Radically Open Dialectical Behaviour Therapy in Patients With Anorexia Nervosa (RODBT-AN)

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.

Study Overview

Detailed Description

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

Arms and Interventions

Intervention / Treatment
Other: Treatment as Usual (TAU)
The TAU condition will follow the standard treatment of the EDs Unit of the HSCSP for AN. This treatment consists of visits with a psychiatrist with a frequency decided according to the clinical situation and, in some cases, nursing follow-up and/or relapse prevention group that takes place twice per month

Experimental: TAU + Radically Open Dialectical Behaviour Therapy (RO-DBT)
2. TAU + skills of the RO-DBT: In this treatment branch, a RO-DBT skills training therapy will be added to TAU. Treatment and therapists: RO DBT skills training consists of a 30-week intervention program in which a set of skills specifically designed to treat overcontrol are taught on an ongoing basis. The duration of each session is 2 hours. Table X provides an overall summary of each skill training session content. Detailed and extensive information about the treatment can be found elsewhere [24], [34]. Three clinical psychologists and one psychiatrist will conduct the treatment, all of whom have undergone extensive training in RO DBT. A maximum of two therapists will be in charge of each session, and the same two therapists will go throughout each group intervention. The team will be supervised by an approved RO DBT supervisor to improve therapeutic skills and ensure adherence to the protocol.
RO-DBT is a transdiagnostic intervention specifically designed to treat a spectrum of disorders characterized by excessive overcontrol such as resistant depression, avoidant and obsessive-compulsive personality disorders, mood disorders, anorexia nervosa and autism spectrum disorder.
