Objective: The purpose of this pilot study is to evaluate the effects of using motivational interviewing [MI] compared to usual care to promote sustained breastfeeding.
Design: An experimental design with repeated measures will be used in this study. Subjects will be randomly assigned to either MI group or a usual care group.
Sample: A sample size of 40 (20/group) primiparous mothers will be recruited from the population in a regional medical center in rural Nebraska.
Intervention and Outcome Variables: The primary aim of the study is to evaluate the effects of the MI intervention compared to usual care on sustained breastfeeding (# of days of breastfeeding) for 6months. Oligosaccharides in infant feces and infant test weights will validate sustained breastfeeding. The secondary aims include comparing the differences between MI and usual care groups in self-efficacy for breastfeeding and intention to sustain breastfeeding for the recommended 6 months. Another aim of the study is to examine the relationship of duration of breastfeeding and self-efficacy for breastfeeding, intention to breastfeed, and infant health outcomes.
Methods: To evaluate the effect of the proposed intervention on sustained breastfeeding for six months, survival analysis will be used. Descriptive statistics for the continuous variables of the biological and physiologic markers of breastfeeding will be calculated. RM-ANOVA will be used to examine the differences between the MI intervention and the usual care group in self-efficacy for breastfeeding and intention to sustain breastfeeding. Pearson correlations will be done to examine the relationships among the variables in the latter aim.
Relevance to Nursing: The rationale for the proposed study is that identification of a more efficacious intervention will encourage sustained breastfeeding, increase perceived self-efficacy for breastfeeding, and improve infant respiratory health outcomes.
