In this study, researchers implemented a short-term cascading coaching program focusing on naturalistic developmental behavioral interventions (NDBIs) with three participant triads consisting of a graduate student clinician, a minimally verbal child with autism spectrum disorder (ASD) or signs of ASD, and the child’s parent. The efficacy of several short-term instruction sessions, in-session coaching, and student clinician parent coaching was evaluated using a multiple baseline across interventionists design. The primary dependent variables were clinician and parent use of elicitation techniques, including creating communication temptations and prompting, and response techniques, including reinforcing child communication and using vocal models. Following targeting coaching, all three triads increased use of elicitation and response techniques for both parents and clinicians, though results for some triads were variable. Implications for successful use of NDBI strategies with student clinicians and parents and the short-term implementation of cascading coaching models for under-resourced or rural families are discussed.
