Development of an exclusive breastfeeding intervention based on the theory of planned behavior for mothers with preterm infants: Study protocol for a mixed methods study

BACKGROUND: Despite the significance and benefits of exclusive breastfeeding, its rate among infants, especially preterm infants, is not optimal. Based on evidence, the mother's attitude toward breastfeeding, the subjective norm, and the mother's perceived behavioral control play a role in initiation and continuation of breastfeeding; so the interventions that consider these factors may be useful for breastfeeding premature infants. The aim of this study is to design and develop an exclusive breastfeeding intervention based on the theory of planned behavior for mothers with preterm infants.MATERIALS AND METHODS: This exploratory, sequential, mixed methods study will be conducted in three phases. In the first phase, a qualitative study will be conducted based on the theory of planed behavior, to describe the exclusive breastfeeding beliefs of the mothers with preterm infants, the barriers to breastfeeding, and to explain the ways to overcome them. Moreover, the items of the Predictors Of Exclusive Breastfeeding Questionnaire are prepared based on the theory of planned behavior. In the second phase, the intervention plan is designed based on the literature review and the findings of the qualitative study, and it is approved by a panel of experts. Additionally, the psychometric properties of the questionnaire are evaluated and confirmed qualitatively and quantitatively. In the third phase, the developed intervention is implemented and evaluated.CONCLUSION: Implementation of supportive educational interventions based on scientific theories can be a step toward improving the rate of onset and continuation of breastfeeding in mothers with preterm infants. Development of interventions based on evidence, identified beliefs, and perceived barriers of the mothers with preterm infants can provide the foundation for more effective interventions according to cultural, social, and religious contexts.
