Scoring and Interpretation
Results consist of a total score between 0 and 54, where higher scores indicate that many characteristics of ASD were reported. A score of 13 and above indicates ASD is probable, with a true positive rate of 90% and a false positive rate of 22% (Ehlers, Gillberg, Wing, 1999).
In addition, a percentile based on Ebler, Gillberg and Wing (1999) sample of ASD children is presented. A percentile of around 50 would indicate that this individual scored at a similar level to the validation sample who were independently diagnosed with ASD (DSM-IV Aspergers). A percentile of 4.9 corresponds to the the cutoff raw score of 13.
