Inclusive Preschool Practitioners' Implementation of Naturalistic Developmental Behavioral Intervention Using Telehealth Training

This single-case investigation was designed to evaluate the effects of telehealth training on practitioner implementation of a naturalistic developmental behavioral intervention (NDBI). Six general education preschool practitioners engaged in an intervention with six children with varying disabilities in inclusive classroom settings. The telehealth training package included a collaborative approach to intervention planning, online training module, video self-evaluation, and performance feedback via videoconferencing. Following telehealth training, practitioners reached criteria for implementation fidelity and increased communication opportunities. Additionally, child participants increased communication behaviors above baseline levels. All behaviors generalized to a different activity context and maintained over time. Social validity was measured and results suggest high levels of acceptability for the telehealth training package.
