Intrusive mental experiences occur within posttraumatic stress disorder (PTSD) and some psychotic disorders. Similarities in the phenomenology and content in the intrusions of both disorders have been noted. Currently there is little understanding of any common etiology in terms of information-processing styles. This study investigated predictors of analogue posttraumatic intrusive cognitions within a nonclinical sample, including schizotypy, dissociation, and trauma history. Forty-two participants watched a trauma video and recorded trauma-related intrusions occurring for 1 week. More reported intrusive experiences were associated with high positive symptom schizotypy. Our findings are discussed in relation to the possible role of trauma-related intrusions within psychotic disorders.
侵入性心理体验出现在创伤后应激障碍（PTSD）和一些精神障碍中。人们已经注意到这两种障碍的侵入现象在现象学和内容上存在相似之处。目前，对于信息处理方式方面的任何共同病因了解甚少。本研究调查了非临床样本中类似创伤后侵入性认知的预测因素，包括分裂型人格特质、解离和创伤史。42名参与者观看了一段创伤视频，并记录了为期1周内出现的与创伤相关的侵入情况。更多报告的侵入性体验与高阳性症状分裂型人格特质相关。我们将结合创伤相关侵入在精神障碍中可能发挥的作用来讨论我们的研究结果。
