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. Among these studies, dissociation-focused cognitive behavioral therapy (DF-CBT) seems promising. DF-CBT is based on a solid empirical model that has received numerous scientific evidence.
41 studies on the registry are indexed under Dissociative Disorders; 13 are open to participants now.
