A recent study of Special Olympics Unified Sports in Serbia, Poland, Ukraine, Germany and Hungary documented the benefits of Unified Sports, including the effect of changing attitudes toward people with intellectual disabilities. As one Unified Sports partner said, "I am ashamed to say that I used to laugh at these people (people with intellectual disabilities), now I will tell anybody to stop laughing if I see it and I will stand up for people if I can." Other evaluations have also shown Unified Sports to be successful in building self-esteem and confidence in people with intellectual disabilities and also as a way to improve understanding and acceptance of people with intellectual disabilities among their non-disabled peers.
