Impacts of Prolonged Exposure to Added Sugar Warning Labels on Explicit Weight Bias: a Randomized Controlled Trial

Explicit weight bias, mean score

时间窗: Assessed via survey after exposure to intervention (i.e., shopping task) 2 times approximately 4 weeks apart (i.e., in visits 1 and 4)

Explicit weight bias will be measured by survey through seven items. Items will present participants with pairs of antonyms and ask that they select the box between antonyms that they feel best describes their feelings and beliefs about people with obesity: (1) lazy - hard-working, (2) no will power - has will power, (3) good self - control - poor self-control, (4) active - inactive, (5) self-indulgent - self-sacrificing, (6) dislikes food - likes food, (7) undereats - overeats. Response options, which will be presented as 5 boxes between antonyms, will be coded in a categorical 1-5 range, where higher scores represent higher endorsement of a stereotype that contributes to weight bias. Each participant's responses to each item will then be averaged across the seven items to obtain their final score on the outcome in a 1-5 range, where higher scores represent higher explicit weight bias.
