A Short, Animated Storytelling Video to Increase Knowledge About Sodium Intake as a Cardiovascular Risk Factor
Study Details
Study Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Intervention Arm 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. |
Other: A short, animated storytelling video on dietary sodium
Participants in the Intervention Arm will view a short, animated storytelling video on dietary sodium and the risks of cardiovascular disease due to increased intake of sodium.
|
| No Intervention: Exposed Control Arm Participants will be asked to complete a questionnaire to assess knowledge on dietary sodium and behavioral expectation (the same questionnaire as in arm 1, however, without being exposed to the SAS video on dietary sodium before. Two weeks later, participants will once again be asked to complete the knowledge and behavioral expectation questionnaire. |
|
| Placebo Comparator: Attention Placebo Control Arm 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. |
Other: A short, animated storytelling attention placebo video
The Attention Placebo Control Arm will view an attention placebo control video, unrelated to the outcomes measured in this trial.
|
| No Intervention: Un-exposed Control Arm Participants will not view a video and will not be asked to complete the questionnaire. Two weeks later, participants will once again be asked to complete the knowledge and behavioral expectation questionnaire. |
Outcome Measures
Primary Outcome Measures
- Immediate effect of the short, animated storytelling intervention video on knowledge about dietary sodium as a cardiovascular risk factor [immediately after watching the video]
The immediate effect of the short, animated storytelling intervention video on knowledge about dietary sodium as a cardiovascular risk factor assessed by a sodium questionnaire containing 30 questions.
- Medium-term effect of the short, animated storytelling intervention video on knowledge about dietary sodium as a cardiovascular risk factor [2 weeks after watching the video]
The medium-term effect of the short, animated storytelling intervention video on knowledge about dietary sodium as a cardiovascular risk factor assessed by a sodium questionnaire containing 30 questions.
Secondary Outcome Measures
- Immediate effect of the short, animated storytelling intervention video on behavioral expectation to reduce dietary sodium. [immediately after watching the video]
The immediate effect of the short, animated storytelling intervention video on behavioral expectation to reduce dietary sodium assessed by a questionnaire containing 30 questions on behavioral expectation.
- Medium-term effect of the short, animated storytelling intervention video on behavioral expectation to reduce dietary sodium. [2 weeks after watching the video]
The medium-term effect of the short, animated storytelling intervention video on behavioral expectation to reduce dietary sodium assessed by a questionnaire containing 30 questions on behavioral expectation.
- Voluntary post-trial engagement (frequency) with the video content. [2 weeks after entering the trial]
Assessment of the frequency (absolute number) of watching the trial videos after completion of the trial questionnaires
- Voluntary post-trial engagement (duration) with the video content. [2 weeks after entering the trial]
Assessment of the duration (in minutes) of watching the trial videos after completion of the trial questionnaires
