Eligibility

Age

Design outcomes

Primary

Measure	Time frame
The main study parameters to assess whether there are differences in the attentional processing of food stimuli, food cue-elicited craving and eating behavior in women with and without food binges are: - Visual dot probe task: average reaction time to a probe when this probe appears at the position of a food picture (congruent trials), relative to the average reaction time to the probe when the probe appears at the position of a neutral picture (incongruent trials). The difference score is the congruency effect (index of attentional bias). - Eye-tracking: total fixation time, total fixation frequency and average glance duration towards pictures of food (relative to neutral pictures) - Event-related potentials (counting task): amplitude of the P3 and LPP components (indices of motivated attention) elicited by pictures of food (relative to non-food-related pictures). - Self-report questionnaire scores with regard to (pretest + posttest) food craving and hunger - Food diary: pretest and posttest energy intake	—

Secondary

Measure	Time frame
Other parameters of interest / possible confounders are: - Scores on self-report questionnaires with regard to eating behavior and eating disorder symptoms, affect and depressive symptoms; - Valence and arousal ratings of the used pictorial stimuli - Body Mass Index [body weight (kg)/length (m)²] - Age - Educational level	—
