Eating disorders are severe, life-threatening psychological disorders that frequently manifest in children and adolescents. This chapter provides an overview of the prevalence, epidemiology, assessment, and treatment of the six child and adolescent feeding and eating disorders covered by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders: pica, rumination disorder, avoidant/restrictive food intake disorder, anorexia nervosa, bulimia nervosa, binge-eating disorder, and other specified feeding or eating disorder. Existing research is limited, but the most evidenced treatments, depending on disorder, are applied behavioral analysis; individualized behavior plans; family-based therapy; cognitive behavioral therapy; and self-help. Given the limited number of randomized controlled studies and the moderate (at best) recovery rates, future research should investigate possible adjunctive treatments (i.e., cognitive remediation therapy, dialectical behavior therapy); adaptations for specific populations; and dissemination and implementation improvements (i.e., phone or Internet delivered interventions).
