The development of co-designed parent-supported cognitive behaviour therapy for perfectionism in adolescents with eating disorders: initial feasibility and acceptability.

Background: Perfectionism is significantly associated with symptoms of eating disorders in adolescents. Studies to date have not examined parent-supported CBT for perfectionism in eating disorders (CBT-P-ED). We co-designed the treatment and conducted a feasibility trial. Methods: Eight parents of adolescents with eating disorders (M age = 48.75 years, 100% female) engaged in three co-design workshops to create a parent-supported CBT-P-ED self-help intervention. A further 10 parents (M age 41.8 years, 50% female) and their adolescent offspring (n = 10, M age 15.4 years, 60% female, 50% with self-reported diagnosis of anorexia nervosa) participated in a feasibility trial and provided feedback on the intervention. Results: The parents who engaged in the co-design workshops suggested several areas to optimise the perfectionism intervention, including using plain language, the impact of parental perfectionism, how to engage with their adolescent in treatment and the importance of increasing eating disorder specific material. Feedback from the feasibility trial suggested that the intervention was acceptable and feasible with 100% of parents and adolescents saying it was useful, and no attrition. Conclusions: Parent-supported CBT-P-ED appears to be feasible. Future research is now required in a randomised controlled trial. Plain English Summary: It has been repeatedly demonstrated that perfectionism can contribute to a variety of health issues. Perfectionism is a process centered on intense self-pressure to meet high standards, which has a significant impact on how an individual views themselves. Perfectionism is more prevalent in individuals with eating disorders than in those without it. There is a strong link between perfectionism and the onset of eating disorders, as well as an increase in disordered eating symptoms and a lower rate of recovery. There is currently no treatment available that addresses perfectionism in both parents and young people. The aim of the project was to work with parents and carers to co-design a parent-supported self-help program for young people that addresses perfectionism in eating disorders. We conducted three co-design workshops, followed by a four-week feasibility study to determine suitability and feedback on the intervention. The goal was to develop an intervention which can offer caregivers and young people easily available support that may aid in their understanding of perfectionism. It is hoped that by addressing perfectionism in young people with eating disorders, this approach will help them recover and thrive. [ABSTRACT FROM AUTHOR]
