What is the purpose of this trial?

This trial focuses on finding the best way to improve language skills in preschoolers with autism who have limited verbal abilities. It aims to determine how different intervention methods, such as DTT (Discrete Trial Training, a form of Applied Behavior Analysis) and JASPER (Joint Attention, Symbolic Play, Engagement, and Regulation), can enhance communication by age six. The study tests various combinations and intensities of these treatments to tailor the approach to each child's needs. Eligible children have been diagnosed with autism, have fewer than 20 functional words in their vocabulary, and have participated in early intervention or preschool for at least three months. As an unphased trial, this study offers a unique opportunity to contribute to pioneering research that could significantly enhance communication strategies for children with autism.

Do I need to stop my current medications for the trial?

The trial requires that participants have stable medication for the past 6 months, so you should not change your current medications if you want to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that both JASPER and DTT are safe and well-tolerated treatments for children with autism. JASPER, a play-based therapy, helps children improve social skills and communication without major side effects. Studies have found that children in these programs demonstrate significant improvements in joint attention and play skills, which are crucial for development.

DTT, or Discrete Trial Training, is a teaching method that breaks down skills into small, easy-to-learn steps. Research supports its effectiveness for children with autism, ages 3 to 11. This method teaches new skills through repetition and positive feedback.

Both treatments aim to enhance developmental skills in children with autism, and studies report no significant adverse effects, suggesting they are safe and well-tolerated options for young children. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the DTT (Discrete Trial Training) and JASPER (Joint Attention, Symbolic Play, Engagement, and Regulation) techniques for autism because they offer tailored, responsive approaches to therapy. Unlike current standard treatments like Applied Behavior Analysis (ABA), these methods can adapt to a child's individual response rate. If a child responds quickly to either DTT or JASPER, they continue with the same treatment, but slower responders receive either an enhanced or intensified version of their therapy. This flexibility allows for more personalized and potentially more effective interactions, aiming to improve developmental outcomes in children with autism.

What evidence suggests that this trial's treatments could be effective for autism?

Research has shown that JASPER (Joint Attention, Symbolic Play, Engagement, and Regulation), one of the treatments in this trial, can greatly enhance social communication skills in children with autism. Studies indicate that children participating in JASPER often experience improved joint engagement and play skills. Joint engagement is crucial, accounting for 69% of the improvement in children's social communication abilities.

Similarly, Discrete Trial Training (DTT), another treatment option in this trial, is a proven method for assisting children with autism. DTT breaks skills into smaller, manageable steps and has improved social skills through structured teaching. Research has found that children with autism who participate in DTT show significant improvements in specific behaviors and learning outcomes. Both JASPER and DTT effectively help children with autism develop essential communication and social skills. ^{1 2 6 7 8}

Trial Overview

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.

How Is the Trial Designed?

Group I: JASPER Active Control 1 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: DTT Active Control 1 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).
