“…The Metacognitive Theory maintains that nonfunctional beliefs about cognitions, which form the metacognitions, are central to the improvement and maintenance of psychological disorders (Wells, 2000;Wells & Mathews, 1994). For example, these beliefs have also been found to be related to other distress phenomena, for instance, perfectionism (Flett, Hewitt, Blankstein, & Gray, 1998), eating disorders (e.g., Vitousek, 1996), pathological gambling (Lindberg et al, 2011), physical symptoms of illness (Aydin, 1997), suicide-related responses (Nock & Kazdin, 2002), seasonal affective disorder (e.g., Rohan, Sigmon, & Dorhofer, 2003), and generalized anxiety disorder . Moreover, Wells' (2009) metacognitive therapy (MCT) model accentuates the importance of both cognitive and metacognitive dimensions of thinking.…”
