Abstract:
We study the aggressivity level and its direction in the context of personality, in 36 patients with DUD (23 males and 13 females). We employed 30 patients with chronic disease (15 men with COPD and 15 female with arthrosis) as control groups, in addition to the normal population. The purpose of this investigation is to determinate if suffering or chronicity could determinate psychopathological findings similar to those described in the literature about patients with DUD. The results point out that we can not consider a specific ulcerous personality, but a psychophysiological reaction or psychopathological alterations resulting from a somatic disease, on the other hand the autoaggressivity factor pulsion-inhibition, is the most reliable variable when compared with control groups (p less than 0.05-0.01).
