Intervention targeting development of socially synchronous engagement in toddlers with autism spectrum disorder: a randomized controlled trial - Landa - 2010 - Journal of Child Psychology and Psychiatry - Wiley Online Library: A significant treatment effect was found for socially engaged imitation (p = .02), with more than doubling (17% to 42%) of imitated acts paired with eye contact in the Interpersonal Synchrony group after the intervention. This skill was generalized to unfamiliar contexts and maintained through follow-up. Similar gains were observed for initiation of joint attention and shared positive affect, but between-group differences did not reach statistical significance. A significant time effect was found for all outcomes (p < .001); greatest change occurred during the intervention period, particularly in the Interpersonal Synchrony group.
