A Multimodal Outcome Study of Eating Disorders

Summary

This research project aims to explore the effectiveness of combined go/no-go training and implementation intentions in targeting binge eating frequency among people with binge eating disorder and bulimia nervosa.

The full intervention is 4 weeks long and consists of completing the training and food diaries every day and meeting with the researcher twice for EEG recording. Moreover, it involves completing questionnaires at baseline, at intervention completion, and one month after the intervention.

Moreover, healthy control participants will be recruitment to complete baseline questionnaires and take part in one EEG recording session in order to assess baseline differences in brain activation in response to computer tasks.

Interventions

BEHAVIORAL

Food specific Inhibitory control training

It involves a go/no-go task in which participants are requested to respond by clicking a particular button when a specific stimulus appears and requested to withhold their response when another particular stimulus appears. Stimuli in this intervention include photos of food and non-food.

BEHAVIORAL

Implementation intentions

It involves designing "if-then" strategies of behaviour. Participants will be asked to describe situations in which they feel they are more prone to behave in a way that is not congruent to their long term goals, and then to plan strategies to behave differently when faced with this situation in the future.

BEHAVIORAL

General inhibitory control training

It involves a go/no-go task in which participants are requested to respond by clicking a particular button when a specific stimulus appears and requested to withhold their response when another particular stimulus appears. Stimuli in this intervention include only non-food pictures.
