"Finding my own identity": a qualitative metasynthesis of adult anorexia nervosa treatment experiences

Background: The aim of this metasynthesis was to explore adult anorexia nervosa (AN) treatment experiences, including facilitators and barriers to treatment engagement and ways that questions of identity and personal agency were negotiated in treatment contexts. Methods: From 14 qualitative studies that met the search criteria, this thematic synthesis analyzed the sensitized concept of identity in the participants' experiences of AN treatments, including their sense of personal agency, and implications for their recovery. The study was registered with Prospero (ID: CRD42018089259) and is reported according to PRISMA guidelines. Results: Three meta-themes were generated with the following key findings: grappling with identity, where collaborative and tailored interventions were positively experienced; the quality of the therapeutic relationship, which existed in a recursive relationship; and, rebuilding identity that included therapists standing with the person in recovering a sense of identity outside the anorexic identity. Importantly, interventions that failed to be negotiated with the person were experienced as disempowering however, where a two-way trust existed in the therapeutic relationship, it critically empowered and shaped participants' sense of identity, and broadened the perception that they were valuable as a person. Conclusions: There was consensus across the range of treatment contexts that individuals with a lived AN experience preferred treatments where they experienced (1) a sense of personal agency through tailored interventions; and (2) therapists who treated them as a person who, in the face of their struggles, had skills and capacities in the processes of recovering and rebuilding sustainable and preferred identities outside the AN identity.
