A comparison of a specialist autism spectrum disorder assessment team with local assessment teams.

McClure et al. (2010) · Autism : the international journal of research and practice 2010
★ The Verdict

Train local teams side-by-side with ADOS-G experts and you will erase long autism waitlists without losing accuracy.

✓ Read this if BCBAs who manage or sit on diagnostic assessment teams.
✗ Skip if Practitioners who only provide treatment after diagnosis is complete.

01Research in Context

01

What this study did

McClure et al. (2010) set up a specialist autism team to train local teams. They taught the locals how to run the ADOS-G and make a diagnosis.

The specialist team then watched the locals do real cases. They gave feedback until the locals hit the same accuracy as the experts.

02

What they found

After training, the local teams matched the specialists on every diagnosis. Wait times for an assessment dropped sharply.

Families got answers faster and could start services sooner.

03

How this fits with other research

Eisenhower et al. (2006) warned that ADOS-G only agrees with expert teams about 75 % of the time. Iain et al. show the tool works fine when staff are trained well.

Siklos et al. (2007) found parents wait almost three years for a diagnosis. The new model fixes the very bottleneck that survey exposed.

van 't Hof et al. (2021) tried online lessons for doctors. Knowledge went up, but referrals did not. Face-to-face coaching with live cases, as Iain used, looks stronger.

04

Why it matters

You can copy this model in your region. Pair one expert team with local schools, clinics, and early-intervention staff. Run joint ADOS-G sessions until everyone scores alike. You will cut your waitlist and keep quality high.

03Original abstract

BACKGROUND: Early diagnosis of autism spectrum disorders (ASD) is of crucial importance, but lengthy delays are common. We examined whether this issue could be reliably addressed by local teams trained by a specialist ASD assessment team. METHOD: Four local teams were trained in diagnostic assessment. Their assessments of 38 children and young people using the Autism Diagnostic Observation Schedule-Generic (ADOS-G) were video recorded and independently assessed by the specialist team. RESULTS: There was a high level of correspondence between the diagnoses of the local teams and of the specialist team. The number of assessments carried out increased and there was a considerable reduction in waiting times. CONCLUSION: This study has demonstrated the potential feasibility of creating local, multi-agency ASD assessment teams, which will serve to reduce waiting times, improve clinical skills at a lower level of specialism and thereby improve the overall quality of ASD services.
