The main questionnaire was translated into the Persian by using the Translation-back Translation method. In order to standardize and validate the questionnaire, 10 elites in the field of the motor imagery and sports psychology, filled the questionnaires in order to determine the content validity ratio (CVR) and the content validity index (CVI). After a primitive study, the necessary modifications were applied.The questionnaire reliability was investigated by the test-retest reliability method and the Cronbach's alpha. Results indicated that the CVR and CVI are 0.62 and 0.79, respectively, which confirms the validity of the questionnaire. The reliability was confirmed by the internal consistency method which value was obtained higher than 0.7. For evaluating the ability of children in motor imaginary, a reliable method should be used.According to obtained results of the current work, the questionnaire benefits from a suitable reliability and validity.
