METHODS: Thirty-four participants completed up to 10 ecological momentary assessment surveys before, during and after 63 AFL games (n = 437 completed surveys). Surveys collected data about their drinking, and their social and environmental milieu (e.g., location, company). Binary logistic regression analyses clustered by participant identified which game-day characteristics were associated with higher odds of risky single occasion drinking. Significant differences between pre-game, during-game and post-game drinking on social and environmental factors were explored using pairwise comparisons.

RESULTS: Risky single occasion drinking was more likely when games began in the early-afternoon (1-3 pm) than late-afternoon (3-6 pm), when participants watched the game at a stadium or pub compared to home, and when participants watched the game with friends compared to family. Pre-drinking was more likely before night games and post-drinking was more likely after day games. Drinking during the game was heavier when watching the game at a pub and when watching with a combined group of friends and family.
