Discriminant Profile of Young Adulthood Driving Behavior among Brazilian Drivers.Discriminant Profile of Young Adulthood Driving Behavior among Brazilian Drivers.

The aim of this article was to describe the driving behavior profile of drivers aged 18 to 25 years old.

Four hundred young adults were interviewed, 320 (80%) of them male and 80 (20%) female.

Cluster analysis identified a group characterized by sensation-seeking behavior (Cluster 1), a group that did not show any risky driving behavior (Cluster 2), and a group engaged in transgressive behavior and driving under the influence of alcohol and/or drugs (Cluster 3).

Discriminant analysis classified successfully and correctly 81.3% of the young adults into their original profiles. Function 1 distinguished cluster 1 from clusters 2 and 3, on the basis of the following factors: higher frequency of alcohol consumption, intrusive behavior, and motorcycle riding, as well as younger age, more aggressive behavior, and lower education level. Function 2 distinguished cluster 3 from cluster 1 and 2, especially as to higher amounts of alcohol consumption, higher frequency of marijuana use and delinquent behavior, larger number of traffic tickets and motor vehicle accidents, higher paternal education level, which were the variables with discriminant values above .20.

Characteristics of vulnerability were identified, especially those related to alcohol consumption, drug use, and externalizing issues.
