Maudsley Family Therapy (MFT), and its manualised version, Family-Based Therapy (FBT), are the only well-established treatment interventions for adolescent anorexia nervosa (AN), with treatment efficacy primarily measured by improvements in eating behaviours and weight restoration. A crucial component of this therapy is an intensive home-based refeeding intervention that requires a substantial commitment from parents for up to one year. While this treatment works to restore weight in a proportion of adolescents, very little is known about its impacts on family distress, relationships and identity, including in the 40% of families where the adolescent experiences ongoing eating disorder (ED) symptomatology and/or psychological distress during and post-treatment. Specifically, few studies have investigated the impacts of MFT/FBT treatment on family functioning or on how parents negotiate their identities, or who they understand themselves to be, in the context of this treatment intervention. This is a significant omission, given the substantive role assigned to parents to take responsibility for their child's eating restoration in the first treatment phase. This study seeks to address this gap through a qualitative exploration of parents' experiences of MFT/FBT, in cases where treatment was discontinued and/or their child continued to experience psychological distress post-treatment.
