Therapists' perspectives on the Maudsley model anorexia nervosa treatment for adolescents and young adults (MANTRa): A qualitative interview study.

Objectives: A rising incidence of eating disorders in the young population and limited effectiveness of available treatment approaches underscore the need for innovative therapies. This study explores therapists' perspectives regarding a promising new manualized psychotherapeutic treatment (MANTRa) for adolescents and young adults with anorexia nervosa (AN).

Methods: Semi-structured qualitative interviews were conducted with 10 therapists (nine female) who provided 24-34 sessions of MANTRa per patient. Interview topics included positive and negative experiences with MANTRa in general, with the workbook and other components. Reflexive thematic analysis was used to interpret the data. Furthermore, written notes taken by the therapists after each sessions were analysed.

Results: The thematic analysis revealed five overarching themes: (1) Variety of therapeutic tools and content elements included in the workbook; (2) Getting the therapeutic process going; (3) Flexibility in use of the workbook; (4) Impact of the scientific and multidisciplinary framework on quality assurance; (5) Formal design of the workbook. Therapists' case formulation letters to the patients were regarded as powerful tools to strengthen therapeutic alliance and promote recovery. In-depth therapists' training, regular supervision and a multi-professional treatment setting were important factors to ensure high treatment quality.

Conclusions: The findings suggest how the MANTRa content (e.g. inclusion of additional therapeutic tools), the therapists' training and the format (e.g. provision of a digital version) can be improved to reach maximum impact. Therapists' formulation letters may be an effective therapeutic tool not only for AN but also across the spectrum of psychiatric disorders in adolescents and young adults.
