What this trial studies

This randomized intervention offers an online, parent-mediated early behavioral intervention (OPT-In-Early) to families of children awaiting an autism diagnostic evaluation. Eligible children are 16–48 months old, identified as at-risk on the M-CHAT-R/F, and have not yet received a formal autism diagnosis or intensive autism-specific therapy. Participants are randomized to receive the online parent training promptly or to continue usual care/waitlist procedures, with outcomes measured in child social-communication and parent implementation of strategies. The approach aims to deliver evidence-based practices sooner by teaching caregivers skills they can use while diagnostic and service access delays are resolved.

Who should consider this trial

Good fit: Ideal candidates are English-speaking caregivers of children aged 16–48 months who are on a waitlist for a formal autism evaluation and screen positive on the M-CHAT-R/F but do not yet have a formal autism diagnosis.

Not a fit: Children who already have a formal autism diagnosis, are receiving more than 5 hours per week of evidence-based autism-specific intervention, or have major medical, motor, sensory, or genetic conditions listed in the exclusions may not benefit from this program.

Why it matters

Potential benefit: If successful, the program could give families practical tools to improve early social and communication skills before a formal diagnosis and reduce lost time waiting for services.

How similar studies have performed: Prior clinical trials of parent-mediated early interventions have demonstrated benefits, so this program builds on an evidence base that shows promise for early caregiver-delivered approaches.
