【目的】修订广泛性发育障碍筛查问卷(Pervasive Developmental Disorders Screening Questionnaire,PDDSQ),并进行信度、效度及敏感度、特异度分析,为我国大样本人群开展孤独症早期筛查提供简便、有效的工具。【方法】选择孤独症、脑瘫和精神发育迟滞、正常对照儿童12～47月共639名、4～18岁727名作为研究对象,检验PDDSQ中文版的信度和效度。【结果】采用探索性因素分析,两个年龄段问卷各提取2个因子,用AMOS 17.0进行结构方程模型的验证性因素分析,结果显示具有较好的效度。2个年龄段的筛查问卷内部一致性信度Cronbachα系数分别为0.903和0.925,分半信度分别为0.818和0.861,一个月后重测信度分别为0.707和0.641。【结论】修订后的PDDSQ中文版具有较好的信度和效度,适用于中国开展孤独症人群筛查。
【Objective】 Retrospective screening of Pervasive Developmental Disorders Screening Questionnaires (PDDSQ) was performed and reliability, validity, sensitivity and specificity were analyzed to provide a simple, Effective tool. 【Methods】 Autism, cerebral palsy and mental retardation were selected. A total of 639 children aged from 12 to 47 and 727 children aged from 4 to 18 years old were selected as study subjects to test the reliability and validity of PDDSQ Chinese version. 【Results】 Using exploratory factor analysis, two factors were extracted from two age groups and the confirmatory factor analysis of structural equation model was performed using AMOS 17.0. The results showed that the proposed method had good validity. The Cronbach’s alpha coefficients of the internal consistency reliability of the two age groups were 0.903 and 0.925 respectively, the half-confidence scores were 0.818 and 0.861 respectively, and the reliability of the test-retest after one month was 0.707 and 0.641 respectively. 【Conclusion】 The revised PDDSQ Chinese version has good reliability and validity and is suitable for China to carry out screening of people with autism.
