中国少年智力量表的信度研究

Reliability of the Chinese Intelligence Scale for Junior

目的:对中国少年智力量表(CISJ)进行信度分析。方法:采用分半相关、Alpha系数和复测相关等方法对CISJ常模样本资料作统计分析。结果:①分半信度:各分测验及言语、操作和总量表的分半相关系数在0.39～0.92之间,其中各常模年龄组样本,城镇为0.39～0.91、农村为0.42～0.92,而城镇总样本、农村总样本和全体样本则分别为0.57～0.88、0.63～0.90和0.61～0.89。②Alpha系数分析:除4个系数偏低(0.29～0.39)外,其余都比较高,在0.41～0.84之间,0.50以上的达到95%。③复测信度:各分测验及言语、操作、智力因素量表分数和智商的相关系数在0.47～0.85之间;除数字背诵分测验为0.47外,其余均在0.69以上。结论:CISJ具有较高的内部稳定性和复测一致性,是信度比较理想的智力量表。

Objective： To analysis reliability of the Chinese Intelligence Scale for Junior（CISJ）. Methods： Reliability of items in CISJ was analyzed by means of split-half correlation analyses, Cronbach＇s Alpha coefficient and test-retest correlation analyses. Results： Total sample split-half reliability was 0.61-0.89, and 0.57-0.88 in urban sample and 0.63- 0.90 in rural sample; Alpha coefficient was higher in inter correlation（0.29-0.84）; Test-retest correlation coefficient（r value） was 0.47-0.85. Conclusion： There is a prety high inter-items stability and a good test-retest consistency in CISJ, and it is an intelligence scale with good reliability.
