What this trial studies

This trial aims to evaluate the effectiveness of a virtual early intervention platform called Early Social Interaction Mobile Coaching (ESI-MC) for toddlers diagnosed with autism spectrum disorder (ASD). The study will recruit 360 children showing early signs of autism and will assess the impact of starting intervention at different ages (18, 24, or 30 months) using a modified stepped wedge design. Families will participate in individual telehealth sessions that provide coaching and feedback to integrate intervention strategies into daily activities. The trial will be conducted entirely online, from recruitment to intervention, to reach a diverse national sample.

Who should consider this trial

Good fit: Ideal candidates are toddlers aged 18 months with early signs of autism and a clinical diagnosis of ASD.

Not a fit: Patients who do not show early signs of autism or do not meet the diagnostic criteria for ASD may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could lead to improved developmental outcomes for toddlers with autism by starting evidence-based treatment earlier.

How similar studies have performed: Previous studies have shown promise in using telehealth for early intervention in autism, but this specific approach is relatively novel.

* Parent(s) agree to be in the intervention study by the time the child is 18 months (+/- 2 months) of age
