Brief summary in scientific language

Binge Eating Disorder (BED) is characterised by recurring episodes of binge eating with a perceived loss of control. Exprimental studies hint that general as well as food-related impulsivity represent a risk factor for BED (cf. Schag, Schönleber et al., 2013; Schag, Teufel et al., 2013). Accordingly, we propose that a behavioral intervention specifically focusing on impulsivity is able to increase the control about impulsive eating behaviour and thus, reduce binge eating episodes, impulsivity and weight in the longterm. In this project, we investigate the efficacy of a manualised impulsivity-focused behavioural modification programme for patients with BED in a randomised controlled trial.

Interventions, Observational Groups

Arm 1:
experimental group: patients with Binge Eating Disorder participating on the impulsivitry-focused behavioural modification programme. This is a group intervention with 8 weekly sessions á 90 minutes, i.e. the duration of the intervention is 8 weeks.
Arm 2:
control group: patients with Binge Eating Disorder who do not participate on the impulsivitry-focused behavioural modification programme.

Endpoints

Primary outcome:
The frequency of binge eating episodes within the last 4 weeks at T0 (at the beginning) and T1 (after 8 weeks (at the end of the training period)), assessed by Item 10 of the Eating Disorder Examaniation Interview (Hilbert & Tuschen-Caffier, 2004)
Secondary outcome:
Changes between T0 and T1 as well as T1 and T2 (3 months after end of the training period) concerning a) impulsivity: eyetracking variables assessing fodd-related and general impulsivity in the free exploration and antisaccade paradigms, BIS-15 and BIS/BAS questionnaires, b) psychopathology und impulsive eating behaviour by EDE, EDE-Q, BDI II, BMI (kg/m2), DEBQ, YFAS, FCQ-S and FCQ-T, c) Ratings of the valence of the used stimuli in the eye tracking paradigms. Further, we analyse process questionnaires concerning binge eating episodes and impulsive behaviour, weekly assessed between T0 and T1, i.e. eight times and an evaluation questionnaire concerning the impulsivity-focused behavioral modification programme.
