What this trial studies

This interventional program delivers dissociation-focused cognitive behavioral therapy (DF-CBT) to adults diagnosed with dissociative disorders at several French university hospitals. Participants who meet eligibility criteria receive structured psychotherapy sessions and must have stable psychiatric medication if applicable. The protocol excludes people with active substance use disorder, certain severe psychiatric diagnoses, current psychotherapy, cognitive deficits, or benzodiazepine treatment. Previous exploratory, uncontrolled work has suggested DF-CBT may be promising, but controlled evidence is still needed.

Who should consider this trial

Good fit: Adults (18+) with a diagnosed dissociative disorder who can attend psychotherapy and provide informed consent are ideal candidates.

Not a fit: People with current substance use disorder (except tobacco), major neurodevelopmental or certain severe psychiatric disorders, cognitive deficits, ongoing psychotherapy, or on benzodiazepines are unlikely to be eligible or benefit from this program.

Why it matters

Potential benefit: If effective, DF-CBT could reduce dissociative symptoms and improve daily functioning for people with dissociative disorders.

How similar studies have performed: Uncontrolled exploratory studies have reported promising results for DF-CBT, but randomized controlled evidence is lacking.
