目的评价中文版SNAP-Ⅳ评定量表-父母版在学龄前儿童中的适用性。方法选择门诊诊断为注意缺陷多动障碍(ADHD)的儿童200名以及附近幼儿园的81名正常儿童为研究对象,年龄范围4岁~5岁11个月。请其家长填写SNAP-Ⅳ父母版后,问卷进行内部一致性和验证性因素分析,其中75名家长填写Conners问卷,265名家长填写CBCL量表以检查效标效度。32名家长间隔2周之后再次填写SNAP-Ⅳ以检查重测信度。结果 SNAP-Ⅳ重测信度为0.68~0.84(P<0.001),内部一致性系数为0.84~0.93;SNAP-Ⅳ与Conners问卷及CBCL量表因子相关系数为r=0.38~0.79(P<0.01);验证性因素分析显示,SNAP-Ⅳ3因子模型结构拟合良好;实证效度在SNAP-Ⅳ各因子评分上,ADHD组显著高于年龄、性别相匹配的正常组(t=-4.22~-9.67,P<0.001)。结论中文版SNAP-Ⅳ评定量表父母版在学前儿童中具有良好的信度和效度,适用于我国文化背景。
Objective To evaluate the applicability of Chinese version of SNAP-Ⅳ rating scale-parental version in preschool children. Methods 200 outpatients diagnosed as ADHD and 81 normal children from nearby kindergarten were selected as study subjects. Their ages ranged from 4 to 5 years and 11 months. After completing Parents ’SNAP-IV Parents’ Parents ’Parents’ Survey, 75 parents completed the Conners questionnaire and 265 parents completed the CBCL Scale to check the validity of the criteria. Thirty-two parents re-wrote SNAP-IV two weeks later to check the retest reliability. Results The retest reliability of SNAP-IV was 0.68-0.84 (P <0.001), and the internal consistency coefficient was 0.84-0.93. The correlation coefficient between SNAP-Ⅳ and Conners questionnaire and CBCL scale was r = 0.38-0.79 (P <0.01) ). The confirmatory factor analysis showed that the structure of SNAP-Ⅳ3 model fit well; the validity of the test was significantly higher in SNAP-Ⅳ factor scores than in normal subjects with age and gender (t = -4.22 ~ 9.67, P <0.001). Conclusion The Chinese version of SNAP-Ⅳ rating scale parental version has good reliability and validity in pre-school children and is suitable for our country’s cultural background.
