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1 200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,评分者间信度分别为0.719、0.728、0.943和0.790,总量表的Cronbach’α系数分别为0.595、0.607、0.625、0.624。3、6、9、12月龄问卷因子分析分别提取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;母亲不同特征组间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。
Objective To prepare a questionnaire for parents’ evaluation of social reactions in infants who are suitable for primary care physicians and evaluate their reliability and validity. Methods The first draft of social questionnaire for infants was made through literature review, expert consultation and interview with parents, and then the survey was conducted among 1,200 infants. The final structure of the questionnaire was determined through project analysis, exploratory factor analysis and confirmatory factor analysis. Eighty subjects were retested 3 to 5 days later. Results The test-retest reliability of 3, 6, 9 and 12 months old scale were 0.746,0.773,0.916 and 0.782, respectively. The reliability of the scorers were 0.719,0.728,0.943 and 0.790 respectively. The Cronbach’α coefficient Respectively, we extracted 1, 3, 3 and 2 common factors respectively for the questionnaires of 0. 595, 0. 607, 0. 625 and 0 624. 3, 6, 9 and 12 months with the cumulative variance contribution rates of 80.1%, 51.2% and 46.4% 40.8%. The confirmatory factor analysis showed that the model fitted well. There was significant difference in the scores of social reaction among infants in different mothers’ mothers, suggesting that the questionnaire had good discriminative validity. Conclusion The structure of the questionnaire of social response in infants is clear, and the reliability and validity index meets the requirements of surveying. It can be used as a screening tool for social development of infants.
