摘要
目的:考查华文认知能力量表的聚合效度和鉴别效度。方法:①被试来源:正常成人样本为无锡市精神卫生中心职工,正常儿童样本来自无锡市和芜湖中小学,弱智儿童样本来自培智学校,脑损害患者为无锡某医院神经科院患者,精神病患者样本来自无锡市精神卫生中心。所有受试者测试前都征得本人或监护人的知情同意。②工具:华文认知能力量表(简称CCAS)包含10个分测验:数字广度、汉词配对、数理运算、言语类推、快速组词、空间广度、图符配对、巧拼积木、图形类推、快速编码,测试是个别测验;韦氏智力量表,选用龚耀先修订的韦氏成人智力量表(WAIS-RC)和林传鼎修订的韦氏儿童智力量表(WISC-CR)。③评估标准:成绩以量表分表示,测验总成绩以离差商数(智商)表示,分数越高认知功能越好。④CCAS聚合效度检测:26名正常儿童检测CCAS和WISC-CR,26名正常成人同时检测CCAS和WAIS-RC,计算两者的相关性。⑤CCAS鉴别效度检测:用CCAS测试63名正常成人、32名脑损害患者、31名精神患者,正常儿童和弱智儿童各31名,比较组间差异。结果:所有被试均进入结果分析。①26名成人获得的CCAS言语智商、操作智商和总智商低于WAIS-RC相应得分(106.81,103.92和105.96分;112.12,113.15和113.77分),但两者间有显著性相关(r言语智商=0.775,r操作智商=0.621,r总智商=0.724)。②26名儿童获得的CCAS言语智商、操作智商和总智商低于WAIS-RC(107.50,103.62和106.00分;109.50,110.77和110.96分),两者显著性相关(r言语智商=0.888,r操作智商=0.779,r总智商=0.886)。③脑损害组和精神病组CCAS测得的总智商低于正常人(78.91±21.56,49.60±13.22,97.27±18.34,P<0.001),各项分测验得分也低于正常人(P<0.001),精神病组则低于脑损害组(P<0.001)。④弱智儿童CCAS测得的总智商低于正常儿童(44.06±13.17,101.81±14.35,P=0.000),各项分测验得分也低于正常儿童。结论:CCAS有比较好的聚合效度和鉴别效度。
AIM： To examine convergent validity and discriminate validity of Chinese Cognitive Ability Scale （CCAS）. METHODS： ①sources of subjects： The normal adults were recruited from the staffs in Wuxi Mental Health Center. The normal children were recruited from elementary schools or middle schools in both Wuxi City and Wuhu City. The mental retardation children were recruited from Special Education School in Wuhu City. The brain damage adults were from a hospital in Wuxi City. The chronic psychotic patients we.＇e inpatients in Wuxi Mental Health Center. All participants or the guardians were apprised what happened. ②scales： Chinese Cognitive Ability Scale （CCAS） has 10 subtests, such as Digit Span, Chinese Word Matching. Numeral Operation, Verbal Analogy, Word Stem Completion, Spatial Span, and Picture-Symbol Matching, Build Block, Pattern Analogy, Quick Coding. The test is individual test. The others are Wechsler adult intelligence scale-revised Chinese version （WAIS-RC） revised by Gong and Wechsler intelligence scale for children-Chinese revised （WISC-CR） revised by Lin. ③assessment criteria： The grade was the score of the scale. The total result was the intelligence quotient （IQ）, and the higher the score, the better the cognitive function was. ④ convergent validity of CCAS： The CCAS and WISC-CR were administered in 26 normal children, and CCAS and WAIS-RC were administered in 26 normal adults, and the correlation was calculated.⑤discriminate validity of CCAS： The CCAS was administered in 63 normal adults, 32 brain damage adults, 31 chronic psychotic patients, 31 normal children and 31 mental retardation children. The differences of them were compared. RESULTS： All participants were involved in the result analysis. ①The verbal intelligence quotient （VIQ）, performance intelligence quotient （PIQ） and full intelligence quotient （FIQ） of CCAS were lower than those of WAIS-RC in 26 adults （106.81,103.92 and 105.96 points; 112.12.113.15 and 113.77 points）. There were significant differences between them （rVIQ=0.775, rPIQ=0.621, rFIQ=0.724）. ②The VIQ, PIQ and FIQ of CCAS Were lower than those of WAIS-RC in 26 children （107.50,103.62 and 106.00 points;109.50,110.77 and 110.96 points）. There were significant correlation （rVIQ=0.888, rPIQ=0.779,rFIQ=0.886）. ③FIQ of CCAS in the brain damage group and chronic psychotic group was lower than that of normal persons （78.91 ±21.56,49.60±13.22,97.27±18.34, P 〈 0.001 ）. Score of each test was lower than that of normal persons （P 〈 0.001 ）, and lower in the chronic psychotic group than in the brain damage group （P 〈 0.001 ）. ④CCAS FIQ of mental retardation children was lower than that of normal children （44.06±13.17,101.81 ±14.35, P =0.000 ）. Score of each item was also lower than that of normal children. CONCLUSION： The CCAS has better convergent validity and discriminate validity.
