NCT06596564

Brief Summary

The primary objective of this study was to examine whether four nudging strategies influence beverage consumption behavior among Chinese university students. These interventions included sugar content information, health warning messages, hedonic labeling, and default option nudge. 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.

Control

NO INTERVENTION

In this group, no nudge interventions were implemented, only data were collected.

choice architecture (Sugar Content Information)

EXPERIMENTAL

Students are exposed to information about the sugar content of sugar-sweetened beverages on the Questionnaire Star platform to "nudge" students towards healthier choices

Behavioral: choice architecture

choice architecture (health warning Information)

EXPERIMENTAL

The platform presented information outlining the potential health risks associated with excessive consumption of sugar-sweetened beverages.

Behavioral: choice architecture

choice architecture (hedonic label Information)

EXPERIMENTAL

Students are exposed to hedonic information about sugar-free beverages on the Wenjuanxing platform to "nudge" students towards healthier choices

Behavioral: choice architecture

choice architecture (default option)

EXPERIMENTAL

Setting sugar-free options as the default to "nudge" students towards healthier choices.

Behavioral: choice architecture

Interventions

Display the sugar content of the drink on the platform.
