    Abstract:
    The purpose of this research was to study traumatic and dissociative experiences in a sample of Spanish psychotic patients. A total of 37 psychotic patients filled out the Dissociative Experiences Scale (E. B. Carlson & F. W. Putnam, 1993), a questionnaire on traumas (J. R. E. Davidson, D. Hughes, & D. G. Blazer, 1990), and the Positive and Negative Syndrome Scale delusion and hallucinations items (S. R. Kay, L. A. Opler, & J. P. Lindenmayer, 1988). The results showed that 40.5% of the subjects in the sample had undergone at least 1 traumatic experience as children and 64.9% had as adults. Patients with hallucinations had experienced a higher mean number of childhood traumatic experiences than patients without hallucinations. No significant difference in the mean number of traumatic events was found between patients with and without delusions. There was no significant difference in the mean number of adulthood traumatic events between patients with and without hallucinations and delusions. Subjects with childhood traumas scored higher on the Dissociative Experiences Scale than those who had had such experiences as adults. Patients with hallucinations and delusions also scored higher on the dissociation scale than patients who did not show those positive psychotic symptoms.
