Summary
This study looked at whether showing health warning messages in a mobile app where people buy alcohol affects their purchasing. Over 11,700 adults in Sweden took part. One group saw rotating health warnings, while the other saw standard messages. The researchers tracked purchases and surveyed participants to see if the warnings changed knowledge, risk perception, or buying behavior.
