Objectives. To assess the level of aggressiveness, aggression control and direction, as well as specific aggressive behaviors in patients diagnosed with functional dyspepsia or irritable bowel syndrome.
Method. Participants in the study were 50 patients (19 men and 31 women, mean age 37.7 years) diagnosed with either functional dyspepsia or the irritable bowel syndrome. They were examined using the Psychological Inventory of Aggression Syndrome (IPSA).
Results. In both groups of patients, with functional dyspepsia (FD) and irritable bowel syndrome (IBS), aggressiveness intensity was low. A significant intergroup difference was found as regards aggressive behavior control - high in FD patients and average in those with IBS (U = 198.00; p<0.05). No significant relationship was noted between the intensity of aggressive behaviors studied and the patient's clinical diagnosis. In both groups the levels of self-aggression, latent aggression and outward aggression were low.
Conclusions. Patients with functional disorders of the digestive system are characterized by a low aggression intensity. The level of aggressive behavior control differentiated between patients diagnosed with functional dyspepsia and those with irritable bowel syndrome.
