Chapter 10 discusses the prevalence and manifestation of childhood and adolescent eating disorders focusing on Anorexia Nervosa (AN), due to its prevalence. Implementation of maladaptive emotion regulation strategies, with a reduced ability to label and describe emotions leads to the development and propagation of AN. Family based treatments have been widely recognized, as the leading intervention for adolescents with AN, with efficacy rates from 20% to 60%. However, this chapter focuses on a novel approach to AN treatment, centered on emotion regulation in its management, as this may improve treatment outcomes. Programs include: Maudsley Model of Anorexia Nervosa Treatment for Adults and Emotion Acceptance Behavior Therapy, in addition to the modification or adaption of existing, evidence based treatments, such as Radically-Open DBT, although many programs require empirical validation in adolescent samples.
