Posttraumatic stress disorder (PTSD) has been linked to risky sexual behavior (RSB). However, little is known regarding the role of impulsivity in this relation among college students. The present study examined the moderating role of impulsivity dispositions on the relation between PTSD symptoms and past-year RSB in a sample of 221 trauma-exposed undergraduate students (77.4% female). Two separate negative binomial regression models examined each impulsivity disposition's unique moderating effect on the association between PTSD symptoms and high risk/casual sex. In the high risk model, significant interactions were found for the urgency dispositions, (lack of) premeditation and (lack of) perseverance, though the pattern of these relations differed across these dispositions. Only positive main effects for negative urgency and (lack of) premeditation emerged in the casual sex model. The present study expands on the limited literature on the role of impulsivity in the relation between PTSD and RSB in trauma-exposed college students.
创伤后应激障碍（PTSD）与危险性行为（RSB）有关。然而，人们对于大学生中冲动性在这种关系中的作用知之甚少。本研究在 221 名创伤后大学生样本中，检验了冲动特质在 PTSD 症状与过去一年的 RSB 之间关系中的调节作用（77.4%为女性）。两个单独的负二项式回归模型分别检查了每种冲动特质对 PTSD 症状与高危/随意性行为之间关联的独特调节作用。在高危模型中，发现了冲动特质（缺乏）的显著交互作用，包括冲动性、缺乏深思熟虑和缺乏坚持性，但这些关系的模式在这些特质中有所不同。只有负性冲动和缺乏深思熟虑在随意性行为模型中出现了积极的主要效应。本研究扩展了关于冲动性在创伤后大学生 PTSD 与 RSB 关系中的作用的有限文献。
