Orientation to bodily signals is defined as the way somatic sensations are attended, perceived and interpreted. Research suggests that trauma exposure, particularly the pathological reaction to trauma (i.e., PTSD), is associated with catastrophic and frightful orientation to bodily signals. However, little is known regarding the long-term ramifications of trauma exposure and PTSD for orientation to bodily signals. Less is known regarding which PTSD symptom cluster manifests in the 'somatic route' through which orientation to bodily signals is altered. The current study examined the long-term implications of trauma and PTSD trajectories on orientation to bodily signals. Fifty-nine ex-prisoners of war (ex-POWs) and 44 controls were assessed for PTSD along three time-points (18, 30 and 35 years post-war). Orientation to bodily signals (pain catastrophizing and anxiety sensitivity-physical concerns) was assessed at T3. Participants with a chronic PTSD trajectory had higher pain catastrophizing compared to participants with no PTSD. PTSD symptom severity at T2 and T3 mediated the association between captivity and orientation. Among PTSD symptom clusters, hyperarousal at two time-points and intrusion at three time-point mediated the association between captivity and orientation. These findings allude to the cardinal role of long-term PTSD in the subjective experience of the body following trauma.
对身体信号的定向是指对躯体感觉的关注、感知和解释方式。研究表明,创伤暴露,特别是对创伤的病理性反应(即创伤后应激障碍),与灾难性和可怕的身体信号定向有关。然而,对于创伤暴露和创伤后应激障碍对身体信号定向的长期后果知之甚少。对于哪个创伤后应激障碍症状群通过改变身体信号定向的“躯体途径”表现出来,了解得就更少了。本研究考察了创伤和创伤后应激障碍轨迹对身体信号定向的长期影响。对 59 名前战俘(前战俘)和 44 名对照者在三个时间点(战后 18、30 和 35 年)进行了创伤后应激障碍评估。在 T3 时评估了对身体信号的定向(疼痛灾难化和焦虑敏感-身体关注)。与无创伤后应激障碍的参与者相比,具有慢性创伤后应激障碍轨迹的参与者的疼痛灾难化程度更高。T2 和 T3 的创伤后应激障碍症状严重程度在被俘与定向之间的关联中起中介作用。在创伤后应激障碍症状群中,两个时间点的过度唤醒和三个时间点的入侵在被俘与定向之间的关联中起中介作用。这些发现暗示了长期创伤后应激障碍在创伤后对身体主观体验中的主要作用。
