A Maternal Breastfeeding Evaluation Scale was developed from categories identified in qualitative research. Content validity was tested according to procedures described by Imle and Atwood and Lynn. A sample of 442 women who had breastfed completed an instrument of 56 Likert-scale items. A retest questionnaire was completed by a subsample of 28 women. Exploratory factor analysis resulted in three factors, accounting for 38.5 percent of the variance: Maternal Enjoyment/Role Attainment (29 percent), Infant Satisfaction/Growth (5 percent), and Lifestyle/Maternal Body Image (4 percent). A revised 30-item MBFES was developed using items loading strongly on these three factors. Cronbach's alphas for the revised scale and subscales were .93, .93, .88, and .80, respectively. Test-retest correlations (n = 28) were .93, .93, .94, and .82, respectively (p < .001 for all).
一种产妇母乳喂养评估量表是根据定性研究中确定的类别编制而成。内容效度按照Imle、Atwood和Lynn所描述的程序进行了检验。442名曾进行母乳喂养的女性样本完成了一份包含56个李克特量表项目的工具。28名女性的子样本完成了复测问卷。探索性因素分析产生了三个因素，占方差的38.5%：产妇享受/角色实现（29%）、婴儿满意度/成长（5%）以及生活方式/产妇身体形象（4%）。利用在这三个因素上负荷较高的项目编制了一份修订后的包含30个条目的MBFES。修订后量表及各分量表的克朗巴哈系数分别为0.93、0.93、0.88和0.80。复测相关性（n = 28）分别为0.93、0.93、0.94和0.82（所有p值均<0.001）。
