Brief summary
This randomized controlled trial will assess the effects of External Cues focused messaging (i.e., government recommendations of MyPlate) compared to Internal Cues focused messaging (i.e., intuitive eating). The investigators will collect data on within-person changes in psychological (e.g. affect) and physiological (e.g. heart rate variability) outcomes in female college students. Participants will be randomly assigned to one of two study conditions. In condition one, participants will view a five-minute video focusing on traditional nutrition education principles. In condition two, participants will view a five-minute video focusing on intuitive eating principles.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Heart Rate Variability (HRV) | HRV will be measured during a 3-minute baseline period and while watching a 5-minute intervention video. | Heart rate variability measures the variation in time between each heartbeat. This will be measured using Firstbeat Electrocardiograms (ECGs) that participants will attach to their chest using two electrodes. |
| Change in Affect | The PANAS is administered before and immediately after viewing the video. | Affect will be assessed using the Positive and Negative Affect Schedule (PANAS), an instrument that asks participants to rank the extent to which they are feeling each of 20 different emotions on a scale of 1-5. The PANAS produces a score from 10-50 for each Positive Affect and Negative Affect, with higher scores indicating higher levels of these states. |
