Study looks at which parts of clinician training help deliver an autism parent-coaching programme in US community services

A new study in the Journal of Autism and Developmental Disorders, published on 4 November 2026, looks at how clinicians are supported to deliver a parent-coaching programme for autistic children. It asks which parts of their training make a difference.

The programme is called Project ImPACT. The researchers describe it as a caregiver coaching intervention for autism, meaning clinicians coach parents and carers rather than working only with the child. This study took place in a community mental health system in the United States. It involved families whose autistic children were enrolled in Medicaid, a US public health insurance programme.

What the researchers studied

The team followed 20 clinicians across six agencies. They scored video recordings of 154 telehealth (video call) sessions with 21 families.

The clinicians took part in group ‘consultation’ training activities, which came in three parts:

• case support, talking through their own cases
• practising skills through role play
• getting feedback on video recordings of their sessions

The researchers looked at two kinds of result. The first was ‘fidelity’, meaning how closely clinicians stuck to the manual and how competent their coaching was across five coaching areas. The second was ‘case penetration’, meaning the share of eligible clients who actually received the programme.

What they found

None of the three parts of consultation was linked to changes in how closely clinicians followed the manual.

One coaching skill did change. In the video-feedback phase, competency scores for ‘reflective coaching’ skills were 0.32 points higher than in the baseline phase. No other part of consultation was linked to changes in coaching competency.

The share of eligible clients receiving the programme did not change significantly during the baseline phase. It then rose significantly in the consultation phase.

The authors conclude that, to improve clinician fidelity in under-resourced settings, consultation should put more weight on performance feedback.

Limitations

This is a small study: 20 clinicians and 21 families, in one US system, with sessions delivered by video call. The results may not apply to other countries, services or face-to-face work.

The abstract describes the training in phases. It does not describe random allocation. That means changes could reflect time, growing experience or other factors rather than the training itself. The findings are associations, not proof of cause.

Importantly, the study measured what clinicians did. The abstract does not report whether autistic children or their families benefited, how they experienced the programme, or whether they wanted it. ‘Fidelity’ means following a manual well. It does not tell us whether the approach suits a given child or family.

The abstract does not say whether autistic people or families helped design or carry out the research. Research on how to roll out interventions more widely is more useful to autistic readers when it also asks whether those interventions respect autistic children’s wellbeing and ways of communicating.

The study was registered as a clinical trial (ClinicalTrials.gov ID NCT04654117). The paper is open access on SpringerLink.
