Abstract Objective According to the intolerance of uncertainty model (IUM) of generalised anxiety disorder (GAD), four components contribute to the development and maintenance of worry in GAD. They are intolerance of uncertainty (IU), positive beliefs about worry, negative problem orientation, and cognitive avoidance. Recent studies report that the relationship between IU and worry is mediated by positive beliefs about worry and negative problem orientation. The present study examined whether these mediation relationships emerge when the two subtypes of IU, prospective and inhibitory IU, are considered separately. Method A convenience sample of 160 members of the Australian public completed an online questionnaire assessing each IUM component, worry, and depression. Results Positive beliefs about worry and negative problem orientation mediated the relationship between IU and worry. Only positive beliefs about worry mediated the relationship between prospective IU and worry, while only negative problem orientation mediated the relationship between inhibitory IU and worry. Conclusions The results may imply that the two IU subtypes influence worry via differing pathways. The findings have implications for treatments targeting components of the IUM in individuals with GAD and other anxiety disorders.

不确定性亚型的担忧与不容忍之间的关系

摘要 目的根据广泛性焦虑症(GAD)的不确定性不耐受模型(IUM),有四个组成部分有助于GAD焦虑的发展和维持。它们是对不确定性 (IU) 的不容忍、对担忧的积极信念、消极的问题导向和认知回避。最近的研究报告说,IU 和担忧之间的关系是由对担忧的积极信念和消极的问题取向介导的。本研究检验了当 IU 的两种亚型(前瞻性和抑制性 IU)分别考虑时是否会出现这些中介关系。方法 由 160 名澳大利亚公众组成的便利样本完成了一份在线问卷,评估了 IUM 的每个组成部分、担忧和抑郁。结果 关于担心的积极信念和消极的问题导向介导了 IU 和担心之间的关系。只有关于担心的积极信念介导了预期 IU 和担心之间的关系,而只有消极问题导向介导了抑制性 IU 和担心之间的关系。结论 结果可能意味着两种 IU 亚型通过不同的途径影响担忧。这些发现对针对 GAD 和其他焦虑症患者 IUM 成分的治疗具有重要意义。结论 结果可能意味着两种 IU 亚型通过不同的途径影响担忧。这些发现对针对 GAD 和其他焦虑症患者 IUM 成分的治疗具有重要意义。结论 结果可能意味着两种 IU 亚型通过不同的途径影响担忧。这些发现对针对 GAD 和其他焦虑症患者 IUM 成分的治疗具有重要意义。
