Psychometric properties of an Arabic translation of the short form of the metacognition questionnaire (MCQ-30) in a non-clinical adult sample

Background: Previous linguistic validations of the 30-item Metacognition Questionnaire (MCQ-30) have been performed in Western/Eastern populations, and no Arabic validated version exists to date for the wide Arabic-speaking populations in the Middle East-North African region and abroad. In this regard, we sought through the present study to test the psychometric properties of an Arabic translation of the MCQ-30 in a sample of Arabic-speaking community adults from Lebanon. Methods: The sample of this cross-sectional study consisted of 423 participants (mean age: 38.13 ± 11.03 years; 61.2% females). The Metacognition Questionnaire-short form, Teruel Orthorexia Scale and Emotion regulation questionnaire were used to assess metacognition, orthorexia nervosa and emotion regulation (cognitive reappraisal and expressive suppression) respectively. Results: Findings of Confirmatory Factor Analyses revealed that the five-factor model provided a good fit to the data. McDonald’s ω coefficients ranged from 0.78 to 0.94 for the five MCQ-30 subscales, and was of 0.93 for the total score, hence supporting the adequacy of scale reliability. Results also supported configural, metric, and scalar equivalence of the five-factor model across gender groups. The MCQ-30 subscales showed patterns of correlations with the emotion regulation and disordered eating constructs in the expected directions, providing evidence of the criterion-related validity of the measure. In particular, positive emotion regulation strategies (i.e., cognitive reappraisal) were negatively correlated with cognitive self-consciousness and need to control thoughts; whereas maladaptive emotion regulation strategies (i.e., expressive suppression) showed positive correlations with lack of cognitive confidence, negative beliefs and need to control thoughts. Additionally, all metacognition dimensions (except for cognitive self-consciousness) were significantly and positively correlated with higher levels of orthorexia nervosa behaviors. Conclusions: Our findings preliminarily suggest that the scale is valid, reliable, and can be recommended for use among the broad Arabic-speaking community worldwide.
