Abstract: While numerous questionnaires have been developed to investigate injuries in athletes across various sports, a significant void exists in the literature regarding a questionnaire that specifically assesses injury prevalence, frequency, and severity in recreational marathon runners, highlighting the need for a targeted and validated tool. Therefore, this comprehensive study was envisaged to develop and validate a questionnaire which can be used in any long distance runner. Questionnaire was constructed in two phases: 1. questionnaire development and 2. validity assessment & pilot testing. Questionnaire was developed after thorough critical review of relevant articles. Once the questionnaire was developed primary content validation was done by 2 experts of the field. Based on the suggestions of the experts revision was done in the questionnaire. This was followed by face validation from 2 runners of target population. After receiving the responses from runners Delphi blinded validation was done to get reviews from external blinded reviewers. After Delphi validation pilot fill-up was done from 2 participants of target population and at last item level content validity index (I-CVI) and scale-level content validity index (S-CVI/Ave) values were calculated to get quantitative detail of the questionnaire validity. The calculated score CVI value was 0.9629 which suggested excellent content validity. Delphi facilitator had also received positive reviews from the reviewers. In conclusion the questionnaire was found to be a valid measure for determining injury prevalence, frequency & severity in recreational marathon runners.
