of the normal group, the IQ scores and Index scores of clients with cerebral infarction were lower significantly （P〈0.01）. By the way of confirmatory factor analysis （CFA）, three-factor model was fitted well. Conclusion： The national norms of ISCA for the elderly over 65 years old have been developed. The ISCA has generated good reliability and validity, and can be applied to assess cognitive functions of the elderly fully.
