Two questionnaires were chosen (Eysenck Personality Inventory, EPI-A and Bortner questionnaire) and applied to medical students of the 5th year (Charles University, 1st Faculty of Medicine, between 1989 to 2003, N = 2682, including 1565 women) with a reference group of unselected population over 14 years. The followed group of medical students displayed personality and behavioural attributes suitable for their future work.
