Abstract: Objective To develop a Childhood Obesity Health Literacy Scale (Parental Edition),and to examine the reliability and validity of the scale. Methods Based on the connotation of health literacy and the content of ending childhood obesity from WHO,the item pool of the Health Literacy Scale was designed. The scale was then administered to three elementary schools students′ parents for pre-investigation in Hefei. The validity of the scale was examined by using exploratory factor analysis and confirmatory factor analysis,and the reliability indexes of the scale and the subscales were assessed by internal consistency. Results Totally 2 170 elementary schools students′ parents were investigated in this survey. And the scale finally formed and contained 29 items after screening the items by sensibility analysis,representative analysis,independence analysis and Cronbach′s alpha coefficient. Exploratory factor analysis identified five subscales. Based on confirmatory factor analysis,the items were grouped into five subscales on health concept,including health consciousness,health knowledge,health behaviors,health cognitive and operational skills. The indicators of confirmatory factor performed well: root mean square error of approximation(RMSEA) was 0.047,root mean square (RMR) was 0.026,comparative fit index (GFI),normed fit index (NFI),relative fit index (RFI) and comparative fit index (CFI) were close to 1,showing a better model fitting. The Cronbach′s alpha coefficient for the health scale was 0.833 and the corresponding values for the subscales were 0.618~0.866. Conclusions The Childhood Obesity Health Literacy Scale (Parental Edition) is a reliable tool for assessing children′s health literacy with good reliability and validity.

摘要： 目的 编制“儿童肥胖健康素养量表(家长版)”,并评价其信度和效度。方法 依据健康素养内涵,基于世界卫生组织(WHO)提出的终止儿童肥胖相关内容,构建儿童肥胖健康素养量表(家长版)条目池,然后在合肥市小学生家长中进行调查,应用探索性因子分析和验证性因子分析对量表的效度进行检验,应用内部一致性对量表信度进行检验。结果 本次研究共有2 170名小学生家长参与调查,通过敏感性分析、代表性分析、独立性分析及Cronbach′s α系数进行条目筛选,再通过探索性因子分析和验证性因子分析,最终形成29个条目的儿童肥胖健康素养量表(家长版),量表构建成为健康意识、健康知识、健康行为、健康认知及操作技能5个维度。验证性因子分析得到近似误差均方根(root mean square error of approximation,RMSEA)为0.047,残差均方根(root of the mean square residual,RMR)为0.026,拟合优度指数(goodness-of-fit index,GFI)、标准拟合指数(normed fit index,NFI)、相对拟合指数(relative fit index,RFI)和比较拟合指数(comparative fit index,CFI)均接近1,显示模型拟合较好。量表的Cronbach′s α系数为0.833,问卷各维度的Cronbach′s α系数在0.618~0.866之间。结论 所编制的儿童肥胖健康素养量表(家长版)具有较好的信度和效度。
