Objective: To explore the feasibility of using motivational interviewing to promote sustained breastfeeding by increasing a mother’s intent to breastfeed for 6 months and increasing her breastfeeding self-efficacy.
Design: A longitudinal experimental two-group design with repeated measures was selected to explore the feasibility of using motivational interviewing to promote sustained breastfeeding in primiparous mothers.
Setting: Three Western rural community hospital sites.
Participants: Convenience sample of 73 primiparous breastfeeding mothers ranging between the ages of 19 and 38, M= 25 (SD= 4.5).
Main outcome measure: Mothers reported the date of their last day of breastfeeding, defined as any breastfeeding during the previous 24-hour period. Breastfeeding behavior was confirmed at each visit by infant test weights.
Results: The motivational interviewing group (M= 98.1 days, SD= 75.2) breastfed longer than the comparison group (M= 80.7 days, SD= 71.9); however, this difference was not significant, t(69) = 0.991, p= .325, Cohen’s d= 0.24, related to the variability in the sample.
Conclusions: Although not a statistically significant difference, the mean number of days that mothers in the intervention group breastfed was 98 days compared to the mean of 81 days by the comparison group; therefore, motivational interviewing may be useful as a strategy to test in a comprehensive intervention plan.
