In the treatment of eating disorders, the cognitive behavioral therapy (CBT) is still considered the best approach but could present different limitations related to costs of behavioural procedures (such as exposure and desensitization) or difficulty of cognitive techniques (such as imagination of daily scenarios). The major aim of this contribution is the description of a new Virtual Reality-enhanced treatment named Experiential Cognitive Therapy (ECT). Rationale and protocols about this new approach are explained. Moreover data about clinical trials, carried on with the VEPSY Project, are shown comparing different groups: experimental group (ECT), cognitive-behavioural therapy group (CBT), nutritional group and control group.
