Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to evaluate whether alcohol warnings about different topics elicit higher perceived message effectiveness than control messages. The secondary objective is to evaluate whether alcohol warnings about different topics elicit higher reactance than control messages.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will complete a within-subjects online randomized experiment in which they will view and rate messages on the risk of alcohol consumption. Participants will view and rate 12 messages total: 10 warning messages and 2 control messages. They will rate each message on perceived message effectiveness (primary outcome) and message reactance (secondary outcome). The 10 warning messages will be about 5 different warning topics (i.e., 2 messages per topic) and the 2 control messages will be about 1 control topic (2 messages per topic). In this within-subjects experiment, the survey will present the topics in random order and the messages within each topic in random order.
