Validity Evidence of an Educational Video on Cardiac Catheterization for Older Adults.

Cardiovascular diseases represent a significant public health challenge, especially among older adults. Educational strategies that provide clear and accessible information can positively influence outcomes for older patients undergoing invasive procedures such as cardiac catheterization. This methodological study aimed to evaluate the evidence of content and appearance (face) validity of an educational video for older adults undergoing cardiac catheterization. The research was conducted in 3 stages: development of the video based on the 12 principles of the Cognitive Theory of Multimedia Learning; content validation by 11 multidisciplinary experts using the Suitability Assessment of Materials (SAM) instrument; and face validation with 10 older adults assisted in the hemodynamics unit of a university hospital, using the Health Educational Technology Appearance Validation Instrument. The final video consisted of 49 scenes, lasted 5 minutes and 55 seconds, and achieved a global SAM score of 97.1 and an Appearance Validity Index of 0.97. It was considered an appropriate and accessible educational resource by participants. The video constitutes an innovative tool to support health education for older adults and contributes to professional practice in interventional cardiology. Future research should evaluate its effectiveness and verify its impact on hemodynamic parameters, anxiety levels, and adherence to therapeutic guidelines.
