How many hours a week of intervention do young children with autism need? A new study suggests that the precise number may not be all that consequential.
Researchers say they found similar outcomes in toddlers with autism whether they participated in 15 or 25 hours each week of one-on-one intervention.
Ultimately, the study found no meaningful difference in the level of progress in receptive language, expressive communication, nonverbal ability or autism symptoms across the four different treatment groups. That was the case even when comparing children with varying levels of severity at the outset, the researchers said.
