“Researchers at the Center for Autism and Related Disorders, Inc. (CARD) found that increasing treatment hours within an early intensive behavioral intervention program resulted in greater efficiency in new skill acquisition. This effect was the strongest in younger children within their study.
The study also showed no point of diminishing returns as hours were increased. Meaning that 20 hours per week was better than 10, 30 hours per week was better than 20, and 40 was better than 30. The degree of improvement did not decrease as treatment intensity approached 40 hours per week.”
