ABSTRACT
MCT is the only approach that explicitly focuses on modifying negative metacognitive beliefs. Negative metacognitive beliefs about thoughts or perseverative thinking can be subdivided into beliefs about worry/rumination being uncontrollable and beliefs about the danger of this thinking style. Typical uncontrollability beliefs are that worrying/ruminating is beyond control, whereas examples of danger-related beliefs include, ``worrying could make me go crazy'' and ``people will reject me if they knew how much time I spent dwelling on my situation''. During episodes of perseverative thinking, these negative beliefs are activated, leading to extended thinking and negative appraisals of worrying or ruminating, which exacerbate anxiety, depressive affect and other distressing emotions.
