Contemporary conceptual models posit that different core variables contribute to worry, including intolerance of uncertainty (IU), metacognitive beliefs, and experiential avoidance. To date, a concurrent investigation of the incremental explanatory power of these variables in accounting for worry severity remains unexamined. The present study sought to address that gap in the literature.
DESIGN/METHODS: Participants endorsing frequent worry (N = 127) completed self-report measures assessing IU, metacognitive beliefs, and experiential avoidance during an online session. Participants later attended an in-person lab-based session where they completed a worry episode and in-vivo worry severity was assessed following the worry episode.
IU, negative metacognitive beliefs, and experiential avoidance each shared a bivariate association with post-episode worry severity. However, in multivariate analyses, only baseline worry severity and negative metacognitive beliefs surrounding the dangerousness and uncontrollability of worry predicted post-episode worry severity.
The present results further underscore links between negative metacognitive beliefs and worry.
当代概念模型认为，不同的核心变量会导致担忧，包括不确定性容忍度（IU）、元认知信念和体验回避。迄今为止，这些变量对担忧严重程度的额外解释力的并行研究尚未得到检验。本研究旨在填补文献中的这一空白。
设计/方法：在一次在线会议上，参与者（N=127）完成了自我报告的 IU、元认知信念和体验回避评估，这些参与者经常担心。参与者后来参加了一个基于实验室的现场会议，在担心事件之后，他们完成了一个担心事件，并评估了现场的担心严重程度。
IU、消极的元认知信念和体验回避都与事后担忧严重程度存在双变量关联。然而，在多变量分析中，只有基线担忧严重程度和对担忧的危险性和不可控性的消极元认知信念预测了事后担忧严重程度。
本研究结果进一步强调了消极元认知信念与担忧之间的联系。
