Clinical utility of the Metacognitions Questionnaire 30 in people with epilepsy.

ABSTRACT

OBJECTIVE: The Metacognitions Questionnaire 30 (MCQ-30) has been widely used to assess metacognitive beliefs and processes linked to emotional disorders. The aim of the present study was to test the utility of the MCQ-30 in assessing metacognitions in people with epilepsy. METHODS: Three hundred forty-nine people with epilepsy completed the MCQ-30 and self-report measures of anxiety and depression at two time points, 12 months apart. Factor analyses and structural equation modeling were used to test the factor structure, internal consistency, and convergent validity of the MCQ-30. RESULTS: Confirmatory and exploratory factor analyses supported the original five-factor structure and demonstrated that each factor had good to excellent levels of internal consistency. CONCLUSION: The MCQ-30 is a robust measure of metacognitive beliefs and processes and has clinical utility in PWE.
