OBJECTIVE: This study sought to examine the stability of dissociative symptoms in patients with schizophrenia spectrum disorders as well as relationships between psychotic symptoms, childhood trauma, and dissociation. METHOD: One hundred forty-five patients with schizophrenia spectrum disorders (72% schizophrenia, 67% men) were examined at admission to inpatient treatment and 3 weeks later using the Positive and Negative Syndrome Scale, the Childhood Trauma Questionnaire, and the Dissociative Experiences Scale. RESULTS: Dissociative symptoms significantly decreased over time (mean, 19.2 vs 14.1; P < .001). The best predictor of dissociative symptoms at admission was the Positive and Negative Syndrome Scale positive subscale (F(inc)(3,64) = 3.66, P = .017), whereas childhood sexual abuse best predicted dissociation when patients were stabilized (F(inc)(10,80) = 2.00, P = .044). CONCLUSION: Dissociative symptoms in patients with schizophrenia spectrum disorders are related to childhood trauma. Dissociation seems to be state dependent in this diagnostic group. Moreover, diagnostic interviews, in addition to the Dissociative Experiences Scale, should be considered to avoid measurement artifacts.
