Abstract
Objectives: Among medical students, depression, anxiety, and stress (DAS) are key public wellbeing challenges that require epidemiological research. We aimed to evaluate potential sources of these psychological disturbances and assess the contribution of academic and non-academic life stressors in psychological morbidity among medical students. Methods: This exploratory questionnaire-based survey was conducted in a Saudi Arabian public sector medical college. A total of 231 medical students were enrolled and completed the depression, anxiety, and stress scale-21 (DASS-21) questionnaire. Results: More than half of the medical students, 129 (55.8%), had depression, 106 (45.9%) students had anxiety, and 87 (37.7%) students had stress. Academic achievement was the largest explanatory factor for depression and stress, whereas bodily appearance constituted the largest explanatory factor of anxiety among the study sample. Academic and non-academic stressors score was significantly associated with depression (adjusted Odds Ratio, aOR = 1.13, 95% CI 1.07-1.19), anxiety (aOR = 1.07, 95% CI 1.03-1.12), and stress (aOR = 1.12, 95% CI 1.08-1.17). Conclusions: Medical students have a high incidence of negative emotional states. These negative psychological states were explained by academic achievement and bodily appearance. The studied stressors influenced medical students' psychological wellbeing.
