The current study examines four personality traits, impulsivity, sensation seeking, hopelessness, and anxiety sensitivity, as predictive factors of pregaming as well as the relationship with heavy episodic drinking and alcohol related consequences. It was hypothesized that sensation seeking, impulsivity, hopelessness, and anxiety sensitivity will be related to higher levels of pregaming, and that pregaming would be associated with higher levels of heavy episodic drinking and increased alcohol related consequences. The sample consisted of 196 undergraduate students (84.7% female), with an average age of 22. Impulsivity, sensation seeking, hopelessness, and anxiety sensitivity were not found to be predictors of pregaming behaviour. Pregaming was found to predict higher levels of heavy episodic drinking, as well as increased alcohol related consequences. The results from this study have the potential to inform intervention strategies tailored to drinking behaviour at the pregaming level in order to reduce heavy episodic drinking and alcohol related consequences.
