The goal of this randomized, controlled clinical trial is to determine the efficacy of combined behavioral and drug treatment of CDH in youth ages 10 to 17. In the study, scientists will investigate if a combination of pain coping skills training (CST) and the drug amitriptyline (AMI)——CST-AMI——is effective in reducing headache frequency, functional disability, and symptoms of depression. More specifically, the researchers will evaluate if CST-AMI is superior to AMI combined with an attention control (ATT). The CST will mainly focus on learning skills for coping with pain, and the ATT will focus on understanding chronic headaches and lifestyle information.
