Clinical Trial Summary

This study will evaluate the effect of a short, animated storytelling intervention video on sodium intake as a major risk factor for cardiovascular disease on immediate and medium-term retention of knowledge about the risks of cardiovascular diesaes due to increased sodium intake. We will also measure voluntary engagement with the content of the short, animated storytelling intervention video on positive psychological capital. In this 4-armed, parallel, randomized controlled trial, 10,000 adult, US participants will be randomly assigned to (1) a short, animated storytelling intervention video on sodium as a cardiovascular disease risk factor followed by surveys assessing the facts om sodium and cardiovascular disease conveyed in the video (2) the surveys only, (3) an attention placebo control video followed by the before mentioned surveys, and (4) an arm that is exposed to neither the video nor the surveys. Two weeks later, participants in all four arms will complete all of the surveys. The primary outcome is knowledge about the cardiovascular disease risk associated with increased sodium intake (immediate and medium-term). The major scondary outcome is the extent of voluntary engagement with the short, animated storytelling video content.
