简要总结
The goal of this experiment is to examine the effects of three different types of front-of-package warning labels for sugar-sweetened beverages on perceived weight stigmatization, as well as the effect of making such labels more weight-neutral. The main questions this experiment aims to answer are:
- Are certain types of front-of-package warning labels perceived as more stigmatizing than others?
- Are more weight-neutral versions of front-of-package warning labels perceived as less stigmatizing than their regular versions?
- Is there a trade-off between label effectiveness in discouraging product consumption and perceived weight stigmatization?
Additionally, this experiment also aims to answer the following questions:
- Does exposure to certain types of front-of-package warning labels lead to changes in participants' weight bias?
- Are changes in participants' weight bias as a result of label exposure mediated by attribution of personal responsibility for body weight, pathogen disgust, or perceived social consensus?
详细描述
Participants will be randomly assigned to see one of four types of labels: control labels, nutrient warning labels, text-only health warning labels, or graphic health warning labels. Participants will then see an image depicting different types of fictional sugar-sweetened beverages carrying the label type that they were assigned to. Participants will see this image twice, in random order, each time differing in whether the label is weight-neutral or not (i.e., whether the label references calories/obesity or not). Each time, participants will answer survey questions about the label. Last, participants will answer survey questions measuring their weight bias and potential mediating variables.

结局指标
主要结局
Perceived weight stigmatization, mean score
时间窗: Immediately after exposure to intervention (i.e., study stimuli), assessed during one-time online study survey.
Stigmatization of people with obesity will be measured by survey through a three-item scale. Items will inquire about how much participants perceive the label to (1) stigmatize people with obesity, (2) promote negative stereotypes about people with obesity, and (3) portray people with obesity in a disrespectful manner. Response options will be on a 1 to 5 scale, with higher scores representing a higher perceived weight stigmatization by the study labels. Each participant's responses to each item will be combined to obtain their final score on the outcome.
