• Insight in treatment process provided by weekly comparison of participating groups. • Specific treatment effect by cue exposure and self-control on binge-eating disorder. • Strong effect of the IMPULS program on the reduction of binge-eating episodes. • IMPULS program identified as very helpful with high participant satisfaction. • Reduction of other impulsive behaviors across groups due to weekly self-observations. Impulsivity represents a risk factor for patients with binge-eating disorder, and we therefore investigated the treatment process of impulsive behaviors including binge-eating episodes in the randomized controlled IMPULS trial. Using 8 weekly online questionnaires throughout the assessment period, we compared 41 patients participating in the IMPULS program, which emphasized impulsive eating behavior (IG), with 39 control patients who received no intervention (CG). We assessed the frequency of binge eating, other impulsive behaviors, situations in which such behaviors could be inhibited, and the execution of alternative behaviors. Results indicate a stronger binge-eating reduction in the IG compared to the CG at the fifth, seventh, and eighth treatment weeks. Overall, both groups reduced other impulsive behaviors. They did not differ in the amount of inhibited impulsive behaviors and showed similar alternative behaviors, "distraction" most frequently used. IG patients evaluated the IMPULS program as very helpful. The stronger reduction of binge eating in the IG and positive evaluation of the treatment indicate a specific treatment effect regarding impulsive eating behavior. The reduction of other impulsive behaviors across both groups, and the initial reduction of binge eating within the CG, could be explained by an increased degree of self-observation.
