In assessing the meaningful cognitive-behavioural dimensions in anorexia nervosa and bulimia nervosa the Eating Disorder Inventory Questionnaire plays an important role. In the group of 401 medical students of Jagiellonian University (group I) and 459 pupils (group II) from the secondary schools in Krakow the eight subscales of EDI Questionnaire were performed. The six steps frequency score scale was applied. Mean scores for two compared groups were differentiated in particular subscales: Drive for thinness (3.2 - gr. I / 3.05 - gr. II), Bulimia (1.48 - 1 / 1.27 - II), Body dissatisfaction (7.7 -1 / 6.98 - II), Ineffectiveness ( 3.76 - 1 / 3.27 - II), Perfectionism (4.58 -1 / 4.11 - II), Interpersonal distrust ( 4.46 - 1 / 4.56 - II), Intercepts awareness ( 3.72 - I / 3.35 - II) and Maturity fears ( 5.03 - gr. I / 5.82 - gr. II).
