title: [Standardization of Turkish form of metacognition questionnaire for children and adolescents: the relationships with anxiety and obsessive-compulsive symptoms].
abstract: OBJECTIVE
  There were two aims of the present study. The first aim was to evaluate the psychometric properties of the Metacognition Questionnaire for Children and Adolescents (MCQ-C) among Turkish children and adolescents. The second aim was to analyze relationships between metacognitive processes, anxiety, and obsessive-compulsive symptoms among Turkish children and adolescents.
  
  
  METHODS
  Four hundred and seventy primary and high school students (205 female, 265 male) from 71 different public schools in Istanbul participated in the study. Three questionnaires were used. In addition to MCQ-C, State-Trait Anxiety Scale for Children and Maudsley Obsessive-Compulsive Inventory were administrated in the study.
  
  
  RESULTS
  The Turkish form of MCQ-C showed acceptable to good test-retest reliability and good internal consistency and convergent validity. Construct validity was evaluated by confirmatory factor analysis using AMOS. The fit indices of confirmatory factor analysis suggested an acceptable fit to a four-factor model consistent with the original MCQ-C. Significant positive correlations between subscales of MCQ-C and measures of anxiety and obsessive-compulsive symptoms provided further support for the convergent validity of the Turkish form of MCQ-C. Group comparisons showed that the effect of age was significant on the MCQ-C positive meta-worry subscale only; on the other hand, effect of gender was significant on MCQ-C negative meta-worry subscale and total score.
  
  
  CONCLUSIONS
  The psychometric properties of Turkish form of MCQ-C showed that the instrument is a valuable addition to the assessment of metacognition for Turkish children and adolescents.
