INTRODUCTION: Alcohol advertising is prevalent on social media. The current study sought to identify effective message types to pair with social media alcohol ads to minimise purchase intentions associated with exposure.
METHODS: A 6 (within) × 5 (between) randomised controlled experiment was conducted with n = 723 US participants. Participants viewed six unique social media alcohol ads and were randomised to view one of four message types (i.e. pro-drinking comments, anti-drinking comments, industry responsibility messages and health warning labels) associated with the ads or the control (i.e. no messages). Purchase intentions were measured after each ad exposure. Significant main and interactive effects were determined by two-level, random intercept hierarchical linear models.
RESULTS: Purchase intentions were significantly lower among participants who viewed anti-drinking comments relative to the control (P = 0.022) and warning labels (P = 0.016). Purchase intentions were significantly greater among participants who viewed pro-drinking comments and had a family history of alcohol use (P = 0.032) and among those who viewed warning labels and were previously exposed to alcohol depictions through family and friends' social media posts (P = 0.033).
DISCUSSION AND CONCLUSIONS: Anti-drinking messages, written by social media users, may be effective at reducing alcohol purchase intentions when posted as social media comments. Current industry responsibility messages had no effect, and caution may be needed if warning labels are applied to ads in this medium.
