This study investigated the relationship of hyperarousal and intrusive symptoms in acute stress disorder (ASD). Civilian trauma survivors with ASD (n = 18) and without ASD (n = 14) completed a hyperventilation provocation test (HVPT) and then completed the Physical Reactions Scale. All participants provided a narrative describing their hyperventilation experience that was audiotaped and independently coded. Individuals with ASD reported greater numbers of intrusive memories and reported greater distress than non-ASD participants. More ASD than non-ASD participants experienced a flashback-type reaction during the hyperventilation. Intrusive symptoms were significantly correlated with elevated arousal following the HVPT. The findings provide evidence that reexperiencing is directly associated with elevated states of arousal.
本研究调查了急性应激障碍（ASD）中过度觉醒与侵入性症状之间的关系。患有ASD的平民创伤幸存者（n = 18）和未患ASD的平民创伤幸存者（n = 14）完成了一项过度换气激发试验（HVPT），然后完成了身体反应量表。所有参与者都提供了一段描述其过度换气经历的叙述，该叙述被录音并进行独立编码。与未患ASD的参与者相比，患有ASD的个体报告了更多的侵入性记忆，并且报告了更大的痛苦。与未患ASD的参与者相比，更多患有ASD的参与者在过度换气期间经历了闪回型反应。侵入性症状与HVPT后觉醒水平升高显著相关。这些发现提供了证据，表明重现与觉醒状态升高直接相关。
