A study testing Experimental group 1 : Virtual Reality and Experimental group 2 : Virtual Reality + Multi Sensorial Remediation in people with Anorexia Nervosa and Dysmorphophobia, run by Lille Catholic University.
Trial summary
Body distortions are responsible for anorexic behavior reinforcing loops. It is necessary to target this behavior and develop appropriate therapies taking into account the perceptual (implicit) and conceptual (explicit) phenomenon of body representations. Read more about this study

- Child, Adult
Who may be able to join
- Female
- Age ≥ 15 to ≤ 26 years old
- Anorexic nervosa eating disorder according to the criteria of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5). As patients are hospitalized for anorexic nervosa, the medical diagnosis of each care center participating in the inclusions will be trusted
- Patient hospitalized (full hospitalization or day hospital) in one of the investigative centers for a minimum period of 6 weeks
- 14 ≤ BMI ≤ 18.5 for adult patients. For minors, Cole's curves will be used. The Body mass index (BM)I should be between the 1st percentile and the 10th percentile (if the weight curve shows a clear break indicating abnormal weight loss).

About this study
Official title: Virtual Reality Place in the Management of Body Dysmorphia Disorders in Anorexia Nervosa : Comparison of the Recommended Management and Virtual Reality Care Programs With or Without Multisensory Remedy
Body distortions are responsible for anorexic behavior reinforcing loops. It is necessary to target this behavior and develop appropriate therapies taking into account the perceptual (implicit) and conceptual (explicit) phenomenon of body representations.
The main originality of the proposed program consists on combining virtual visual impulses and multisensory recalibration (touch, proprioception, vestibular sensations) in order to compare the body distortions evolution in anorexic patients with or without a multimodal care program including Virtual Reality from its own body scan, coupled or not to a multisensory remediation.
Read the detailed description
Rapid weight loss associated with mental anorexia leads to dysmorphophobia and body distortions. Patients perceive themselves to be bigger than they really are. Body distortions are responsible for anorexic behavior reinforcing loops. It is then necessary to target this behavior and develop appropriate therapies taking into account the perceptual (implicit) and conceptual (explicit) phenomenon of body representations.
The current treatment programs which are recommended by the Haute Autorité de Santé (HAS) in France focus on the somatic, nutritional, individual and family psychological aspects. These recommendations hardly mention the bodily distortion phenomenon which frequently leads patients to relapse into the disease.
The 3D body scanner enables to get awareness of the body through visual feedback allowing the patient to get a reassuring overview of her weight development.
This projects aims to combine virtual visual impulses and multisensory recalibration (touch, proprioception, vestibular sensations) in order to compare the body distortions evolution in anorexic patients with or without a multimodal care program including Virtual Reality from its own body scan coupled or not to a multisensory remediation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Experimental group 1 : Virtual RealityOther
Patients benefit from the care recommended by the HAS, the virtual reality program and time for relaxation and body scan.
Experimental group 2 : Virtual Reality + Multi Sensorial RemediationOther
Patients benefit from the care recommended by the HAS, the virtual reality program, the multisensory remediation, and also the body scan.
| Study group | Role | What they receive |
|---|---|---|
| Control group | No intervention | The patients benefit from the care recommended by the HAS. They benefit from psychological interviews, psychiatric follow-up, dietetic follow-up, family interviews and therapy. Body therapies (physiotherapy, massage, fascia therapy, psychomotor skills, dance therapy, etc.) may also take place. Patients will also benefit from relaxation and body scan. |

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Body Dimensions Estimation task
Body overestimation bias will be assessed by the Body Dimensions Estimation task.
Measured: 6 weeks
Secondary outcomes (6)
Change in Body Shape Questionnaire
The womens body image concerns will be evaluated by the Body Shape Questionnaire. This 34-items questionnaire is scored from 1 (= never) to 6 (= always) to obtain a global score.
Measured: 6 weeks
Change in Physical self description questionnaire
The Physical self description will be measured by the Physical Self Description Questionnaire (PSQD). This questionnaire estimates 11 sub-dimensions of the physical self from 70 items on a continuum ranging from 1 (very negative perception) to 6 (very positive perception).
Measured: 6 weeks
Change in Body Image Questionnaire
Patients bodily satisfaction will be assessed by the Body Image Questionnaire. This questionnaire consists of 19 items scored on 5 points. It gives a total body satisfaction score between 19 and 95 and 4 scores relative to 4 different factors (accessibility/closure, satisfaction/dissatisfaction, active/passive, serenity/tension).
Measured: 6 weeks
Change in Weight gain
Weight gain will be measured by weighting.
Measured: 6 weeks
Change in Eating Disorder Examination Questionnaire
Eating disorders will be assessed by the Eating Disorder Examination Questionnaire (EDE-Q). This questionnaire is divided into several sub-scores: restriction, dietary concerns, body shape concerns and weight concerns. It has 30 items scored from 0 (= no day) to 6 (= every day). A score for each subscale and an overall score can be obtained.
Measured: 6 weeks
Anxiety measured by the State-Trait Anxiety Inventory (STAI-Etat-Trait)
Anxiety will be measured by the STAI-Etat-Trait . Each of the dimensions (STAI-state and Stai-trait) are measured by 20 items scored from 1 (= no or never) to 4 (= yes or almost always) which is summarized by a score.
Measured: 6 weeks
