产科医护人员母乳喂养知信行调查量表的研制及信效度检验

Development and reliability and validity test of breastfeeding knowledge-belief-practice survey scale for obstetric medical staff

目的编制适合产科医护人员母乳喂养知信行调查量表,并对其进行信效度检验。方法通过文献查阅、质性访谈、专家咨询和预调查,在知信行理论的基础上形成初量表。于2019年5月—8月选择广东省5所三级甲等和2所二级甲等产科医护人员430名进行调查,对量表进行信效度检验。结果构建的产科医护人员母乳喂养知信行调查量表包含知识、态度和行为3个维度,35个条目,采用Likert 5级评分法。探索性因子分析提取3个公因子,累积方差贡献率为70.574%;验证性因子分析显示该量表各拟合指标都达到适配标准值,具有较好的结构效度;总量表及各维度折半系数分别为0.915、0.954、0.884、0.906;内容效度指标S-CVI为0.95,I-CVI为0.80~1.00;总量表的Cronbach’sα系数为0.978,各维度的Cronbach’sα系数为0.972、0.946、0.944。结论该量表具有较好的信度和效度,可用于产科医护人员母乳喂养知识、态度和行为的调查。

Objective To compile a survey scale suitable for breastfeeding knowledge-attitude-practice of obstetric medical staff, and to conduct reliability and validity tests. Methods Through literature review, qualitative interviews, expert consultation and pre-investigation, a preliminary scale was formed on the basis of the theory of knowledge-attitude-practice. From May to August 2019, a total of 430 obstetric medical staff from five third-level first-class and two second-level first-class obstetrics in Guangdong Province were selected for investigation, and the reliability and validity of the scale were tested. Results The constructed obstetric medical staff breastfeeding knowledge, attitude and behavior survey scale contains three dimensions of knowledge, attitude and behavior, 35 items, and uses the Likert five-level scoring method. Exploratory factor analysis extracts three common factors, and the cumulative variance contribution rate was 70.574%;the confirmatory factor analysis showed that all the fitting indexes of the scale reached the fitting standard value, and had good structural validity;the total scale and the reduction coefficient of each dimension were 0.915, 0.954, 0.884, 0.906 respectively;the content validity index S-CVI was 0.95, and I-CVI was 0.80-1.00;the Cronbach’s α coefficient of the total scale was 0.978, and the Cronbach’s α coefficient of each dimension was 0.972, 0.946 and 0.944. Conclusion The scale has good reliability and validity, and can be used to investigate breastfeeding knowledge-attitude-practice of obstetric medical staff.
