Supporting African communities to increase resilience and mental health of kids with developmental disabilities and their caregivers using the World Health Organization's Caregiver Skills Training Programme (SPARK trial): study protocol for a cluster randomised clinical controlled trial.

Background: Most children with developmental disabilities (DD) live in low- and middle-income countries, but access to services is limited, impacting their ability to thrive. Pilot study findings of the World Health Organization's Caregiver Skills Training (WHO CST) intervention, which equips caregivers with strategies to facilitate learning and adaptive behaviours in children with DD, are promising but evidence from an appropriately powered trial delivered by non-specialist facilitators is lacking. This study will investigate the effectiveness and the resource impacts and costs and consequences of the WHO CST intervention in four sites in rural and urban Kenya and Ethiopia.
