Cross-cultural adaptation and validation of the Injury-Psychological Readiness to Return to Sport scale to Persian language.

The aim of the present study was to develop and provide validation statistics for the Persian Injury-Psychological Readiness to Return to Sport scale (I-PRRS) following a cross-sectional and prospective cohort study design. The I-PRRS was forward/back-translated and culturally adapted into Persian language. The Persian I-PRRS was administered to 100 injured athletes (93 male; age 26.0 ± 5.6 years; time since injury 4.84 ± 6.4 months) and 50 healthy athletes (36 male; mean age 25.7 ± 6.0 years). The Persian I-PRRS was re-administered to 50 injured athletes at 1 week to examine test-retest reliability. There were no floor or ceiling effects confirming the content validity of Persian I-PRRS. The internal consistency reliability was good. Excellent test-retest reliability and agreement were demonstrated. The statistically significant difference in Persian I-PRRS total scores between the injured athletes and healthy athletes provides an evidence of discriminative validity. The Persian I-PRRS total scores were positively correlated with the Farsi Mood Scale (FARMS) total scores, showing construct validity. The principal component analysis indicated a two-factor solution consisting of "Confidence to play" and "Confidence in the injured body part and skill level". The Persian I-PRRS showed excellent reliability and validity and can be used to assess injured athletes' psychological readiness to return to sport among Persian-speaking populations.

Development and preliminary validation of the Injury-Psychological Readiness to Return to Sport (I-PRRS) scale.

CONTEXT: Only a few scales measure confidence within sport; however, these scales are insufficient to measure confidence after athletic injuries. Therefore, better measures are needed to determine the psychological readiness of injured athletes to return to sport participation. OBJECTIVE: To develop a scale that measures the psychological readiness of injured athletes to return to sport participation and to provide preliminary evidence of reliability and validity for the scale. DESIGN: The Delphi method was used to develop the Injury-Psychological Readiness to Return to Sport scale (I-PRRS). Two 1-way analyses of variance with repeated measures and 6 Pearson product moment correlations were computed to help validate the scale. SETTING: Athletic training clinics at 3 National Collegiate Athletic Association (NCAA) schools. PATIENTS OR OTHER PARTICIPANTS: Four certified athletic trainers (ATs) and professors of Commission on Accreditation of Athletic Training Education-accredited athletic training programs and 3 NCAA Division III coaches made up a panel of experts that participated in the Delphi portion of the study to develop the I-PRRS. In the second part of the study, 22 injured athletes, who missed a minimum of 1 week of practice, from 3 NCAA schools in Divisions II and III were surveyed along with their respective ATs. The injured athletes and ATs participated in the validation of the I-PRRS. MAIN OUTCOME MEASURE(S): The injured athlete completed the Profile of Mood States (POMS) short form and the I-PRRS shortly after injury, before returning to the first practice, before returning to competition, and immediately after competition. The respective AT completed the I-PRRS before and after competition. The I-PRRS is a 6-item scale that measures the psychological readiness of injured athletes to return to sport, and the POMS short form is a 30-item scale that measures mood states. I added the negative moods of the POMS and subtracted the positive moods of the POMS to calculate a Total Mood Disturbance (TMD) score. RESULTS: The I-PRRS scores were negatively correlated with the TMD scores of the POMS short form at all 4 time intervals, showing concurrent validity. The I-PRRS scores were lowest after injury, increased before practice, increased again before competition, and had no change after competition. The I-PRRS as completed by the athlete and respective AT was positively correlated both before and after practice, demonstrating external validity. CONCLUSIONS: Preliminary evidence for reliability and validity of the I-PRRS was demonstrated. The I-PRRS can be a beneficial tool for ATs to assess an athlete's psychological readiness to return to sport participation after injury.
