Tailoring Treatment Targets for Early Autism Intervention in Africa

Tailoring Treatment Targets for Early Autism Intervention in Africa

Naturalistic Developmental Behavioral Interventions (NDBIs), an evidence-based early autism spectrum disorder (ASD) intervention approach, target key behaviors that help language development. While efforts to use NDBIs are increasing worldwide, important gaps in our knowledge remain on whether the behaviors targeted by NDBIs are cross-culturally valid. This study in South Africa, a multi-cultural setting, will provide critical information on NDBI treatment targets and a novel digital outcome measure of treatment response.

COVID-19 adaptations: We aim to develop and implement telehealth NDBI coaching and utilize a mixed methods approach to gather implementation and preliminary effectiveness data on the telehealth intervention.

COVID-19 has significantly impacted autism spectrum disorder (ASD) clinical research and disrupted access to intervention services for children and families globally. In this ongoing study in Cape Town South Africa, a caregiver coaching Naturalistic Developmental Behavioral Intervention (NDBI) for young children with ASD has been adapted for implementation by non-specialists and implementation and clinical outcomes are being evaluated. For ongoing clinical trials, the University of Cape Town Institutional Review Board (IRB) has encouraged researchers to switch to a virtual platform, where possible. Telehealth caregiver coaching is cost-effective, increases access to rural and underserved populations, and improves understanding of family home and caregiving routines. We aim to develop and implement telehealth NDBI coaching and utilize a mixed methods approach and a longitudinal pre-post design to gather implementation and preliminary effectiveness data on the telehealth intervention.
