Abstract: Objective To introduce the preschool pediatric symptom checklist(PPSC)into Chinese version,analysis its reliability and validity and establish its cutoff score. Methods A total of 506 samples aged 18~60 months were enrolled in Shanghai.A toatl of 65 samples were retested the reliability at interval of two to four weeks.Exploratory factor analysis was adopted. Results In Chinese version all the original 18 items were kept and four factors were extracted:externalizing,attention problems,parenting challenges and internalizing,which were accumulated as 49.66% of the total variance.Factor loadings of items were 0.35~0.81.The Cronbach's α coefficient was 0.83.The test-retest reliability was 0.53(P<0.01).ROC analysis yielded a sensitivity of 71.6% at a specificity of 70.6% when the cutting score was 12 for boys and a sensitivity of 67.3% at a specificity of 65.5% when the cutting score was 10 for girls. Conclusion sThe Chinese version of PPSC has good reliability and validity.It also has good sensitivity and specificity when the cutting score is 12 for boys and 10 for girls.It can be used to screen social emotional problems among children between 18 and 60 months.

摘要： 目的 引进幼儿儿科症状检查表(PPSC),分析中文版的信度和效度,并确定划界分。方法 选取上海市代表性市区18个月~5岁幼儿,回收有效量表506份。间隔2~4周的重测样本有65人。统计分析采用探索性因素分析等方法。结果 保留了量表中原有的18个项目,确定了4个因子:内化、注意问题、家长能力、外化,累计贡献率为49.66%。项目的因子载荷在0.35~0.81之间。量表的Cronbach's α系数为0.83,重测信度为0.53(P<0.01)。ROC分析显示,男童以12分为划界分,敏感性71.6%,特异性70.6%,女童以10分为划界分,敏感性67.3%,特异性65.5%。结论 PPSC中文版具有良好的信度和效度;男童以12分,女童以10分为划界分,该量表具有良好的敏感性和特异性,可用于筛查18个月~5岁幼儿社会性情绪问题。
