Methods A pool of items was created by literature review, Delphi technique, and so on.The original questionnaire was applied in 1 200 normal infants.The final questionnaire was determined through item analysis, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).Eighty infants were re-tested with the questionnaire after three to five days. Results The test-retest reliability of 3-month questionnaire, 6-month questionnaire, 9-month questionnaire, 12-month questionnaire were 0.746, 0.773, 0.916 and 0.782 respectively;their inter-rater reliability were 0.719, 0.728, 0.943 and 0.790 respectively;their cronbach's α coefficient were 0.595, 0.607, 0.625 and 0.624 respectively.The Results of factor analysis of 3-month questionnaire, 6-month questionnaire, 9-month questionnaire and 12-month questionnaire showed that 1 common factors, 3 common factors, 3 common factors and 2 common factors were abstracted respectively, and the cumulative variance contribution rate were 80.1%, 51.2%, 46.4% and 40.8%.CFA Results provided support for the models.The difference among scores of infant sociality performance questionnaire of infants from different groups was significant, which provides evidence for good discriminant validity. Conclusion The structure of the questionnaire is clear, and it bears satisfactory psychometric properties suggesting that this instrument could be served as a developmental screening tool for infant.
