Service Delivery

Mental health services and young people with intellectual disability: is it time to do better?

McCarthy et al. (2002) · Journal of intellectual disability research : JIDR 2002
★ The Verdict

Most teens with ID and clear mental health problems still get no specialist care, so BCBAs must screen loud and refer early.

✓ Read this if BCBAs working with adolescents who have intellectual disability in school or clinic settings.
✗ Skip if Practitioners who serve only typically developing clients or adults with ID.

01Research in Context

01

What this study did

The authors looked at teens who had both intellectual disability and ongoing mental health problems. They asked a simple question: how many of these kids actually see a mental health specialist?

Using clinic records, they counted who got services and who did not. The study was small, but the pattern was stark.

02

What they found

Two-thirds of the teens received zero specialist mental health care. The kids were already known to have ID and clear mental health needs, yet services never arrived.

The gap was not a mystery of hidden needs. The needs were on paper. The services were simply missing.

03

How this fits with other research

Chiviacowsky et al. (2013) helps explain the gap. In their survey, most psychiatrists admitted they felt under-trained to treat people with ID. If the doctors themselves lack confidence, referrals dry up.

Dion et al. (2018) looks at the same population from another angle. They show that kids with ID do enter services—through child protection doors—after abuse is proven. The contrast is sharp: services appear after crisis, not before.

Lunsky et al. (2024) pick up the baton. They argue the fix is partnership: include people with ID and families at every planning table. The 2002 cry of "time to do better" becomes a 2024 roadmap for co-design.

Why it matters

If you work with youth who have ID, screen for mental health issues at every visit. Do not wait for a referral that may never come. Use simple checklists, talk with parents, and push the referral yourself. The system still acts only when needs are loud, so make the need visible early.

03Original abstract

BACKGROUND: There is evidence that the mental health needs of children with disabilities are inadequate. The aim of the present study was to determine the extent of specialist health service use during adolescence by a group of individuals with intellectual disability (ID) and mental health problems. METHOD: The study population consisted of 80 young people with ID, who were examined in childhood and adolescence for psychiatric and behaviour disorder. These young people were interviewed again in early adult life for the presence of psychiatric and behaviour disorder. Evaluation questionnaires were used during the follow-up study to assess service use from adolescence. RESULTS: The key finding was that the great majority (64%) of subjects with persistent challenging behaviour from childhood into adult life and those with an established childhood psychiatric disorder received no specialist mental health care. CONCLUSIONS: The development of mental health services for this vulnerable group with complex psychiatric and behaviour disorders has been poor for a number of reasons, including lack of recognition at the primary care level and insufficient numbers of trained professionals within specialist services.
