目的编制适合基层保健医师使用的婴儿社会性反应父母评价问卷，并进行信效度评价。方法通过文献复习、专家咨询、家长访谈等方法制定婴儿社会性反应问卷初稿，而后在1200名婴儿中实施调查，通过项目分析、探索性因子分析和验证性因子分析确定问卷最终结构。对80名研究对象在3～5d后进行了重测。结果3、6、9、12月龄量表的重测信度分别为0．746、0．773、0．916、0．782，评分者问信度分别为0．719、0．728、0．943和0．790，总量表的Cronbach’“系数分别为0．595、0．607、0．625、0．624。3、6、9、12月龄问卷因予分析分别提取1、3、3、2个公因子，累积方差贡献率分别为80．1％、51．2％、46．4％、40．8％；验证性因子分析显示，模型拟合良好；母亲不同特征组问婴儿社会性反应得分差异有统计学意义，提示问卷区分效度良好。结论婴儿社会性反应问卷结构清晰，信效度指标符合测量学要求，可作为婴儿社会性发育筛查工具。

英文摘要：

Objective To develop and validate a parent-completed Infant Sociality Performance Questionnaire suitable for primary care physicians. 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,ex- plora＇tory factor analysis （EFA） and confirmatory factor analysis （CFA）. Eighty infants were re-tested with the question- naire 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 a 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 ques- tionnaire showed that 1 common factors,3 common factors,3 common factors and 2 common factors were abstracted respec- tively, 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.
