Introduction. A cognitive model of aetiology of panic disorder assumes that people who experience frequent panic attacks have tendencies to catastrophically interpret normal and benign somatic sensations - as signs of serious illness. This arise the question: is this cognition specific for patients with panic disorder and in what intensity it is present in patients with serious somatic illness and in healthy subjects. Objective. The aim of the study was to ascertain the differences in the frequency and intensity of 'catastrophic' cognitions related to body sensations, and to ascertain the differences in the frequency and intensity of anxiety caused by different body sensations all related to three groups of subjects: a sample of patients with panic disorder, a sample of patients with history of myocardial infarction and a sample of healthy control subjects from general population. Methods. Three samples are observed in the study: A) 53 patients with the diagnosis of panic disorder; B) 25 patients with history of myocardial infarction; and C) 47 healthy controls from general population. The catastrophic cognitions were assessed by the Agoraphobic Cognitions Questionnaire (ACQ) and the Body Sensations Questionnaire (BSQ). These questionnaires assess the catastrophic thoughts associated with panic and agoraphobia (ACQ) and the fear of body sensations (BSQ). All study subjects answered questionnaires items, and the scores of the answers were compared among the groups. Results. The results of the study suggest that: 1) There is no statistical difference in the tendency to catastrophically interpret body sensations and therefore to induce anxiety in the samples of healthy general population and patients with history of myocardial infarction; 2) The patients with panic disorder have a statistically significantly more intensive tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in comparison to the sample of patients with the history of serious somatic illness (myocardial infarction) and the sample of healthy general population. Conclusion. The tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in patients with panic disorder, confirms the cognitive aetiology model of panic disorder and suggests that it should be the focus of prophylactic and therapeutic management of patients with panic disorder.
