Impulsivity and sensation-seeking personality traits as predictors of substance use among university students in Jordan

The purpose of the current study was to investigate the relationship between substance use and impulsivity and sensation-seeking personality traits among 655 university students using a cross-sectional, descriptive, correlational design. A signifi cant correlation was found between students’ impulsivity level scores and frequency of substance use (r = 0.11, p \u3c 0.05). A positive correlation was found between frequency of substance use and sensation-seeking levels (r = 0.2, p \u3c 0.05), as well as impulsivity levels (r = 0.31, p \u3c 0.01). Multiple linear regression analysis showed that the two predictors model was able to account for 12.4% of variation in substance use.
