There is a high demand for quality early intervention services for autistic children and their families. A key part of effective early intervention is teaching caregivers how to support their child's development through caregiver-mediated interventions. However, in publicly funded programs, these strategies are often not followed correctly. Some studies suggest that family characteristics may influence how well clinicians apply these coaching methods. In this study, we explored the connection between family factors, like household income and language spoken at home, and the way clinicians coached families. We found that clinicians used coaching strategies less consistently with both lower- and higher-income families compared to middle-income ones. In addition, families that spoke only English at home received less consistent coaching than those who spoke other languages. These findings highlight the complex relationship between family background and how early intervention services are delivered, suggesting a need for further research.
