The Functional Disability Inventory (FDI) is a well-established and commonly used measure of physical functioning and disability in youth with @entity1118 . Further validation of the measure has been called for, in particular, examination of the clinical utility and factor structure of the measure. To address this need, we utilized a large multicenter dataset of pediatric @entity1 with @entity1118 who had completed the FDI and other measures assessing @entity158 and emotional functioning. Clinical reference points to allow for interpretation of raw scores were developed to enhance clinical utility of the measure, and exploratory factor analysis was performed to examine its factor structure. @entity1 included 1300 youth ages 8 to 18 years (mean=14.2 years; 76% female) with @entity1118 . Examination of the distribution of FDI scores and validation with measures of @entity308 and @entity158 intensity yielded 3 distinct categories of disability: No/Minimal Disability, Moderate Disability, and Severe Disability. Factor analysis of FDI scores revealed a 2-factor solution representing vigorous Physical Activities and non-physically strenuous Daily Activities. The 3-level classification system and factor structure were further explored via comparison across the 4 most commonly encountered @entity158 conditions in clinical settings (head, back, abdominal, and @entity158 ). Our findings provide important new information regarding the clinical utility and validity of the FDI. This will greatly enhance the interpretability of scores for research and clinical use in a wide range of @entity158 conditions. In particular, these findings will facilitate use of the FDI as an outcome measure in future clinical trials.
