Emotional Dysregulation, Maladaptive Overcontrol in Anorexia - Effect of Radically Open Dialectical Behaviour Therapy (EMARO)
February 2, 2024 updated by: Umeå University
Emotional Dysregulation and Maladaptive Overcontrol in Anorexia Nervosa and the Effect of Radically Open Dialectical Behaviour Therapy
The goal of this clinical trial is to study the effect of Radically Open Dialectical Behaviour Therapy (RO-DBT) in patients with anorexia nervosa (AN) in an extended baseline experimental case series study design over 30 weeks.
The main questions the trial aims to answer are:
- Does RO-DBT reduce eating disorder psychopathology in AN as measured by the Eating Disorder Examination Questionnaire (EDE-Q)?
- Does RO-DBT reduce maladaptive overcontrol and neuroticism in AN as measured by change in the total score of the Five-Factor Obsessive Compulsive Inventory (FFOCI-SF), and the neuroticism domain in the NEO Five-Factor Inventory-3 (NEOFFI-3), respectively?
- Does RO-DBT reduce emotional dysregulation in AN as measured by change in the Expressive Supression subscore of Emotion Regulation Questionnaire (ERQ)?
- Does RO-DBT increase body weight as measured by change in Body Mass Index (BMI)?

Detailed Description
Anorexia nervosa (AN) demonstrate high chronicity rates and high mortality rates.
The prevalence of AN is relatively high with no effective treatment available and often long treatment durations and high dropout rates.
Emotional dysregulation (EDR), neuroticism and maladaptive overcontrol (MO) are essential in the psychopathology of AN and directly involved in the high mortality and chronicity of the disorder.
Radically Open Dialectical Behaviour Therapy (RO-DBT) addresses MO and has been found effective in pilot studies in AN.
Given this, and the urgent need for effective treatments for AN, this project aims to study the effect of RO-DBT in reducing ED symptoms, MO, neuroticism, and EDR in patients with AN.
This will be done using an extended baseline experimental case series study design over 30 weeks with 31 patients older than 16 years of age with typical or atypical AN.
All outcomes will be assessed using validated psychometric instruments, and RO-DBT will be performed by trained psychotherapists.

Intervention / Treatment |
---|---|
Experimental: Radically Open Dialectical Behaviour Therapy (RO-DBT)
RO-DBT consists of a 1 hour weekly individual session and a 2,5 hour weekly group skill training during 39 weeks in accordance with the published treatment manual and session guides for RO-DBT.
For skills training, the 31 patients will be divided into four equal groups in terms on number.
|
RO-DBT is a transdiagnostic intervention specifically designed to treat a spectrum of disorders characterized by excessive overcontrol such as anorexia nervosa, autism spectrum disorder, refractory depression, cluster c personality disorders, and mood disorders.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Eating Disorder Examination Questionnaire (EDE-Q)
Time Frame: 30 weeks
|
A 36-item self-report questionnaire designed to measure eating disorder symptoms.
The range of scores is 0-132.
Higher scores mean more eating disorder symptoms
|
30 weeks
|
Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
The NEO Personality Five-Factor Inventory-3 (NEO-FFI-3): neuroticism subscale
Time Frame: 30 weeks
|
A 12-item self-report subscale questionnaire designed to measure the personality trait neuroticism.
The range of scores is 12-144.
Higher scores mean higher neuroticism.
|
30 weeks
|
The Five Factor Obsessive Compulsive Inventory - Short Form (FFOCI-SF)
Time Frame: 30 weeks
|
A 48-item self-report questionnaire designed to measure obsessive-compulsive personality traits.
The range of scores is 48-240.
Higher scores mean more obsessive-compulsive personality traits.
|
30 weeks
|
The Emotion Regulation Questionnaire (ERQ)
Time Frame: 30 weeks
|
A 10-item self-report questionnaire designed to measure adaptive and maladaptive strategies for emotion regulation.
The adaptive subscale contains 6 questions and range between 6-42.
Higher scores on this subscale mean more adaptive regulation strategies.
The maladaptive subscale contains 4 questions and range between 4-28.
Higher scores on this subscale mean more maladaptive regulation strategies.
|
30 weeks
|
Body mass index (BMI)
Time Frame: 30 weeks
|
A statistical index using a peron's weight and height to provide an estimate of body fat in people.
A BMI of <18.5 indicates medically underweight.
A BMI of 18.5 - 25 indicates normal weight.
A BMI of >25 indicates overweight.
