Internet-Based Interventions for Eating Disorders
Evidence demonstrating the efficacy of treatment and prevention programs for eating disorders is accruing. However, the common face-to-face delivery of these interventions has a number of limitations, including high cost and limited accessibility. E-mental health, referring to the use of information and communication technology—particularly the Internet—in interventions for mental health disorders, has the potential to overcome these barriers and enhance the treatment and prevention of eating disorders. To date, the limited number of evaluations have documented small to moderate effect sizes in the improvement of eating disorder symptomatology through Internet-based treatment and prevention. Beyond efficacy, major questions remain regarding content, structure, and modes of delivery of Internet-based interventions; suitable diagnostic tools and safety measures; and cost-effectiveness, dissemination, and implications for public health programming. These aspects deserve attention in future research before widely recommending Internet-based interventions for eating disorders.
