RESUMO
BACKGROUND: Medical students feel a significant amount of stress due to a variety of factors. Few studies have explored the relative size of these various stressors to identify which are most important. This study was undertaken to quantify the magnitude of various sources of stress among students of a medical college at Kolkata, West Bengal, and also to assess the reliability of Medical Students' Stressor Questionnaire (MSSQ-40) in this context. METHODS: We evaluated the degree of stress along various dimensions using the MSSQ-40, a scale to measure stress among medical students that has been validated in other countries. Differences in stress and its causal factors were analyzed across demographic subgroups. The reliability of the MSSQ-40 was evaluated using Cronbach's alpha. RESULTS: The overall prevalence of stress was 91.1% and the vast majority of students (94.9%) were stressed due to academic reasons. Academic related stress was found to be higher among students who are not conversant with the local language, experienced a change in medium of teaching from secondary school to medical school, and resided in a hostel. The MSSQ-40 in general, and its academic-related stress domain specifically, were found to be reliable in our setting. DISCUSSION: Early detection and remedying stressors will help to build physical and mental health in medical students. Language training early during the medical course might reduce academic stress among our students. Further studies should relate individuals' stress with their academic performance.
