In the Lovaas (1987) study, what percentage of participants achieved recovery?

The Lovaas (1987) study, which is a landmark research in applied behavior analysis (ABA) and autism treatment, found that approximately 47% of the participants achieved what was defined as "recovery." This refers to a significant improvement in functioning and behavior, where individuals were able to be mainstreamed into regular education settings without the need for special education services.

The study's findings emphasized the effectiveness of intensive early intervention, showcasing that behaviors associated with autism can be modified and that many individuals with autism spectrum disorder can make substantial progress in their development. The percentage of 47% reflects the success of the treatment methods employed in the research, illustrating that a meaningful proportion of the children demonstrated significant improvements in their skills and behaviors after receiving ABA therapy.
