The purpose of this study was to develop and evaluate breastfeeding effectiveness scale to measure effectiveness of breastfeeding for mothers in the early postpartum period.
A conceptual framework was constructed from properties of effective breastfeeding (Yang and Seo, 2011), and item construction was derived from literature review and analysis of the data along with interviews with breastfeeding mothers. Content validity was tested by experts. Each item was scored on a five-point Likert scale. The preliminary questionnaire was administered to 248 breastfeeding mothers. Data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's α.
From the factor analysis, 20 items in seven factors were derived. The factors were identified as mother's satisfaction, suckling, assurance of milk quantity, infant's satisfaction, latching on, infant's feeding desire, and breastfeeding positioning. The seven factors explained 65.1% of total variance, Cronbach's α of the total items was .83 and the factors ranged from .44 to .75.
Results of this study suggest that breastfeeding effectiveness scale is a reliable and valid instrument to measure breastfeeding effectiveness of mothers in the early postpartum period.
