Resum
This article reviews the 6-month followup data of a randomized, multicenter, parallel-group study conducted at five clinical sites in three European cities, which compared two second-level treatments for bulimia nervosa (BN) and binge eating disorder (BED): virtual reality-based cue exposure therapy (VR-CET) versus additional cognitive behavioral therapy (A-CBT). Post-treatment outcomes of this study were already published in Ferrer- Garcia et al. (2017) and details of its design can be found at clinicaltrials.gov (identifier: NCT02237300, https:// clinicaltrials.gov). This article focuses on the evolution of symptoms assessed after 6 months of followup in a subgroup of 58 patients from the original study. In this study (Ferrer-Garcia et al., 2017) 64 patients with eating disorders (EDs) (35 with BN and 29 with BED), who still showed active episodes of binge eating by the end of a structured CBT program (first-level treatment), were randomly assigned to one of two second-level treatments (A-CBT or VR-CET). Frequency of binge and purge episodes, and attitudinal features of binge-related EDs (bulimia, drive for thinness, and body dissatisfaction) were assessed before starting the second-level treatment (n = 64), at the end (n = 64), and at 6-month followup (n = 58). Mixed between-within subject analyses of variance were used to compare outcomes of both second-level treatments over time. Although both treatment conditions showed statistically significant improvements at the end and after 6-month followup, obtained reductions were greater after VR-CET, regarding binge and purge episodes, as well as the decrease of selfreported tendency to engage in overeating episodes. Accordingly, abstinence from binge episodes were higher in VR-CET than A-CBT at followup (70 percent vs. 26 percent, respectively; v2 = 11.711, p = 0.001). These results provide further support for the use of VR-CET as an effective second-level intervention for BN and BED treatment-resistant patients.
