Introduction: Metacognitive constructs have shown promise in explaining the symptoms of Obsessive-Compulsive Disorder (OCD). Few studies have examined the role of metacognitions in symptom dimensions of OCD, despite mounting clinical, neuropsychological and imaging evidence for the distinctiveness of these dimensions.

Methods: Metacognitions were assessed using the Metacognitions Questionnaire (MCQ-30) in 51 participants with DSM IV OCD and 46 healthy controls. The Maudsley Obsessional Compulsive Inventory (MOCI) was used to quantify symptom dimensions, along with the Hamilton Anxiety Rating Scale (HAM-A) for anxiety, and Hamilton Depression Rating Scale (HAM-D) for depression.

Results: Individuals with OCD differed from healthy controls on beliefs of uncontrollability and danger when depression and anxiety were controlled for. Correlations between metacognitive beliefs and obsessive-compulsive symptom dimensions were largely similar across the OCD and healthy control groups. Hierarchical regression showed that contributed to checking, cleaning and rumination symptoms; to symptoms of slowness; to doubt symptoms; to checking symptoms.

Conclusions: Specific associations between metacognitive variables and the different symptom dimensions of OCD are evident, however, severity of anxiety and depression also contribute to these associations.
