Psychometric Analysis of Persian Version of Movement Imagery Questionnaire for Children (MIQ-C) Using Item Response Theory

Previous studies have shown that Movement Imagery ability is effective in motor performance and learning in sports and rehabilitation. Appropriate inventory for assessment of this ability in adults (e.g. MIQ-3) development and validated in Iran. However, there is currently no standard tool for using children in Iran. To address this gap, we sought to examine the psychometric properties of the Persian version of imagery ability questionnaire for children (MIQ-C). The statistical population included children from 7 to 12 years old (135 boys, 109 girls) who were selected by random cluster sampling. Results replicated that most items had good discrimination and threshold parameters and high item information values and IRT replicated that all questions have an appropriate coefficient of detection (a) and threshold (b). So the Persian version of the current questionnaire is recommended to measure the Movement Imagery ability to children from 7 to 12 years of age in Persian.
