Purpose: The authors investigated perceived exercise and physical activity barriers of active youth with physical disabilities. Research Method/Design: A 46-item exercise barrier instrument was administered to 145 youth (117 boys and 28 girls, 12 to 19 years of age). Using the Rasch model, the authors estimated barrier severity and youths' exercise perseverance. Model-data fit was determined by Infit and Outfit statistics (≥ 0.5 and ≤ 1.5). Results: Except for 1 item, the model fit the data well. The most difficult barriers that youth with physical disabilities faced were lack of time and pain or discomfort. The older youth demonstrated higher exercise perseverance than the younger youth. There were no differences in youths' exercise perseverance scores by gender or National Wheelchair Basketball Association classification. Implications: Removing severe barriers should be a part of future exercise and physical activity interventions targeting this population.
