Developing and Validating the Risk-taking Intention and Sport Engagement After ACL Reconstruction (RISE-ACL) Scale

A meeting will be organized with all expert panel members to select relevant items. Before the meeting, experts will review a literature on ACL reconstruction return to sport processes. During round 1, the chairperson will ask panel members to suggest items to be included in the scale. Items with agreement from 5 or more members will be included in round 2. In round 2, redundant items will be identified and grouped, and new items will be added based on the literature and expert experience. Selected items will be randomly ordered to create a preliminary 6-level Likert scale (0 = strongly disagree, 5 = strongly agree).

"The scale validation phase will involve 162 participants who have undergone ACL reconstruction within the past two years and are in the 'Return to Sport' process, with follow-up in the sports medicine department.~These participants will complete the final version of the RISE-ACL Scale in addition with the ACL-RSI scale and the IKDC Subjective Knee Form.~Validation will consist of testing face validity, construct validity, criterion validity (concurrent validity), and reliability, including internal consistency and test-retest reliability."
