Psychometric Properties of the Metacognitions Questionnaire-30 (MCQ-30) in Older Norwegian Adolescents

Dysfunctional metacognitive beliefs have been established as a transdiagnostic correlate of anxiety and depression in adults and are considered a central mechanism of persistent emotional distress according to the metacognitive model of psychological disorders. However, the importance of metacognitions for distress and emotional disorder in adolescence is far less researched, and to investigate this further there is a need for reliable and valid assessment tools. The Metacognitions Questionnaire-30 (MCQ-30) might be a suitable and valid assessment tool in adolescents with the implication that it can be used to research the role of metacognitions in youth mental health and track how metacognitions change and relate to outcomes over time from adolescence to adulthood. We therefore aimed to examine the psychometric properties of the MCQ-30 in an Upper Secondary School-sample of 494 Norwegian adolescents, aged 16- to 18-years old. A confirmatory factor analysis indicated a good fit for the proposed five-factor structure and evidence for measurement invariance was supported across sex and groups of anxiety severity. The factors showed acceptable to good internal consistency and there was support for convergent validity. In conclusion, these findings indicate that the adult version of the MCQ-30 can be applied in Norwegian adolescents from 16-years old.
