Intensive family exposure-based cognitive-behavioral treatment for adolescents with anorexia nervosa.

Background: Anorexia nervosa exhibits high comorbidity rates and shared features with anxiety disorders and obsessive-compulsive disorder. Anxiety-based etiological models have proposed that fear of eating-related stimuli is the central mechanism around which avoidance of food and food-related rituals are performed. Building on this approach, exposure-based interventions have demonstrated promising results.
