Professionals who primarily deliver services to children on the autism spectrum employ a range of techniques and supports that are colloquially known as applied behavior analysis therapy. The landscape of evidence supporting interventions for children on the autism spectrum has vastly transformed in the last decade. A substantial, relatively high-quality literature base supports the effectiveness of Naturalistic Developmental Behavior Interventions for supporting development in children on the autism spectrum, yet few professionals serving this population receive training in this category of interventions. Board Certified Behavior Analysts and related professionals are the primary service providers for this population. The purpose of this survey study is to describe and understand the knowledge and beliefs that Behavior Analyst Certification Board certificants have around Naturalistic Developmental Behavior Interventions, and the implications for training the professionals most likely to serve young children on the autism spectrum. A total of 901 respondents completed the survey. Respondents indicated, on average, little to no knowledge of Naturalistic Developmental Behavior Intervention practices and that few believe these practices to be effective or appropriate for the field. We discuss the implications and needs for future training and research in this area.

Lay abstract

Primary service providers for young children on the autism spectrum and developmentally delayed children use many strategies under the umbrella of applied behavior analysis therapy. The evidence supporting interventions for children on the autism spectrum has changed last decade, and powerful research supports the relative effectiveness of Naturalistic Developmental Behavior Interventions, yet a few professionals serving young children on the autism spectrum receive training in this category of interventions. Board Certified Behavior Analysts and related professionals are the primary service providers for this population. The purpose of this survey study is to describe and understand the knowledge and beliefs that Behavior Analyst Certification Board certificants have around Naturalistic Developmental Behavior Interventions. The survey was completed by 901 respondents. Respondents indicated, on average, little to no knowledge of Naturalistic Developmental Behavior Intervention practices and few believe that these practices are effective or appropriate for the field. Recommendations include increasing training opportunities for related professionals, and changing certification requirements to match the current evidence.
