Design outcomes

Primary

Measure	Time frame
1) Difference between people with BED, overweight people without BED and normalweight people without BED, regarding attentional processes concerning food stimuli (hypothesis formulated for BED-group in comparison to control groups): a) Eyetracking: First fixation more frequently on food stimuli b) ET: First fixation longer, when on food stimuli c) ET: Longer gaze duration on food stimuli in general d) ET: Stronger bias on food stimuli corresponds with more severe eating disorder symptoms e) EEG: Shorter latencies and higher amplitudes in the ERPs on food stimuli. f) Higher amplitudes on food stimuli correspond with more severe eating disorder symptoms g) Behavioral data: Stonger approach and weaker avoidance tendencies for food stimuli	—

Secondary

Measure	Time frame
2) Does the bias modification training lead to the development of health enhancing attentional patterns on food stimuli? a) In the bias modification group but not in the control training group there is a significant reduction of the eating disorder symptoms b) In the bias modification group but not in the control training group there is a reduction of dysfunctional attentional patterns on food stimuli (pre/post comparison for the measurements in 1) )	—
