Peer Interventions for Preschoolers With Autism
(PIPA)
What this study is about
This proposal will evaluate a series of peer-mediated interventions (PMIs) for preschool children (3 to 6 years) with ASD and limited or no spoken language, using an innovative Sequential Multiple Assignment randomly assigned Trial (SMART) design. Available evidence supports the beneficial effects of PMIs for improving social communication in children with ASD.
View original scientific description
This proposal will evaluate a series of peer-mediated interventions (PMIs) for preschool children (3 to 6 years) with ASD and limited or no spoken language, using an innovative Sequential Multiple Assignment Randomized Trial (SMART) design. Available evidence supports the beneficial effects of PMIs for improving social communication in children with ASD. Peer-related social competence is vital to a wide range of child outcomes, such as improved communication and fewer behavioral problems. Unfortunately, approximately 30% of children with ASD remain minimally-verbal in kindergarten, restricting participation in inclusive activities. Recent studies report improved communication after a speech-generating device (SGD) is included in treatment. Effective interventions that can be modified is necessary to ensure optimal communication outcomes when children do not make anticipated progress. A strength of the study is that these interventions can be adopted by community-based, early service providers. All participants will receive an adapted Stay-Play-Talk (SPT) peer-mediated intervention that varies in active ingredients. With SMART designs, it is possible to test and identify alternative combinations of PMI approaches, such as the addition of a SGD. In this study, 132 preschoolers with ASD (and N=264 peers without disabilities) will be initially randomized to SPT and SGD with spoken peer input only (SPT Basic; peers taught to model language) or SPT and SGD with augmented peer input (SPT Plus; peers taught to use verbal language models concurrently with the SGD). Each child's response to treatment after 5 weeks will determine that child's next phase in the SMART design. Children showing a positive response will continue in their originally assigned group; slow responders will be randomly assigned to receive added treatment components to improve communication (either SPT Plus or SPT Advanced). SPT Advanced adds direct instruction strategies (i.e., adult prompts, reinforcers, and teaching trials) to increase child vocalizations in SGD interventions. The use of a SMART design extends our prior work by testing the systematic addition of selected peer-mediated strategies in combination with an SGD that allows for flexible application of interventions based on child response. The investigators have assembled an outstanding team of highly qualified investigators with complementary skills in preschool assessment, language intervention, clinical trials, and statistics.

Exclusion criteria
- co-morbid or major medical conditions other than ASD, based on caregiver and teacher report
- significant physical, sensory, or motor impairments that would prevent playing with another child

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
