Although attitudes of sports participants relate significantly to the successful inclusion of individuals with disabilities in regular sport programs, there has been no published research on attitudes toward inclusion or rule modifications. We examined attitudes of girls without disabilities, their parents, and their coaches towards inclusion of a child with disabilities in a regular girls' fast-pitch softball league. They completed the Attitudes Towards Integrated Sports Inventory prior to the season. Results suggest that players and parents had a favorable attitude towards inclusion and towards modifying the game rules to enable this player to have a safe, successful experience. Coaches were undecided about inclusion and rule modifications.
