PrevED MR. Improving Emotion Dysregulation Through Mixed Reality Based Dialectical Behavioral Therapy in Adolescents and Young Adults at Risk of Developing Eating Disorders. (PrevED MR)
The aim of this study is to evaluate the feasibility and preliminary effects of PrevED MR, a group-based preventive intervention for adolescents and young adults at risk of developing eating disorders. PrevED MR is based on dialectical behavior therapy skills and uses mixed reality and virtual reality activities to support emotion regulation, mindfulness, distress tolerance, and body-related acceptance.
Participants will be randomly assigned to either the PrevED MR intervention group or a waiting-list control group. The intervention will be delivered over 6 weeks, with two sessions per week, for a total of 12 sessions. Assessments will be conducted at baseline and after the intervention to examine changes in eating disorder symptoms, body image acceptance, emotion regulation strategies, rumination, usability, sense of presence, cybersickness, satisfaction, and adherence.

Description détaillée
Eating disorders are serious mental health conditions that often emerge during adolescence and young adulthood. Difficulties in emotion regulation, including rumination, emotional suppression, low emotional acceptance, and limited cognitive flexibility, are relevant processes associated with eating disorder risk and symptom maintenance. Preventive interventions that target emotion regulation skills may help reduce eating disorder risk in young people.
PrevED MR is a mixed reality- and virtual reality-supported preventive intervention designed for adolescents and young adults at risk of developing eating disorders. The intervention is grounded in dialectical behavior therapy skills training and combines psychoeducation, paper-based exercises, group activities, and guided immersive experiences. The program focuses on core skills related to mindfulness, emotion identification, emotion regulation, distress tolerance, acceptance, and non-judgmental body-related exposure.
This study is a pilot randomized controlled trial with two parallel arms: an experimental intervention group and a waiting-list control group. Participants allocated to the experimental group will receive the PrevED MR intervention over 6 weeks, with two sessions per week, for a total of 12 sessions. Sessions will be delivered face-to-face in small groups and supervised by trained mental health professionals. Participants allocated to the waiting-list control group will continue their usual activities during the initial study period and will not receive the intervention before the post-intervention assessment.
The study will recruit Spanish-speaking adolescents and young adults who are at mid-to-high risk of developing eating disorders. Participants will complete baseline and post-intervention assessments. Primary outcomes will focus on eating disorder symptoms and body image acceptance. Secondary outcomes will include emotion regulation strategies, rumination, usability, sense of presence, cybersickness, satisfaction, and adherence. The study will also examine whether intervention effects differ according to age group and gender.

Expérimental: PrevED MR Intervention
Participants assigned to this arm will receive the PrevED MR intervention, a 6-week group-based preventive program for adolescents and young adults at risk of developing eating disorders.
The intervention includes 12 face-to-face group sessions delivered twice weekly and combines psychoeducation, paper-based exercises, group activities, and guided mixed/virtual reality experiences based on dialectical behavior therapy skills.

Aucune intervention: Waiting-List Control
Participants assigned to this arm will continue their usual activities during the 6-week study period and will not receive the PrevED MR intervention before the post-intervention assessment.
They may be offered access to the intervention after completion of the post-intervention assessment.

Change in Eating Disorder Symptoms
Délai: Baseline and post-intervention, approximately 6 weeks after baseline
|
Eating disorder symptoms will be assessed using the Eating Attitudes Test-26 and selected subscales of the Eating Disorder Inventory-3.
The Eating Attitudes Test-26 total score includes 26 items scored from 0 to 3, with a total score ranging from 0 to 78; higher scores indicate greater eating disorder symptomatology.
The Eating Disorder Inventory-3 Drive for Thinness subscale includes 7 items scored from 0 to 5, with a total score ranging from 0 to 35; higher scores indicate a stronger drive for thinness.
The Eating Disorder Inventory-3 Body Dissatisfaction subscale includes 10 items scored from 0 to 5, with a total score ranging from 0 to 50; higher scores indicate greater body dissatisfaction.
A reduction in scores from baseline to post-intervention indicates improvement.

Baseline and post-intervention, approximately 6 weeks after baseline

Change in Body Image Acceptance
Délai: Baseline and post-intervention, approximately 6 weeks after baseline
|
Body image acceptance and body image-related psychological flexibility will be assessed using the Body Image Acceptance and Action Questionnaire.
The questionnaire includes 12 items scored from 1 to 7, with a total score ranging from 12 to 84.
Higher scores indicate greater body image-related psychological inflexibility and lower body image acceptance.
Therefore, a reduction in scores from baseline to post-intervention indicates improvement.

Change in Emotion Regulation Strategies
Délai: Baseline and post-intervention, approximately 6 weeks after baseline
|
Emotion regulation strategies will be assessed using the Emotion Regulation Questionnaire.
The questionnaire includes 10 items scored from 1 to 7, with higher item scores indicating greater agreement with each statement.
The Cognitive Reappraisal subscale includes 6 items and ranges from 6 to 42; higher scores indicate greater use of cognitive reappraisal.
The Expressive Suppression subscale includes 4 items and ranges from 4 to 28; higher scores indicate greater use of expressive suppression.
Higher cognitive reappraisal scores are generally interpreted as a more adaptive emotion regulation strategy, whereas higher expressive suppression scores are generally interpreted as a less adaptive emotion regulation strategy.

Baseline and post-intervention, approximately 6 weeks after baseline
|
|
Change in Rumination and Worry
Délai: Baseline and post-intervention, approximately 6 weeks after baseline
|
Rumination and worry-related repetitive negative thinking will be assessed using the Penn State Worry Questionnaire.
The questionnaire includes 16 items assessing the tendency to worry, using response options ranging from 1 to 5. The total score ranges from 16 to 80, with higher scores indicating higher levels of worry and repetitive negative thinking.
Therefore, a reduction in scores from baseline to post-intervention indicates improvement.

System Usability
Délai: Post-intervention, approximately 6 weeks after baseline
|
The System Usability Scale (SUS) is a widely used 10-item self-report questionnaire designed to assess perceived usability of a system, product, or technology.
Items are rated on a 5-point Likert scale from 1 (Strongly Disagree) to 5 (Strongly Agree), with scores converted to a 0-100 scale.
Higher scores indicate better perceived usability.

Cybersickness Symptoms
Délai: Baseline and post-intervention, approximately 6 weeks after baseline
|
The Simulator Sickness Questionnaire (SSQ) is a self-report instrument designed to assess symptoms of motion sickness or discomfort experienced during or after virtual reality exposure.
The SSQ consists of 16 items grouped into three subscales: Nausea, Oculomotor, and Disorientation.
Participants rate the severity of each symptom on a 4-point Likert scale: 0 (None), 1 (Slight), 2 (Moderate), 3 (Severe).
Total and subscale scores are calculated according to standardized formulas, with higher scores indicating greater severity of simulator-induced discomfort.
