Summary
Brief summary
The trial aims to assess if designated driver programs may increase alcohol consumption intentions of community football club members. Participants will be randomised to receive a hypothetical scenario describing a post match celabration, or an identical scenario which also indicates that participants would have access to a designated driver to transport the participant home following the celebration. Participants will then be asked to indicate the quantity of alcohol they would intend to consume given this scenario.
