Developing the "single-session mindset" in eating disorder research: Commentary on Schleider et al., 2023 "Realizing...

Schleider and colleagues' paper on the application of single-session interventions (SSIs) to eating disorders is timely given the broader focus in mental health on flexible approaches to delivering support at the time the person needs it most. The eating disorder field needs to embrace these innovations including developing a "single-session mindset" with greater attention paid to testing the relevance of SSI for eating disorders. The use of well-powered trials of brief, focused and rapidly scalable interventions is an ideal vehicle for generation and evaluation of new and longer interventions. Our future research agenda needs to carefully consider our target audience, the primary outcome variable of most relevance, and the SSI topic that would be most likely to effect change. Research in prevention might focus on weight concern and evaluation of SSIs that focus on self-compassion or cognitive dissonance related to appearance ideals in the media. Work in early intervention could target denial and disordered eating using SSIs on growth mindset, behavioral activation, and imagery rescripting. Treatment waitlists provide another suitable opportunity, evaluating SSIs that aim to increase hope for change, treatment retention, and kick start early change in therapy, a robust predictor of better treatment outcome.
