The Iowa Infant Feeding Attitude Scale (IIFAS; de la Mora, Russell, Dungy, Losch, & Dusdieker, 1998) can be utilized to measure maternal attitudes toward infant feeding methods (e.g., breast-feeding, formula-feeding). The scale was designed to cover various dimensions of infant feeding. For example, questions were written concerning the costs of infant feeding (e.g., “Formula feeding is more expensive than breast-feeding”), nutrition (e.g., “Breast milk is the ideal food for babies”), convenience (e.g., “Breast-feeding interferes with a couple’s sexual relationship”), and infant bonding (e.g., “Breast-feeding increases mother-infant bonding”). Respondents are asked to indicate the extent to which they agree with each statement, on a five-point Likert scale ranging from “strongly disagree” to “strongly agree.” The scale consists of 17 items, with items worded so that approximately half of the questions are favorable toward breast-feeding and the remaining questions favorable toward formula-feeding. These scores are then computed so that a high score reflects a preference for breast-feeding.
Studies conducted by de la Mora et al. (1998) support the reliability and validity of the IIFAS in assessing attitudes towards infant feeding methods. Women in these studies either breast-fed (e.g. exclusively or partially) or formula-fed their infants. The IIFAS appears to be very reliable, with Cronbach’s alpha ranging from .85 to .86. The scale also appears to provide a valid assessment of attitudes toward infant feeding method. It was able to differentiate between women who planned to breast-feed their infants versus women who planned to formula-feed their infants.
