Validation of the Inventory of Teaching Challenges for Inclusive Physical Education: Autism Spectrum Disorders

The study developed and provided evidence of content validity, internal consistency, and factor structure of the Inventory
of Teaching Challenges for Inclusive Physical Education (ITC-IPE) with children with autism spectrum disorders. Content validity
of the ITC-IPE was established by seven content experts. A background questionnaire and the ITC-IPE were administered to two
samples: a pilot sample of 220 certified physical educators and a validation sample of 253 certified physical educators. Teachers
rated teaching challenges using a difficulty scale and a frequency scale. Findings revealed four factors (task-related challenges,
social behavior challenges, environmental challenges, and challenges related to narrow interest and inflexibility), which
explained 60% of the variance for both scales. Internal consistency ranged between .88 and .94. All factors were inter-correlated.
