Outcome Measures

Primary Outcomes (2)

  • Response to survey questions measuring attitudes towards sodium claims using 5 point likert rating scales

    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.

    On average the survey took 25 minutes to complete

  • Response to survey questions evaluating participants understanding of sodium claims

    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).

    On average the survey took 25 minutes to complete
