Abstract TP168: Efficacy of a Pictogram to Promote Stroke Knowledge Among Illiterate Korean Elderly

Background and Purpose: Extensive research supports the importance of knowledge in stroke prevention and reducing prehospital delay time. However, the level of stroke knowledge among Korean older adults remains low. In particular, older adults who are illiterate lack of stroke information despite being at high risk. The purpose of this study was to develop and examine the efficacy of a pictogram to enhance stroke knowledge in the high-risk and illiterate older adults. Methods: We conducted a pretest-posttest nonequivalent control group design study and compared differences in stroke knowledge before and after the intervention. A total of 117 older adults (82 in the intervention group and 35 in the control group) who were 60 years and older residing in community participated in the study. Participants in the intervention group received a pictogram-based education, while participants in the control group received a powerpoint-based education. Stroke knowledge was measured by structured survey questionnaires. Descriptive statistics for sample characteristics, repeated measure ANOVA for the efficacy, and independent t-test for satisfaction comparison between groups were used. Results: The intervention group showed a higher increase in stroke knowledge (F=16.45), awareness of risk factors (F=15.71), stroke warning signs and symptoms (F=17.29), and action at stroke (F=19.36) compared to the control group at p Conclusions: The data revealed that a pictogram-based education is more effective than a powerpoint-based education among illiterate older adults. Replicated studies with this pictogram in a larger randomized controlled trial is warranted, which may give greater validity to our findings. Future longitudinal research is recommended to examine retention of stroke knowledge over the long term.
