The metacognitive model of generalized anxiety disorder (GAD) places worrying, meta-worry ("worry about worry") and corresponding underlying metacognitive beliefs (i.e., beliefs about worry) as central in the maintenance of symptoms. Previous research has demonstrated significant relationships between these factors and symptoms, but no study has tested the statistical fit of this influential model including its hypothesized components and the suggested paths between them. The aim of the current study was therefore to evaluate the fit of the metacognitive model of GAD. A total of 312 participants constituting an analogue GAD sample were included in a cross-sectional study and completed self-report measures of anxiety and depression symptoms and scales relevant to the metacognitive model. Metacognitions, worry, and meta-worry in their hypothesized order provided a good model fit and explained significant and substantial variance in symptoms. These results provide further support for the metacognitive model of GAD and demonstrates separate and unique contributions from worry and meta-worry to generalized anxiety symptoms of which meta-worry was the most influential.
广泛性焦虑障碍（GAD）的元认知模型将担忧、元担忧（“对担忧的担忧”）以及相应的潜在元认知信念（即关于担忧的信念）置于症状维持的核心位置。先前的研究已经证明了这些因素与症状之间存在显著关系，但尚无研究检验这一有影响力的模型（包括其假设的组成部分以及它们之间建议的路径）的统计拟合度。因此，本研究的目的是评估GAD元认知模型的拟合度。一项横断面研究纳入了总共312名构成模拟GAD样本的参与者，他们完成了焦虑和抑郁症状的自我报告测量以及与元认知模型相关的量表。按照假设顺序排列的元认知、担忧和元担忧提供了良好的模型拟合，并解释了症状中显著且大量的变异。这些结果为GAD的元认知模型提供了进一步支持，并证明了担忧和元担忧对广泛性焦虑症状的单独且独特的贡献，其中元担忧的影响最大。
