Background There are presently a number of eating disorder treatment interventions that have a research-evidence base to support their effectiveness. However, rates of attrition and treatment outcomes demonstrate that there is no one-size fits all for the treatment of eating disorders. Narrative therapy is a promising, but under-researched, intervention for the treatment of eating disorders (EDs). The aim of this study was to conduct a narrative synthesis of the literature to explore the content and use of narrative therapy in the treatment of EDs. Method Data were extracted from 33 eligible included studies following systematic search of five data bases. Data included aims and objectives, sample characteristics, treatment details and components of narrative therapy, which informed the narrative synthesis. The study is reported according to the Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results Narrative therapy interventions for EDs consisted of several components including the narrative worldview; unpacking the problem story; finding, thickening the meaning and performance of stories hidden by the problem story; and safety considerations. A notable proportion of the extracted articles discussed components of unpacking problem stories, and finding and re-authoring openings (or unique outcomes) that were hidden by problematic stories. Relatively fewer papers discussed the processes by identity shifts were performed or lived out, including in the eating practices of those with a lived ED experience. Furthermore, few papers addressed how therapists established client safety within the narrative framework when working with EDs. Conclusion This narrative synthesis found that narrative practitioners utilise a variety of narrative therapy techniques in working with individuals with a lived ED experience. The current literature has emphasis on specific narrative therapy techniques used in ED treatments, with some aspects of the narrative worldview and safety considerations left undiscussed. Additional research is needed to explore how identity shifts in narrative therapy are performed and lead to measurable behavioural changes, and to consider how safety considerations can be established within the narrative worldview. Plain English summary There are a number of psychological therapies for eating disorders that have research evidence-base. These treatments, however, do not work for everyone as indicated by drop-out rates and eating disorders running a severe and enduring course for some people. Narrative therapy is a therapeutic intervention that has been reported as a promising intervention for people with an eating disorder. The focus of narrative therapy is to engage the person in finding identities hidden by problem-saturated identities and in the performance of these hidden identities. In this review, we have explored the use of narrative therapy for eating disorders to identify what aspects of this therapy are currently being used and which components are less referenced in the literature. Findings from this study support the need for further research into narrative therapy components in the treatment of eating disorders, particularly how hidden identities are performed and safety considerations are integrated into this therapeutic intervention.

Background Narrative therapy has been proposed to have practice-based evidence however little is known about its research evidence-base in the treatment of eating disorders. The aim of this study was to conduct a systematic review of the outcome literature of narrative therapy for eating disorders. Method Treatment outcome data were extracted from 33 eligible included studies following systematic search of five data bases. The study is reported according to Preferred Reporting items for Systematic Reviews and Meta-Analyses guidelines. Results Of the identified 33 studies, 3 reported positive outcomes using psychometric instruments, albeit some were outdated. Otherwise, reported outcomes were based on therapy transcript material and therapist reports. The most commonly reported treatment outcome was in relation to shifts in identity narratives and improved personal agency with a trend towards under-reporting shifts in ED symptoms. Some improvements were reported in interpersonal and occupational engagement, reduced ED symptoms, and improved quality of life, however, there was an absence of standardized measures to support these reports. Conclusions This systematic review found limited support for narrative therapy in the treatment of eating disorders through practice-based evidence in clinician reports and transcripts of therapy sessions. Less is known about systematic treatment outcomes of narrative therapy. There is a need to fill this gap to understand the effectiveness of narrative therapy in the treatment of EDs through systematic (1) Deliveries of this intervention; and (2) Reporting of outcomes. In doing so, the research arm of narrative therapy evidence base will become more comprehensively known.
