What this trial studies
This study investigates the prevalence of dissociative identity disorder (DID) among three at-risk outpatient groups: individuals with borderline personality disorder, those experiencing functional dissociative crises, and patients with early psychosis. The research aims to assess the prevalence of other dissociative disorders and complex post-traumatic stress disorder (PTSD) while exploring correlations between childhood maltreatment, trauma onset age, and dissociative disorder diagnoses. Data will be collected through psychometric assessments and semi-structured clinical interviews, involving a total of 350 participants across the specified groups.
Who should consider this trial
Good fit: Ideal candidates include adults aged 18 and older with a history of childhood psychotrauma and specific diagnoses related to dissociative disorders.
Not a fit: Patients without a history of childhood trauma or those not fluent in French may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance understanding and treatment of dissociative disorders in patients with a history of childhood trauma.
How similar studies have performed: While the specific approach may be novel, studies have shown that understanding the prevalence of dissociative disorders in trauma-affected populations can lead to improved diagnostic and therapeutic strategies.
