简要总结
This study aims to examine consumer responses to traditional and counter-marketing messages discouraging sugary drink consumption, including effects on intentions to consume sugary drinks and perceived weight stigma. Because prior research has suggested that counter-marketing may be especially effective among younger populations, the investigators will examine effects overall and by age group (young adults [ages 18-29 years] vs. middle and older adults [ages 30+ years]).
详细描述
In this online randomized clinical trial, participants will be randomized to one of three arms: 1) Control (neutral) messages, 2) Traditional health messages, and 3) Counter-marketing messages. In each arm, participants will view four messages developed for their randomly assigned arm and answer questions about the messages and their behavioral intentions.

研究组 & 干预措施
Control (neutral) messages
Participants will view control messages approximately matched to the intervention messages on length, but discussing a neutral topic unrelated to sugary drinks (safe driving). Participants will view a total of 4 messages developed for this arm.
干预措施: Exposure to control (neutral) messages (Behavioral)
Traditional health messages
Participants will view traditional health messages focused on the health consequences of sugar-sweetened beverage consumption, using text adapted from prior sugary drink campaigns. Participants will view a total of 4 messages developed for this arm.
干预措施: Exposure to traditional health messages (Behavioral)
Counter-marketing messages
Participants will view counter-marketing messages about sugary drinks that incorporate principles of effective counter-marketing campaigns, including describing industry manipulation of consumers, appealing to emotions (especially anger), describing health consequences, and criticizing the industry for demographic targeting. Messages include text adapted from prior counter-marketing campaigns. Participants will view a total of 4 messages developed for this arm.
干预措施: Exposure to counter-marketing messages (Behavioral)
结局指标
主要结局
Intentions to consume sugary drinks
时间窗: The survey will take up to 20 minutes
We will assess intentions to consume sugary drinks using 2 items: "In the next week, I plan to drink sugary drinks like sodas, sports drinks, or fruit drinks," and "In the next week, I am likely to drink sugar-sweetened beverages like sodas, sports drinks, or fruit drinks". Response options to both items will use a 5-point Likert scale: the first item's response options will range from "definitely not" (1) to "definitely yes" (5), and the second item's response options will range from "not at all likely" (1) to "extremely likely" (5). We will average responses to the 2 items.
