Abstract
Psychometric properties of the Autism Survey, an instrument designed to assess respondents' knowledge about autism, were evaluated. Subjects completed the survey at a training conference and again 1 month later. Confirmatory factor analysis indicated that the survey measures one factor. With respect to reliability, the Autism Survey proved to be stable across time, and the total score was internally consistent. A few rogue items were recommended for deletion. Further analyses support the validity of the instrument.
