Abstract:
Objective:To translate and revise the Workplace Breastfeeding Support Scale (WBSS) , and test its reliability and validity.Methods:Brislin translation mode was used to translate and back translate WBSS. The scale items were revised and improved through cultural debugging and pre-tests. From June to September 2020, convenience sampling was used to select 320 mothers of children from the Department of Children Health of Tongren Maternal and Child Health Hospital as the research object. The Chinese version of WBSS was used to investigate the breastfeeding support of the mothers of the children in the workplace. The critical ratio method and the correlation coefficient method were used to analyze the items of the scale, and the content validity index ( CVI) and exploratory factor analysis were used to evaluate the validity of the scale. The Cronbach's α coefficient, split-half reliability coefficient and test-retest reliability coefficient were used to evaluate the reliability of the scale. Results:The item-level CVI of the Chinese version of WBSS was from 0.833 to 1.000, and the average scale-level CVI of the scale was 0.958. The exploratory factor analysis extracted three common factors, and the cumulative variance contribution rate was 57.973%. The Cronbach's α coefficient of the Chinese version of WBSS was 0.805, and the split-half reliability coefficient was 0.800, and the test-retest reliability coefficient was 0.948. The final Chinese version of WBSS included 12 items in three dimensions (colleague support, environmental support, facility support) . Conclusions:The Chinese version of WBSS has good reliability and validity, and can be used to assess the status of breastfeeding support in the workplace.
