The five factor model of personality and the non-medical use of prescription drugs: Associations in a young adult sample

Personality traits are associated with illicit drug use and substance use disorders. Non-medical use of prescription drugs (NMUPD), the use of medications without a physician's prescription, is increasingly prevalent among young adults. Research suggests that dimensions of the five factor model of personality are predictive of NMUPD, but this has yet to be explored in young adults. The current study examined these relations and found that neuroticism and openness to experience were predictors of NMUPD, while conscientiousness acted as a protective factor. These relations were seen to varying degrees across different drug classes and suggest that personality traits are important to consider in college-aged samples when identifying those most at risk for negative consequences associated with NMUPD.
