aEvaluated in 82 participants (full-scale intelligence quotient (FSIQ) ≥50).
bMattila et al.'s modification of DSM-5 draft criteria [18].
cIncluding autism, Asperger's syndrome (AS), and “the rest.”
dAccording to parents' developmental questionnaire and patient records (one with AS and one with AS traits).
eOf all autism spectrum disorders (ASDs), 65% high-functioning.
fBased on screening and examinations in the epidemiological study.
gDrawn from patient records (three with autism, five with autistic traits, and one with pervasive developmental disorder).
