Recurrent Abdominal Pain (RAP) is one of many disorders in adults and children for which there is no identifiable organic or physiological cause, yet which is associated with illness behavior that has significant societal and personal costs. Although 10-15% of children have RAP, there is at present no accepted medical or behavioral treatment for it. We have conducted a series of studies that suggests that illness behavior is, at least in part, learned during childhood when parents model sick role behavior or respond to their children's somatic complaints in a way that encourages or reinforces sick role behavior. The goal of this project is to evaluate the efficacy of a social learning and cognitive behavior therapy approach for treating children with RAP.
