The O slo S ports T rauma R esearch C entre O veruse Injury Questionnaire ( OSTRC ‐ O ) and the O slo S ports T rauma R esearch C entre questionnaire on Health Problems (The OSTRC ‐ H ) make it possible to monitor illness and injury at regular intervals capturing prevalence and incidence of acute injury, overuse injury, and illnesses. The aim of this study was to translate, culturally adapt, and establish the face validity of the OSTRC ‐ O and the OSTRC ‐ H into a D anish context ( DK ) through cognitive interviews and the assessment of test–retest reliability. The OSTRC ‐ O . DK was distributed to 57 heterogenous respondents; response rate was 89%. The OSTRC ‐ H was distributed to 58 heterogenous respondents; response rate was 86%. No major disagreements were observed between the original and translated versions of the questionnaires. The OSTRC ‐ O had high internal consistency ( C ronbach's alpha 0.80–0.93). The primary reliability analyses including all participants, showed reliability ICC : 0.62 (95% CI : 0.42–0.77. The secondary reliability analyses that only included subjects who did not change injury region from the test to the retest showed an ICC of 0.86 (95% CI : 0.77–0.92).The questionnaires were found to be valid, reliable, and acceptable for use in a D anish population.
