Based on research by Ajzen (2002; doi:10.1111/j.1559-1816.2002.tb00236.x) and Ajzen and Madden (1986; doi:10.1016/0022-1031(86)90045-4), the aim of this study was to explore the relevance of emotions, moral norm (NM) and past behavior (PB) on intention of heavy episodic drinking. A questionnaire was applied to a sample of 119 students from the University of Santiago de Compostela. Results showed that the inclusion of those three variables significantly increased by 7% the amount of explained variance, being NM the largest contributor. These results, along with NM, negative emotions and PB relating not only indirectly, but also directly and significantly with that intention, make these variables relevant for both explaining the intention to perform such risk behavior and informing more efficacious intervention programs.
