Preschool Teachers' Perceptions and Use of Naturalistic Developmental Behavioral Intervention Strategies: An Explanatory Sequential Mixed Methods Investigation.

Preschool classrooms serve children of varying abilities, including those who may benefit from social communication intervention. Research supports the use of naturalistic developmental behavioral interventions (NDBI) to effectively increase social communication skills of young children. Yet, little is known about preschool teachers' perspectives on and use of NDBI strategies. The purpose of this explanatory sequential mixed methods study was to integrate data from classroom observation, teacher self-report, and qualitative interviews to understand training and support needs for increasing implementation of NDBIs in a preschool classroom context. Eight preschool teachers provided a recording of an intervention session, self-reported their use of NDBI strategies, and participated in an interview to discuss their experiences. Results indicate preschool teacher participants perceive NDBI strategies favorably, although they may need targeted support understanding and using NDBI strategies. We discuss implications for practice that may support increased use of NDBIs by preschool teachers.
