Assessing the efficacy of an educational video on stroke knowledge in Lebanon: a single-arm interventional study

Abstract

Abstract Objective This study aimed to assess the public’s knowledge of stroke before and after viewing an educational video about stroke risk factors, preventive measures, and alarming signs. Methods A single-arm interventional study was conducted in Lebanon using a 3-minute video-based education about stroke. A pre- and post-structured questionnaire compared the level of knowledge about stroke. Results The study included 685 participants. Knowledge of stroke, risk factors, warning signs, treatment, and preventive measures significantly increased post-educational video sessions. A higher baseline knowledge score was associated with a family history of stroke (Beta = 1.76) and being a healthcare professional (Beta = 3.35). Participants between 25 and 34 years (Beta=-1.39) and those with a high risk of stroke (Beta=-1.03) were significantly associated with a lower knowledge score. Conclusion This study demonstrated the effectiveness of a video-based educational tool to raise awareness about stroke. Short, targeted audio-visual resources using lay language can convey health education messages and influence behavioral changes. The community can benefit from a large-scale educational campaign that targets different socio-economic statuses to enhance knowledge of stroke and save lives.
