Background:
Exposure to repetitive activities and heavy workloads makes athletes vulnerable to overuse injuries in 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. We aimed to make them available to Turkish athletes and assess their psychometric properties.
Methods:
The questionnaires were adapted to Turkish based on systematic guidelines. Seventy-two athletes were recruited from various sports branches. The internal consistency, reproducibility, and validity of the questionnaires were checked. Their total scores were compared with the scores of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and the Nottingham Health Profile (NHP) for concurrent validity. Thirty-three participants were screened for six weeks to detect score changes and calculate effect sizes.
Results:
The Cronbach alpha values of the OSTRC-O and OSTRC-H were very high (.90 and .91, respectively). Test-retest reliability was excellent for both questionnaires (.98, p<.01). There was a moderate correlation between OSTRC-O and OSTRC-H scores with CMDQ and NHP (p<.01). The area under the curve (AUC) values were higher than .70 for all scales. The effect size values were moderate for all scales.
Conclusions:
Turkish versions of the OSTRC-O and OSTRC-H questionnaires are valid and reliable tools for Turkish-speaking athletes in different sports branches.
