Undergraduate medical students run the risk of experiencing burnout throughout their training. The literature has demonstrated that strengthening emotional intelligence and understanding the authentic self has implications for well-being. This non-experimental, cross-sectional study aimed to test the relationship between emotional intelligence, authenticity, and subjective well-being of undergraduate medical students at an academic health center in Texas. A convenience sample of undergraduate medical students at a single research site in Texas was used. Participants varied in gender, race, age, and year of training. Medical students who participated in the study completed an electronic questionnaire that captured demographic information and measured emotional intelligence, authenticity, and well-being. Using a correlational research design, findings from the aggregated data supported a significant relationship between emotional intelligence and authenticity for well-being, while controlling for demographic variables. Additionally, the interaction effect of emotional intelligence and authenticity also had significant, and marginally higher, well-being results. Findings from this study offer implications for practice and recommended interventions. [The dissertation citations contained here are published with the permission of ProQuest LLC.
