A study by Azza Ahmed in 2009 looked to see if there would be an increase in breastfeeding by mothers of preterm infants when exposed to a breastfeeding educational program guided by SCT. Sixty mothers were randomly assigned to either participate in the program or they were given routine care. The program consisted of SCT strategies that touched on all three SCT determinants: personal – showing models performing breastfeeding correctly to improve self-efficacy, behavioral –weekly check-ins for three months reinforced participants' skills, environmental – mothers were given an observational checklist to make sure they successfully completed the behavior. The author found that mothers exposed to the program showed significant improvement in their breastfeeding skills, were more likely to exclusively breastfeed, and had fewer problems then the mothers who were not exposed to the educational program.
