To test the hypothesis that dysfunctional metacognitions might be a general vulnerability factor for anxiety disorder, metacognitive beliefs among patients with obsessive-compulsive disorder (OCD), patients with panic disorder (PD), and healthy subjects (HS) were studied. Correlations between metacognitive beliefs, OCD, and PD symptoms were also investigated.
Patients with OCD (n = 114), patients with PD (n = 119), and HS (n = 101) were assessed with the Metacognition Questionnaire (MCQ).
Patients with OCD and those with PD scored significantly higher than HS on the MCQ in 2 dimensions: negative beliefs about worry concerning uncontrollability and danger as well as beliefs about the need to control thoughts dimensions. No difference in MCQ scores was observed between the OCD and PD groups. The former 2 MCQ dimensions were positively correlated with the degree of indecisiveness in patients with OCD, whereas the MCQ negative beliefs about worry positively correlated with the average intensity of anticipatory anxiety in patients with PD.
The presence of dysfunctional metacognitions in both patients with OCD and those with PD suggests that such beliefs can represent not only generic vulnerability factors for anxiety disorders but also elements that contribute to maintaining the disorder, as evidenced by their associations with aspects of OCD and PD symptoms.
检验元认知功能障碍可能是焦虑障碍的一般易患因素这一假设，研究强迫症（OCD）患者、惊恐障碍（PD）患者和健康对照者（HS）的元认知信念。还调查了元认知信念与 OCD 和 PD 症状之间的相关性。
采用元认知问卷（MCQ）对 114 例 OCD 患者、119 例 PD 患者和 101 例 HS 进行评估。
OCD 患者和 PD 患者在 MCQ 的 2 个维度上的得分显著高于 HS：对无法控制和危险的担忧的消极信念以及需要控制思想的信念维度。OCD 和 PD 组之间的 MCQ 评分无差异。MCQ 的前两个维度与 OCD 患者的犹豫不决程度呈正相关，而 MCQ 对担忧的消极信念与 PD 患者的预期焦虑平均强度呈正相关。
OCD 患者和 PD 患者存在功能失调的元认知信念表明，这些信念不仅可以代表焦虑障碍的一般易患因素，而且可以作为维持障碍的因素，这可以从它们与 OCD 和 PD 症状的各个方面的关联中得到证明。
