정신분열병의 해리증상, 아동기 학대 및 임상증상의 관계

Abstract

Objectives：Studies consistently find high prevalence of early sexual or physical abuse among the schizophrenic population suggesting a possible linkage between psychological trauma and schizophrenia. This study sought for clin¬ical correlates of dissociative symptoms in schizophrenia concerning childhood abuse and a variety of symptoms. Methods：Sixty-one inpatients with schizophrenia completed Dissociative Experiences Scale(DES), Symptom Checklist-90-Revised(SCL-90-R), Positive and Negative Syndrome Scale(PANSS), and a semistructured inter¬view on abuse history. Results：The Global Severity Index(GSI) of SCL-90-R, positive symptom, chlorpromazine equivalent, and child ¬hood abuse were significantly correlated with DES scores. However, multiple regression analysis yielded GSI and positive symptom accounting 57% of variance for DES scores. Conclusion：This finding suggests that the symptoms of dissociation in schizophrenia are rather associated with severity of general symptomatology and positive symptoms than history of childhood abuse. Some portion of schiz¬ophrenic population with high scores on DES need to be further investigated for their characteristics and patho¬physiology.
