The current study sought to evaluate the effectiveness of an Australian centre-based early intervention program
for children with autism. Outcomes for 10 children with autistic disorder aged between 32 and 65 months of age
participating in the AEIOU early intervention program were investigated. Measures of educational, cognitive, and
adaptive skills as well as autism symptoms were administered. Significant gains in educational skills in the areas of
cognitive verbal/preverbal, fine motor and visual-motor imitation, motor domain score, and social reciprocity, were
obtained as were decreases in autism symptoms. Limited evidence of gains was obtained for measures of cognitive or
adaptive behaviour skills. This study provides promising preliminary evidence in support of the AEIOU program in terms
of symptom reduction and increases in educational skills. Limitations and future research directions are discussed.
