Our goal was to examine how suppression of nontrauma- related thoughts differs between PTSD patients and patients with non-PTSD anxiety disorder compared to a group of matched controls.
Intrusive recollections of aspects of the traumatic event and its sequelae are at the core of the post-traumatic stress disorder (PTSD). People who have suffered a traumatic event may implement some form of avoidance coping strategies in order to deal with the unwanted memories that accompany them. Thought suppression refers to the conscious effort that is made in order NOT to think about a particular thought and is used to regulate affect. The effects of thought suppression on trauma survivors indicates that suppression of trauma related thoughts produces a rebound effect, increasing frequency of negative autobiographical memory recall and may result in the maintenance of PTSD symptoms.
The results show that PTSD patients differed in their performance of purposeful suppression of non-traumarelated thoughts, and spent significantly longer time thinking about the target thought during suppression as compared to the control groups. The duration to disengage attention from any thought content was significantly longer in PTSD patients as compared to the anxiety group and controls.
We suggest that PTSD patients demonstrated a mental control deficient in self-regulatory mechanisms involved in coping with threat.
While PTSD patients used external objects in the room, the control groups used mental contents as distractors. When given suppression instructions, such as distraction thought, all groups demonstrated shorter duration to disengage attention, but the PTSD patients exhibited the significant advantage.
我们的目标是研究与一组匹配的对照组相比,创伤后应激障碍(PTSD)患者和非PTSD焦虑症患者在抑制非创伤相关想法方面有何不同。
对创伤事件及其后遗症的侵入性回忆是创伤后应激障碍(PTSD)的核心。遭受创伤事件的人可能会采取某种形式的回避应对策略,以处理伴随而来的 unwanted 记忆。思想抑制是指为了不去想某个特定想法而做出的有意识努力,用于调节情绪。思想抑制对创伤幸存者的影响表明,抑制与创伤相关的想法会产生反弹效应,增加负面自传体记忆回忆的频率,并可能导致PTSD症状的持续存在。
结果表明,PTSD患者在有目的地抑制非创伤相关想法的表现上存在差异,与对照组相比,在抑制过程中思考目标想法的时间明显更长。与焦虑组和对照组相比,PTSD患者从任何思想内容中转移注意力的持续时间明显更长。
我们认为,PTSD患者在应对威胁时涉及的自我调节机制方面表现出心理控制缺陷。
当PTSD患者使用房间里的外部物体时,对照组使用心理内容作为干扰因素。当给出抑制指令,如分散注意力的想法时,所有组转移注意力的持续时间都较短,但PTSD患者表现出显著优势。
