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

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.
