Wl. Stone et Kl. Hogan, A STRUCTURED PARENT INTERVIEW FOR IDENTIFYING YOUNG-CHILDREN WITH AUTISM, Journal of autism and developmental disorders, 23(4), 1993, pp. 639-652
This study evaluated the psychometric properties of the Parent Intervi
ew for Autism (PIA), a structured interview for gathering diagnostic i
nformation from parents of young children with autism. Internal consis
tency was evaluated in a sample of 165 children under 6 years old, and
test-retest reliability and construct validity were evaluated in subs
amples of the original group. Results revealed internal consistency an
d test-retest reliability above .60 for 9 of the 11 dimensions constit
uting the PIA, as well as significant correlations between the PIA and
other measures of autism. Six of the PIA dimensions differentiated a
group of young children with autism from a developmentally comparable
group with mental retardation. Implications of these findings and sugg
estions for future research am discussed.
