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’sα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。
Objective To introduce the Infant Pediatric Symptom Checklist (PPSC) to analyze the reliability and validity of the Chinese version and to determine the boundaries. Methods The representative urban areas of Shanghai were selected from 18 months to 5 years old, and 506 effective scales were recovered. There are 65 retest samples at intervals of 2 to 4 weeks. Statistical analysis using exploratory factor analysis and other methods. The results retained the scale of the original 18 items, identified four factors: internalization, attention problems, parental ability, externalization, the cumulative contribution rate was 49.66%. The project’s factor loading is between 0.35 and 0.81. The Cronbach’s α coefficient of the scale was 0.83, and the test-retest reliability was 0.53 (P <0.01). According to the ROC analysis, boys were divided by 12 points, with a sensitivity of 71.6% and a specificity of 70.6%. Girls were divided by 10 points with a sensitivity of 67.3% and a specificity of 65.5%. Conclusion The Chinese version of PPSC has good reliability and validity. The score of 12 for boys and 10 for girls is good. The scale has good sensitivity and specificity and can be used for 18 months to 5 years of screening Social emotional problems in children.
