The effects of age and treatment intensity on behavioral intervention outcomes for children with autism spectrum disorders.
Granspeesheh and colleagues has investigated the effect of age and treatment intensity on the rate of learning within an early intensive behavioral intervention (EIBI) program fro children with autism spectrum disorders (ASD). Their study includet 245 children, a greater number than several other studies in the intervention research for children with ASD.
This study indicates several important aspects of the influence of age en treatment intensity; the data indicates that the youngest children showed the greatest effect at low levels of intensity – similar gains as the middle aged group at high levels of intensity. And in the oldest group the data did not show a relationship between the number of objectives mastered and treatment intensity.
The date did not indicate a point of diminishing-returns – a point where more hours do not have more effect.
