Vztah k vlastnímu tělu a somatoformní disociace u poruch příjmu potravy

In patients with eating disorders, the distorted perception and negative affective evaluation of one's own body may be but one aspect of a more general disturbance in processing of bodily stimuli. Other manifestations of this hypothetic disturbance may be the insensitivity to fatigue, hunger and physical pain. The mechanism of such abnormality may be associated with the psychopathological process of dissociation. In the current study, the relationship between body image disturbance and somatoform dissociation is explored by two new self-report measures, which have been translated to the Czech language. The Body Attitude Test (BAT) and the Somatoform Dissociation Questionnaire (SDQ-20) have been administered to 57 female patients with eating disorders (30 with anorexia nervosa; 27 with bulimia nervosa). The Czech versions of the two questionnaires showed satisfactory psychometric properties corresponding to the original data. Compared to a control group of 39 healthy wo men, patients with eating disorders scored significantly higher on both somatoform dissociation and pathologic body attitudes. Moreover, the two measures were highly positively associated both within the eating disordered group and across the combined sample. Strongest association was found between somatoform dissociation and the lack of familiarity with one's own body BAT II subscale (r = 0.65). These results suggest that body image disturbance and dissociation in eating disorders are strongly related.
