Personality Traits of Students of Helping and Non-Helping Professions: Case-Based Reasoning Approach

Personality traits are very important in choosing future profession because most professions require certain skills that are related to certain personality traits. The aim of our research was to determine which personality traits contribute the most to the distinction between the students of different professions, e.g. helping and non-helping professions. On a sample of 356 students, of which 216 study helping professions, Big Five Plus Two (BF+2) personality inventory was applied. For obtained data, the classification accuracies were tested with different combinations of 184 items and 18 subtraits of the BF+2 using Case based reasoning classifier. Results showed that the best accuracy had the set of all 18 subtraits and this set outperformed the classification of every combination of subtraits or items.
