Does reading about stroke increase stroke knowledge? The impact of different print materials.

The purpose of this study was to determine whether print materials on stroke resulted in increased knowledge in a sample of lay people. One hundred and seventy-seven participants received (at random) one of five versions of a stroke information packet, or a control packet on colorectal cancer. Participants rated the materials on readability, understandability and usefulness immediately after reading. After a delay of 18 days on average, participants answered questions assessing stroke knowledge. Ratings of all packets were generally positive; however, stroke knowledge scores were significantly higher for the stroke information groups compared to the control group only for knowledge of causal mechanisms (stroke pathophysiology). While there was some indication that the fictionalized material on stroke was more effective than the expository materials, overall the impact of print materials on stroke knowledge, measured after a delay of at least 1 week, was minimal at best. Further research is needed to determine whether fictional contexts make some information more memorable.
