Psychometric properties of the Metacognitions about Smartphone Use Questionnaire (MSUQ) in a sample of iranians.

Research has shown that metacognitions are associated with addictive behaviors. This study aimed to evaluate the psychometric properties (i.e., factor structure, reliability, and predictive validity) of the Persian Metacognitions about Smartphone Use Questionnaire (Persian MSUQ). A community sample of 618 participants (63.6% female, mean age = 27.31 ± 8.95 years; age range: 15-67 years) was recruited in Iran. The results of exploratory factor analysis revealed that the Persian MSUQ had a three-factor structure, similar to the parent version, named positive metacognitions about emotional and cognitive regulation, negative metacognitions about uncontrollability and cognitive harm, and positive metacognitions about social advantages. The confirmatory factor analysis indicated that the three-factor structure of the Persian MSUQ had appropriate fit. Cronbach's alphas for the three factors were 0.89, 0.88, and 0.70, respectively. Test-retest coefficients over a 6-week interval showed good reliability for the Persian MSUQ total score (ICC = 0.81; 95% CI: 0.72-0.87). Regression analyses showed that metacognitions about smartphone use predicted problematic smartphone use independently of anxiety and depression. The findings suggest that the Persian MSUQ has appropriate psychometric properties in the Iranian context.
