Pivotal response treatment for preschoolers with autism spectrum disorder: Defining a predictor profile.

The study examined behavior of 57 preschoolers who made the greatest and least gains from 1 year of a community Pivotal Response Treatment program. Using pre-treatment videos, we saw that children who made the most progress showed more language, positive affect, and appropriate interactions with toys, also less avoidance of people and fewer repetitive vocalizations. Behavior profiles can be used to match treatment to individual children's needs.
