Prenatal Lactation-Focused Motivational Interviewing

• Recruitment efforts will be made in the community via advertisements, online advertisements (e.g., Craigslist, Facebook), and in-person at various clinics and health fairs in the geographic area.
• Prospective participants will contact the investigators via email or by calling the study phone number listed on the advertisements or verbally expressing interest in-person.
• Once a participant indicates interest by contacting study personnel, a 5-minute screening interview will be conducted with the prospective participant using the screening questionnaire to ensure eligibility criteria are met. For those who do not qualify or agree to participate, the age and reason for non-qualification or declination to participate will be recorded; any other data will be destroyed by shredding or electronic shredding. For those who do qualify, name and contact information will be kept confidential and maintained in a locked room.
• Participants will be asked to rate on a scale of -10 to +10 about the certainty that the participants will provide exclusive breastmilk to the babies for first six months. Responses from this item will be used as the covariate in the covariate adaptive randomization technique.
• Eligible subjects will be invited to participate in the study, either in an exam room at West Virginia University's Family Medicine's clinic, participant's home, private room in the Quin Curtis Center for Psychological Services, or in another agreed-upon community location (e.g., church). The location of the study procedures is chosen by the participant.
• At the start of this session, participants will be given an overview of the study, and the researcher will go over the consent form with the participant.
• Following consent procedures, video-recording will begin, and all participants will complete the prenatal interview. After this interview, participants will complete five self-report measures, which include the Infant Feeding Knowledge Form, the Iowa Infant Feeding Attitudes Scale, Brief Breastfeeding Attitudes Questions, Perinatal Anxiety Screening Scale, and the Knowledge of Infant Development Inventory.
• Intervention

• Participants assigned to the MI condition will receive an approximately 45 minute intervention provided a masters-level supervised psychologist with training in Motivational Interviewing.
