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.
