Background: Limited knowledge, negative beliefs, and lack of sufficient breastfeeding promotion and support by physicians contribute to global suboptimal breastfeeding rates. Formal medical education is well-known to influence future physicians’ knowledge, beliefs, and medical practice. However, less understood is the influence of social networks and processes on the exchange and diffusion of knowledge and practices related to breastfeeding. Objectives: We selected the underserved and under-supported public medical school in Lebanon to examine the social side of medical education. Our objectives were to assess knowledge, beliefs, and self-efficacy related to breastfeeding promotion and support among interns and residents. We also examined the social ecosystem surrounding these students concerning the exchange of breastfeeding knowledge. Design: All data were collected during one study visit per participant. First, an interview-administered structured survey was used to assess beliefs, perceived knowledge, basic breastfeeding knowledge, and self-efficacy related to breastfeeding among n = 70 medical interns and residents. Then, social network data were collected during a semi-structured interview and analyzed using an ego-network approach. All interviews were voice-recorded, transcribed, coded, and thematically analyzed. Descriptive statistics were used to analyze quantitative survey and social network results. Results: Although interns and residents had positive beliefs about breastfeeding benefits, they had limited knowledge and low self-efficacy related to the psychosocial and clinical aspects of breastfeeding promotion and support. They did not seem to have a well-connected professional network around breastfeeding knowledge and practices. Several tended to rely on their informal/non-professional network, such as their mothers, partners, and sisters, for knowledge and practice. Conclusions: Our work using breastfeeding as an exemplary case suggests there is a role for better attending to the beliefs of medical students as well as to the social side of medical education. Future studies can use social network theory to help identify and address influences on medical education outcomes.

The well-being of teachers and preservice teachers has been a topic extensively explored through the lens of burnout and stress. Despite its manifold benefits, few studies have explored PST well-being through the lens of subjective well-being. Grounding our study in positive psychology, we explore the relationships between preservice teachers’ subjective well-being, program sense of belonging, relational trust, and self-efficacy. Our participants included 63 multiple- and single-subject preservice teachers in a major university teacher education program in the western United States. They were surveyed in May 2019 in the final month of completing their program. We found that sense of belonging, relational trust, and self-efficacy individually are positively associated with well-being. A mediation analysis revealed that the relationship between relational trust and subjective well-being is mediated by program sense of belonging, which may indicate the importance of cohesion in a cohort-based teacher education program.
