Summary

The investigators will study the prevalence of dissociative identity disorder (DID) in three populations at risk in cases of childhood psychotrauma : patients with a diagnosis of borderline personality, patients with a diagnosis of functional dissociative crises (FDC) and patients with early psychosis.

The investigators will also study the prevalence of other dissociative disorders and the frequency of complex post-traumatic stress disorder.

The investigators will also look for correlations between the type of maltreatment in childhood, the age of onset of trauma and the type of diagnosis of dissociative disorders.

The investigators hope to include 150 borderline patients, 150 FDC patients and 50 early psychosis patients.

Data collection will be done via a psychometric administration of 7 self-completion questionnaires as well as the completion of the SCID-D semi-structured interview.
