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

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. |
Behavioral: Radically Open Dialectical Behaviour Therapy (RO-DBT)
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.

Outcome Measures
Primary Outcome Measures
- Quality of Life Enjoyment and Satisfaction Questionnaire, Q-LES-Q [6 months]
A self report questionarie that assesses quality of life. The range of scores is 0-100. Higher scores mean higher quality of life.
- Quality of Life Enjoyment and Satisfaction Questionnaire, Q-LES-Q [12 months]
A self report questionarie that assesses quality of life. The range of scores is 0-100. Higher scores mean higher quality of life.
Secondary Outcome Measures
- Clinical relapses [6 months, 12 months]
having BMI below 19kg/m2 during two or more weeks, and having a punctuation of the EAT above 21.
- Eating Disorder Inventory, EDI [6 months, 12 monghs]
A self report questionarie that assesses eating disorder symptomatology. The range of scores is 0-192. Higher scores mean higher eating disorders sympthoms
- Autism-Spectrum Quotient, AQ [6 months, 12 months]
A self report questionarie that assesses autistic traits. The range of scores is 0 to 50. Higher scores mean higher autistic traits.
- Rosenberg Self-Esteem Scale, RSE. [6 months, 12 months]
A self report questionarie that assesses self steem. The scale ranges from 0-30. Higher scores mean higher self-esteem. The range scores is 0-60.
- Inventory of Interpersonal Problems (IIP-64) [6 months, 12 months]
A screening measure for avoidant personality disorder (AVPD), and for personality disorder (PD) in general.
- Social Connectedness Scale-Revised, SCS-R [6 months, 12 months]
This scale assesses the degree to which a person feel connected to others in their social environment. Scores range from 20 to 120 higher score indicates more connectedness to others.
- Depression Anxiety and Stress Scale 21 (DASS-21) [6 months, 12 months]
A self-report scale designed to measure the negative emotional states of depression, anxiety and stress.
- Neuroimaging variables [6 months, 12 months]
structural and functional magnetic resonance images will be acquired at baseline and at 1- month follow-up for all the participants, and in one single occasion for the healthy control group.
- Clinical Outcomes in Routine Evaluation-Outcome Measure, CORE-OM, [6 months, 12 months]
A self-report measure of psychological distress designed to be administered during a course of treatment to determine treatment response. The broad spectrum nature of the measure means it captures a wide variety of problems associated with mental health difficulties, beyond typical symptom measures.
- Assessed with the Questionnaire envy in adults, CEA [6 months, 12 months]
This is composed of 24 items representing all theoretical dimensions. Higher scores show higher envy.
