Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does a label containing a cancer message have a larger impact on knowledge, behavior, intentions, risk perception, emotional response, product appeal and policy support compared to a responsibility label?
* Does the positioning of the label (front vs. back) on the alcohol container affect these outcomes?
Researchers will compare the impact of cancer message labels vs. responsibility labels and front vs. back positioning to see if there are differences in the primary outcome (knowledge of alcohol causing cancer) and secondary outcomes (behavior, intentions, risk perception, emotional response, and policy support).
Additionally, the study will provide insight in whether there is a testing effect of primary outcome pre-measurement by exposing only half of the sample to baseline question on knowledge of alcohol related harms.
Participants will:
* Be recruited in front of selected supermarkets in Barcelona after purchasing alcohol for their own consumption.
* Complete a baseline questionnaire.
* Receive a sticker containing a randomly assigned health message that will be applied to every alcohol beverage they have purchased.
* Receive an invitation to complete two follow-up surveys, one a week and one a month after the intervention.
