About this trial
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.

1
Participants' Perceived Intrusiveness of Nudges
A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater perceived intrusiveness.
Time frame
day 12
Participants' Support for Nudges
A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater support for the nudging strategy
