Psychometric properties of the Dutch version of the Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A) in non-clinical adolescents and adolescents with obsessive-compulsive disorder.

Although the meta-cognitive model (Wells, 1997, 2000) for obsessive-compulsive disorder (OCD) has clearly influenced research and treatment of OCD, little research has been performed in youth samples. In the present study the psychometric properties of the Dutch Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A; Cartwright-Hatton et al., 2004) were examined in a clinical sample of adolescents with OCD (N = 40, 12-18 years) and a non-clinical sample (N = 317; 12-18 years). Results provided support for the 5-factor structure, and showed fair to good internal consistency and generally good retest reliability. Overall, adolescents with OCD reported more meta-cognitive beliefs than non-clinical adolescents. Several subscales were associated with self-reported obsessive-compulsive symptoms, anxiety and depression, but not with clinician-rated OCD severity. In conclusion, results suggest that the Dutch MCQ-A is a reliable and valid questionnaire to examine meta-cognitive beliefs in adolescents.
