Results are comparable with several other studies with a similar or slightly higher therapeutic intensity implementing comparable or different early intervention methods or programs .
Compared to most high-intensity programs ( 30–40 h/week ) , lower cognitive gains were observed .
Different early intervention programs , developed predominantly in the US , for preschool aged children with autism spectrum disorders ( ASD ) have been published .
Several systematic review articles including a German Health Technology Assessment on behavioural and skill-based early interventions in children with ASD reported insufficient evidence and a substantial problem of generalisability to the German context .
In Germany , approx .
2–5 h early intervention is supported by social services .
Cognitive and Adaptive Behavior Outcomes of Behavioral Intervention for Young Children With Intellectual Disability
Data from Norway were analyzed to evaluate early behavioral intervention for children with intellectual disabilities . The intervention group ( n = 11 ) received approximately 10 hours per week of behavioral intervention ; the eclectic comparison group ( n = 14 )  received treatment as usual . After 1 year , changes in intelligence and adaptive behavior scores were statistically significant in favor of the behavioral intervention group ( effect sizes of 1.13 for Intelligence quotient ( IQ ) change and .95 for change in adaptive behavior composite ) . Approximately 64 % of the children in the behavioral intervention group met objective criteria for reliable change in IQ , whereas 14 % in the eclectic comparison group did so . These results suggest that children with intellectual disability may profit from behavioral intervention typically provided for children with autism
