Brief Summary:
Purpose of the Research:
The goal of this clinical study is to investigate if a parent training program called "Project IMPACT" (Improving Parents as Communication Teachers) can help improve the core challenges in social interaction and communication for children with Autism Spectrum Disorder (ASD). And to explore whether and how this intervention affects children's brain activity.
Key Questions This Study Aims to Answer:
Does participation in the IMPACT parent training program significantly improve ASD symptoms, social communication abilities, and adaptive functioning in daily life for children with ASD compared to general intervention?
Study Design:
This is a assessor blinding randomized controlled trial. Participating children will be randomly assigned to one of two groups: IMPACT Intervention Group with primary caregiver conducting intervention and Control Group with current routine interventions provided by behavioral trainers.
The research team will evaluate all children at three time points: before the intervention starts, immediately after the 10 - week intervention period, and 6 months after the intervention ends. The measurements include social - related questionnaires, ADOS - 2, Griffiths Scales, eye - tracking, task - based fNIRS, and fMRI without sedation.

And to explore whether and how this intervention affects children's brain activity. We will use safe brain imaging techniques (such as MRI and functional Near-Infrared Spectroscopy, fNIRS) to compare changes in the brain before and after the intervention, aiming to understand the potential brain mechanisms behind behavioral progress. Ultimately, we hope to identify which types of children might benefit most from this intervention, providing insights for more personalized treatment recommendations in the future.
Key Questions This Study Aims to Answer:
Does participation in the IMPACT parent training program significantly improve ASD symptoms, social communication abilities, and adaptive functioning in daily life for children with ASD compared to general intervention?
Study Design:
This is a assessor blinding randomized controlled trial. Participating children will be randomly assigned to one of two groups:
IMPACT Intervention Group (approximately 40 children): The primary caregivers of these children will receive a systematic IMPACT training course over about 10 weeks (including group sessions and individual coaching), learning how to apply these techniques during interactions at home. All caregiver will be encouraged to conduct intervention at least 10 hours per week.
Control Group (approximately 40 children): The caregivers of these children will not receive IMPACT training during the initial 10-week period. They are encouraged to continue any current routine interventions their child is receiving. After 10 weeks, they will be offered the opportunity to receive the IMPACT training online for free as compensation.
Intervention Component (Exclusively for families randomly assigned to the ImPACT group):
Primary caregivers of participants will partake in the approximately 10 - week IMPACT parent training program. In weeks with odd numbers, caregivers will attend a group theory session lasting 3 - 4 hours. In weeks with even numbers, caregivers will receive a one - on - one coaching session (1 - 1.5 hours) with a trainer to enhance their intervention skills based on ImPACT. Caregivers are obligated to implement the learned strategies during daily home interactions with participants for a minimum of 10 hours per week and maintain a simple record of these activities. Trainers will monitor adherence via weekly reviews of activity logs and coaching sessions. Adherence will be further bolstered by real - time feedback during coaching sessions, where trainers prompt caregivers to engage their child in task - oriented activities while demonstrating and suggesting effective strategies, ensuring skill generalization in naturalistic settings.
The research team will evaluate all children at three time points: before the intervention starts, immediately after the 10-week intervention period, and 6 months after the intervention ends. The assessors will not know which group each child belongs to (they will be "blinded") to ensure objective results.
What the Involvement of Participation Entails:
If your child (aged 1.5 to 6.5 years) has a diagnosis of ASD and you agree to participate, the following may be involved:
Assessment Sessions (Three times: Pre-intervention, Post-intervention at 10 weeks, only SRS-2 measured after 6 months):
Questionnaires: You will be asked to fill out questionnaires about your child's behavior, social skills, and your own experiences and stress levels.
Child Assessments: A trained clinician, independent of the research team, will conduct standardized assessments of your child's development and social communication skills (e.g., ADOS-2, Griffiths Scales).
Eye-Tracking Test: Your child will watch short videos while a specialized, non-invasive device records where and for how long your child looks. This helps us understand their visual attention preferences towards social information.
Functional Near-Infrared Spectroscopy (fNIRS): During a play session, your child will wear a soft cap with sensors. It uses harmless near-infrared light to measure changes in brain activity in the outer layer of the brain. This procedure is safe, non-invasive, and radiation-free.
Magnetic Resonance Imaging (MRI) Scan (voluntary): We plan to conduct one brain MRI scan before and after the intervention for all willing participants to study brain structure and function. To ensure the child remains still during the scan, we plan to perform it during natural, deep sleep.
Voluntary Participation:
Participation in this study is completely voluntary. You may decide to withdraw yourself and your child from the study at any time, for any reason, without any penalty or effect on the future medical care you receive at this hospital or elsewhere.This study will be submitted for ethical review to ensure it meets scientific and ethical standards, protecting the rights, safety, and well-being of every participant.
