C. Gillberg et al., The Asperger Syndrome (and high-functioning autism) - Diagnostic Interview(ASDI): a preliminary study of a new structured clinical interview, AUTISM, 5(1), 2001, pp. 57-66
The development of the Asperger Syndrome (and high-functioning autism) Diag
nostic Interview (ASDI) is described. Preliminary data from a clinical stud
y suggest that inter-rater reliability and test-retest stability may be exc
ellent, with kappas exceeding 0.90 in both instances. The validity appears
to be relatively good. No attempt was made in the present study to validate
the instrument as regards the distinction between Asperger syndrome and hi
gh-functioning autism.
