How Virtual Reality Can Help Treat Patients with Eating Disorders

Leer en español ]

Did you know that more than 70 million people around the world suffer from an eating disorder?

1 in 5 women are affected by an eating disorder. To help lower this number we want to help treat patients suffering from an eating disorder with Virtual Reality.

Treat eating disorders with Virtual reality

The eating disorders, also known as Eating Behavior Disorders (EBD), can be treated very effectively with Virtual Reality. It is a tool particularly beneficial in cases of  Bulimia Nerviosa (BN), Anorexia Nerviosa (AN) and Binge Eating Disorder (BED).

Scientific support 

The effectiveness of Virtual Reality is demonstrated by several studies and can be used to treat various factors. It works as an exposure therapy to reduce the desire or impulse towards food and to normalize eating patterns. As well as increase awareness in patients of their distortion of their own body image, confront and correct such distortion, gain a more realistic perception and reduce dissatisfaction with one’s own body.

Furthermore, there are several psychologists and health centers that have already used this environment to work on Eating Behavior Disorders with Psious.

How does the eating disorder scenario work

The first environment that Psious has created is the Dressing Room which helps work through cognitive restructuring for the distortion of ones body image. How do we do it?

Firstly, the therapist configures a human avatar with the real body dimensions of the patient. Next, during the session, they will ask the patient to modle the body dimensions of the avatar according to how he or she perceives himself or herself. The therapist will be able to superimpose both silhouettes and the patient can see the difference (and the distortion)
between the perception of his own body and how it really is. 

Another advantage of using this environment in Virtual Reality is that it can function as exposure therapy to their own body. Patients often feel anxiety when they are asked to be weighed, measure certain parts of their body, expose them in front of the mirror, etc. We can avoid that with Virtual Reality. Furthermore, with the biofeedback sensor you can automatically control the physiological response, there is also the option of asking the patients units of distress (SUDs) experienced throughout the exercise.

Another positive aspect about this tool is that it allows you to configure several variables to customize avatars to the maximum: gender, skin color, height, neck, chest, waist, hips and legs. The therapist can select each part of the body -from very narrow to very width- following the table of equivalences that we show next:

Psious - Eating disorders - Table of equivalences

As for the patient, they can change the body dimensions of the avatar with the plus (+) and minus (-) symbols. In this way, each part of his body (neck, chest, waist, hip and legs) can be adapted to the detail.

Personalize body dimensons - Psious eating disorders

As explained earlier, the Compare avatars option will allow superimposing the avatar generated by the therapist with the one generated by the patient. The difference between the two will allow us to see the degree of distortion of the body image. The therapist will receive detailed information about the percentage of distortion of the patient at a general level which will tell them which part or parts of the body presents a greater distortion. Thus we can see the general level of distortion and also see the areas that present a greater "patient deviation".

It should be noted that in Psious we have Instructions Manuals for each virtual environment available to our customers. There you can see in detail an explanation of each scenario, a treatment protocol with guides, steps to follow in each session, recommendations for use and recommended bibliography. In addition to videos, courses and case studies. Obviously, it is an information of an advisory nature that the health professional can evaluate and intervene according to the needs and characteristics of each user.

Have you already used Psious to treat EBD? As always, you can leave us your opinions on our social media sites. We love to listen your experiences!
