title: Adaptation and validation of the Metacognition Questionnaire (MCQ-30) in Spanish clinical and nonclinical samples.
abstract: BACKGROUND
  The short form of the Metacognitions Questionnaire is a brief multidimensional measure of a range of metacognitive processes and metacognitive beliefs about worry and cognition relevant to vulnerability to and maintenance of emotional disorders. The aim of the study was adapt and validate a Spanish version of the short form of the Metacognitions Questionnaire (MCQ-30) and to evaluate its psychometric properties in clinical and nonclinical samples.
  
  
  METHODS
  The MCQ-30 was administered to a sample of 316 patients with psychiatric disorders (anxiety, depression, and eating disorders) and to a sample of 169 individuals belonging to the general population. Instrument reliability (internal consistency), construct validity (confirmatory factor analysis [CFA], convergent validity, known groups) and responsiveness were measured.
  
  
  RESULTS
  The clinical sample scored the highest on all factors when compared to nonclinical sample. The exploratory factor analysis supported the MCQ׳s original five-factor solution. The CFA suggested a good fit of the model. Correlation with measure of worry demonstrated convergent validity. Known-groups validity was supported by significant differences in the MCQ-30 mean scores according to certain variables, such as educational level and employment status.
  
  
  CONCLUSIONS
  This study did not assess the test-retest reliability.
  
  
  CONCLUSIONS
  The MCQ-30 has good psychometric properties and can be used to evaluate several dimensions of metacognition in both clinical and nonclinical samples.
