title: Self-reported driving behaviors as a function of trait anxiety.
abstract: This study examined self-reported driving behaviors in 120 (Israeli) male drivers as a function of trait anxiety (TA). TA was assessed through the TA scale of the State-Trait Anxiety Inventory. For the analysis of driving behaviors, the present study used the Driver Behavior Questionnaire (DBQ) and adopted previous distinctions between four classes of behaviors within the DBQ: errors, lapses, ordinary violations and aggressive violations. Regression analyses revealed that level of TA had a significant direct positive effect on all dependent variables, suggesting riskier driving behaviors among high-anxious individuals. Significant logarithmic effects for all measures indicate that these aberrant driving behaviors increase more at increasing LTA-, than at increasing HTA-values. Consistent with the general adverse effects of anxiety on performance effectiveness, the present findings as well, are interpreted in the framework of theories which suggest that worries occupy the capacities of working memory, at the expense of the task to be performed. The positive relation between aggressive violations and TA is sought to reflect low levels of emotional adjustment among high-anxious individuals.
