以往关于创伤后应激障碍（PTSD）易感性的研究一直受到缺乏在创伤前测量个体差异的前瞻性研究的限制。本研究采用全前瞻性设计调查模拟创伤后侵入性认知的预测因素。非患者参与者在观看关于创伤性火灾的电影之前完成了一系列预测指标。电影诱发的消极情绪变化也被评估。随后的入侵在实验期间和接下来的7天内都被测量。假设的预测因素有：神经质、特质焦虑、外向性、抑郁、压抑不愉快想法的一般倾向、关于火灾“有危险”的信念、心理意象、自我评估的入侵倾向和负面情绪变化。结果表明，电影诱发的负面情绪、思想抑制倾向、火灾易感性信念和自评侵入性认知倾向的增加可以预测侵入性认知。研究结果与有关PTSD的思维抑制和认知过程的文献进行了讨论。
Previous research on vulnerability to Post-Traumatic Stress Disorder (PTSD) has been restricted by the absence of prospective studies that measure individual differences prior to traumatization. This study investigated the predictors of analogue post-traumatic intrusive cognitions using a fully prospective design. Non-patient participants completed a range of predictor measures before being exposed to a film about a traumatic fire. Film-induced changes in negative mood were also assessed. Subsequent intrusions were measured both within the experimental session and for a further seven days. The hypothesized predictors were: neuroticism, trait anxiety, extraversion, depression, a general tendency to suppress unpleasant thoughts, beliefs about being “at risk” from fire, mental imagery, self-rated proneness to intrusions and negative mood changes. The results showed that intrusions were predicted by film-induced increases in negative mood, thought suppression tendencies, beliefs about vulnerability to fire and self-rated proneness to intrusive cognitions. The findings are discussed in relation to the literature on thought suppression and cognitive processes in PTSD.
