Nevertheless, factors associated with successful clinical outcomes of EDBE are still unknown. Our study aimed to test the hypothesis that a history of abuse is associated with unsuccessful clinical outcomes of EDBE through an effect mediated by impulsivity. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> We assessed patients older than 15 years, 3 months with EDBE at inclusion and at 1 year. Recovery was defined as the absence of eating disorders at 1 year. A mediation analysis was performed by means of structural equation modelling. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> We included 186 patients in our analyses (54% bulimia nervosa, 29% anorexia nervosa binge eating\/purging type and 17% binge-eating disorder); 179 (96%) were female. One-third ( n = 63) of patients reported a history of abuse, and recovery was observed for 20% of the sample ( n = 38). Contrary to our assumption, a history of abuse was not associated with the absence of recovery of EDBE at 1 year. Factors unfavourable for achieving recovery were anxiety disorders (odds ratio [OR] 0.41), vomiting (OR 0.39), physical hyperactivity (OR 0.29), negative urgency and a lack of perseverance (OR 0.85 for both). Only positive urgency was positively associated with recovery (OR 1.25). <\/jats:p><\/jats:sec><jats:sec><jats:title>Limitations:<\/jats:title><jats:p> We excluded 219 patients lost to the 1-year follow-up. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> Our findings may help to deconstruct the empirical belief that traumatic events may interfere with the successful course of treatment for eating disorders.
