This guide investigates the efficacy of cognitive dissonance-based interventions in preventing the development of eating disorders among high-risk populations. Authors Eric Stice and Katherine Presnell, both established researchers in the field of eating disorder prevention, present a structured, evidence-based program designed for clinical facilitators. The text outlines a specific protocol that encourages participants to challenge the 'thin ideal' through active engagement, thereby reducing the psychological pressure that often precedes disordered eating behaviors.

Clinicians and researchers frequently cite this manual as a primary resource for implementing dissonance-based prevention programs in school and clinical settings. Experts highlight the text for its clear, actionable structure and its reliance on rigorous clinical trials to validate the proposed methodology.
