• Registration Number: NCT05735457
• Lead Sponsor: University Hospital Freiburg

Brief 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.

Arm && Interventions

Group	Intervention	Description
Intervention Arm	A short, animated storytelling video on dietary sodium	Participants will be shown a short, animated storytelling (SAS) video on dietary sodium and thereafter be asked to complete a questionnaire to assess knowledge on dietary sodium and behavioral expectation. Two weeks later, participants will once again be asked to complete the knowledge and behavioral expectation questionnaire.
Attention Placebo Control Arm	A short, animated storytelling attention placebo video	Participants will be shown a attention placebo control (APC) video, unrelated to the outcomes measured in this trial, before being asked to complete the knowledge and behavioral expectation questionnaire. Two weeks later, participants will once again be asked to complete the knowledge and behavioral expectation questionnaire.

Primary Outcome Measures
