Background: Schoolboys (N = 156, M age = 13 years) participated in a disability awareness training program that included guest speakers (athletes from the Paralympics and the Special Olympics), a documentary about people with a disability, a disability simulation activity, and factual information about different disabilities. Method: Participants were allocated to a training program or a control condition. Subsequently, control participants completed the training program. Attitudes toward disability were measured by the Chedoke-McMaster Attitudes Towards Children With Handicaps (CATCH) Scale and the scale from the "Just Like You" disability awareness intervention, before and after training. Results: Training improved attitude scores, and gains were retained at one-month follow-up. Conclusions: Disability awareness training that delivered relevant information by involving guest speakers with a disability, included documentary evidence about the lives of people with a disability, and included interactive discussion, was successful. CATCH and "Just Like You" are useful tools for measuring self-reported attitudes about disability.
