OBJECTIVE
Posttraumatic stress disorder (PTSD) has a well-established theoretical and empirical relation with impulsivity. Prior research has not used a multidimensional approach for measuring both PTSD and impulsivity constructs when assessing their relationship.
METHOD
The current study assessed the unique relationship of impulsivity facets on PTSD symptom clusters among a nonclinical sample of 412 trauma-exposed adults.
RESULTS
Linear regression analyses revealed that impulsivity facets best accounted for PTSD's arousal symptoms. The negative urgency facet of impulsivity was most predictive, because it was associated with all of PTSD's symptom clusters. Sensation seeking did not predict PTSD's intrusion symptoms, but did predict the other symptom clusters of PTSD. Lack of perseverance only predicted intrusion symptoms, while lack of premeditation only predicted PTSD's mood/cognition symptoms.
CONCLUSIONS
Results extend theoretical and empirical research on the impulsivity-PTSD relationship, suggesting that impulsivity facets may serve as both risk and protective factors for PTSD symptoms. (PsycINFO Database Record
目的
创伤后应激障碍（PTSD）与冲动性之间存在既定的理论和实证关系。先前的研究在评估创伤后应激障碍和冲动性结构之间的关系时，未采用多维方法来测量这两者。
方法
本研究评估了412名有创伤经历的成年人非临床样本中，冲动性各方面与创伤后应激障碍症状群之间的独特关系。
结果
线性回归分析显示，冲动性各方面最能解释创伤后应激障碍的唤醒症状。冲动性的消极紧迫性方面预测性最强，因为它与创伤后应激障碍的所有症状群相关。冒险寻求不能预测创伤后应激障碍的闯入症状，但能预测创伤后应激障碍的其他症状群。缺乏毅力仅能预测闯入症状，而缺乏预谋仅能预测创伤后应激障碍的情绪/认知症状。
结论
研究结果扩展了关于冲动性与创伤后应激障碍关系的理论和实证研究，表明冲动性各方面可能既是创伤后应激障碍症状的风险因素，也是保护因素。（《心理学文摘数据库记录》
