Just-in-Time: A Caregiver-Mediated Intervention for Toddlers With Autism

Abstract

Purpose: We investigated effects of an adaptive telehealth coaching model on caregiver implementation of enhanced milieu teaching (EMT) with newly diagnosed toddlers with autism. Method: Three caregiver–child dyads participated in a multiple-baseline-across-behaviors, single-case design. Caregivers were taught EMT via telehealth using the teach–model–coach–review approach. EMT strategies were taught sequentially in four components corresponding to design tiers. Caregivers reported their needs for support and adaptation via weekly surveys. Primary outcomes were measures of caregiver's implementation, including (a) a fidelity checklist for wholistic use of EMT and (b) a percentage of correct use of a subset of key EMT strategies (e.g., matched turns, target talk, expansions, play actions, milieu episodes). Generalization and maintenance of caregiver strategy use in uncoached home activities were measured. The number of different words used by children was measured as a secondary, descriptive outcome. Social validity data were collected through ratings and interviews at the end of the study. Results: There was a functional relation between the intervention and caregiver's implementation of EMT for all dyads. Caregiver's use of EMT strategies often generalized and maintained post-intervention. Child response to intervention was variable. Social validity data indicated that the model was beneficial to caregivers and children. Conclusions: An adaptive telehealth coaching model is effective for teaching caregivers of toddlers with autism to implement EMT and potentially helps to bridge the gap between diagnosis and comprehensive intervention. Further exploration of the relation between caregiver fidelity and dosage of active ingredients and child spoken language outcomes is needed.
