背景：创伤后应激障碍（PTSD）涉及可破坏认知功能的衰弱症状。情绪Stroop常被用来检查PTSD对注意力控制的影响，但还没有发表的研究将其用于阿富汗和伊拉克战争退伍军人，只有一项先前的研究比较了对创伤相关词汇的习惯化。方法：我们对30名患有PTSD的退伍军人，30名军事对照，30个民用控制器Stroop词的类型包括战斗，匹配中性，中性，积极和Negative.Results：相比，对照组，退伍军人与PTSD不成比例地慢，在应对战斗的话。他们也更慢，整体准确性较低，相对于中性，没有表现出对消极或积极词的干扰，并表现出延迟但成功习惯于战斗词的趋势。更高的PCL和BDI分数也与较大的干扰effects.Conclusions：由于其特异性在检测注意力偏差创伤相关的话，情绪Stroop任务可以作为一个有用的前和后任务与PTSD患者的干预研究。
Background: Post-traumatic stress disorder (PTSD) involves debilitating symptoms that can disrupt cognitive functioning. The emotional Stroop has been commonly used to examine the impact of PTSD on attentional control, but no published study has yet used it with Afghanistan and Iraq war veterans, and only one previous study has compared groups on habituation to trauma-related words.Methods: We administered the emotional Stroop, the Beck Depression Inventory (BDI), and the PTSD Checklist (PCL) to 30 veterans with PTSD, 30 military controls, and 30 civilian controls. Stroop word types included Combat, Matched-neutral, Neutral, Positive and Negative.Results: Compared to controls, veterans with PTSD were disproportionately slower in responding to Combat words. They were also slower and less accurate overall, did not show interference on Negative or Positive words relative to Neutral, and showed a trend for delayed but successful habituation to Combat words. Higher PCL and BDI scores also correlated with larger interference effects.Conclusions: Because of its specificity in detecting attentional biases to trauma-related words, the emotional Stroop task may serve as a useful pre- and post task with intervention studies of PTSD patients.
