Childhood emotional abuse and dissociation in patients with conversion symptoms.
The aim of the present study was to evaluate the relationship between reported childhood trauma and dissociation in patients who have a conversion symptom. Thirty-two outpatients with a conversion symptom were evaluated using Dissociative Experiences Scale, Somatoform Dissociation Questionnaire, Childhood Trauma Questionnaire, Spielberger Trait Anxiety Inventory, Clinician-Administered Dissociative State Scale, and Dissociative Disorders Interview Schedule. A DSM-IV dissociative disorder was diagnosed in 46.9% of the patients. Conversion patients with a dissociative disorder had borderline personality disorder more frequently than those without a dissociative disorder. Among childhood trauma types, emotional abuse was the only significant predictor of dissociation in regression analysis. None of the childhood trauma types predicted borderline personality disorder criteria. Borderline personality disorder, dissociation and reports of childhood emotional abuse refer to a subgroup among patients with conversion symptom. Dissociation seems to be a mediator between childhood trauma and borderline phenomena among these patients.
