Research Studies

Lovaas (1987) - The seminal study that demonstrated the efficacy of Early, Intensive Behavior Intervention (EIBI) for children with autism. This study "showed that 47% [of children receiving EIBI] achieved normal intellectual and education functioning, with normal-range IQ scores and successful first grade performance in public schools."

Howard et. al. (2005) - This study found that, consistent with previous research, intensive (25-40 hours) ABA "is considerably more efficacious than “eclectic” intervention."

Sallows & Graupner (2005) - One of the most recent replications of the original study. This study "found that 48% of all children [who received intensive behavioral treatment] showed rapid learning, achieved average post-treatment scores, and at age 7, were succeeding in regular education classrooms. Treatment outcome was best predicted by pretreatment imitation, language, and social responsiveness."
