Low intensity behavioral treatment supplementing preschool services for young children with autism spectrum disorders and severe to mild intellectual disability.
This study evaluated the effectiveness of low intensity behavioral treatment ( on average 6.5h per week ) supplementing preschool services in 3 - 6-year-old children with autism spectrum disorder and severe to mild intellectual disability . Treatment was implemented in preschools ( i.e. , daycare centers ) and a discrete trial teaching approach was used . Twelve children in the treatment group were compared to 22 children receiving regular intervention .  At pre-treatment , both groups did not differ on chronological age , developmental age , diagnosis and level of adaptive skills . Eight months into treatment , children receiving behavioral treatment displayed significantly higher developmental ages and made more gains in adaptive skills than children from the control group . No significant differences between groups were found on autistic symptom severity and emotional and behavioral problems
