Cognitive behavioural models of hypochondriasis assume that dysfunctional illness-related beliefs are involved in the genesis and maintenance of the disorder. The role that other more general dysfunctional beliefs about thoughts play in this disorder has also been highlighted. Internal triggers such as illness-related intrusive thoughts could activate these beliefs.
The present paper examines whether general dysfunctional beliefs about distressing thoughts, such as intolerance of uncertainty, over-estimation of threat, and thought-action fusion-likelihood, mediate between illness-related intrusive thoughts and health anxiety symptoms.
A group of participants composed of individuals with hypochondriasis (n = 31; 51.5% women; mean age = 32.74 years, SD = 9.96) and community individuals (n = 219; 54.3% women; mean age = 39.56 years, SD = 15.20) completed a series of questionnaires to assess illness-related intrusive thoughts (INPIE), dysfunctional beliefs about thoughts (OBSI-R), and health anxiety symptoms (SHAI).
Results from a multiple parallel mediation analysis indicate that over-estimation of threat partially mediated the relationship between illness-related intrusive thoughts and health anxiety symptoms.
The results support the importance of the tendency to over-estimate the threat in the relationship between intrusive thoughts related to illness contents and health anxiety. Conceptual and clinical implications of these results are discussed.
疑病症的认知行为模型假设，与疾病相关的功能失调信念在疾病的发生和维持中起作用。其他与思维相关的更普遍的功能失调信念在这种疾病中的作用也已被强调。例如与疾病相关的侵入性思维等内部触发因素可能会激活这些信念。
本文探讨了与痛苦思维相关的一般功能失调信念（如无法容忍不确定性、对威胁的高估和思维-行动融合倾向）是否在疾病相关的侵入性思维和健康焦虑症状之间起中介作用。
一组由疑病症患者（n = 31；51.5%女性；平均年龄 = 32.74 岁，标准差 = 9.96）和社区个体（n = 219；54.3%女性；平均年龄 = 39.56 岁，标准差 = 15.20）组成的参与者完成了一系列问卷，以评估与疾病相关的侵入性思维（INPIE）、思维的功能失调信念（OBSI-R）和健康焦虑症状（SHAI）。
多重平行中介分析的结果表明，对威胁的高估部分中介了疾病相关侵入性思维与健康焦虑症状之间的关系。
结果支持在与疾病相关的侵入性思维内容和健康焦虑之间，对威胁的高估倾向的重要性。讨论了这些结果的概念和临床意义。
