OBJECTIVES: The purpose of this study was to cross-culturally validate in the Italian language the I-PRRS and the SCI.
DESIGN: Cross-sectional study. SETTING: Injured Italian athletes. PARTICIPANTS: We recruited male (n = 73) and female (n = 27) athletes who returned to practice after having completed the rehabilitation. MAIN OUTCOME MEASURES: 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.
RESULTS: 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.
CONCLUSIONS: Study findings showed satisfactory psychometric properties of the Italian version of the I-PRRS and SCI.
