Addressing disruptive behaviors within naturalistic developmental behavioral interventions: Clinical decision-making, intervention outcomes, and implications for practice.

LAY ABSTRACT: Naturalistic developmental behavioral interventions are a common and well-researched type of intervention for young autistic children that focus on supporting social communication. These interventions often do not include formal guidelines on how to address disruptive behaviors, even though they are common among autistic children. This study measured how often clinicians delivering a specific naturalistic developmental behavioral intervention, Project ImPACT, adapted how they delivered the program to address disruptive behavior, and how these adaptations related to children's social communication outcomes at the end of their participation in the intervention. We also spoke with clinicians about how they address disruptive behavior and emotion regulation during their sessions. In this study, clinicians adapted Project ImPACT to address disruptive behaviors in about one-third of all sessions. These adaptations did not affect children's social communication outcomes. Clinicians discussed how they felt social communication, disruptive behavior, and emotion regulation are linked to one another and that they often try to integrate intervention strategies to address each of these areas. However, they note that a clinicians' approach to addressing disruptive behavior might vary depending on their level of training and experience. These results indicate several future directions for supporting clinicians in addressing behavior and regulation effectively within these types of interventions.

Examining provider decisions around the delivery and adaptation of a parent-mediated intervention within an Early Intervention system.

LAY ABSTRACT: Parent-mediated interventions are an evidence-based practice for autism in which providers support caregivers in learning and applying strategies that support their child's development. Research has begun to study whether parent-mediated interventions can be effectively delivered in Part C Early Intervention systems. This research has been promising; however, it has been difficult to determine how Early Intervention providers deliver and adapt parent-mediated interventions to meet the needs of the families they serve. Examining how parent-mediated interventions are delivered and adapted may help us understand whether parent-mediated interventions are a good fit in these systems. The current study examined the delivery of an evidence-based parent-mediated intervention, Project ImPACT, when delivered by providers within an Early Intervention system. Results from 24 Early Intervention providers demonstrated that, on average, providers delivered Project ImPACT with higher quality during their time in training and consultation. However, there was also variability in how providers delivered Project ImPACT, with some delivering the program inconsistently, some increasing their quality throughout consultation, and others having consistently high-quality delivery. In addition, qualitative data demonstrated that a variety of events arose within Project ImPACT sessions that drove providers to adapt the program. Results suggest the importance of carefully examining how and why providers deliver evidence-based interventions within Early Intervention systems.
