Randomized comparison of two communication interventions for preschoolers with autism spectrum disorders.
This r and omized group experiment compared the efficacy of 2 communication interventions ( Responsive Education and Prelinguistic Milieu Teaching [ RPMT ] and the Picture Exchange Communication System [ PECS ] ) in 36 preschoolers with autism spectrum disorders . Each treatment was delivered 3 times per week , in 20-min sessions , for 6 months . The results revealed that the RPMT facilitated the frequency of generalized turn taking and generalized initiating joint attention more than did the PECS . The latter effect occurred only for children who began treatment with at least some initiating joint attention . In contrast , the PECS facilitated generalized requests more than the RPMT in children with very little initiating joint attention prior to treatment . These effect sizes were large
