RESUMO
PURPOSE: The first year of life is known as the "Oral Stage" in psychosexual development theory. We investigated the impact of psychosexual development theory-based breastfeeding education on primiparous mothers' feeding attitudes and behaviors. DESIGN AND METHODS: We conducted this randomized controlled study at a baby-friendly hospital between December 2022 and July 2023. Participants were randomized to intervention (n = 21) and control (n = 19) groups. All participants received the same standard discharge education in the hospital, and the intervention group received additional psychosexual development theory-based breastfeeding education. Data collection for both groups involved conducting face-to-face and telephone interviews, utilizing the Personal Information Form, IOWA Infant Feeding Attitude Scale (IIFAS), Breastfeeding Form, and Psychosexual Theory and Breastfeeding Knowledge Form. The study was recorded in the Clinicaltrials.gov PRS system (ID: NCT06009120). RESULTS: The mean IIFAS score of mothers in the intervention group was 76.23 ± 4.10, while mothers in the control group was 66.31 ± 5.72, which was statistically significant (p < .001). Additionally, mothers in the intervention group fed their babies with formula less often on days 5 to 8 after birth (p < .05) and breastfed more frequently and for longer durations on days 3 to 8 compared to the control group (p < .05). CONCLUSIONS: Psychosexual development theory-based breastfeeding education reduced the use of formula, increased mothers' attitudes towards breastfeeding, and increased the duration and frequency of breastfeeding. PRACTICE IMPLICATION: Integrating psychosexual development theory-based breastfeeding education into routine maternal and infant care may enhance breastfeeding attitudes and practices, potentially improving infant feeding outcomes.
