Only a minority of infants are exclusively breastfed for the recommended 6 months postpartum. Breast-feeding self-efficacy is a mother's confidence in her ability to breastfeed and is predictive of breastfeeding behaviors. The Prenatal Breast-feeding Self-efficacy Scale (PBSES) was developed among English-speaking mothers to measure breastfeeding self-efficacy before delivery.
To translate the PBSES into Spanish and assess its psychometric properties.
Reliability and validity assessment.
A public hospital in Yecla, Spain.
A convenience sample of 234 pregnant women in their third trimester of pregnancy.
The PBSES was translated into Spanish using forward and back translation. A battery of self-administered questionnaires was completed by participants, including a questionnaire on sociodemographic variables, breastfeeding experience and intention, as well as the Spanish version of the PBSES. Also, data on exclusive breastfeeding at discharge were collected from hospital database. Dimensional structure, internal consistency and construct validity of the Spanish version of PBSES were assessed.
Confirmatory factor analysis suggested the presence of one construct, self-efficacy, with four dimensions or latent variables. Cronbach's alpha coefficient for internal consistency was 0.91. Response patterns based on decision to breastfeed during pregnancy provided evidence of construct validity. In addition, the scores of the Spanish version of the PBSES significantly predicted exclusive breastfeeding at discharge.
The Spanish version of PBSES shows evidences of reliability, and contrasting group and predictive validity. Confirmatory factor analysis indicated marginal fit and further studies are needed to provide new evidence on the structure of the scale. The Spanish version of the PBSES can be considered a reliable measure and shows validity evidences.
只有少数婴儿在产后 6 个月内完全接受母乳喂养。母乳喂养自我效能感是母亲对自己母乳喂养能力的信心，是母乳喂养行为的预测指标。产前母乳喂养自我效能感量表（PBSES）是在英语母语母亲中开发的，用于在分娩前测量母乳喂养自我效能感。
将 PBSES 翻译成西班牙语，并评估其心理测量学特性。
可靠性和有效性评估。
西班牙赫克拉的一家公立医院。
234 名处于妊娠晚期的孕妇的便利样本。
使用正向和反向翻译将 PBSES 翻译成西班牙语。参与者完成了一系列自我管理的问卷，包括社会人口统计学变量、母乳喂养经验和意图的问卷，以及西班牙语版的 PBSES。此外，还从医院数据库中收集了关于出院时纯母乳喂养的数据。评估了西班牙语版 PBSES 的维度结构、内部一致性和构念效度。
验证性因素分析表明存在一个结构，即自我效能感，有四个维度或潜在变量。内部一致性的克朗巴赫α系数为 0.91。基于怀孕期间是否决定母乳喂养的反应模式提供了构念效度的证据。此外，西班牙语版 PBSES 的得分显著预测了出院时的纯母乳喂养。
西班牙语版 PBSES 具有可靠性和对比组及预测有效性的证据。验证性因素分析表明存在边缘拟合，需要进一步研究提供该量表结构的新证据。西班牙语版 PBSES 可以被认为是一种可靠的测量方法，并且具有有效性证据。
