The Factor Structure and Concurrent Validity of the Korean Version of the Metacognitions Questionnaire 30 (K-MCQ-30)

Objectives: We aimed to examine the factor structure of a Korean version of the Metacognitions Questionnaire 30 (K-MCQ-30) and to further evaluate its concurrent validity. Method: Confirmatory factor analyses were conducted on the data sets from two independent samples of Korean college students (n = 662; n = 664). Correlation and multiple regression analyses were conducted on the cross-sectional data from another sample (n = 97). Results: The 5-factor model of the K-MCQ-30 showed a good fit to the first sample after minor modification. The revised 5-factor model was replicated with the second sample. Five factors of the K-MCQ-30 had positive correlations with measures of emotional disorder symptoms and predicted each of the symptoms in different ways. Conclusions: These results provide general support for the 5-factor structure of the K-MCQ-30 and its good concurrent validity in nonclinical samples.
