Abstract
The VMIQ-2 has been proven a valid and useful psychometric tool to measure the ability of vividness of movement imagery in sports. However, no validity study has been reported in Greek. The purpose of the present study was to examine the validity and reliability of the VMIQ-2 into Greek in adult athletes derived from various sports activities and different athletic levels. The VMIQ-2-GR (n = 160) was examined for translation, construct and discriminant validity, and also for internal consistency and test–retest reliability. CFA did not show acceptable global fit indices and only the index of (x2/df) showed an acceptable fit. The resulting factors of the EFA highlighted the discrepancy between the Greek version and the original version of the VMIQ-2. The results of the discriminant validity confirmed that the VMIQ-2-GR was well discriminated between subgroups of athletes and, therefore, showed a good discriminant validity. The Cronbach a coefficient was excellent at both measurements (> 0.92 in all cases for all factors). The Spearman rho correlation coefficients were statistically significant (< 0.001) with values > 0.47. The findings of the VMIQ-2–GR suggest that it is a valid and reliable tool and it can be used by sports psychologists, sports physiotherapists, coaches and researchers who aim to apply MI in the Greek athletic population.
