Psychoform and somatoform dissociation among individuals with eating disorders.

Abstract
:

This study analyzed the prevalence of psychoform and somatoform dissociation among individuals with the whole spectrum of eating disorder diagnoses and compared it with ratings from a non-clinical group. The relationship between dissociation and severity of eating disturbance was examined as well as differences between the eating disorder diagnosis groups in extent of dissociation. The validity of a new structural dissociation interview suitable for eating disorder patients was analyzed. Sixty individuals with eating disorder completed three self-report questionnaires: Dissociation Questionnaire Sweden, Somatoform Dissociation Questionnaire and Eating Disorder Examination Questionnaire. The ratings were compared with the scores in a female non-clinical group ( = 245). Twenty patients with eating disorder diagnoses were interviewed with the Interview for Dissociative Disorders and Trauma Related Symptoms. The validity of the interview was tested by comparing the ratings on the interview subscales with the scores on the Dissociation questionnaires and the Somatoform Dissociation Questionnaire. Participants with eating disorders reported a higher extent of both psychoform and somatoform dissociation compared with the non-clinical individuals. Analyses also showed a correlation between degree of dissociation and severity of eating disorder symptoms. No differences in dissociation were found between the ED subgroups. Participants reporting more dissociation got higher ratings on the interview, indicating convergent validity. Eating disorders seem to be associated with presence and severity of dissociative symptoms. The extent of dissociation needs to be assessed for these individuals as treatment may benefit from a focus on such symptoms in order to increase its effect.
