This Issue’s Focus: Increasing Access through Telehealth Coaching in Project ImPACT

Hero Graphic for Telehealth Coaching

With growing demand for accessible and personalized care, telehealth has emerged as a powerful platform for delivering parent-mediated interventions like Project ImPACT. This approach extends the reach of evidence-based practices to families in underserved areas and helps support families as they learn in their home. New research and clinical experience suggest that Project ImPACT and other parent-mediated NDBIs can be delivered effectively over telehealth and improve children’s social communication.

Research Spotlight


Telehealth coaching in Project ImPACT indirectly affects children’s expressive language ability through parent intervention strategy use and child intentional communication: An RCT

Authors: Brooke Ingersoll, Kyle M. Frost, Diondra Straiton, Anamiguel Pomales Ramos, and Karis Casagrande.
Journal: Autism Research, 17(10), 2177-2187. (2024)

This study examined the effect of telehealth delivery of Project ImPACT, a parent-mediated Naturalistic Developmental Behavioral Intervention (NDBI), on children’s expressive language ability. It used a randomized controlled trial to investigate if therapist-assisted coaching indirectly impacts child outcomes through changes in parent strategy use and child intentional communication.


What was done?

This was a randomized controlled trial (RCT) with intent-to-treat analysis. Participants were randomly assigned to one of three groups to receive 6 months of intervention. Assessments were conducted at intake, post-treatment, and 9-month follow-up.


Who was involved?

64 young autistic children (18-96 months at intake) and their primary caregivers participated. Children had a community diagnosis of ASD, met ADOS-2 criteria, and did not yet exhibit conversational speech. Families were recruited with a focus on underserved communities.


The intervention:

Project ImPACT: A parent-mediated NDBI. Participants were assigned to one of three groups for 6 months:

  • Therapist-Assisted (TA) ImPACT Online (n=22): 6 months of web program access + two 30-min telehealth coaching sessions/week.
  • Self-Directed (SD) ImPACT Online (n=24): 6 months of web program access + monthly support calls (no therapist coaching).
  • Informational Resources and Support (IRS) Control (n=18): Access to resources page + monthly phone calls for questions/resources.


When were measurements taken?


Intake


Post-Treatment


Follow-up


What was measured?

  • Parent Fidelity: Parents’ use of intervention strategies (rated 1-5) during parent-child interaction using Project ImPACT intervention fidelity checklist.
  • Child Intentional Communication: Weighted frequency of intentional communication (WFIC) coding scheme during parent-child interaction.
  • Child Expressive Language Ability: Composite score from multiple standardized assessments (Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, MacArthur-Bates Communicative Development Inventory).


Telehealth coaching works:

Parents who received telehealth coaching showed greater improvement in consistently using the intervention strategies.


A transactional cascade for language:

The study confirmed that telehealth coaching leads to parents using strategies more effectively, which then increases children’s intentional communication, and ultimately supports greater expressive language growth.


Self-directed programs need support:

While the self-directed group also saw some gains in parent intervention use, a high number of parents did not fully engage without therapist assistance, suggesting additional support is often needed.


Indirect impact:

Group assignment did not directly affect children’s expressive language outcomes. Rather, telehealth coaching in Project ImPACT indirectly improved expressive language by first influencing parent behavior and child intentional communication.


Wider access to care:

This research provides strong evidence that telehealth is an effective way to deliver parent-mediated interventions for autism, making these services more accessible, especially for families in underserved areas.


Understanding the pathway:

It clarifies the vital steps in how these interventions support children’s development: effective parent strategy use is a key mediator for improved child communication and language skills.


Tailored support is key:

It highlights that while online resources are valuable, many families benefit significantly from the personalized guidance of a therapist to fully implement the strategies.

Practice Notes

Enhancing Parent Engagement in Telehealth Coaching

This study highlights the critical role of therapist coaching in parent-mediated interventions delivered via telehealth. To maximize outcomes, clinicians should focus on strategies that promote consistent parent engagement and high fidelity to intervention techniques.

Strategies for Effective Telehealth Coaching:

  • 🔑 Coaching Is Key to Parent Learning: Parents learn most effectively when guided by a coach who tailors support to their needs. Whether in individual or group formats, coaching should be central to every intervention. Prioritize individualized sessions to reinforce strategies, build confidence, and promote fidelity—especially as techniques grow more complex.
  • 📱 Address Practical and Technological Barriers: Support families by offering flexible scheduling, mobile-friendly formats, and integration into daily routines. Ensure access by providing initial help with tech and home setup.
  • 🎥 Encourage Parent Video Reflection: Ask parents to share videos of their practice between sessions to enable targeted coaching and support continuous learning.
  • 🎓 Use Alternative Modeling Strategies to Support Instruction: In virtual formats where live modeling with the child may not be possible, compensate with detailed verbal explanations, role play with the parent, and frequent invitations for questions. Enhance learning by screensharing instructional materials such as the parent manual, annotated slides, and video examples.
  • 💻 Use Technology to Reinforce Learning Between Sessions: Leverage asynchronous tools—such as video sharing, chat threads, and feedback forms—to sustain progress outside live coaching. These platforms can support booster training, allow parents to reflect on and review strategies, and receive individualized feedback on their practice videos.
  • 🧑‍🤝‍🧑 Use Video Conferencing Features to Facilitate Group Interactions During Sessions: When interventions are delivered in a group format, use built-in platform tools like breakout rooms for small group coaching, whiteboards for collaborative exercises, and chat functions to encourage questions and peer engagement in real time. These interactive features help replicate group dynamics that foster shared learning and peer support.
  • 🔀 Offer Flexible Formats to Meet Family Needs: Support diverse preferences by offering telehealth-only or hybrid models that blend in-person instruction with remote coaching.

Clinician FAQ: “How do I ensure parents apply strategies consistently outside of sessions?”

Answer: Focus on helping parents identify natural opportunities within their daily routines. Encourage small, manageable practice goals. Use a collaborative problem-solving approach to address challenges, and celebrate even small successes to build parent confidence and reinforce continued effort. Consider providing visual aids or checklists for home practice.

Fidelity Reminder: Continuous Support for Self-Directed Learning

While therapist-assisted coaching is highly effective, self-directed programs can increase access. For self-directed models, consider incorporating additional supports like more frequent check-ins, automated reminders, or peer support groups to improve completion rates and sustained engagement.
