Arm && Interventions

Group	Intervention	Description
Canadian Consumer Monitor Panel	Mock package questionnaire	Canadian Consumer Monitor Panel is a online consumer monitor panel which answers surveys every 8-10 weeks about diet and health.

Primary Outcome Measures

Name	Time	Method
Response to survey questions measuring attitudes towards sodium claims using 5 point likert rating scales	On average the survey took 25 minutes to complete	Within an online survey, participants were exposed to 4 mock soup packages that differed only by the claim it carried. After being exposed to each mock package, participants were asked to rate their perceived attractiveness, healthiness, credibility, usefulness of the tested sodium claims using 5 point likert scales. Participants were also asked to rate their purchasing intentions of the mock soup product with the different sodium claims.
Response to survey questions evaluating participants understanding of sodium claims	On average the survey took 25 minutes to complete	After each mock package, understanding of sodium claims was evaluated using various survey methods. First, participants were asked to rate their perceived clarity of the wording of the claim using a 5 point likert scale (a subjective measure of understanding). Second, participants were ask to rate, on 5 point likert scales, the perceived benefit of consuming the mock package for subgroups with different health conditions (an indirect measure of understanding). Finally we asked participants, in an open ended question, to explain what a claim means to a friend (an objective measure of understanding).
