Description: The study looked at tools that include interactive computer discs, videotapes, audiotapes, brochures, and computer-generated fact sheets to help patients make decisions about medical screening and treatment. According to the study, most research has looked more at the effects of the tools on patient knowledge and satisfaction than on patient-clinician communications and health behavior and outcomes.
