- Primary Outcome Measures
Name Time Method Contribution of the different front-of-package labeling (FOPL) schemes to improving the decision of participants to buy the least harmful option more often, the selection of the least harmful option more often and the correct identification of sugars, sodium and/or saturated fats found to be in excess in the products more often, measured comparing correct responses of participants to the stimuli in different experimental/control groups at one timepoint
- Secondary Outcome Measures
Name Time Method The impact of sociodemographic variables, such as gender, age, and education level, on the differences observed in the performance of various front-of-package labeling schemes. This assessment was measured by administering a structured questionnaire to respondents after they were shown mock-up products and provided their responses. The questionnaire captured their opinions and perceptions of the labeling schemes at one timepoint. The goal was to determine the extent to which sociodemographic factors contribute to the variations observed in the respondents' evaluations of the labeling schemes.
