Research is reviewed that evaluates the extent to which psychologists can reduce medical costs of health problems while still maintaining treatment effectiveness. Specific areas on cost-effectiveness include the following: preparation for anxiety provoking medical procedures, smoking cessation, detection and treatment of somatizing patients, psychological intervention in general rehabilitation, rehabilitation of chronic pain patients, behavioral treatment of cardiovascular disorders, and adherence to medical regimens. Major conclusions on these areas are presented. Difficulties with the research are discussed along with areas for future research.
