Anorexia Nervosa Clinical Trial
Official title:
Evaluating the Efficacy of Radically Open Dialectical Behaviour Therapy (RO-DBT) in Patients With Anorexia Nervosa: a Randomized Controlled Clinical Trial
Randomized controlled clinical trial to evaluate the efficacy of "Radically Open Dialectical Behaviour Therapy" in patients with eating disorders: a proof-of-concept study.
Background: Up to 20% of patients with anorexia nervosa (AN) die and 50% relapse after the first episode, being its treatment a great challenge for clinicians. Most therapies excessively focus excessively on nourishment, which translates to temporarily restored weight with no improvements in psychosocial life. Radically Open Dialectical Behaviour Therapy (RO-DBT) is a transdiagnostic treatment designed to treat overcontrol, a key aspect in the functioning of patients with AN. To date no clinical trial (CT) has proved its efficacy on these patients or has demonstrated its biological underpinning mechanisms. Methods: A randomized CT in AN patients will be conducted, where one group will receive treatment as usual (TAU) and the other one TAU with plus RO-DBT, being psychosocial adjustment the main outcome; other secondary variables will be ED symptoms, overcontrol characteristics, autistic traits and neuroimaging changes. Discussion: The results will fill the a knowledge gap in AN treatment, expecting that patients who receive TAU with RO-DBT will have better social adjustment and less relapses at one year follow up. This is the first study examining neuroimaging changes in RO-DBT to better understand its underlying mechanisms ;
