What this trial studies

Parents complete an online Pivotal Response Treatment (PRT-O) course designed to teach PRT strategies for improving young children's communication. Children must be aged 2:0–5:11 with a confirmed or suspected autism diagnosis and measurable adaptive communication deficits. Outcomes focus on whether parents learn to deliver PRT correctly and on related child communication measures, using standardized tools such as the Vineland and diagnostic review (e.g., ADI-R). The program is run through Stanford University with English-language participation required and some coordination for assessments.

Who should consider this trial

Good fit: Ideal candidates are children aged 2:0–5:11 with a confirmed or suspected ASD diagnosis, significant adaptive communication deficits, and an English-speaking parent who can consistently participate and deliver treatment, with any psychotropic or biomedical interventions stable for at least one month.

Not a fit: Children outside the 2–5 age range, families without an English-speaking parent who can participate consistently, or cases with severe co-occurring medical issues may not benefit from this online parent-training approach.

Why it matters

Potential benefit: If successful, this online training could let more parents learn PRT skills at home, increasing access to evidence-based coaching and potentially improving children's communication.

How similar studies have performed: Parent-mediated PRT and other parent-training approaches have shown benefits in prior research, but fully online PRT courses are less well-studied though early digital parent-coaching studies show promise.
