摘要:A cross-sectional study was carried out, aimed to establish the academic burnout, engagement, and mental health changes in engineering and health sciences students at the beginning and at the end of the semester studied. 145 students between ages 16-36, from a Colombian public university, were the participants evaluated from February to June in 2015 by the Maslach Burnout Inventory Student Survey, Utrecht Work Engagement Scale Symptom Inventory 90-R. The results indicate increase in exhaustion and cynicism, and reduction on dedication and depression during the semester. Burnout is more severe in engineering at the beginning of the semester, while the engagement is greater in health sciences. It is concluded that there are changes in exhaustion raise (exhaustion-cynicism), decrease in engagement (dedication), and mental health, especially in the symptoms of depression; in addition, there is the distinction of burnout-engagement in engineering and health sciences at the beginning of the semester.
