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.

本研究的心理测试与非生化检测数据采集自捷克共和国奥洛穆茨帕拉茨基大学（Palacký University Olomouc）文学院与哲学院心理学系。研究受试者通过相关社交网络群组广告，以及在大学及公共场所（图书馆、食堂等）张贴传单的方式招募而来。本次心理测试涵盖三项内容：交通相关人格特征量表简版（Traffic-relevant Personality Inventory, TVP）、感觉寻求量表（Sensation Seeking Scale）以及布斯-达基攻击量表（Buss-Durkee Aggression Inventory）。所有受试者于上午8时采集唾液样本，用于检测唾液睾酮与皮质醇水平。采集所得数据经整理为数据矩阵，仅保留有效相关数据。因1名受试者正在服用皮质类固醇类药物，故将其排除出本研究。最终纳入149名受试者开展数据分析。本研究采用二项模型对5项因变量进行分析，我们假定这5项指标可反映驾驶员的攻击性行为倾向：1. 引发交通事故；2. 驾驶证被吊销；3. 接受法庭审判；4. 醉酒驾驶；5. 运动型驾驶自我报告。
