The goal of this observational study is to compare short and long-term effects of manualised Family Based Treatment for adolescent anorexia nervosa to those of non-manualised family therapy. The study will approach former patients who were treated before and after Family Based Therapy was adopted in an outpatient clinic, and extract data from electronic health records and public registries.
A two-group retrospective exploratory cohort study with longitudinal follow-up comparing adolescents with anorexia nervosa treated with generic family therapy to those treated with the manualised Family Based Treatment (FBT). The primary aim is to investigate whether adoption of FBT has led to faster normalisation of weight and lower rates of eating disorder in early adulthood. Secondary aims are to investigate whether implementation of FBT has changed the time to discharge, heterogeneity of patient weight change across treatment, rates of adverse events, rates of readmission, patient experiences of the treatment, long term functional outcomes and mortality. Data are extracted from patient health records, reported by participants and extracted from public registries.
