German Translation and Content Validation of the Ostrc Questionnaire on Overuse Injuries and Health Problems

Abstract

BackgroundThe importance of a standardised injury and illness surveillance system in elite sports has recently often been highlighted. The OSTRC Questionnaire on Health Problems was developed and validated at the Oslo Sports Trauma Research Centre in Norway and showed very good validity.ObjectiveThe aim of this study was to translate, culturally adapt, and validate the Oslo Sports Trauma Research Centre Questionnaire on Health Problems into the German context.DesignA slightly modified back-translation method was used to translate the questionnaire. Validation was done in 24 high-level Paralympic athletes followed over 20 consecutive weeks.SettingWeb-based weekly distribution of the translated OSTRC questionnaire for 20 weeks.Patients (or Participants)24 athletes of the German National Cycling Team.Interventions (or Assessment of Risk Factors)None.Main Outcome Measurementsinternal consistency (Cronbach's Alpha) test-retest reliability (intraclass correlation coefficient), weekly response rate, lost training-days, Incidence of illness or injury.ResultsThe translated version of the questionnaire showed a very high internal consistency and good test-retest reliability (Cronbach's Alpha 0.92, ICC 0.91). Additionally, we observed high acceptance and compliance from our cohort of athletes, whose mean weekly response rate was 91.5%. Overall, 114 training-days were lost because of illness or injury within the 20 weeks. On average, five athletes per week (20.8%) reported health problems.ConclusionsThis study demonstrates that the translated German version of the OSTRC Questionnaire is a reliable and valid tool with high internal consistency for the medical monitoring of German athletes. The OSTRC-G now offers the opportunity for a continued surveillance of high-level German athletes.

Cross-Cultural Adaptation and Validation of the Oslo Sports Trauma Research Center Questionnaires on Overuse Injury and Health Problems (2nd Version) in Spanish Youth Sports

“…According to previous reports in other cultural adaptations, 10,13,14 a high test-retest reliability was found for the severity score. In addition, the high Cohen kappa indicated the high reliability of discriminative intention.…”

“…A high internal consistency was found according to the original instrument and the other published adaptations, 7,8,10,13,14 meaning that the items are interrelated and they measure consistently. 29 In this study, different subgroups were analyzed because the measurement properties can vary with the score distribution.…”

“…The need for these changes may be linked to the fact that our cohort was younger (age range, 12-18 years) than were those included in the original study and other cross-cultural adaptations, where the ages ranged from 18 to 55 years. 7,8,10,13,14 Otherwise, the improvements in the anatomic area description could prevent future misclassifications of self-reported injuries by athletes. Because a comprehensible Spanish version was achieved for young athletes, it is expected to also be comprehensible for adult athletes.…”

“…7,8 These questionnaires are used to identify athletes with health complaints (discriminative purpose) and to quantify the effect of these problems on the sport (evaluative purpose). Several language adaptations have been published, 10,13,14 and numerous studies and institutions have started to use these questionnaires for research and clinical practice. This situation suggests a shift in the method of sports epidemiology, relying first on a patient-reported outcome measure and assuming a definition of injury as “all complaints” instead of a time-loss approach based on an external observer.…”

Personalized machine learning approach to injury monitoring in elite volleyball players

“…Although the discretization of the OSTRC variables is a limitation, the OSTRC questionnaire is considered a valid method for investigating overuse injuries in sports (Gallagher et al, 2017). The method has been tested and validated in high-level athletes from different countries and sports (Charlton et al, 2017Clarsen et al, 2014Ekman et al, 2015;Hirschmüller et al, 2017;Jorgensen et al, 2016;Nagano et al, 2019), and captures the full development of overuse injuries. There is a high internal consistency (average Cronbach's α > 0.9), good test-retest reliability (intraclass correlation coefficient 0.62-0.91) and high construct validity (Ekman et al, 2015;Hirschmüller et al, 2017;Jorgensen et al, 2016).…”
