The aim of this study was to investigate the contribution of cognitive, emotional and personality factors to the experience of fatigue severity in healthy adult individuals. Specifically, the study examined whether fatigue catastrophising and emotional distress mediated the relationships between neuroticism, general irrational and rational thoughts to fatigue severity. One hundred and eighty nine university students and community volunteers completed self-report questionnaires assessing fatigue catastrophising and symptom severity, neuroticism, general rational and irrational thoughts and emotional distress. A series of correlational and path analyses were conducted to test the study hypotheses. Neuroticism and more general negative, irrational cognitions were associated with elevated fatigue catastrophising and fatigue severity, whereas more adaptive, rational cognitions were related to lower fatigue catastrophising and fatigue severity. Both elevated fatigue catastrophising and emotional distress uniquely and simultaneously mediated the relationships between irrational and rational cognitions and neuroticism to fatigue severity. These findings demonstrate that cognitions play a role in fatigue severity. The results have implications in the assessment and treatment of fatigue disturbances in the general community.
本研究旨在探讨认知、情绪和人格因素对健康成年人疲劳严重程度的影响。具体而言，本研究考察了疲劳灾难化和情绪困扰是否在神经质、一般不合理和理性思维与疲劳严重程度之间起中介作用。189 名大学生和社区志愿者完成了自我报告问卷，评估疲劳灾难化和症状严重程度、神经质、一般理性和非理性思维以及情绪困扰。进行了一系列相关和路径分析来检验研究假设。神经质和更一般的消极、非理性认知与疲劳灾难化和疲劳严重程度升高有关，而更适应的、理性的认知与疲劳灾难化和疲劳严重程度降低有关。疲劳灾难化和情绪困扰的升高都可以独特地和同时地中介非理性和理性认知与神经质对疲劳严重程度的关系。这些发现表明认知在疲劳严重程度中起作用。这些结果对一般人群中疲劳障碍的评估和治疗具有启示意义。
