In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participants rated movie clips in a 30-minute ad libitum drinking session in dyads, and their alcohol consumption was measured. Finally, measures of alcohol risk perception and attitudes were completed. Results show that generating antialcohol arguments - regardless of whether they are posted online - is effective in increasing alcohol risk perception but does not affect immediate alcohol consumption.
