Translation and validation of the movement imagery questionnaire-3 second French version

Abstract

IntroductionMotor imagery (MI) can be defined as the mental simulation of an action without performing it. Its effectiveness can be substantially influenced by imagery ability, and it is currently accepted that three main modalities are used in MI (kinaesthetic imagery, and internal or external visual imageries). In the context of rehabilitation, MI combined with physical therapy is further known to facilitate functional improvements, and promote cortical reorganization and long-term recovery. This study aimed to test the reproducibility and the validity of constructs (internal consistency and factorial structure) of the Movement Imagery Questionnaire-3 Second French version (MIQ-3Sf). MethodThe internal consistency as well as the validity of constructs and the test-retest inter-rate reproducibility of the MIQ-3Sf was examined, in 553 participants, for the kinaesthetic and visual items. ResultsThe composite reliability scores (≥0.92) and the intraclass correlation coefficients (>0.88) for the kinaesthetic, internal visual and external visual imagery subscales revealed satisfactory internal consistency and reproducibility. Moreover, Pearson correlations revealed a strong relationship between the MIQ-3Sf and the MIQ-3f. Conclusions/Implications. The MIQ-3Sf can be considered as a valid, reliable and useful questionnaire for examining MI ability in the context of rehabilitation.
