Efficacy of a therapist-guided smartphone-based intervention to support recovery from bulimia nervosa: Study protocol of a randomized controlled multi-centre trial.

This is the first randomized controlled trial to examine a guided smartphone-based aftercare intervention following inpatient treatment of patients with BN. We expect that this innovative aftercare intervention is highly accepted by the patients and that it has the potential to support recovery after inpatient treatment and thereby could contribute to improving aftercare for patients with BN.
