Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Temporal discounting (TD) rate: the rate at which individuals discount rewards as a function of time. Temporal discounting is measured at baseline (before the intervention), immediately after the intervention, and 1 week later at follow up. Temporal Discounting is assessed via a questionnaire that asks the participant's preference for one monetary option over another (e.g. $500 in one year, or $100 now). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Food Demand. Food demand is measured at baseline (before the intervention), immediately after the intervention, and 1 week later at follow-up. Food demand is assessed via a questionnaire that asks the participant how many servings of a snack option (e.g. an apple or candy bar) the participant would purchase if the snack option cost a certain amount. The cost options are varied (e.g. $1 or $1.25) and used to estimate what a participant would be willing to pay for a snack option. 2. Food Choice. Food choice is assessed immediately after the intervention and at follow-up 1 week later. Participants are presented with various healthy and unhealthy snack options and are told that they can select as many snack options as they would like to either eat or take with them. Their choices are recorded. | — |
