¹Adult kappas are provided to allow comparison of results within each domain (although tests included within a domain may have differed by age group).

²Bolded kappas indicate discrimination between the control and autism group for that age group.

³The direct entry method was used for this domain allowing for the production of a classification table and computation of kappa.
