Relationship of big five personality traits and future specialty preference among undergraduate medical students: a cross-sectional study

Abstract Background The precise choice of specialty is of paramount importance in a physician’s career. Several factors play a role in deciding the specialty, such as intelligence, motivation, clinical experience, personality, and socioeconomic factors. Our hypothesis is whether personality profiles differ based on specialty choice. Therefore, we investigated the association between personality traits and specialty choice. Results A cross-sectional study was conducted among 379 undergraduate medical students. Big five personality inventory was used to determine the personality traits among medical students. The most chosen speciality among both male and females was Surgery. Comparing the groups depending on their preferred specialties revealed no differences in three of five personality traits of Big five personality inventory. Students who selected psychiatry specialty scored highest on openness (p = 0.007) and lowest on extraversion (p = 0.018), indicating a substantial difference between the traits of extraversion and openness to experience. Conclusions The differences in personality features could not be attributed to a predilection for a particular speciality. However, medical students who scored higher on openness (intellect/imagination) and less on extraversion scales were more likely to choose psychiatric specialty. Numerous other factors affect specialization preference even if there are no differences in personality features between various specialties.
