- Abstract
Introduction: A well-known link exists between childhood trauma and schizophrenia development in adulthood. Dissociation has been shown to mediate between trauma and psychosis in several studies. A recent meta-analysis demonstrated a relevant and significant relationship between childhood trauma and dissociation in schizophrenia spectrum patients. Objectives: Analyse relationship between childhood trauma and dissociative symptoms in schizophrenia Methods: Retrospective study including adult patients diagnosed with schizophrenia spectrum disorders. Childhood trauma was assessed with the Childhood Trauma Questionnaire (CTQ-SF), which includes 28 items measuring history and intensity of 5 types of trauma (physical, emotional and sexual abuse, physical and emotional neglect). Dissociative symptoms were assessed with the Dissociative Experiences Scale (DES-II), which includes 28 items measuring the occurrence and frequency of several dissociative experiences. Results: Forty-five patients (55.5% men, mean age: 41.1) were included. 77.8% had experienced childhood trauma (48.9% emotional abuse, 28.9% physical abuse, 40.0% sexual abuse, 55.6% emotional neglect, 46.7% physical neglect). Dissociation showed significant and moderate correlation with number of traumatic experiences (r=0.559, p=0.000) and intensity of trauma in the event of emotional abuse (r=0.616, p=0.000), sexual abuse (r=0.582, p=0.000), emotional neglect (r=0.489, p=0.001) and physical neglect (r=0.471, p=0.001). Conclusions: Childhood trauma is highly prevalent in schizophrenia spectrum patients and correlated with dissociative symptoms. We argue in favour of systematic inquiry of childhood traumatic history and dissociative symptoms in such patients.
