To develop the environment scale of unintentional injury in the home for children aged 0-6 years living in urban area of China, and test its validity and reliability. The content of the environment scale was established through the literature review, expert consultation and pilot study. A total of 1 104 children aged 0-6 years in urban area of Changsha were enrolled in this study by using a multi-stage stratified cluster random sampling method. The questionnaire was used to collect the basic information of children, the incidence of unintentional injury and the status of home environment. The reliability of the scale was tested by using Cronbach's α coefficient and split-half reliability coefficient. The content validity and construct validity were tested by using Pearson correlation analysis and factor analysis. All children were divided into two groups according to the incidence of unintentional injury in the home and the discrimination validity of the scale was tested by using -test. The scale had 54 items in 6 dimensions. The number of eligible questionnaires was 1 074, including 554 (51.6%) from boys and 519 (48.3%) from children under 3 years old. The incidence rate of unintentional injury and in-home injury was 18.34% (197 children) and 10.71% (115 children). The internal consistency reliability (Cronbach's α) coefficient for the scale was 0.87 and the split-efficacy reliability coefficient was 0.82, both meeting the standard of reliability above 0.70. The Pearson correlation coefficient between each dimension and the whole scale ranged from 0.53 to 0.84 (all values <0.001). The common factor cumulative variance contribution rate of the scale was 58.34%. There were 54 items with factor loadings greater than 0.30. The root mean square error of approximation, comparative fit index and goodness-of-fit index were 0.07, 0.61 and 0.71, respectively. The score of scale in children with injury was significantly higher than that in children without injury (0.022). The validity and reliability of the environment scale for unintentional injury in the home for children aged 0-6 years old in the urban area of China are good.
研制适合我国城市0～6岁儿童家庭意外伤害环境量表，并检验其信效度。通过文献回顾、专家咨询及预试验确定量表内容。采用多阶段分层整群随机抽样方法，选取长沙市城区1 104名0～6岁儿童作为研究对象，采用问卷调查法收集儿童基本信息、意外伤害发生情况及家庭环境状况。采用Cronbach's α系数和分半信度系数检验量表的信度，采用Pearson相关分析和因子分析检验量表的内容效度和结构效度。根据家庭意外伤害发生情况将所有儿童分为两组，采用t检验检验量表的区分效度。该量表共54个条目，分6个维度。有效问卷1 074份，其中男童554份（51.6%），3岁及以下儿童519份（48.3%）。意外伤害发生率为18.34%（197名儿童），家庭内伤害发生率为10.71%（115名儿童）。量表的内部一致性信度（Cronbach's α）系数为0.87，分半信度系数为0.82，均达到信度标准（>0.70）。各维度与总量表的Pearson相关系数在0.53～0.84之间（均P<0.001）。量表的共同因子累积方差贡献率为58.34%，有54个条目因子载荷大于等于0.30。近似误差均方根、比较拟合指数及拟合优度指数分别为0.07、0.61和0.71。有伤害儿童的量表得分显著高于无伤害儿童（P=0.022）。我国城市0～6岁儿童家庭意外伤害环境量表的信效度良好。
