Abstract

Objective: This theoretical review proposes a three-phase process model of posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG).

Method: By combining trauma-related theories, emotional regulation theories, social support theories, and empirical study findings to elucidate the mechanisms underlying PTSD and PTG, we then propose our model.

Results: The proposed model highlights the dynamic characteristics of the PTSD and PTG developmental processes as well as their coexistence and places equal emphasis on the roles of cognitive and emotional activities and social support in three distinct dynamic phases of PTSD and PTG. It emphasizes that PTSD and PTG share similar prerequisites but that these two outcomes later diverge and ultimately manifest via three distinct phases. The specific roles of cognitive regulation, emotional regulation, and social support, and the potential theoretical and practical implications of this model, are discussed.

Conclusions: This integrative and dynamic process model has the potential to advance scientific understanding of the mechanisms underlying PTSD and PTG. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

创伤后应激障碍和成长的三阶段过程模型：了解创伤后反应的内在机制。

目的本理论综述提出了创伤后应激障碍（PTSD）和创伤后成长（PTG）的三阶段过程模型：方法：结合创伤相关理论、情绪调节理论、社会支持理论和实证研究结果，阐明创伤后应激障碍和创伤后成长的内在机制，然后提出我们的模型：结果：我们提出的模型突出了创伤后应激障碍和创伤后应激障碍发展过程的动态特征及其共存性，并在创伤后应激障碍和创伤后应激障碍的三个不同动态阶段中对认知、情绪活动和社会支持的作用给予了同等重视。它强调创伤后应激障碍和创伤后应激障碍具有相似的先决条件，但这两种结果后来会出现分化，并最终通过三个不同的阶段表现出来。本文讨论了认知调节、情绪调节和社会支持的具体作用，以及该模型潜在的理论和实践意义：结论：这一综合动态过程模型有可能促进对创伤后应激障碍和创伤后应激障碍潜在机制的科学理解。(PsycInfo Database Record (c) 2024 APA, all rights reserved）。
