%X DESIGN: Delphi panel and cohort study. <br><br>OBJECTIVE Develop and refine a condition-specific patient reported outcome known as the Ankle-Fracture Outcome of Rehabilitation Measure (A-FORM); and examine its psychometric properties including factor structure, reliability, and validity by assessing item fit with the Rasch model. Background To our knowledge, there is no ankle-fracture specific patient reported outcome with robust content foundation. <br><br>METHODS A 2 stage research design was implemented. First, a Delphi panel including patients and health professionals was used for item development and wording refinement. Second, a cohort study (n=45) with 2 assessment points was undertaken to permit preliminary maximum likelihood exploratory factor analysis then Rasch analysis. <br><br>RESULTS The Delphi panel reached consensus on 53 potential items that were carried forward to the cohort phase. From the 2 time-points, 81 questionnaires were completed and analyzed; 38 potential items were eliminated on account of greater than 10% missing data, factor loadings, and uniqueness. The 15 unidimensional items retained in the scale demonstrated appropriate person and item reliability after (and before) removal of 1 item (anxious about footwear) that had a higher than ideal outfit statistic (1.75). The anxious about footwear item was retained in the instrument but only the 14 items with acceptable infit and outfit statistics (0.5-1.5 range) contribute to the summary score. <br><br>CONCLUSIONS This investigation developed and refined the A-FORM (Version 1.0). The A-FORM items demonstrated favorable psychometric properties and are suitable for conversion to a single summary score. Further studies utilizing the A-FORM instrument are warranted.
