简要总结
The goal of this experiment is to examine the effects of 2 types of non-nutritive sweetener (NNS) warning labels among a sample of Chilean parents. The main questions this experiment aims to answer are:
Do non-nutritive sweetener warning labels improve consumers' ability to identify when a product contains non-nutritive sweeteners?
Do non-nutritive sweetener warning labels impact on consumers' selection of non-nutritive sweetener-sweetened, unsweetened, and/or sugar-sweetened products for their children?
Participants will be randomly assigned to 1 of 3 types of labels and view their assigned label on 3 sets of products. Each set will display 4 similar products: one unsweetened, one sweetened with sugar, one sweetened with non-nutritive sweeteners, and one sweetened with both sugar and non-nutritive sweeteners. For each set, participants will identify which product(s) contain NNS and select the product that they would purchase for their child. Researchers will compare results across label types.
详细描述
Participants will complete an online randomized experiment programmed in Qualtrics. After providing informed consent, participants will be randomly assigned to view 1 of 3 types of labels: a neutral control label, a rectangular label stating "contains non-nutritive sweeteners, not recommended for children" (i.e., Chilean NNS label), or an octagonal label stating "contains non-nutritive sweeteners" (i.e., Colombian NNS label).
Participants will view their assigned label on 4 similar products (one unsweetened, one sweetened with sugar, one sweetened with non-nutritive sweeteners, and one sweetened with both sugar and non-nutritive sweeteners) displayed in random order and complete a task where they identify which product(s) contain non-nutritive sweeteners and select one of the products to purchase for their child. During this task, in all arms, products will also display Chile's current nutrient warning labels when applicable. This task will be repeated 3 times, each time with a different product category (i.e., fruit drinks, yogurts, breakfast cereals), with categories displayed in random order.
After the selection/identification tasks, participants will view their assigned labels on 2 products containing non-nutritive sweeteners (i.e., flavored milk and cereal bar). For each product, participants will rate the perceived message effectiveness of the label and perceived product healthfulness. Lastly, after all product exposures, participants will rate their intentions to limit their child's non-nutritive sweetener consumption.

结局指标
主要结局
Correct identification of non-nutritive sweetener containing products
时间窗: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Correct identification of products that contain non-nutritive sweeteners will be measured by survey. Response will be coded in a dichotomous 0-1 range, where 1 indicates that the participant correctly identified the products that contained non-nutritive sweeteners and 0 indicates that the participant did not correctly identify the products that contained non-nutritive sweeteners.
Selection of non-nutritive sweetener-sweetened product for purchase
时间窗: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Selection of sugar-sweetened product for purchase will be measured by survey. Response will be coded in a dichotomous 0-1 range, where 1 indicates that the participant chose one of the non-nutritive sweetener-sweetened products and 0 indicates that the participants selected one of the other two products.
Selection of unsweetened product for purchase
时间窗: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Selection of unsweetened product for purchase will be measured by survey. Response will be coded in a dichotomous 0-1 range, where 1 indicates that the participant chose the unsweetened product and 0 indicates that the participants selected one of the other three products.
Selection of sugar-sweetened product for purchase
时间窗: During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.
Selection of sugar-sweetened product for purchase will be measured by survey. Response will be coded in a dichotomous 0-1 range, where 1 indicates that the participant chose one of the sugar-sweetened products and 0 indicates that the participants selected one of the other two products.
次要结局
- Perceived message effectiveness, mean score(During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.)
- Perceived product healthfulness, mean score(During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.)
- Relative product healthfulness, mean score(During exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.)
- Intentions to limit non-nutritive sweetener consumption, mean score(After exposure to intervention (i.e., study stimuli), assessed during one-time online 10-minute survey.)
