Background: Reducing injury and health problems related to youth sports participation is a challenge for people involved in athlete´s well-being, due to the increasing demands over the athletes and their potential detrimental effects over their growing, health status and career development. To implement comprehensive injury prevention programs is necessary to know the epidemiology, but the real impact of overuse injuries remains unknown due to methodological limitations of traditional registration methods. The Oslo Sports Trauma Research Center Questionnaires on health problems (OSTRC-H) and overuse injuries (OSTRC-O) were developed to follow the health status of the athletes during the season. These questionnaires are employed to calculate a severity score and to detect health problems, reporting higher rates of overuse problems when compared to traditional methods. Despite of their increasing use in youth sports studies, it remains unknown their psychometric properties in this population and no Spanish version has been reported.
Purpose: To cross-culturally adapt and investigate the psychometric properties of the OSTRC-O (knee, shoulder and lower back) and OSTRC-H questionnaires for Spanish youth sports population.
Methods: Transcultural adaptation of the questionnaires was conducted following international guidelines (including forward and backtranslations, Expert Committee review and comprehensibility analysis with 30 athletes). An update of the English questionnaires was employed, following the recommendation of the original author. Psychometric testing of the Spanish version was done following the recommendations of the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN). Athletes between 12 and 18 years old from the M-86 Regional High-Performance Centre (swimming, water polo, artistic swimming and triathlon teams) (Madrid, Spain) were invited to participate. During 10 consecutive Sundays, a mobile message was sent to the athletes with a link to the questionnaires. Test-retest analysis was performed in a time-frame of 48-72h. A final survey was sent asking about content relevance, comprehensiveness and other impressions about the method.
Results: After some changes in the introduction and answers due to common comprehensibility problems, a final equivalent Spanish version was achieved. Sixty-three athletes (38 women) participated in the psychometric testing (mean age 15 years, range 12-17 years). The response rate for OSTRC-O questionnaire was 95,5%, while for OSTRC-H 98,6%. Cronbach´s alpha was 0,92 for OSTRC-H and 0,91 for OSTRC-O. The intraclass correlation coefficient was 0,88 (OSTRC-H) and 0,85 (OSTRC-O). Correlations between severity score in OSTRC-H and time-loss (Spearman´s Rho=0,60) and between change in both scores over time (Spearman´s Rho=0,66) were in the expected range. No significant floor or ceiling effects were observed during the 10 weeks ( 15%).
Conclusion(s): This study shows a content equivalent, valid and reliable Spanish version of OSTRC-O and OSTRC-H questionnaires when applied to a youth sports population. However, psychometric testing is a process of accumulated evidence and more is necessary to know about their psychometric properties to fully understand their scores.
Implications: High adherence, the ease of administration and scoring, the good psychometric properties showed and the lack of availability of similar tools in Spanish makes this surveillance system a key instrument for health monitoring in clinical practice and research in Spanish young athletes.
