摘　　要：目的:考查华文认知能力量表(CCAS)的信度和效度。方法:用CCAS对321名正常儿童、275名正常成人、32名脑损害病人和31名弱智儿童进行个别测试,其中26名成人和26名儿童同时接受了韦氏智力量表(WAIS-RC和WISC-CR)测试,计算稳定系数、分半相关、α系数、概化系数、效标效度和鉴别效度等指标。结果:儿童各分测验和量表粗分的重测信度分别为0.732-0.894和0.919-0.960,成人和老年人分测验和量表粗分的重测信度分别为0.859-0.937和0.968-0.981;儿童样本分测验和量表粗分的信度系数分别为0.810-0.976(分半)、0.737-0.965(α系数)和0.737-0.965(概化),成人和老年样本分测验和量表粗分的信度系数分别为0.829-0.979、0.747-0.967和0.747-0.967;CCAS的言语、操作和总智商与WAIS-RC(VIQ0.775,PIQ0.621,FIQ0.724)和WISC-CR(VIQ0.888,PIQ0.779,FIQ0.886)的相应智商有显著性相关,CCAS的平均智商低于WAIS-RC(5.3,9.2,7.8)和WISC-CR(2.0,7.2,5.0)的平均智商。与正常对照组相比,脑损害组(VIQ80.50,PIQ80.59,FIQ78.91)、和弱智组(VIQ43.68,PIQ49.77,FIQ44.06)的智力明显受损。结论:华文认知能力量表具有很好重测稳定性、内部一致性、效标效度和鉴别效度。Objective： To examine reliability and validity of Chinese Cognitive Ability Scale （CCAS） . Methods： The CCAS was administered 321 children, 275 adults, 32 patients with brain damage, and 31 children with mental retardation. Out of them, 26 children were tested with WISC-CR and 26 adults with WAIS-RC. Results： The test-retest reliahility coefficients of subtests and scales ranged from 0. 732 to 0. 894, 0. 919 to 0. 960 for children, 0. 859 to 0. 937, 0. 968 to 0. 981 for adults ; The reliability coefficients for children （ quick coding was omitted） ranged from 0. 810 -0. 928 （Split-half） , 0. 737 -0. 923 （Cronbach＇s α） and 0. 737 -0. 945 （generalizability） for subtests, 0. 939 - 0. 976, 0. 898 - 0. 965 and 0. 898 - 0. 965 for scales ; Coefficients for adults ranged from 0. 829 - 0. 948, 0. 747 -0. 941 and 0. 747 - 0. 941 for subtests, 0. 945 - 0. 979, 0. 915 - 0. 967 and 0. 915 - 0. 967 for scales; The CCAS IQs were high correlated with WAIS-RC IQs （ VIQ = o. 775, PIQ = 0. 621, FIQ = 0. 724） and WISC-CR IQs （ VIQ =0. 888, PIQ =0. 779, FIQ =0. 886） , the CCAS VIQ, PIQ, and FIQ were 5.3, 9. 2, and 7. 8 points less than WAIS-RC, and 2. 0, 7. 2, and 5.0 points less than WISC-CR; Comparing with normal groups, mean IQs of brain damaged adults （ VIQ = 80. 50, PIQ = 80. 59, FIQ = 78.91 ） and mental retardation children （ VIQ = 43.68, PIQ =49. 77, FIQ =44. 06） were much lower. Conclusion： The Chinese Cognitive Ability Scale has excellent retest stability, internal consistency reliability, convergent and discriminant validity.
