Disordered eating includes both behaviors and cognitions and can cause many of the same negative health outcomes as clinically diagnosed eating disorders (e.g., growth retardation, nutritional deficiencies, and psychosocial disturbances). Compared to the general population, disordered eating is more common in college-age women. An experiment was conducted to test 8 expressive writing interventions in the context of disordered eating. Interventions were drawn from theory-based prevention programs, which included cognitive behavioral therapy, peer and media risk reduction, and cognitive dissonance theory. Dependent variables included emotions (e.g., sadness and hope), evaluation of the expressive writing interventions (e.g., engagement, clarity, ease, and interest), and re-evaluation of disordered eating behaviors and cognitions. Results show that 62.90% of participants had observed disordered eating in their peers. Sadness, with an action tendency related to increased inward evaluation, was the most typical emotional response upon completion of the expressive writing tasks. Interventions that were based on the principles of cognitive behavioral therapy led to the most positive outcomes including engagement and re-evaluation of current disordered eating behaviors and cognitions. Overall, it was concluded that expressive writing interventions are effective in eliciting emotions and causing a re-evaluation of harmful behaviors and cognitions in the context of disordered eating.
