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 Intervention: PrevED MR is a 6-week group-based preventive intervention for adolescents and young adults at risk of developing eating disorders. The program includes 12 face-to-face group sessions delivered twice weekly and combines psychoeducation, paper-based exercises, group activities, and guided mixed/virtual reality experiences. The intervention is based on dialectical behavior therapy skills and targets mindfulness, emotion identification, emotion regulation, distress tolerance, acceptance, and non-judgmental body-related exposure.
Study summary
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.

Primary outcome measure(s)
Change in Eating Disorder Symptoms — 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.
Change in Body Image Acceptance — 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.
