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.

psychometric assessment
Diagnostic testPsychometric testing to assess trauma and dissociative disorders, and in particular dissociative identity disorder.
semi-structured clinical interview
Diagnostic testSemi-structured interview for the assessment of dissociative disorders (SCID-D : Semi-structured Clinical Interview for diagnosing DSM-5 and ICD-11 Dissociative Disorders)
SCID-D : Semi-structured Clinical Interview for diagnosing DSM-5 and ICD-11 Dissociative Disorders / DSM = Diagnostic and Statistical Manual of Mental Disorders / ICD = International Classification of Diseases
assesses the dissociative identity disorder
SCID-D : Semi-structured Clinical Interview for diagnosing DSM-5 and ICD-11 Dissociative Disorders
assesses the 4 others domains of dissociative disorders
CTQ-28 : Childhood Trauma Questionnaire
assesses history of childhood abuse and childhood trauma. For the CTQ-28, the overall score is not really relevant, but rather the scores for each type of abuse. For each type of maltreatment, there are differences in severity, ranging from "none" to "severe", with threshold scores for each level. In fact, there is no real overall minimum or maximum score.
life events inventory DSM-5
assesses history of potentially traumatic life events. There is no numerical score, it's simply an inventory of potentially traumatic life events.
PCL-5 : Posttraumatic stress disorder CheckList-5
assess the Post Traumatic Stress Disorder. For the PCL-5, the threshold score is 33, so a score of 33 or more suggests the presence of PTSD : the higher the score, the greater the symptomatology. The score is not a value used for interpretation purposes. The investigators use only threshold scores, or diagnostic criteria.
