The aim of this article was to study the effect of virtual-reality exposure to situations that are emotionally significant for patients with eating disorders (ED) on the stability of body-image distortion and body-image dissatisfaction. A total of 85 ED patients and 108 non-ED students were randomly exposed to four experimental virtual environments: a kitchen with low-calorie food, a kitchen with high-calorie food, a restaurant with lowcalorie food, and a restaurant with high-calorie food. In the interval between the presentation of each situation, body-image distortion and body-image dissatisfaction were assessed. Several 2Â2Â2 repeated measures analyses of variance (high-calorie vs. low-calorie foodÂpresence vs. absence of peopleÂED group vs. control group) showed that ED participants had significantly higher levels of body-image distortion and body dissatisfaction after eating high-calorie food than after eating low-calorie food, while control participants reported a similar body image in all situations. The results suggest that body-image distortion and body-image dissatisfaction show both trait and state features. On the one hand, ED patients show a general predisposition to overestimate their body size and to feel more dissatisfied with their body image than controls. On the other hand, these body-image disturbances fluctuate when participants are exposed to virtual situations that are emotionally relevant for them.

“…Finally, it should be mentioned that future VR environment developments should make acquisition and use of 3D simulation systems in clinical practice less expensive. In this sense, several studies have shown that it is unnecessary to use costly 3D simulation systems (Krijn et al, 2004;Letosa-Porta et al, 2005;Carmona et al, in press). One of the great challenges for the future of VR environment development is therefore creation of effective 3D simulation programs which were more economical and easy to use, and thus more affordable to more www.intechopen.com…”

“…These results definitely show the ability of VR to provoke the characteristic responses present in people with binge eating disorders (Perpiñá et al, 2003). In another study to evaluate the type of responses triggered by VR environments in this type of problem, Letosa-Porta et al (2005) developed a tool for perfecting some of the technical limitations of previous studies called Body Image Assessment Software (BIAS). BIAS provided greater freedom in modeling body proportions of the virtual person (avatar) to make it as similar as possible to the participant's measurements, and at the same time it allowed modification of specific body parts while maintaining a holistic vision of the avatar.…”

“…To ensure that the image is not polygonal (and thus unrealistic), a module smooths the reference measurements and gives the image a more natural appearance. All these specifications can be found in Letosa-Porta et al (2005).…”

The aim of the present study was to analyze the psychometric characteristics of the Body Image Assessment Software (BIAS), an innovative interactive computer program developed to assess body image disturbances. The program was tested on 252 psychology students at the University of Barcelona and 51 patients with an eating disorder (ED). The subjects filled in the Eating Attitudes Test-26, the Body Shape Questionnaire, the body dissatisfaction scale of the Eating Disorders Inventory-2, and the Body Image Assessment-Revised (a test of silhouettes). Results showed good validity and very high reliability. Furthermore, BIAS was able to discriminate between people who were at risk of an ED and those who were not, as well as between people with and without a history of an ED. Those at risk of having an ED and those with a current ED showed more body image distortion (overestimation of body size) and higher levels of body image dissatisfaction.
