Psychometric Analysis of Persian Version of Movement Imagery Questionnaire-Children Form (MIQ-C)

Background: Previous studies have shown that Movement Imagery ability is effective in learning and motor function in the sport as well as in rehabilitation. So, self-reporting questionnaires have been developed to evaluate the ability of Movement Imagery in adults (e.g. MIQ-۳) to be validated in Iran. There is currently no proper tool to use for children in Iran. Objective: To fill this gap, the focus of this study was to examine the functional structure of the Children's Movement Imagery Questionnaire. Methods: The statistical population included children from ۷ to ۱۲ years old (۱۳۵ boys, ۱۰۹ girls) who were selected by random cluster sampling. At first, the questionnaire was translated into Persian. After necessary corrections, both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to examine the factor structure. Results: Exploratory factor analysis showed that the present log consists of three folded scales and ۱۲ materials that ultimately were tested and validated the three-factor model through the confirmatory factor analysis. Also, the total reliability for the factors was calculated by Cronbach's alpha method and equaled with ۰.۸۴۵, which indicates the reliability of the mentioned logic. Conclusion: The Persian version of the current questionnaire is recommended to measure the children Imagery ability, from ۷ to ۱۲ years of age in the Persian language.
