Risky driving among young Australian drivers II: Co-occurrence with other problem behaviours

This study examined the co-occurrence of risky driving with a range of externalising and internalising problems among 1055 young Australian drivers participating in an ongoing, 23-year longitudinal study. This issue was examined by: (1) investigating the co-occurrence of risky driving and other problem outcomes at 19–20 years; (2) exploring the rate of single and multiple problems among high, moderate and low young risky drivers and (3) investigating connections between risky driving in early adulthood and adolescent problem behaviours. Concurrent and longitudinal associations between risky driving and both substance use (alcohol, cigarette and marijuana use, binge drinking) and antisocial behaviour were found. However, risky driving generally appeared unrelated to internalising problems (depression, anxiety) and early sexual activity. Overall, young risky drivers varied considerably in the number and types of problem behaviours exhibited, although the great majority (70%) had displayed at least one other type of problem behaviour.
