Purpose: To test the effectiveness of a video to teach patients about prostate cancer screening and treatment in a clinic setting.Methods: A staged, two-group, pretest-posttest quasi-experimental design was used. Questionnaires were completed before and after a routine doctor's appointment in a Veteran's Administration clinic. The experimental group (n = 52) viewed the video, and the control group (n = 52) received usual care only. The two groups were similar in age, education, race, and quality of life.Results: Knowledge increased significantly from pretest to posttest for the experimental group, but not for the control group (p < .001). More patients in the experimental group changed their preference for prostate-specific antigen (PSA) screening (31% experimental vs. 2% control, p = .002), indicating the patients were impacted by the information presented. Viewing the video did not stimulate increased discussion with the physician or lengthen appointment time.Conclusion: The video was effective in improving knowledge about a complex topic and changing some patients' preference for PSA testing without frightening or confusing patients.
