Many new mothers discontinue breastfeeding prematurely. Researchers have shown that maternal confidence is an important factor in the continuation of breastfeeding. The purpose of this methodological study was to develop and conduct preliminary psychometric assessment of an instrument to measure confidence in new breastfeeding mothers. Using self-efficacy theory as a conceptual framework, the Breastfeeding Self-Efficacy Scale (BSES) was developed and content validity was judged by a panel of experts and through interviews with experienced breastfeeding mothers. Following a pilot test, the revised BSES was assessed with 130 in-hospital breastfeeding mothers for reliability and validity, including internal consistency, principal components factor analysis, comparison of contrasted groups, and correlations with measures of similar constructs. Support for predictive validity was demonstrated with positive correlations between BSES scores and infant feeding patterns at 6 weeks postpartum. Following further testing, this instrument may be used to identify new mothers with low breastfeeding confidence who are at high risk to prematurely discontinue breastfeeding.
许多新妈妈过早停止母乳喂养。研究人员表明，母亲的信心是持续母乳喂养的一个重要因素。这项方法学研究的目的是开发并对一种测量新妈妈母乳喂养信心的工具进行初步心理测量评估。以自我效能理论为概念框架，开发了母乳喂养自我效能量表（BSES），并由专家小组和通过对有经验的母乳喂养妈妈的访谈来判断内容效度。在进行预试验后，对130名住院的母乳喂养妈妈进行了修订后的BSES的可靠性和有效性评估，包括内部一致性、主成分因子分析、对比组比较以及与类似结构测量指标的相关性。产后6周时BSES得分与婴儿喂养模式之间的正相关证明了预测效度。经过进一步测试后，该工具可用于识别母乳喂养信心低且过早停止母乳喂养风险高的新妈妈。
