Perseverative Cognition Hypothesis Testing Effects

项目摘要

Within the stress literature, an important string of recent studies have revealed that, even in instances where a physical stressor is absent, the cognitive representation alone can be enough to induce a physiological stress response, which, when prolonged, has been shown to increase the likelihood of stress-related diseases. This cognitive tendency, coined the preservative cognition hypothesis, has now been subject to much academic attention resulting in recent meta-analyses which report it as a significant influence on somatic health and wellbeing. However, despite this, few studies have attempted to combat the negative effects of perseveration on health outcomes and none thus far have attempted to develop an intervention that may aid this process. In addition, it appears surprising that those studies published to date, few, if any, consider the impact of well-established personality traits in behaviour change models. Therefore, the project aims to conduct a series of novel studies to unpick the theoretical underpinnings linking preservative cognition and health behaviours while also accounting for personality factors that may moderate behaviour change. Ultimately, built upon previous work within the Laboratory for Stress and Health, the PhD aims to develop a stress management support tool to help reduce daily preservative cognition and postpone cognitive worry and their corresponding effects on behaviours that have been liked to negative health outcomes (over/under eating & alcohol consumption).

在压力文献中，最近的一系列重要研究表明，即使在没有身体应激源的情况下，认知表征本身也足以引发生理压力反应，而这种反应一旦持续，就会增加与压力相关的疾病的可能性。这种认知倾向，被称为防腐剂认知假说，现在受到了学术界的极大关注，最近的荟萃分析报告称，它对身体健康和福祉有重大影响。然而，尽管如此，很少有研究试图对抗坚持不懈对健康结果的负面影响，到目前为止，还没有人试图开发出可能有助于这一过程的干预措施。此外，令人惊讶的是，到目前为止发表的那些研究几乎没有考虑到成熟的个性特征对行为变化模型的影响。因此，该项目旨在进行一系列新颖的研究，以打破将防腐剂认知和健康行为联系起来的理论基础，同时也考虑到可能缓和行为变化的人格因素。最终，在压力与健康实验室以前工作的基础上，该博士的目标是开发一种压力管理支持工具，以帮助减少日常防腐认知，推迟认知担忧及其对那些对负面健康结果(过量/不足饮食和饮酒)的行为的相应影响。
