Adapting the biodispositional model of personality to alcohol use, we could expect that personality traits should be related to distal consequences of drinking by influencing more proximate cognitive and behavioural variables. To test this hypothesis we assessed alcohol consumption patterns with a Graduated-Frequency survey. We also evaluated the consequences of alcohol use (RAPI), and personality traits (ZKA-PQ). The sample was formed by 657 young adults, with a mean age of 22.86 (Sd=3,56) (47% females and 55% males). We performed different regression and structural equation analyses. We found a mediational model that fitted the data. The 46% of the alcohol use problems’ variance was explained. Sensation Seeking and Aggression were significantly related to this outcome. However, the association was not direct but through the prediction of a high-risk alcohol consumption pattern. The results were discussed in base of the theoretical constructs that support the alternative five personality model.
