Brief Report: Pilot Randomized Controlled Trial of Reciprocal Imitation Training for Teaching Elicited and Spontaneous Imitation to Children with Autism
Children with autism exhibit significant deficits in imitation skills .  Reciprocal Imitation Training ( RIT ) , a naturalistic imitation intervention , was developed to teach young children with autism to imitate during play . This study used a r and omized controlled trial to evaluate the efficacy of RIT on elicited and spontaneous imitation skills in 21 young children with autism . Results found that children in the treatment group made significantly more gains in elicited and spontaneous imitation , replicating previous single-subject design studies . Number of spontaneous play acts at pre-treatment was related to improvements in imitation during the intervention , suggesting that children with a greater play repertoire make greater gains during RIT
