Acceptability of Specialist Psychotherapy with Emotion for Anorexia in Kent and Sussex (SPEAKS): A novel intervention for anorexia nervosa

OBJECTIVE

Investigate the acceptability of Specialist Psychotherapy with Emotion for Anorexia in Kent and Sussex (SPEAKS), a novel intervention for anorexia nervosa (AN), conducted as a feasibility trial to provide an initial test of the intervention.

METHODS

SPEAKS therapy lasting 9-12 months was provided to 34 people with AN or atypical AN by eight specialist eating disorder therapists trained in the model across two NHS Trusts in the UK (Kent and Sussex) during a feasibility trial. All participants were offered a post-therapy interview; sixteen patients and six therapists agreed. All patient participants were adult females. Interviews were semi-structured and asked questions around individuals' experience of SPEAKS, the acceptability of the intervention and of the research methods. Interviews were analyzed using thematic analysis.

RESULTS

Key areas explored in line with research questions led to 5 overarching themes and 14 subthemes: (1) shift in treatment focus and experience, (2) balancing resources and treatment outcomes, (3) navigating the online treatment environment, (4) therapist adaptation and professional development, and (5) research processes.

DISCUSSION

SPEAKS was found to be an acceptable intervention for treating AN from the perspective of patients and therapists. The findings provide strong support for delivery of a larger scale randomized control trial. Recommendations for future improvements, particularly pertaining to therapist understanding of the treatment model are detailed, alongside broader clinical implications.

PUBLIC SIGNIFICANCE

We aimed to evaluate the acceptability of a new anorexia nervosa treatment called SPEAKS. Interviews were conducted with patients and therapists involved in the pilot study and responses were analyzed. Results showed that both patients and therapists found SPEAKS to be an acceptable treatment for anorexia nervosa. The study suggests that SPEAKS meets the criteria for moving forward with a larger trial to assess its effectiveness.

Specialist psychotherapy with emotion for anorexia in Kent and Sussex: An intervention development and non-randomised single arm feasibility trial

OBJECTIVE

Anorexia nervosa (AN) is a serious eating disorder treated using psychological interventions, yet outcomes remain limited. Emotional difficulties are recognised as a treatment target. This research programme developed and evaluated feasibility of an emotion-focused therapy for adults with AN.

METHODS

Phase One intervention development utilised 'intervention mapping'. Qualitative research drew on lived experience highlighting objectives for change. Empirical evidence was synthesised into hypotheses of core emotional difficulties and an associated model of change. Relevant psychotherapeutic theory-based change methods were integrated to form the Specialist Psychotherapy with Emotion for Anorexia in Kent and Sussex (SPEAKS) intervention, guidebook and clinician training package. Phase Two tested SPEAKS in a single-arm, multisite feasibility trial across two specialist services, utilising prespecified progression criteria, and embedded process evaluation.

RESULTS

SPEAKS was 9-12 months (40 sessions) of weekly individual psychotherapy, drawing on a range of psychotherapeutic modalities, predominantly Emotion Focused Therapy and Schema Therapy. Forty-six participants consented to feasibility trial participation; 42 entered the trial and 34 completed. Thirteen of 16 feasibility criteria were met at green level and three at amber, highlighting areas for improving model adherence.

CONCLUSIONS

A randomised controlled trial is indicated. Therapist training and guidebook adjustments to improve model adherence are suggested.
