A number of completed studies have demonstrated that ABA techniques can produce improvements in communication, social relationships, play, self care, school and employment. These studies involved age groups ranging from preschoolers to adults. Results for all age groups showed that ABA increased participation in family and community activities.
A number of peer-reviewed studies have examined the potential benefits of combining multiple ABA techniques into comprehensive, individualized and intensive early intervention programs for children with autism. “Comprehensive” refers to interventions that address a full range of life skills, from communication and sociability to self-care and readiness for school. “Early intervention” refers to programs designed to begin before age 4. “Intensive” refers to programs that total 25 to 40 hours per week for 1 to 3 years.
These programs allow children to learn and practice skills in both structured and unstructured situations. The “intensity” of these programs may be particularly important to replicate the thousands of interactions that typical toddlers experience each day while interacting with their parents and peers.
Such studies have demonstrated that many children with autism experience significant improvements in learning, reasoning, communication and adaptability when they participate in high-quality ABA programs. Some preschoolers who participate in early intensive ABA for two or more years acquire sufficient skills to participate in regular classrooms with little or no additional support. Other children learn many important skills, but still need additional educational support to succeed in a classroom.
