The Comparison of Psychological Characteristics Between Undergraduate and Graduate Medical Students / 신경정신의학

ABSTRACT

OBJECTIVES: The conversion of medical colleges into medical schools has been attempted by the Korean government since 2005. The aim of this study was to compare psychological characteristics of undergraduate and graduate medical students before and after changes in the medical educational system. METHODS: Four hundred-and-twenty-eight medical students participated in this study; 247 were undergraduates and 181 were graduate students. The participants completed psychological assessments including the Minnesota Multiphasic Personality Inventory (MMPI), the Symptom Checklist-90-Revision (SCL-90-R), the Beck Depression Inventory (BDI), and the Alexithymia Scale. RESULTS: Overall, undergraduate medical students demonstrated significantly higher scores than the graduate medical student on three of MMPI subscales (F, depression, and social introversion) and two of SCL-90-R subscales (somatization and obsessive-compulsive). When comparing the four groups (male undergraduate, female undergraduate, male graduate, female graduate) using analysis of covariance and controlling for age as a covariate, there were significant differences between male graduate and male undergraduate medical students in the same subscales except somatization, whereas there were no significant differences between female groups. CONCLUSION: These findings suggest that male graduate medical students may have better mental health states and less psychological problems than undergraduate medical students even after controlling for age. However, these differences were not found between female groups. Although every score of all items was within normal range regardless of group, distinctive differences between male graduate and undergraduate students were revealed for some psychological profiles such as depression, social introversion, and obsessive-compulsive traits.
