Aggressive drivers data
Data about participants from psychological tests and non-biochemical measurements were acquired from the Department of Psychology, Faculty of Arts, Faculty of Philosophy of Palacký University Olomouc, Czech Republic. The participants were recruited for the study by advertisements on the relevant social networks groups and by leaflets hanged out in the University or public premises (libraries, refectory etc.). Inventory of traffic-relevant personality characteristics (shortened version, TVP), Sensation Seeking Scale form, and Buss a Durkee aggression inventory were performed for psychological testing. Salivary testosterone and cortisol were measured from saliva obtained at 8:00am for each participant. Obtained data were transformed into data matrix, where only relevant data were kept. One participant was excluded from the study, due to corticosteroid medication. Overall, analysis was performed using 149 participants. Binomial models were employed with five dependent variables, which we assumed to reflect driver’s tendency to aggressive behaviour: 1. Caused an accident, 2. Driving license taken away, 3. Court trial, 4. Intoxicated driving, 5. Sporty self-report.
