工作场所母乳喂养支持量表的汉化及信效度检验

目的翻译并修订工作场所母乳喂养支持量表(WBSS),并检验其信效度。方法采用Brislin翻译模式对WBSS进行翻译-回译;通过文化调试和预试验对量表条目进行修改完善。采用便利抽样法,于2020年6—9月,选取铜仁市妇幼保健院320名儿保科儿童母亲作为研究对象。采用中文版WBSS调查儿童母亲的工作场所母乳喂养支持情况。采用临界比值法和相关系数法进行量表的项目分析;采用内容效度指数(CVI)和探索性因子分析评价量表的效度;采用Cronbach'sα系数、折半信度系数和重测信度系数评价量表的信度。结果中文版WBSS条目水平CVI为0.833~1.000,量表水平的平均CVI为0.958;探索性因子分析共提取3个公因子,累计方差贡献率为57.973%。中文版WBSS的Cronbach'sα系数为0.805,折半信度系数为0.800,重测信度系数为0.948。最终形成的中文版WBSS共包括3个维度(同事支持、环境支持、设施支持)12个条目。结论中文版WBSS具有良好的信度和效度,可以用于工作场所母乳喂养支持状况的评估。

Reliability and validity of the Chinese version of Workplace Breastfeeding Support Scale

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'sαcoefficient,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'sαcoefficient 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.
