Objectives：The purpose of this study is to assess the relationship between the psychological characteristics and academic performance of medical students and investigate the factors that can predict academic performance.
Methods：We analyzed the mental health survey of medical students data conducted by one medical school in June 2013. Three-hundred thirty students were examined sociodemographic backgrounds and the Minnesota Multiphasic Personality Inventory?2(MMPI-2) questionnaire. Then, we compared it with grade point average of the same year. Unlike previous studies, academic performance was converted to T-score in order to correct the different grades.
Results：The results showed that gender had the most powerful predictor of academic performance, where female tudents showed higher academic performance than male students. We used two different set of MMPI-2 scales; clinical scale measuring psychopathology and personality psychopathology five(PSY-5) scale measuring dimensional traits of personality disorders. At the MMPI-2, schizophrenia of the clinical scale and neuroticism of the personality pychopathology five scale were significantly correlated with academic performance. Among six clinical subscales of schizophrenia clinical scale, only motivation and social isolation had significant correlation with academic performance.
Conclusion：Gender, inner and external motivation, social isolation, and neuroticism are found to impact the academic performance.
