The Injury-Psychological Readiness to return to sport (I-PRRS) scale and the Sport Confidence Inventory (SCI): A cross-cultural validation

The purpose of this study was to cross-culturally validate in the Italian language the I-PRRS and the SCI. Cross-sectional study. Injured Italian athletes. We recruited male (n = 73) and female (n = 27) athletes who returned to practice after having completed the rehabilitation. The measures comprised the I-PRRS, the SCI, and the Italian Mood Scale (ITAMS). Athletes completed the questionnaires within 1 day before their first official competition following injury. We investigated the construct validity, the internal consistency, and the concurrent validity of the I-PRRS and SCI with the ITAMS. Confirmatory Factor Analysis supported the two-factor structure of the I-PRRS (Confidence in performance capability and Confidence in recovery) and the three-factor structure of the SCI (SC-Physical Skills and Training, SC-Cognitive Efficiency, and SC-Resilience). The reliability scores of both I-PRRS and SCI subscales indicated good internal consistency. Correlation between the I-PRRS and the SCI ranged in magnitude from weak to moderately high. A similar trend of correlations was found between the subscales of the I-PRRS and the ITAMS, as well as between the subscales of the SCI and the ITAMS. Study findings showed satisfactory psychometric properties of the Italian version of the I-PRRS and SCI. •There is a growing interest in the assessment of psychological readiness of injured athletes using suitable instruments.•The I-PRRS scale and the SCI measure athletes’ confidence and can be used to evaluate their psychological readiness.•The reliability scores of both I-PRSS and SCI indicated good internal consistency.•CFA supported the two-factor structure of I-PRRS and three-factor structure of the SCI for the Italian version.
