Abstract:	Introduction: As smartphones are widely distributed nowadays, mental health apps seem to be a promising treatment tool. First self-help apps for eating disorders have been developed recently. However, studies assessing the efficacy of such apps are scarce. A smartphone app could prevent further weight reduction and increase commitment during waiting time for outpatient treatment, especially for adolescents with anorexia nervosa (AN). In this study protocol, a randomised controlled trial to assess the efficacy of a smartphone-enhanced low-threshold intervention for AN during waiting time is described. Methods and analysis: 30 adolescents with AN aged 12–19 years will be recruited at three child and adolescent psychiatry centres in Germany. All participants will be randomised to consultations only or consultations and the use of the Jourvie Research app. The app will be installed either on their own smartphone or on a research device. The participants will receive biweekly to monthly consultations for 3 months to review meal plans and weight management with a clinician. In addition, the Jourvie Research app for meal, behaviour and emotion protocolling will be provided to the intervention group. The protocols will be discussed with a clinician during the consultations. Dialectical behaviour therapy-informed skills for tension regulation to increase compliance with the meal plan will be taught in the intervention group and the app will remind the participant of a skill in a moment of need. The primary outcome is the age-adjusted and height-adjusted weight gain in standard deviation score after 3 months. Ethics and dissemination: Results will be disseminated at conferences and through peer-reviewed publications. The trial was approved by the ethics review board of the local medical association, Mainz, Germany, under the reference number 837.338.15. Trial registration number: German clinical trials register, reference number DRKS00008946.
