It's great you're looking into the long-term outcomes of ABA and ESDM! Both therapies show lasting improvements for children with autism. A recent study showed ESDM led to greater gains in social skills, while ABA excelled in gross motor skills.

ESDM's benefits, like increased IQ and better parent-child interactions, have been seen to last even with fewer therapy hours later on. High-intensity ABA (20-40 hours/week) is a strong predictor of mastering skills, especially in language and academics.
