The Psychometric Properties of the Persian Version of the Sport Imagery Questionnaire for Children (SIQ-C)

The purpose of this study was to determine the factorial validity and reliability of Persian version of the Sport Imagery Questionnaire for Children (SIQ-C). For this purpose, a total of 235 teen athletes including 124 male (M = 11.77, SD = 1.59) and 111 female (M = 12.02, SD = 1.44) were selected by random cluster sampling and completed the Persian Version of the Sport Imagery Questionnaire for Children. Accuracy of translation was verified through back-translation method by three sport psychologists and three English teaching specialists. Confirmatory factor analysis (CFA) based on structural equations was used for assessing construct validity, and internal consistency of the questionnaire was evaluated using Cronbach’s alpha coefficient. Also, temporal reliability of the items was evaluated with intra-class correlation coefficient using test-retest method with 2-week interval. The results showed that the Persian version of Sport Imagery Questionnaire for Children had acceptable fit indices (RMSEA = 0.043, CFI = 0.95, TLI = 0.96), total internal consistency (0.74) and total temporal reliability (0.76). Therefore, the Persian version of the Sport Imagery Questionnaire for Children has good reliability and validity and it can be characterized as a valid and reliable tool to study and evaluate the Sport Imagery of Iranian children.
