Impulsivity is a relevant construct for explaining both normal individual differences in personality and more extreme personality disorder, and is often investigated within clinical populations. This study aims to explore the college students' impulsivity patterns and to investigate the association across levels of impulsivity with trauma exposure and PTSD development in a non-clinical population. A one-phase census survey of seven college institutions assessed 2213 students in three metropolitan regions of Northeastern Brazil. All subjects anonymously completed a self-applied protocol consisting of: a socio-demographic questionnaire, Trauma History Questionnaire (THQ), PTSD Checklist (PCL-C), and Barratt Impulsiveness Scale (BIS-11). The median for frequency of trauma exposure was 4 events for people with low and normal impulsivity, and 6 for highly impulsive ones. Individuals with higher impulsivity presented earlier exposition than non-impulsive ones, and worst outcome: 12.4% with PTSD, against 8.4% and 2.3% (normal and low impulsivity). Of the three factors of impulsivity, the Attentional factor conferred the strongest association with PTSD development. Results suggest that impulsivity is also a relevant trait in a non-clinical population and is associated with trauma exposure and PTSD. Strategies to promote mental health in adolescents may be pertinent, especially with the aim of managing impulsivity.
冲动性是解释个体人格差异和更极端的人格障碍的一个相关结构，通常在临床人群中进行研究。本研究旨在探索大学生的冲动模式，并研究在非临床人群中，冲动水平与创伤暴露和 PTSD 发展之间的关联。对巴西东北部三个大都市区的七所大学机构进行了一阶段普查调查，共有 2213 名学生参与。所有受试者匿名完成了一份自我应用的问卷，包括：社会人口学问卷、创伤史问卷（THQ）、创伤后应激障碍检查表（PCL-C）和巴瑞特冲动量表（BIS-11）。低和正常冲动水平的个体创伤暴露频率中位数为 4 次，高冲动水平的个体为 6 次。冲动水平较高的个体比非冲动水平的个体更早暴露，结果更差：12.4%患有 PTSD，而正常和低冲动水平的个体分别为 8.4%和 2.3%。在冲动的三个因素中，注意力因素与 PTSD 发展的相关性最强。研究结果表明，冲动性在非临床人群中也是一个相关特征，与创伤暴露和 PTSD 有关。促进青少年心理健康的策略可能是相关的，特别是旨在管理冲动性。
