ABSTRACT

Several theories exist regarding the role of memory in the development of PTSD. The metacognitive model of PTSD contends beliefs about trauma memory are pivotal in the development and maintenance of PTSD. The Beliefs About Memory Questionnaire (BAMQ) was developed to measure metacognitive beliefs about trauma memory. This study aimed to test the psychometric properties of the BAMQ and its relationship to PTSD in a community sample of 674 adults exposed to the 2010–2011 Canterbury earthquakes and Queensland floods. Participants completed a series of online, self-report questionnaires between October and December 2012, exploring thinking and memory processes related to their experience of a natural disaster. Factor analysis validated the two-factor, positive and negative structure of the BAMQ. Convergent, concurrent, and discriminant validity was established through positive relationships with relevant metacognitive beliefs, thought control variables, and risk factors related to PTSD. Logistic regression revealed scores on the BAMQ predicted clinically significant symptoms of PTSD. The psychometric properties of the BAMQ suggest the instrument is a valuable addition to the assessment of metacognitive beliefs about trauma memory, and the utility of the BAMQ in the prediction of clinically significant symptoms of PTSD.

摘要

关于记忆在 PTSD 发展中的作用存在几种理论。PTSD 的元认知模型认为关于创伤记忆的信念在 PTSD 的发展和维持中至关重要。关于记忆问卷的信念（BAMQ）被开发用于测量关于创伤记忆的元认知信念。本研究旨在测试 BAMQ 的心理测量特性及其与 PTSD 的关系，该社区样本包含 674 名暴露于 2010-2011 年坎特伯雷地震和昆士兰洪水的成年人。参与者在 2012 年 10 月至 12 月期间完成了一系列在线自我报告问卷，探索与自然灾害经历相关的思维和记忆过程。因子分析验证了 BAMQ 的正负结构两因素。收敛，并发，判别效度是通过与相关元认知信念、思想控制变量和与 PTSD 相关的风险因素的积极关系建立的。Logistic 回归显示 BAMQ 的分数预测了 PTSD 的临床显着症状。BAMQ 的心理测量特性表明，该工具是评估有关创伤记忆的元认知信念的宝贵补充，以及 BAMQ 在预测 PTSD 临床显着症状中的效用。
