Overview
The primary objective of this study was to examine whether three nudging strategies influence beverage consumption behavior among Chinese university students. These interventions included health warning messages, hedonic labeling, and a combination of health warning and hedonic labeling. A between-subjects experimental design with a single factor was employed to assess the effects of these strategies on students' choices between sugar-sweetened and sugar-free beverages, thereby evaluating their effectiveness in promoting healthier beverage selections.
Detailed description
As the prevalence of overweight, obesity, and chronic diseases continues to escalate, excessive consumption of sugar-sweetened beverages (SSBs) has emerged as a growing public health concern globally. One approach to reducing beverage intake while conserving resources is the utilization of nudge strategies. Nudge strategies, characterized by their low cost and ease of implementation, facilitate individuals in making more accurate and beneficial choices in a predictable manner, through subtle interventions that do not prohibit any options or significantly alter incentives. This study will be conducted in a classroom setting, where participants will be randomly assigned to one of four groups: a no-nudge control group, a health warning group, a hedonic labeling group, and a combined health warning plus hedonic labeling group.
Interventions
- Behavioral choice architecture
Showing the various harms that can come from long-term excessive consumption of sugary beverages on the platform. - Behavioral choice architecture
The platform shows the hedonic information about sugar-free beverages. - Behavioral choice architecture
The platform shows both hedonic information about sugar-free beverages and information on the various harms of long-term excessive sugary beverage consumption.
Primary outcome measures
- The proportion (or likelihood) of selecting sugar-free beverages [Time frame: day 1]
Secondary outcome measures (3)
- Participants' Perceived Intrusiveness of Nudges [Time frame: day 1]
- Participants' Support for Nudges [Time frame: day 1]
- Participants' Perceived effectiveness of Nudges [Time frame: day 1]
