Peritraumatic dissociation predicts posttraumatic stress disorder symptoms via dysfunctional trauma-related memory among war-affected children



Peritraumatic dissociation predicts posttraumatic stress disorder symptoms via dysfunctional trauma-related memory among war-affected children



European Journal of Psychotraumatology 8(Sup3): 1375828



背景:在成人中有强证据支持围创伤期分离(PD)预测创伤后应激障碍(PTSD),但是在儿童中的证据有限。记忆功能受损或许可以解释PD和PTSD的关联,但还未被实证验证过。 目标:我们想要验证更高PD和更多PTSD症状关联的假设,其中有些关联路径可能被对创伤事件的杂乱的和非语言性记忆中介。 方法:样本包括了197名住在加沙地带的巴勒斯坦儿童(10–12岁),在2008年9月的战争后参加研究。用围创伤期分离体验问卷(Peritraumatic Dissociative Experiences Questionnaire)测量战后三个月的PD,创伤记忆质量问卷Trauma Memory Quality Questionnaire)测量创伤相关记忆,修订后儿童版事件影响量表(Children’s Revised Impact of Event Scale)测量6个月后的PTSD。并使用一个清单量表评测对战争创伤的暴露。使用结构方程模型来考察控制战争创伤事件后PD到PTSS直接和间接的路径。 结果:结构方程模型的结果显示更多地自我报告PD预测9个月后更高水平的PTSS,这种关联中的大部分(并非全部)被创伤相关记忆的质量中介了。 结论:本研究提供了实证证据支持在受战争影响的儿童中,经历创伤事件时更多PD和几个月之后更高水平的PTSD症状有关联,在控制了个体的战争创伤暴露程度之后也如此。进一步地,本研究支持了分离症状在创伤事件中的有害影响可能是因为异常记忆通常表现出的混乱和难以用语言表达和缺乏连贯性。未来需要在更大样本中使用更多测量点对这些假设进行进一步验证。.
