The Turkish Version of the OSTRC Questionnaires

Exposure to repetitive activities and heavy workloads makes athletes vulnerable to overuse injuries over time. Well-timed detection of these injuries is crucial to maintaining their sports career healthily. The Oslo Sports Trauma Research Centre questionnaires for Overuse Injury (OSTRC-O) and Health Problems (OSTRC-H) are universally used as valid and reliable tools in athlete health screening. This study aims to make them available for Turkish athletes. The internal consistency, reproducibility, and validity of the questionnaires were analyzed. Data were obtained from 72 athletes from different sports types. 33 participants were screened weekly for six weeks to detect score changes and calculate effect sizes. Participants filled out the OSTRC-O, the OSTRC-H, the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), and the Nottingham Health Profile (NHP) for validity analyses. The internal consistency and test-retest reliability values were very high for both questionnaires. There was a moderate correlation between OSTRC-O and OSTRC-H scores with CMDQ and NHP. The area under the curve (AUC) values were adequate for all scales. The effect size values were moderate for all scales. Turkish versions of the OSTRC-O and OSTRC-H questionnaires are valid and reliable tools for Turkish-speaking athletes in different sports branches.
