The data were analyzed using the statistical package for social sciences version 10.0 software. The analysis involved descriptive analysis of the data. RESULTS AND CONCLUSIONS: A total of 210 of people responded to the questionnaire given to them. Of these, 164 were considered for further analysis as the rest had not provided the complete background information or the questionnaire was not completed. The undergraduate medical students had multiple lacunae in their knowledge toward psychiatry, psychiatric disorders, psychiatric patients and psychiatric treatment. A potential contributory fact could be the neglect of psychiatry as a discipline at the undergraduate level.
