Self-affirmation, intentions and alcohol consumption in students: a randomized exploratory trial

Aims: This study tests whether enhancing alcohol risk messages with self-affirmation, the process of focusing on cherished aspects of oneself, increases intentions to reduce alcohol consumption and reduces actual alcohol consumption. It was also examined whether these effects differed by risk status as indicated by standard drinks consumed in an average week.

Methods: Participants (n = 121) were randomly allocated to a self-affirmation or matched control condition before viewing emotive graphic alcohol warning posters in a questionnaire-based study.

Results: There were significant increases in intentions to reduce alcohol consumption in self-affirmed participants, and these effects were stronger in participants with higher behavioural risk. Intentions in turn significantly predicted a reduction in self-reported alcohol consumption.

Conclusions: These findings support the use of self-affirmation to enhance alcohol awareness campaigns, particularly in individuals with high behavioural risk.
