Abstract: 【Objective】 To revise the questionnaire of Pervasive Developmental Disorders Screening Questionnaire,(PDDSQ)(Chinese version),analyze the reliability,validity,sensitivity and specificity of PDDSQ,and supply the simple,convenient and effective tool for the autism screening of large sample size in our country. 【Method】 A total of 639 aged 12~47 months and 727 aged 4~18 years children's (consist of autism,mental retardation/cerebral palsy and normal control) parents were tested to analyze the reliability and validity of the questionnaire. 【Results】 Using exploratory factor analysis to evaluate the Chinese version of the PDDSQ,two factors were selected in each age category,and AMOS 17.0 was used in the confirmatory factor analysis of structure equation models.The results showed a good validity.The alpha reliability coefficients for the total scale of the two ages were 0.903 and 0.925,the split-half reliability coefficients were 0.818 and 0.861,and the 1-month re-test reliability were 0.707 and 0.641. 【Conclusion】 The Chinese version of the PDDSQ shows good validity and reliability for autism screening in China.
