Training App for Inhibitory Control Towards Food

The aim of this project is to test the feasibility, acceptability and clinical impact of a mobile app-based intervention (FoodTraining) to strengthen food-related inhibitory control over 4 weeks, in a sample of people with eating or weight disorders (i.e. obesity, binge-eating disorder (BED), or bulimia nervosa (BN)) receiving standard outpatient treatment (i.e., treatment as usual (TAU) encompassing guided self-help or psychotherapy, pharmacological therapy or diet). The training will be offered in addition to TAU (experimental group) and compared to TAU alone (control group). Participants will complete questionnaires to measure eating behaviour, eating disorder psychopathology, symptoms of anxiety, depression and stress, social functioning and quality of life at baseline, 4 and 8 weeks. They will also complete momentary assessments using a mobile application (FoodTracker) to report on food intake along with related thoughts, emotions, and behaviours and will wear small, non-invasive sensors to track real-time fluctuations in glucose levels for 15 days. Participants will also perform a food-related go-no go task and a food-related temporal discounting task at baseline, 4 and 8 weeks. Finally, this study will pilot the use of a semi-structured interview to characterise the history of weight, the appetite system, eating-related habits in the family and learning of eating behaviours and attitudes in people with eating or weight disorders.
