Abstract

This study used a cascading coaching model to train bilingual speech-language pathology graduate students and Spanish-speaking caregivers to implement naturalistic developmental behavioral intervention (NDBI) strategies with autistic preschoolers. Two triads, each including a student clinician, minimally vocal child with autism, and caregiver, participated. A monolingual instructor coached student clinicians in culturally adapted NDBI techniques, who then coached caregivers in Spanish. A mixed methods approach evaluated outcomes through single-case experimental design and qualitative interviews. All adult participants increased their use of targeted NDBI skills, with large to very large effect sizes. Qualitative findings suggested areas for improvement (e.g., need for more Spanish resources) but also revealed positive impacts on adult learning, behavior, and perspectives; child communication; and caregiver-child relationships.
