摘要：

目的对母乳喂养动机量表（Breastfeeding Motivation Scale,BMS）进行汉化并检验其信效度。方法按照Brislin的翻译模型对原量表进行直译与回译,经过文化调适及预测试后,确定中文版BMS。于2020年12月—2021年5月,采取便利抽样法选取南京市某三级甲等医院的312名初产妇进行问卷调查,评价量表的信效度;于2021年6月—10月,采取便利抽样法选取270名初产妇发放问卷,进行验证性因子分析。结果中文版BMS共4个维度、24个条目,分别为享受（8个条目）、联结和母亲自我认知（8个条目）、重要的他人压力（4个条目）、实用性需求（4个条目）。中文版BMS条目水平的内容效度指数为0.830~1.000,量表水平的内容效度指数为0.901。各维度的Cronbach’s α系数为0.709~0.934,分半信度为0.717~0.930;验证性因子分析结果显示,模型适配度良好。结论中文版BMS具有良好的信效度,可用于对母乳喂养动机进行评估,提升母乳喂养积极心理。

Abstract:

Objective The purpose is to translate the Breastfeeding Motivation Scale（BMS） based on Self-Determination Theory,and to test its reliability and validity. Methods According to Brislin model,the original scale was translated and back-translated;after cultural adjustment and pretest,the Chinese version of the scale was determined. 312 primiparas were investigated by convenience sampling method in a tertiary hospital in Nanjing to evaluate the reliability and validity of the scale from December 2020 to May 2021. 270 primiparas were investigated by convenience sampling method for confirmatory factor analysis from June to October 2021. Results The Chinese version of BMS was divided into 4 dimensions with a total of 24 items,namely enjoyment（with 8 items）,bonding with the baby and maternal self-perception（with 8 items）,pressure from significant others（with 4 items）,and instrumental needs（with 4 items）. The item level content validity index of the Chinese BMS was 0.830~1.000;the level validity index was 0.901. The scale did not calculate the total score,and the Cronbach’s α coefficient of each dimension was 0.709~0.934;the split-half reliability was 0.717~0.930. Confirmatory factor analysis showed that the scale had good construct validity. Conclusion The Chinese version of BMS has good reliability and validity,and it can be used for breastfeeding motivation assessment and nursing research,which can improve the positive psychology of breastfeeding.
