The Measure Athletes’ Volition consists of 23 items that measure six elements of volitional competences. The purpose of the present study was to examine whether a subset of these items could form a short version of the scale; to provide evidence for the structural validity and internal consistency of the short version; and to test validity issues of the new scale. A total of 831 individuals from three different samples completed the long version of the scale. Results indicated that the short version consisted of 15 items that measured volitional competences of persistence, expediency, and purposefulness. This scale had acceptable internal consistency and construct validity (differences between groups and convergent and concurrent validity). In conclusion, the short version of the scale is a reliable and valid measure for volitional competences.
