Autism Spectrum Disorder Interventions in Resource-Limited Settings

Autism Spectrum Disorder (ASD) affects individuals globally, with a disproportionate challenge in low- and middle-income countries where specialised services are scarce. In resource-limited settings, interventions have evolved from highly professionalised models towards approaches that harness existing community structures. Early detection is increasingly achieved through simplified screening tools administered by trained non-specialists. Naturalistic, play-based therapies and parent-mediated programmes are adapted to local cultures and languages, emphasising everyday routines and caregiver competence. Task-sharing strategies delegate elements of assessment and intervention to community health workers or educators, with remote supervision from specialists via telehealth platforms where feasible. Capacity-building efforts include modular training materials, outreach campaigns to reduce stigma and scalable supervision frameworks. Stepped-care architectures allow for progressive intensification of support—from basic awareness sessions through structured group workshops to individualised interventions—optimising scarce professional resources. Successful models demonstrate gains in communication, adaptive behaviour and caregiver well-being. Continued innovation in open-access materials, community engagement and policy integration is vital to bridge the gap in ASD care and ensure equitable outcomes for children and families in under-resourced contexts.
