The original form of decision specific reinvestment scale comprises 13 items and 2 subscales including: decision rumination and decision reinvestment and movement specific reinvestment scale comprises 10 items and 2 subscales including movement self-consciousness and conscious motor processing. 239 questionnaires completed by 18-35 years-old athletes. Construct validity were used to estimate models. Confirmatory factor analysis used for validation of structure of scales, Cronbach's alpha coefficient used for internal consistency and intra-class correlation coefficient under test-retest method used to study temporal reliability of scales. The result showed that Persian version of the scales provided support for the two-factor model of both scales, thus validity and reliability confirmed. In conclusion, Persian version of the decision and movement specific reinvestment scales recommended to measure athlete's propensity to reinvestment in competitive conditions.
