《中国儿童发育量表》(4～6岁部分)信度与效度研究

目的对《中国儿童发育量表》(4~6岁部分)进行信度和效度分析。方法按照城区、性别和主要抚养人文化程度几个主要因素在北京地区抽取了916名儿童,其中男童490名,女童426名对量表进行信效度检验,信度包括重测信度和内部一致性系数,效度包括建构效度和校标关联效度。结果 1)重测信度:总发育商的重测信度为0.90,大运动、精细动作、适应能力、语言、社会行为分别为0.78、0.84、0.89、0.89、0.94;2)内部一致性系数:不同年龄段的总量表的Cranach'sα在0.86~0.91之间,大运动在0.71~0.87之间,精细动作在0.63~0.83之间,适应能力0.63~0.78之间,语言在0.48~0.78之间,社会行为在0.47~0.73之间;3)建构效度:每个项目的因子载荷系数均在0.3以上;4)校标关联效度:与《中国修订韦氏幼儿智力量表》的Pearson相关系数为0.78。结论《中国儿童发育量表》(4~6岁部分)延续传承了原量表0~4岁部分,信效度指标符合诊断量表的要求。

Psychometric analysis of the"China Developmental Scale for Children"(aged 4~6 years old)

Objective To test the reliability and validity of "China Developmental Scale for Children (CDSC)" aged from 4~6 years. Methods According the level of area,gender and the education of the major caregiver sampled 916 children(490 boys and 426 girls) were in Beijing to test the reliability and the validity of the CDSC including test-retest reliability,internal consistency coefficient,construct validity and criterion-related validity. Results 1)Test-retest reliability:the test-retest coefficients of developmental quotient (DQ) was 0.90,that of five dimensions (gross motor,fine motor,language,adaptive and social behavior) were 0.78,0.84,0.89,0.89,0.94 respectively; 2)Internal consistency coefficient:The Cranach's α of DQ ranged from 0.86 to 0.91,that of the five subsets ranged from 0.71 to 0.87,0.63 to 0.83,0.63 to 0.78,0.48 to 0.78 and 0.47 to 0.73 respectively.3)Construct validity:The factors loading of each item were all above 0.3.4)Criterion-related validity:The Pearson factor of Wechsler Preschool and Primary Scale of Intelligence Revised (WPPSI-R) was 0.78. Conclusion The CDSC (4~6 years old) has well succeed the CDSC (0~3 years old),it has good structure effectiveness and discrimination and matches the diagnose development scale parameters,it can be used as development diagnostic tool.
