Abstract
Rationale: Few communication interventions for Latino Spanish-speaking (LSS) families with young children with language impairments and autism have been experimentally tested. EMT en Español is a culturally and linguistically adapted language intervention that has been effectively implemented by LSS caregivers of children with developmental language disorders. It has not yet been tested with families of children with autism who use augmentative and alternative communication (AAC). Method: Four LSS caregivers enrolled in the current study. Two caregivers completed the study and were taught to implement EMT en Español Para Autismo with their toddlers with autism who used AAC using the teach-model-coach-review approach. The intervention built upon EMT en Español research and was individualized for each family. The design was a multiple baseline across behaviors single case experimental design. The primary dependent variable was the caregivers’ implementation of the intervention strategies. Secondary dependent variables were caregiver fidelity, child social communication, and generalization of strategy use. Social validity data was gathered from interviews and summarized. Dosage was explored. Results: Caregivers used EMT en Español Para Autismo strategies when taught using the teach-model-coach-review approach and generalized use of some strategies to unsupported interactions. Caregiver fidelity increased gradually over time. Child communication using AAC increased in frequency and diversity. Caregivers were satisfied with the program and noticed their child’s emotions and communication. Caregivers also had difficult with some aspects, including use of speech generating devices. Dosage differed slightly across dyads. Conclusion: The current study provides preliminary evidence supporting a culturally and linguistically adapted AAC intervention for an underserved and understudied population. More research is needed testing the intervention with additional families.
