Summary

Binge eating disorder (BED) is a common and disabling eating disorder (ED) which has significant effects on psychological wellbeing, physical health, and quality of life. Talking therapies, most notably cognitive behaviour therapy (CBT), are presently recommended for the treatment of BED. However, outcomes from treatment are inadequate. Therefore, there is a need for development of new treatments.

This study aims to investigate the feasibility of combining Attention Bias Modification Training (ABMT) and Transcranial Direct Current Stimulation (tDCS) to reduce binge-eating behaviour and craving for food in people with BED.

ABMT is a computerised training that seeks to alter responses towards food that people are not consciously aware of. During ABMT, participants are trained to 'look towards' low-calorie food and 'look away' from high-calorie food. TDCS is a safe, well tolerated, non-invasive form of brain stimulation which is suitable for supervised self-administration. It stimulates specific brain areas using a mild electrical current (2 mA) via small electrodes placed on the scalp. In this study, participants will be randomly allocated to receive either ABMT with real tDCS or ABMT with sham tDCS. ABMT and real/sham tDCS will be delivered simultaneously, i.e. participants will engage in ABM training whilst receiving tDCS. All participants will be remotely supervised by the study researcher for the duration of each treatment session.

Biological male and female adults (aged 18-60) of any gender will be eligible to take part if they have a DSM-V of BED and they are overweight or obese.

Taking part will involve completing 10 sessions of combined ABMT and real or sham tDCS over 2-3 weeks. Binge frequency, food craving and other outcomes will be measured at the start of the study, end of the study, and at the 6-week follow-up.

Conditions

  • Binge-Eating Disorder

Interventions

OTHER

Simultaneous Attention Bias Modification Training and Transcranial Direct Current Stimulation (tDCS)

Participants will receive 10 sessions of computerised attention bias modification training with either real or sham tDCS. Participants will self-administer tDCS at home, with research supervision, and complete attention bias modification training on a laptop or desktop computer while receiving stimulation. Sessions will be completed week daily for 2-3 weeks.
