The promise of single-session interventions to inform stepped care approaches for complex mental health problems: Commentary on Schleider et al. (2023).

Schleider et al. (2023, International Journal of Eating Disorders) provide an overview and compelling rationale for incorporating single-session interventions (SSIs) into the eating disorder field. As intervention researchers working with complex mental health problems, including suicide risk, we agree that there is much to be gained by developing and deploying SSIs on a broader scale and for historically difficult-to-treat problems. In this commentary, we describe some additional strengths of the SSI approach and highlight their potential in the use of stepped care models of treatment. Ultimately, determining who could benefit from a low dose of treatment and for whom longer treatment is warranted could pave the way for addressing the current mental health burden.
