Evaluation of the Efficacy of Dissociation-Focused Cognitive Behavior Therapy

Dissociative symptoms and disorders are particularly prevalent in the general population and among people suffering from psychiatric disorders. To date, no treatment has proven effective for this type of problem. Exploratory studies (without control group) have been carried out.
