Background
Health-compromising behaviors in adolescents and adults co-occur.
Because motor vehicle crashes are the leading cause of death and disability
for these age groups, understanding the association between risky driving
and other health compromising behaviors is critical.
Methods
We performed a secondary analysis of data from a randomized
controlled trial of an intervention for participants who screened positive
for risky driving and problem drinking. Using baseline data, we examined
relationships among conduct behavior problems before and after age 15,
depressive symptoms, sleep, problem drinking, and risky driving (hostile,
reckless and drinking and driving) in late adolescents ages 18–24
(n= 110) and adults ages 25–44 (n= 202). We
developed a measurement model for the entire sample using confirmatory
factor analysis, which was then specified as a multi-group structural
equation model.
Results
Late adolescents and adults had some similar associations for
pathways through problem drinking to drinking and driving; depression to
reckless driving; and conduct behavior problems after 15 to hostile driving.
Late adolescents, however, had more complex relationships: depressive
symptoms and conduct behavior problems before 15 were associated with more
risky driving behaviors through multiple pathways and males reported more
risky driving.
Conclusions
Risky driving is associated with other health-compromising behaviors
and mental health factors. It is a multidimensional phenomenon more
pronounced in late adolescence than adulthood. In order to promote safe
driving, the findings support the need to consider behaviors that are a
health threat in the late adolescent population during driving training and
licensure.
