A Digital Health Parent-Training Intervention for Children With Social Communication Delays
What this study is about
Early intervention, during a time of optimal brain plasticity, is critical for autistic children to develop functional skills such as communication and daily living abilities.
View original scientific description
Early intervention, during a time of optimal brain plasticity, is critical for autistic children to develop functional skills such as communication and daily living abilities. However, many families face barriers to accessing timely autism-specific services due to delays in autism diagnosis (which is often a prerequisite to autism-specific intervention), long waitlists, high costs, and the necessity to travel far distances to service providers. Self-directed parent-mediated digital health interventions (i.e., programs that parents complete online without provider coaching or feedback) offer a scalable solution to reduce challenges accessing intervention by providing evidence-based strategies that parents can implement without relying on traditional service pathways. The proposed pilot randomized controlled trial (RCT) will test a revised self-directed parent-training program, that teaches parents naturalistic developmental behavioral intervention (NDBI) strategies, which have proven effective for young children with autism. The study will include young children who have already been diagnosed with autism and those who screen positive on an autism screener but have not yet been evaluated, enabling earlier intervention before a formal diagnosis. The study will also explore parents' willingness to engage in the intervention. The specific research aims are: (1) test the preliminary efficacy of the parent-training program vs. treatment as usual (TAU) for 50 children with autism traits and their parents; (2) examine parent engagement in the intervention; and (3) explore predictors of engagement.
Interventions
BEHAVIORAL
Online Parent Training in Early Behavioral Intervention (OPT-In-Early)
OPT-In-Early is an online 14-module self-directed naturalistic developmental behavioral intervention (NDBI) that uses simple text, narration, and interspersed videos to teach parents how to increase their children's social engagement, communication, adaptive behaviors, and reduce challenging behaviors.
Primary outcome measures
Motor Imitation Scale
Time frame: Baseline and 4 months
We will administer a revised Motor Imitation Scale (MIS), a standardized, structured observational measure that assesses a child's ability to imitate familiar and novel motor actions. Children will see 5 actions modeled and then will be prompted to imitate the action using a matching toy. Children are given up to three opportunities to imitate each action. MIS scores range from 0 to 10, with higher scores indicating greater imitation.
Vineland Scales of Adaptive Behavior-3
Time frame: Baseline and 4 months
The Vineland Scales of Adaptive Behavior-3 (Vineland-3) is a standardized parent interview measuring adaptive functioning. It will be administered to all participants at pre- and post-treatment to evaluate change occurring in adaptive behavior across groups. Previous research has documented that this measure has robust psychometric properties, is sensitive to change in response to early intervention, and captures dimensions that are highly valued by stakeholders. Higher scores in the Vineland indicate more advanced adaptive skills.
MacArthur-Bates Communicative Development Inventories (MCDI)
Time frame: Baseline and 4 months
The MacArthur Bates Communication Development Inventory (MCDI) is a parent-report measure that assesses nonverbal communication (gestures) and verbal communication (words). The Words and Gestures form will be used. The MCDI is widely used, standardized, and validated. It is particularly well-suited for large-scale research due to ease of administration, strong psychometric properties, and sensitivity to individual differences in early language development. Higher scores indicate greater communication.

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.
