Despite high levels of traffic-related mortality, injury, and impairment among former service members, measures validated to assess problematic driving in this population remain limited. The current study examined characteristics of the Driving Behavior Survey (DBS) in male veterans (76.3% White; age: M = 56.4, SD = 12.3) meeting criteria for PTSD. Confirmatory factor analyses indicated acceptable fit of a 3-factor model specifying dimensions of anxiety-based performance deficits, exaggerated safety/caution, and hostile/aggressive driving behavior. Concurrent associations with indices of anxiety, depression, trauma history, and clinician-rated PTSD were consistent with small (r = .10-.29) to medium (r = .30-.49) effects. Discriminative validity was noted through elevations in performance deficit (d = .26), safety/caution (d = .50), and hostile/aggressive (d = .39) scales relative to published data from student drivers. Scores comparable to civilian motorists with accident-related PTSD help to qualify the severity of problematic driving behavior in trauma-exposed veterans.
尽管前军人的交通相关死亡率、伤害率和失能率较高，但用于评估该人群驾驶问题的经过验证的措施仍然有限。本研究检查了符合 PTSD 标准的男性退伍军人（76.3%为白人；年龄：M=56.4，SD=12.3）的驾驶行为调查（DBS）的特征。验证性因子分析表明，指定焦虑为基础的表现缺陷、夸大的安全/谨慎和敌对/攻击性驾驶行为维度的 3 因素模型具有可接受的拟合度。与焦虑、抑郁、创伤史和临床医生评定 PTSD 的指数的同时关联与小（r=0.10-0.29）至中等（r=0.30-0.49）效应一致。通过与从学生驾驶员那里获得的已发表数据相比，在表现缺陷（d=0.26）、安全/谨慎（d=0.50）和敌对/攻击性（d=0.39）量表上的得分升高，注意到了判别效度。与因事故导致 PTSD 的民用驾驶员相比，得分相当有助于确定创伤暴露的退伍军人中驾驶问题行为的严重程度。
