目的:检验汉语版、哈萨克语版皮博迪图片词汇测评第四版(PPVT-4)的效度和信度。方法:2.5~7.5岁汉族儿童619例、哈萨克族儿童315例分别进行PPVT-4-A汉语版和哈萨克语版测量,汉族儿童364例和哈萨克族儿童304例分别进行PPVT-4-B汉语版和哈萨克语版测评(其中同时参加两种语言A、B版式测评的汉族儿童266例,哈萨克族儿童100例),采用韦克斯勒学前儿童智力测验(WPPSI)的言语智商(VIQ)和表达性词汇测验第二版A版式(EVT-2-A)检验效标效度,采用内部一致性信度、重测信度来检验信度。结果:汉语版、哈萨克语版PPVT-4-A得分及汉语版、哈萨克语版PPVT-4-B得分均与VIQ得分呈正相关(ICC=0.41~0.66,均P <0.01),与EVT-2-A得分也均呈正相关(ICC=0.68~0.86,均P <0.01)。汉语版及哈萨克语版PPVT-4-A、PPVT-4-B各年龄段的Cronbachα系数均在0.88以上,汉语版及哈萨克语版PPVT-4-A、PPVT-4-B版重测信度0.83~0.89 (均P <0.01)。结论:汉语版、哈萨克语版皮博迪图片词汇测验第四版具有良好效度和信度,可用于国内相应的儿童语言和认知发展研究。

Objective: To translate the form A and form B of the English version of the Peabody Picture Vocabulary Test-Forth Edition(PPVT-4) into Chinese and Kazakh versions and test their validity and reliability.Methods:Totally 619 Han nationality children and 315 Kazakh children aged 2.5 to 7.5 years were tested respectively with the translated Chinese and Kazakh versions of PPVT-4-A.Totally 364 Han children and 304 Kazakh children were tested separately with the Chinese and Kazakh versions of PPVT-4-B(Among them,266 Han children and 100 Kazakh children participated in the form A and B of both language tests).The Verbal Intelligence Quotient(VIQ) of Wechsler Preschool and Primary Scale of intelligence(WPPSI) and the Form A of the Expressive Vocabulary Test-Second Edition(EVT-2-A) were used as the criteria-related validity instrument.The internal consistency reliability,retest reliability were adopted to test the reliability of the versions of PPVT-4.Results: The Chinese and Kazakh versions of the form A and form B of the PPVT-4 were positively associated with the VIQ of WPPSI(ICC =0.66,0.47,0.60,0.41,Ps <0.01),and the versions of the PPVT-4 were positively associated with the form A of the EVT-2 too(ICC = 0.86,0.73,0.81,0.68,Ps <0.01).Cronbach’s α reliability coefficients were all above 0.88 in the Chinese and Kazakh versions of the form A and form B of the PPVT-4,the test-retest reliability(r) across 2 weeks for these versions were 0.83,0.86,0.89,0.87(Ps <0.01) separately.Conclusion: The translated Chinese and Kazakh versions of PPVT-4 for children has good validity and reliability,and could meet the needs of domestic research on children’s language and cognitive development.
