Too much thinking about thinking?: Metacognitive differences in obsessive-compulsive disorder.
Negative appraisals of intrusive thoughts and beliefs about the importance of thoughts are considered core mechanisms in cognitive models of obsessive-compulsive disorder (OCD). In refinements of cognitive theory, differences in metacognitive processes have been emphasized. Cartwright-Hatton and Wells [J. Anxiety Disord. 37 (1997) 279-296] found that cognitive self-consciousness (CSC), a tendency to be aware of and monitor thinking, was the only metacognitive dimension that differentiated OCD patients from patients with generalized anxiety disorder. To evaluate the relative importance of different cognitive processes to OCD, we administered an expanded CSC scale and two state-of-the-art measures of thought appraisals and beliefs. Scores on the CSC scale reliably differentiated OCD patients (n=30), from an anxious comparison group (OAD, n=25) after controlling for scores on the two cognition measures. The tendency to excessively reflect upon one's cognitive processes may increase opportunities for negative appraisals of intrusive thoughts, foster over-importance of thought beliefs, and increase the likelihood of developing OCD.
