Abstract Health literacy (HL) concerns not only individuals but also health systems and health professionals. Most of the literature on HL has focused on patient factors, with little emphasis on the communication skills and practices of health professionals. Training is needed at all levels to understand the concept of HL and its impact on health inequalities. This study is an intervention study. Data were collected from 29 students taking the third year elective course at the Faculty of Medicine through an online survey. The survey consists of 40 questions aimed at assessing the demographic characteristics of the participants, the TSOY-32 Scale and some factors affecting HL. During the training period, role-play scenarios were played to teach the importance of HL, sample videos were watched to evaluate physician-patient communication, and case studies were conducted. The mean pre-test TSOY-32 scale score of the participants was 32.8±5.8. The mean post-test TSOY-32 scale score was 36.4±7.1. There was a significant difference between pretest and posttest groups in terms of TSOY-32 scale score (p = 0.033). Health professionals often overestimate patients’ HL levels and do not have sufficient competence to effectively manage limited HL. These gaps need to be addressed through the curricula of medical schools and specialties. Key messages • Training on health literacy improves medical students’ communication skills, bridging gaps in patient care. • Addressing health literacy in medical training enhances patient-doctor communication, vital for quality care.
