Effectiveness of an Informational Video for Establishing Students' Basic Knowledge of Post-Stroke Aphasia

The purpose of this study was to investigate changes in knowledge of post-stroke aphasia among students who watched an informational video (Kennedy et al., 2012a) created for this study compared to students who read an informational text (National Aphasia Association, n.d.). Participants included 136 undergraduate and graduate students who completed a pre-test, watched an informational video or read an informational text, completed a post-test, and then completed a maintenance test approximately four weeks later. Results of a one-way mixed ANOVA showed a statistically significant main effect of time, no statistically significant main effect of group, and no statistically significant time-by-group interaction. Both groups demonstrated a substantial increase in knowledge of post-stroke aphasia from pre-test to post-test. These results suggest that the informational video and the informational text may be effective methods to teach students basic information about post-stroke aphasia.
