Extending single-session interventions to target parents as agents of change in adolescent eating disorders.

Schleider et al. (2023, International Journal of Eating Disorders, current issue) propose multiple applications of single-session intervention (SSI) models to the eating disorders (EDs) intervention spectrum. In this commentary, we propose extending the potential of SSIs to target parents as agents of change for youth with restrictive EDs, particularly anorexia nervosa (AN). Directing SSIs to parents of children with AN can circumvent psychological barriers to care while capitalizing on the unique level of motivation in a parent to protect a child and advance their capacity to thrive. Key design components of effective SSIs map well onto the core principles of family-based treatment (FBT), which can be distilled to inform the development of SSIs for parents of youth at risk or exhibiting emerging or diagnostic AN. The participatory action research framework highlighted by Schleider et al. (2023) speaks to the importance of developing SSIs using co-design methodologies with parents. Doing so reflects the FBT principle of parent empowerment, acknowledges the research on parental self-efficacy as a mediator of FBT, and recognizes parents as both key stakeholders in the prevention and treatment of child and adolescent EDs, and as the intended recipients of the SSIs created for this population. PUBLIC SIGNIFICANCE: Schleider et al.

In this commentary, we extend the potential of SSIs to target parents as agents of change for youth with restrictive EDs. Parent-focused SSIs can circumvent psychological barriers to care while capitalizing on the unique level of motivation in a parent to advance their child's capacity to thrive.
