Temperament-Based Treatment for Young Adults with Eating Disorders: Acceptability and Initial Efficacy of an Intensive, Multi-Family, Parent-Involved Treatment.
Abstract Background: Adult eating disorder treatments are hampered by lack of access and limited efficacy. This open-trial study evaluated the acceptability and preliminary efficacy of a novel intervention for adults with eating disorders delivered to young adults and parent-supports in an intensive, multi-family format (Young Adult Temperament-Based Treatment with Supports; YA-TBT-S). Methods: 38 YA-TBT-S participants (m age = 19.58; SD 2.13) with anorexia nervosa (AN)-spectrum disorders, bulimia nervosa (BN)-spectrum disorders, and avoidant/restrictive food intake disorder (ARFID) completed self-report assessments at admission, discharge, and 12-month follow-up. Assessments measured program satisfaction, eating disorder psychopathology and impairment, body mass index (BMI), and trait anxiety. Outcomes were analyzed using linear mixed effects models to examine changes in outcome variables across diagnoses over time. Results: Treatment was rated as highly satisfactory. 53.33% were in partial or full remission at 12-month follow-up. Participants reported reductions in ED symptomatology (AN and BN), increases in BMI (AN and ARFID), and reductions in clinical impairment (AN and ARFID) at 12-month follow-up. Conclusions: YA-TBT-S is a feasible and acceptable treatment that may improve ED outcomes in young adults with a broad range of diagnoses. Further evaluation of efficacy is needed in larger samples, and to compare YA-TBT-S to other ED treatment approaches.
