[Psychometric approach of metacognition: Pilot study in clinical population].

Metacognition describes the process of thinking about one's own thought processes. This concept was introduced by Flavell in 1979 and has since been widely developed in the cognitive approach to mood and anxiety disorders. As it happens, many recent studies have underlined the links between metacognition and anxio-depressive symptoms, pointing out the interest of assessing its various dimensions. 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 the vulnerability to and the maintenance of emotional disorders. The aim of this study was twofold: firstly to adapt and validate a French version of the short form of the Metacognitions Questionnaire (MCQ-30) and to assess its psychometric properties in a clinical sample, and secondly to investigate metacognitive predictors of anxiety and depression in this sample. The sample included 55 clinical participants (24 men, 31 women, mean age=51.33±14.62) with DSM-IV-TR psychiatric disorders (major depression, bipolar disorder and obsessive-compulsive disorder). Instrument reliability (internal consistency), construct validity (confirmatory factor analysis), and convergent validity were measured. The total score and the five subscale scores were also compared with previous results in non-clinical samples. Reliability analyses indicated that the French version of the MCQ-30 possessed satisfactory internal consistency (Cronbach α=0.84), and confirmatory factor analysis supported the MCQ's original five-factor structure. Correlation with measurements of depression, anxiety and pathological worry demonstrated convergent validity (r=0.62, P<0.01 for anxiety; r=0.47, P<0.01 for rumination; r=0.33, P<0.05 for depression). Moreover, our clinical sample scored higher on the global scale when compared to previous non-clinical samples (mean score=71.85±13.57 while previous studies global scores ranged from 48.41±13.31 to 65.89±17.17). Consistent with others studies, negative beliefs about worry concerning uncontrollability and danger, as well as beliefs about the need to control thoughts were the strongest predictors of pathological worry (respectively r=0.68, P<0.01 and r=0.48, P<0.01) and depression (respectively r=0.45, P<0.01 and r=0.39, P<0.01), providing further support for the validity of the measure. These findings provide general support for the internal consistency of the French version of the MCQ-30, as well as its five-factor structure and its good concurrent validity in a clinical sample. They also confirm that this version is a valuable tool for the assessment of various dimensions of metacognition, in relation to the anxio-depressive symptomatology and the subsequent management of patients.

Adaptation and validation of the Metacognition Questionnaire (MCQ-30) in Spanish clinical and nonclinical samples.

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. 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. 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. This study did not assess the test-retest reliability. The MCQ-30 has good psychometric properties and can be used to evaluate several dimensions of metacognition in both clinical and nonclinical samples.
