Abstract

The consumption of caffeine has become a growing concern, partially because of the withdrawal properties of the drug. The current study examined personality correlates of caffeine consumption and dependence in 60 university students. Self-report and behavioral measures of sensation seeking, impulsivity, and risk taking were administered to 2 groups, identified as caffeine dependent-high consuming or caffeine nondependent-low consuming. Scores on self-report measures of sensation seeking and impulsivity were related to group status, and only sensation seeking evidenced a significant relationship with group status when both variables were considered in a regression analysis. Implications of these findings and future directions are discussed.
