Official Title: Tratamiento de la Bulimia Nerviosa Mediante exposición a señales Con Realidad Virtual
Brief Summary:
Introduction: The purpose of this research is to develop a new component for cognitive-behavioral treatment (CBT), empirically validated, for binge eating behavior in patients with bulimia nervosa (BN) and binge eating disorder (BED), by means of cue-exposure therapy (CET) with virtual reality. While CBT is an effective treatment for these eating disorders, an important percentage of patients do not improve despite treatment. It is necessary to explore how to enhance the effectivity of usual treatments with the incorporation of new technologies and procedures. The innovation of this investigation is based on the use of VR for cue-exposure therapy, which has been found effective with patients resistant to conventional treatments (CBT and pharmacological intervention), and seeks to enhance this efficacy by increasing possibilities of generalization and providing more useful tools to clinicians, diminishing the logistic complications of the exposure to real cues (food).
Participants: 60 patients with a diagnosis of BN or BED according the DSM-5 who had been proposed for participation in the study by their referral mental health's professional after conducting unsuccessfully a first level treatment (CBT structured intervention) at the clinical sites involved will participate in the study.
Procedure: Participants with active episodes of binge eating (and purging, in the case of BN) during the last 2 weeks of the structured intervention of CBT will be provided with detailed information about the study. All patients who agree to participate in the study and who sign the informed consent form will be randomly assigned to one of the two second-level treatment conditions: virtual reality based cue-exposure therapy (VR-CET) or additional cognitive-behavioral treatment (A-CBT). Both second-level treatment conditions consist of six 60-
