Abstract

Objectives: Cognitive processing therapy (CPT) is an evidence-based psychotherapy for posttraumatic stress disorder (PTSD); however, little is known about how interrelationships between PTSD symptoms change over the course of treatment. The current study examined baseline, midtreatment, and posttreatment PTSD symptom networks during CPT for PTSD.

Method: Adults with PTSD (n = 107) received 12 sessions of CPT as part of a randomized trial. Self-reported PTSD symptoms were assessed at pretreatment, midtreatment, and posttreatment, and network analysis was used to examine the interrelationships between symptoms at these three timepoints. Linear regression was conducted to examine whether any baseline symptoms or midpoint symptoms predicted overall treatment change.

Results: In the baseline PTSD network, feelings of detachment and feeling upset at reminders of the trauma were central to the symptom network. These symptoms were no longer central at midtreatment, possibly suggesting that CPT quickly reduces the importance of these symptoms. These findings were consistent with regression results that, after accounting for multiple comparisons, high baseline scores of feeling upset at trauma reminders predicted later treatment change. At the conclusion of treatment, strong negative emotions were the most central symptom and may be most important in maintaining or lowering other PTSD symptoms at the conclusion of treatment.

Conclusions: Though replication is necessary, these findings offer insights into identifying which symptoms may be most predictive of treatment outcomes and the course by which CPT reduces PTSD symptoms. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

认知加工治疗过程中PTSD症状网络的检查。
目的:认知加工疗法(CPT)是一种基于证据的创伤后应激障碍(PTSD)心理治疗方法;然而,人们对创伤后应激障碍症状之间的相互关系如何在治疗过程中发生变化知之甚少。目前的研究检查了CPT治疗PTSD的基线、治疗中期和治疗后PTSD症状网络。方法:作为随机试验的一部分,患有PTSD的成年人(n=107)接受了12次CPT治疗。自我报告的PTSD症状在治疗前、治疗中和治疗后进行评估,并使用网络分析来检查这三个时间点症状之间的相互关系。进行线性回归以检查是否有任何基线症状或中点症状可以预测总体治疗变化。结果:在基线PTSD网络中,超然感和对创伤的提醒感到沮丧是症状网络的核心。这些症状在治疗中期不再是核心,这可能表明CPT很快降低了这些症状的重要性。这些发现与回归结果一致,即在考虑了多重比较后,对创伤提醒感到不安的高基线分数预测了以后的治疗变化。在治疗结束时,强烈的负面情绪是最核心的症状,在治疗结束后可能对维持或降低其他创伤后应激障碍症状最重要。结论:尽管复制是必要的,但这些发现为确定哪些症状可能最能预测治疗结果以及CPT减轻PTSD症状的过程提供了见解。(PsycInfo数据库记录(c)2023 APA,保留所有权利)。
