This study examines the influence of behavior modification interventions on the self-efficacy and self-esteem of undergraduate college students during their transition to higher education. Participants engage in a behavior modification assignment, and their experiences are assessed through pre- and post-surveys and reflective inquiry responses. Through a mixed-methods approach, the research sheds light on how behavior modification strategies empower students to adopt physical and mental health habits, with the potential to enhance their psychological well-being and academic success. This study contributes to a deeper understanding of effective interventions to promote undergraduate well-being within educational contexts.
