Online Spanish PRT Training for Parents of Young Children with ASD

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study tests a 12-week online course in Spanish for mothers and other Spanish-speaking caregivers to learn PRT techniques. Participants complete online lessons and have regular check-ins via phone or video, submitting practice videos to show how they apply PRT with their child. The goal is to see if caregiver training in Spanish can improve the child’s communication and social interactions, with outcomes assessed through parent reports, video submissions, and follow-up contact. The trial focuses on young children with ASD who have significant language delays and limited access to services due to language and cost barriers. Conducted at Stanford with collaboration from UC Santa Barbara, the study emphasizes accessibility and practical use of PRT in the home setting.
