A randomized controlled trial of preschool-based joint attention intervention for children with autism.
BACKGROUND Deficits in joint attention ( JA ) and joint engagement ( JE ) represent a core problem in young children with autism as these affect language and social development . Studies of parent-mediated and specialist-mediated JA-intervention suggest that such intervention may be effective . However , there is little knowledge about the success of the intervention when done in preschools . AIM Assess the effects of a preschool-based JA-intervention . METHODS 61 children ( 48 males ) with autistic disorder ( 29 - 60 months ) were r and omized to either 8 weeks of JA-intervention  , in addition to their preschool programs  ( n = 34 ) , or to preschool programs only  ( n = 27 ) . The intervention was done by preschool teachers with weekly supervision by trained counselors from Child and Adolescent Mental Health Clinics ( CAMHC ) . Changes in JA and JE were measured by blinded independent testers using Early Social Communication Scale ( ESCS ) and video taped preschool teacher-child and mother-child play at baseline and post-intervention . CLINICAL TRIALS REGISTRATION Clinical trials.gov : NCT00378157 . RESULTS Intention-to-treat analysis showed significant difference between the intervention and the control group , with the intervention group yielding more JA initiation during interaction with the preschool teachers . The effect generalized to significantly longer duration of JE with the mothers . CONCLUSIONS This is the first r and omized study to show positive and generalized effects of preschool-based JA-intervention
