背景：在解释创伤后应激障碍的理论中，世界假设的变化是一个基本概念。本研究的目的是为了更好地了解如何在世界假设的变化与生活质量和创伤后应激症状后的自然灾害。方法：一项纵向研究574挪威成年人谁在2004年东南亚海啸幸存下来进行。多层次分析，以确定哪些因素在海啸后6个月预测的生活质量和创伤后应激症状两年后的海啸。结果：良好的生活质量和创伤后应激症状呈负相关。然而，这些结果的预测因素存在很大的差异，女性比男性有更高的生活质量和更多的创伤后压力。海啸暴露程度与生活质量之间的联系似乎是由创伤后应激介导的。在“世界是公正的”的假设中，负面的感知变化与生活质量和创伤后应激的不良后果有关。积极的感知变化的假设“生活是有意义的”和“感觉我是一个有价值的人”与更高水平的生活质量，但不与创伤后stress.Conclusions：生活质量和创伤后应激症状表现出差异，其病因。世界假设可能不像一些认知理论中所假设的那样与创伤后应激反应有具体的关系。
Background: Changes in world assumptions are a fundamental concept within theories that explain posttraumatic stress disorder. The objective of the present study was to gain a greater understanding of how changes in world assumptions are related to quality of life and posttraumatic stress symptoms after a natural disaster.Methods: A longitudinal study of 574 Norwegian adults who survived the Southeast Asian tsunami in 2004 was undertaken. Multilevel analyses were used to identify which factors at six months post-tsunami predicted quality of life and posttraumatic stress symptoms two years post-tsunami.Results: Good quality of life and posttraumatic stress symptoms were negatively related. However, major differences in the predictors of these outcomes were found. Females reported significantly higher quality of life and more posttraumatic stress than men. The association between level of exposure to the tsunami and quality of life seemed to be mediated by posttraumatic stress. Negative perceived changes in the assumption "the world is just" were related to adverse outcome in both quality of life and posttraumatic stress. Positive perceived changes in the assumptions "life is meaningful" and "feeling that I am a valuable human" were associated with higher levels of quality of life but not with posttraumatic stress.Conclusions: Quality of life and posttraumatic stress symptoms demonstrate differences in their etiology. World assumptions may be less specifically related to posttraumatic stress than has been postulated in some cognitive theories.
