About this trial
The study seeks to examine how characters on packaging and warning labels affect purchase intentions and risk perception among children aged 12 to 17 in Colombia and, examine whether characters' presence weakens or reduces the perceived message effectiveness of the warning labels' impact. This will be a 2x2 between-subjects experiment manipulating presence or absence of characters and presence or absence of warning labels. Participants will be randomly assigned to 1 of 4 conditions in an online survey programmed in Qualtrics.
