The effect of mindfulness and metacognition on anxiety symptoms: a case-control study

Abstract

Background: Anxiety disorders (ADs) are associated with numerous psychiatric disorders; despite the efforts in psychotherapy models targeting their etiology, novel treatment strategies are still developing. We aimed to assess whether mindfulness and metacognition differ between patients with ADs and healthy controls (HCs) and whether the symptom severity of ADs is related to mindfulness and metacognition among patients. Two-hundred participants were enrolled in this study. Structured clinical interview, sociodemographic form, Five Facet Mindfulness Questionnaire-Short Form, Metacognition Questionnaire-30, and Hamilton Anxiety Rating Scale were administered. Multivariate analysis of covariance was conducted to compare the groups in terms of mindfulness and metacognition. Correlation and multiple linear regression analyses were performed to measure the association between the variables. Results: The main finding indicates that positive beliefs about worry are associated with reduced symptom severity of ADs. Furthermore, HCs have more positive beliefs about worry and nonjudging of inner experience compared to patients with ADs, who utilize negative beliefs about uncontrollability and danger and need to control thoughts to a greater extent. Conclusions: This study demonstrates that dysfunctional metacognitive beliefs may influence the anxiety severity of adult patients. We suggest that focusing on reducing maladaptive metacognitions may be supportive of AD improvement.
