For children and adolescents, a review of RCTs evaluating the effectiveness of psychological therapy for the management of chronic and recurrent pain found that psychological treatments are effective in reducing pain when people under 18 years old have headaches. This beneficial effect may be maintained for at least three months following the therapy. Psychological treatments may also improve pain control for children or adolescents who experience pain not related to headaches. It is not known if psychological therapy improves a child or adolescents mood and the potential for disability related to their chronic pain.
