Abstract
This study aimed to adapt and validate a pre-existing weight loss questionnaire specific for Olympic weightlifting (OWL) athletes, given their pre-competition body mass (BM) management practices are unknown. A structured four-phase validity process was employed, focusing on content, face validity, and internal reliability. The Delphi technique was applied utilising experts (n = 7) over three anonymous rounds to achieve consensus. Questions were reviewed to determine whether to keep, modify, or delete, then rate the relevance of each (content validity index (CVI)). Online interviews were conducted with a pilot group of OWL athletes (n = 6) to assess readability and item difficulty. A test-retest process was undertaken with a second pilot group (n = 9) to verify questionnaire reliability using Pearson’s correlation. All items in the first round achieved consensus with an item-CVI of 0.93, scale-CVI average of 0.98, and no items were recommended for deletion. The average difficulty rating was 4.8/5. Internal reliability was high for weight history (r = 0.93) and weight loss methods (r = 0.83), and moderate for influences (r = 0.65). The adapted questionnaire was shown to be a valid tool for content and face validity to assess the BM management practices of OWL athletes.
