目的 对婴儿发育家庭环境支持量表(AHEMD-IS)的信效度进行评价,为早期运动环境的筛查和干预提供有效工具。方法 本研究采用横断面调查的方法,选择上海市分娩量最大的二、三级妇幼保健院以及江苏省盐城市妇幼保健院。招募2014年12月—2015年9月儿保门诊定期体检的婴儿作为研究对象,年龄范围3~11月龄,共纳入研究对象1 250例。信效度评价使用Cronbach′s α系数来测量内在一致性信度,使用Guttman折半系数测量外在一致性信度,使用条目水平内容效度指数(Item-level Content Validity Index,I-CVI)测量内容效度,使用探索性因素分析测量婴儿家庭环境支持量表的结构效度。结果 3~11月龄婴儿发育家庭环境支持量表中文版总体Cronbach′s α系数为0.836,量表26个条目的折半系数为0.515,条目水平的内容效度指数除了第17条目I-CVI得分为0.625,其他条目得分均在0.75~1之间。采用主成分分析法提取4个公因子,累计贡献率为49.27%,分别命名为“活动空间”、“活动多样性”、“大运动玩具”、“精细运动玩具”,与原量表结构符合。结论 婴儿发育家庭环境支持量表达到了基本心理测量学标准。可在研究地区婴儿中使用,作为针对婴儿运动发育环境筛查的有效工具。
Abstract
Objective To assess the reliability and validity of the Affordances in the Home Environment for Motor Development-Infant Scale-Chinese version (AHEMD-IS),so as to provide a valid tool for screening of early motor development environment . Method A cross-sectional survey was conducted in a tertiary and a secondary maternity and children′s health care hospital in Shanghai and a maternity and children′s health care hospital in Yancheng city.Totally 1 250 3 to 11-month-old infants who visited children′s health care clinics regularly for physical examination were recruited from December 2014 to September 2015.Cronbach′s α index for each item was used to determine internal consistency.Guttman half-split coefficient was used to determine external consistency.The content validity was determined by the item-level content validity index (I-CVI).Exploratory factor analysis (EFA) was used to examine the factorial validity of the AHEMD-IS Scale. Results The Cronbach′s alpha value of all items together was 0.836.The Guttman half-split coefficient of AHEMD-IS was 0.515.The I-CVI of AHEMD-IS ranged from 0.75 to 1 except the 17th item.Principal component analysis was conducted to extract four common factors with cumulative contribution rate of 49.27%.The four common factors were named as “activity space”,“variety of stimulation”,“gross-motor toys” and “fine-motor toys” separately,which were consistent with the construction of the original scale. Conclusions Chinese version of AHEMD-IS has good psychometric reliability and validity,and it could be used as a valid tool for motor development in Chinese infants.
