Summary

This trial aims to improve language skills in preschool children with autism using a structured teaching and social interaction-based learning program. The program is adjusted based on each child's progress. The goal is to help these children develop better communication skills and avoid being minimally verbal by age 6.

Who is the study for?
The PRISM study is for preschoolers aged 36-59 months with Autism Spectrum Disorder who speak less than 20 functional words. They must have had over 3 months of early intervention, stable medication for the past half year, and a nonverbal mental age above one year. Children with sensory/motor impairments or genetic syndromes like Down Syndrome are not eligible.
What is being tested?
This trial tests an adaptive two-stage language development approach over 20 weeks for minimally verbal children with ASD in community settings. It aims to personalize treatment by choosing between DTT (Discrete Trial Training), JASPER, and CET interventions based on each child's needs.
What are the potential side effects?
Since this trial involves behavioral interventions rather than medications, traditional side effects are not expected. However, there may be varying responses to therapy such as changes in behavior or emotional distress.

Trial Design

2Treatment groups
Active Control
Group I: JASPERActive Control1 Intervention
Child will spend 2 hours per week (2 days, 1 hour per day) for the first 10 weeks doing JASPER. If the child is an early responder, he/she will remain in the same course for the following 10 weeks. If child is a slow responder, he/she will be randomized for either combined \& enhanced treatment (CET) for 2 hours a week (2 days, 1 hour per day) or Intensified JASPER for 4 hours a week (4 days, 1 hour per day).
Group II: DTTActive Control1 Intervention
Child will spend 2 hours per week (2 days, 1 hour per day) for the first 10 weeks doing DTT. If the child is an early responder, he/she will remain in the same course for the following 10 weeks. If child is a slow responder, he/she will be randomized for either combined \& enhanced treatment (CET) for 2 hours a week (2 days, 1 hour per day) or Intensified DTT for 4 hours a week (4 days, 1 hour per day).

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Discrete Trial Training (DTT) is a structured behavioral intervention that breaks down skills into small, teachable components and uses reinforcement to encourage desired behaviors. JASPER focuses on improving joint attention and symbolic play skills, which are critical for social communication development. Enhanced Milieu Teaching (EMT) combines behavioral and developmental principles to promote spontaneous communication in naturalistic settings. These treatments are important for ASD patients because they target specific deficits in communication and social interaction, which are core challenges in ASD. By tailoring these interventions to individual needs, they can more effectively promote skill development and improve overall functioning.
