Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the difference between the five trial arms in behavioral intent to reduce sugar intake. We will use the list randomization method to measure this difference. In each trial arm, participants will be randomly split (at a 1:1 ratio) into a control group or a treatment group. The control group will receive a list of five items. Participants will be asked to state how many of the items they agree with, without revealing which specifc items they agree with. The treatment group will get the same list but with one additional item about added sugars, package information about sugar, daily teaspoons of consumed sugar, soda drinks consumed, and home cooking preference. For each list, the minimum score is zero and the maximum score for the control list is five and six for the treatment list. We will use regression models to estimate the prevalence of each sensitive item. | — |
