BACKGROUND Web-based guided self-help cognitive behavioral therapy-enhanced (CBT-E) is a 12-weeks, 12-sessions, digitalized version of part II of the self-help book Overcoming Binge Eating. This intervention is effective when offered under controlled circumstances in a randomized-controlled-trial. It is unknown how patients with binge-eating disorder (BED) respond to this intervention when offered in real-world clinical-settings. The aim of this study is to examine post-intervention effectiveness of guided self-help CBT-E for BED in real-world settings. METHODS The present study used a cohort-design examining the effectiveness of web-based guided self-help CBT-E according to an intention-to-treat (ITT) analysis. BED patients (n = 278) were assessed pre- and post-intervention. The primary outcome was reduction in binge-eating episodes. Other outcomes were full-recovery (EDE-Q score <2.77 and abstinence from binge-eating episodes), impaired psychosocial functioning, defined as secondary impairment, and general psychopathology post-intervention. RESULTS The number of binge-eating episodes reduced by an average of 16 binge-eating episodes per 4 weeks pre-intervention to five binge-eating episodes during the last 4 weeks of treatment. Abstinence from binge eating was reported by 30%, and 28% reported full recovery. Effect sizes (Cohen's d) were large (d ≥ 1.0) for all outcome measures. There were no differences in outcomes between the ITT and the completers sample. CONCLUSIONS Guided self-help CBT-E is associated with significant improvements. The effects of guided self-help CBT-E offered in a real-world-setting are comparable to self-help CBT-E offered in a randomized-controlled-trial. However, it should be noted that comparisons with randomized-controlled-trials requires caution. Longer-term follow-up data are necessary to measure persistence of treatment benefits. Offering CBT-E as a web-based guided self-help intervention has several benefits for patients with BED. Guided self-help CBT-E is associated with significant improvements on the short term when offered in real-world clinical settings.
