Association of childhood neglect with adult dissociation in schizophrenic inpatients.

Background: Dissociation is often related to previous trauma and also occurs frequently in schizophrenia. Dissociation and psychosis may reflect a posttraumatic syndrome in some patients with schizophrenia.

Sampling And Methods: In total, 80 patients diagnosed with schizophrenia were investigated by means of the Childhood Trauma Questionnaire (CTQ), the Dissociative Experience Scale and the Symptom Check List 90-R. CTQ subscales and groups reporting high and low dissociation were compared using MANOVA.

Results: Childhood traumatic experiences were frequent [mean CTQ total score=45.4+/-17.5 (SD)]. Physical neglect was clearly associated with high dissociation, whereas abuse was not. Furthermore, there was a significant association of physical neglect with psychopathological distress not fully accounted for by dissociation.

Conclusions: Dissociation may be specifically linked to childhood physical neglect in patients diagnosed with schizophrenia. Dissociation alone may not explain the effects of childhood maltreatment on adult psychopathology in schizophrenia; however, conclusions from the present study are limited due to its cross-sectional design.
