Dg. Campbell et al., THE AUTISM SURVEY - AN EVALUATION OF RELIABILITY AND VALIDITY, Journal of autism and developmental disorders, 26(6), 1996, pp. 621-634
Psychometric properties of the Autism Survey, an instrument designed t
o assess respondents' knowledge about autism, were evaluated. Subjects
completed the survey at a training conference and again I month later
Confirmatory factor analysis indicated that the survey measures one f
actor. With respect to reliability, the Autism Survey proved to be sta
ble across time, and the total score was internally consistent. A few
rogue items were recommended for deletion. Further analyses support th
e validity of the instrument.
