Early intervention for young children with autism spectrum disorder has historically been rooted within two distinct theoretical foundations: behavioral and developmental sciences. Proponents of each discipline have traditionally held opposing views toward treatment, with little collaboration. A recent shift in autism intervention has led to the emergence of a group of interventions that incorporate elements from both developmental and behavioral science. These naturalistic developmental behavioral interventions (NDBI) have been used effectively in a variety of settings with improvements in child and family outcomes. This symposium includes a series of presentations describing the application of naturalistic developmental behavioral interventions across a range of settings, with a focus on describing the integration of developmental and behavioral science in each. The first presentation will provide a broad overview of naturalistic developmental behavioral interventions, including a description of its core components. The second presentation will describe the implementation of naturalistic developmental behavioral interventions in a hospital-based clinic setting, including data related to the characteristics of children enrolled in the program. The third will describe child outcomes from a group-based delivery of naturalistic developmental behavioral intervention for preschool-aged children. The final presentation will shed light on the actual use of naturalistic developmental behavioral intervention strategies within community settings by describing the self-reported utilization of developmental and behavioral strategies from a large sample of applied behavior analysis providers.

Group-learning models for young children with autism provide environments rich with opportunities for teaching social communication and interaction skills. Comprehensive preschool programs that incorporate naturalistic developmental behavioral intervention (NDBI) strategies have produced improvements in children’s social communication skills, social engagement, and core ASD symptoms (Stahmer & Ingersoll, 2004; Strain & Bovey, 2011). This presentation will provide an overview of an NDBI treatment model delivered within a group program for preschool-aged children with autism. A description of the treatment model and subsequent changes in children’s social communication skills for 20 preschool-aged children enrolled in the program will be discussed. Staff fidelity was measured using a direct observation fidelity tool designed to measure the core components of a group-based NDBI model. Fidelity was high and averaged over 87% accuracy across all NDBI components. Changes in children’s social communication were measured at baseline and following six months of intervention using the Social Communication Checklist, a curriculum-based measure of social communication. Improvements were observed across all domains, with significant improvements in the group’s overall social communication score (p < .05), social engagement (p <.01), and play skills (p <.05). Implications for research and practice incorporating naturalistic developmental behavioral interventions into group-based treatment programs will be discussed.

Naturalistic developmental behavioral interventions (NDBIs; Schreibman et al., 2015) are a class of early interventions for autism spectrum disorder with growing empirical support, however, their similarity to Applied Behavior Analysis (ABA) as delivered in the community is unknown. This online survey-based study characterized the self-reported utilization of developmental and behavioral intervention techniques in a large sample of ABA providers (n=368) and explored what aspects of provider background predict utilization. Respondents rated the extent to which they used each of a number of intervention techniques in a recent session with a specific child. ABA providers self-reported less use of developmental techniques than behavioral techniques, t(356)=-26.35, p<0.001. Providers with greater self-reported competency in NDBIs reported more frequent use of developmental techniques (Table 1); NDBI competency was not related to use of behavioral techniques, which were reported at high levels across providers. Point-biserial correlations indicated some trending relationships with training background such that providers with a background in psychology reported greater use of developmental techniques and those with backgrounds in ABA and special education reported less use (Table 1). Results suggest that further research on the similarities and differences between NDBIs and ABA delivered in the community is warranted.
