The Japanese Maternal Breastfeeding Evaluation Scale (JMBFES) was developed in 2013 based on the original Maternal Breastfeeding Evaluation Scale (MBFES). Mothers' abilities to incorporate breastfeeding into their daily life may influence their decision to continue or discontinue to breastfeed, but that version of the JMBFES had no questions to measure this important aspect of breastfeeding. Therefore, we sought to improve the JMBFES by incorporating questions measuring "lifestyle compatibility-incompatibility," and we conducted psychometric testing of the improved version.
In this longitudinal study, the revised JMBFES was developed, and its reliability and validity was tested among 215 Japanese mothers. In the first survey, which was done three months after delivery, infant-feeding status and the prenatal intention regarding breastfeeding were measured. In the second survey, which was done two months later, the JMBFES questions were asked along with questions regarding infant-feeding status. We identified items that could be deleted while maintaining high reliability. Using regression models, we examined associations of JMBFES scores with breastfeeding intention and breastfeeding outcomes.
All three subscales in the revised JMBFES had acceptable reliability (alpha >=0.78). The two "lifestyle compatibility-incompatibility" items (one new item and the one that had been deleted previously) belonged to the "potentially negative aspects" subscale. Scores on that subscale were not associated with breastfeeding intention. However, in both surveys, the mothers who were using formula reported more potential difficulties (p<=0.01).
Results of validation testing and reliability testing indicate that the revised JBFEES can be used to measure breastfeeding satisfaction among Japanese mothers.
日本母乳喂养评估量表（JMBFES）于2013年在原始母乳喂养评估量表（MBFES）的基础上开发。母亲将母乳喂养融入日常生活的能力可能会影响她们继续或停止母乳喂养的决定，但该版本的JMBFES没有问题来衡量母乳喂养的这一重要方面。因此，我们试图通过纳入衡量“生活方式兼容性-不兼容性”的问题来改进JMBFES，并对改进版本进行了心理测量测试。
在这项纵向研究中，开发了修订后的JMBFES，并在215名日本母亲中测试了其信度和效度。在产后三个月进行的第一次调查中，测量了婴儿喂养状况和产前母乳喂养意向。在两个月后进行的第二次调查中，除了询问有关婴儿喂养状况的问题外，还询问了JMBFES的问题。我们确定了在保持高信度的同时可以删除的项目。使用回归模型，我们研究了JMBFES得分与母乳喂养意向和母乳喂养结果之间的关联。
修订后的JMBFES的所有三个子量表都具有可接受的信度（α≥0.78）。两个“生活方式兼容性-不兼容性”项目（一个新项目和一个先前已删除的项目）属于“潜在负面影响”子量表。该子量表的得分与母乳喂养意向无关。然而，在两次调查中，使用配方奶的母亲报告的潜在困难更多（p≤0.01）。
验证测试和信度测试结果表明，修订后的JBFEES可用于测量日本母亲的母乳喂养满意度。
