About

The aim of this study is to test effectiveness of a new treatment program for adolescents and young adults within the age of 14-21 suffering from AN (MANTR-a) compared to treatment as usual (TAU).

Full description

Anorexia nervosa (AN) is a serious mental illness which leads untreated to aggravation of symptomatology and chronification. Among all mental illnesses, AN has the highest mortality rate, which is about 5.1 per 1000 people per year. High drop-out rates (up to 40%) or small treatment motivation constrains treatment success. Since the onset of AN is mainly in adolescence, it is important to start with therapy as early as possible and establish an effective single-setting treatment program for this age group to prevent chronification.

MANTR-a (Maudsley model of anorexia nervosa treatment for adolescents) is an innovative, theory-based, tailored treatment program which combines a cognitive behavioural approach with motivational interviewing. The main focus of the treatment program is the transformation maintaining factors of AN, like personality aspects, pro-anorexic beliefs, emotion regulation strategies, thinking styles and obstructive behaviour from caregivers.

The aim of this study is the examination ot the effectiveness of the MANTR-a treatment program for adolescents and young adults. Therefore we compare MANTR-a (intervention group) with treatment as usual (control group). Assessments will be conducted before treatment (T0, baseline), after six months (T1), after 12 months (T2) and after 18 months (T3, follow-up) via questionnaires, interviews and neuropsychological measurements. Process evaluation takes place after every session. Each group consists of female adolescents and young adults within the age of 14-21 suffering from AN (ICD-10: F50.0, F50.1), resulting in an overall sample size of 100.

The long-term goal of the study is to provide an evidence-based outpatient treatment for children and adolescents with AN in order to prevent a chronic course of the disease.
