Examining the clinical correlates of autism spectrum disorder in youth by ascertainment source.
Autism looks messier when it enters through the general-psychiatry door, so expect more comorbidity and plan a wider assessment.
01Research in Context
What this study did
Joshi et al. (2014) compared two groups of kids with autism. One group came through general psychiatry clinics. The other group was sent straight to autism specialty clinics.
The team looked at how many extra mental-health diagnoses each child carried. They also noted how severe the autism traits were.
What they found
Kids who landed in general psychiatry had more comorbid disorders. They also had broader, less classic autism profiles.
Both groups were struggling, but the general-psychiatry kids were carrying a heavier load.
How this fits with other research
Root et al. (2017) saw the same pattern in preschoolers. Kids found through research had milder symptoms than kids who showed up in clinics. Together these studies warn: where you find the child shapes what the child looks like.
Joshi et al. (2010) counted an average of six extra diagnoses in referred youth with ASD. The 2014 paper adds the twist that most of that burden sits in general-psychiatry waiting rooms, not autism clinics.
Ghumman et al. (2026) later showed that when major depression is one of those extras, it looks typical—no special autism version. So screen with standard tools and treat what you see.
Why it matters
If a child reaches you through a general mental-health door, plan for more than autism. Run full psychiatric screens, loop in medication partners, and budget extra time for case coordination. Kids who come straight to autism clinics still need checks, but the load is lighter. Match your assessment depth to the door they walked through.

03Original abstract
To examine whether presentation of autism spectrum disorder (ASD) and associated patterns of psychiatric comorbidity and dysfunction vary by referral source. ASD youth referred to a specialized ambulatory program for ASD (N = 143) were compared to ASD youth referred to a general child psychiatry clinic (N = 217). More ASD clinic youth met criteria for a more robust form of ASD (autistic disorder); more youth referred to the psychiatry clinic met criteria for broader spectrum ASD (pervasive developmental disorder not otherwise specified). General psychiatry clinic youth with ASD suffered from a greater burden of psychopathologies and higher levels of dysfunction. The presentation of ASD in psychiatrically referred youth differs between general and ASD-specialized clinics, though both referral populations have high levels of comorbidity and dysfunction.
