Objective: Describe the process (reach, dose delivered, dose received, fidelity, and satisfaction) of a culturally tailored breastfeeding intervention. Target Audience: African American, adolescent pregnant and postpartum mothers ages 16–22 and their mentors. Theory, Prior Research, Rationale: Community-Based Participatory Research approach. Description: The Healthy and Proper Parenting for Youth (HAPPY) breastfeeding curriculum consists of three 1-hour workshops: SMART Goals Matter focusing on setting SMART (Specific, Measurable, Action-oriented, Realistic, Timely) goals since having a breastfeeding goal was an important determinant to intention to breastfeed during curriculum development; Breastfeeding Matters consisting of culturally-tailored breastfeeding videos, discussion and a latching simulation activity; and You Matter consisting of a personality test, stress triggers and stretching as a way to relieve stress to emphasize the need to take care of oneself as a breastfeeding mother. Evaluation: Reach was 48% for SMART Goals Matter, 29% for Breastfeeding Matters and 55% for the You Matter workshops based on 31 participants who were active in the local non-profit organization. Dose delivered were 88%, 92% and 100% for the first, second and third workshop, respectively. Participants who were exposed to the intervention (n = 21) received an average of 59% (14.8 ± 2.2 components) of the intervention components, with an average of 56%, 52%, and 73% for workshops 1, 2, and 3, respectively. Fidelity increased from the first (75%), second (86%) to third (100%) workshop. Out of a 5-point likert scale (1 = disagree to 5 = agree), participants were satisfied with all workshops (5 ± 0), felt comfortable expressing their opinions (4.5 ± 1.4), and felt respected as a person (5 ± 0). Conclusions and Implications: Although fidelity and dose delivered were high for all workshops, there were low participation rates and dose received. Future efforts should focus more on integrating breastfeeding into non-breastfeeding topics to increase participation in this population. Funding: NIFA.
