Traditional models of posttraumatic stress disorder (PTSD) claim that the high emotional intensity of traumatic events leads to deficits in the voluntary access of traumatic memories. This may result in disorganized narratives, with a high sense of emotional and sensory reliving. Alternatively, the basic mechanisms view suggests that high arousal leads to more available involuntary and voluntary memories. Traumatic narratives would not be impaired; indeed, they would be immersive and rich in detail. To test this perspective, this study compared the trauma narratives of 50 battered women (trauma-exposed group) with narratives about positive experiences and narratives of 50 nonexposed women (controls), and analyzed the relationship between trauma narrative aspects and the severity of PTSD. Results showed that trauma narratives were detailed, oriented, and coherent. Affective process words and emotional tone were related to trauma centrality and anxiety during disclosure, and predicted the severity of PTSD (R = .26). These variables, together with the use of present tense verbs, accounted for a significant variance in intrusions (R = .34). As hypothesized, narrative aspects related to a sense of reliving and narrative immersion were better predictors of PTSD than aspects reflecting impaired access to voluntary traumatic memories.
创伤后应激障碍(PTSD)的传统模型认为,创伤事件的高情绪强度会导致对创伤记忆的自愿提取出现缺陷。这可能会导致叙述杂乱无章,伴有强烈的情感和感官重现感。另外,基本机制观点认为,高度唤醒会导致更多的非自愿和自愿记忆。创伤叙述不会受损;事实上,它们会身临其境且细节丰富。为了验证这一观点,本研究将50名受虐妇女(创伤暴露组)的创伤叙述与关于积极经历的叙述以及50名未暴露妇女(对照组)的叙述进行了比较,并分析了创伤叙述方面与PTSD严重程度之间的关系。结果表明,创伤叙述详细、有导向且连贯。情感过程词和情感基调与披露过程中的创伤核心性和焦虑有关,并能预测PTSD的严重程度(R = 0.26)。这些变量,连同现在时态动词的使用,在侵入方面解释了显著的方差(R = 0.34)。正如所假设的,与重现感和叙述沉浸感相关的叙述方面比反映自愿创伤记忆提取受损的方面更能预测PTSD。
