Many parents are unsure of where to turn or what steps to follow to have their child assessed for autism. They simply don’t know where to start to get an autism diagnosis.
- Do you have concerns about your child’s development?
- Have you brought them up to your child’s physician?
- Are you wondering what the process is to get an autism diagnosis in Ontario?
At your child’s 18 and 24 month check-ups the doctor should be screening your child for autism. They’re likely using a tool called the M-CHAT-R (Modified Checklist for Autism in Toddlers – Revised). The M-CHAT-R is 20 questions about your child’s behaviour. No screening tools catch EVERY child so even if your child passes the M-CHAT-R, you can still request the doctor make a referral to a specialist for further testing.
To diagnose autism, the person will use formal assessment tools and their clinical judgement. There isn’t a blood test or a scan that you can do that will show autism. Diagnosticians need to have a lot of training and experience identifying autism.
Paths to an autism diagnosis
There are three ways to get an autism diagnosis in Ontario.
Medical:
A family physician, a child’s paediatrician, a developmental paediatrician, a neurologist or a psychiatrist can all diagnose autism. OHIP pays for this assessment and it will not cost you anything. If your doctor is not able to reliably make the diagnosis, they would refer you to someone with more experience and training. Many physicians do not give a detailed report of the child’s level of functioning but will simply write a diagnosis letter. However, as with all OHIP services, there could be a wait to be assessed, especially if you need a referral.
A diagnostic hub:
There are 5 diagnostic hubs in the province. The hubs use a multi-disciplinary approach and perform standardized test. Specifically, there is usually a psychologist, an occupational therapist, a speech-language pathologist and a behaviour analyst on the diagnostic team. They will interview you and interact with your child for a few hours, usually over a few appointments. The provincial government pays for the assessment if it’s done at a hub. Nonetheless, the wait for an appointment can be OVER A YEAR. After the assessment you will receive a written report, describing your child’s behaviour and current level of functioning. Usually, the hub will have you come in for a summary meeting to discuss the findings and talk about next steps and referrals. The hub will give you a list of many resources in your community where you can turn for help.
A private assessment:
Some families choose to use a psychologist to provide the assessment and diagnosis. In fact, Autism testing can cost between $3000 and $5000. The psychologist will interview you and will do standardized tests with your child. Many psychologists use a test called the ADOS (Autism Diagnostic Observation Schedule). Often, psychologists recommend that parents not be in the room during testing. It can be very difficult for parents to watch. This is because your natural instinct is to help your child, but the point of the testing is to determine how your child behaves without assistance. Generally, the full assessment takes place over 3 or 4 visits. The first visit is a parent interview. The second and third are the testing with the child. The last appointment is usually the review of the findings and referrals.
Do you need an autism diagnosis to start treatment?
No! Every child who is not meeting their milestones would benefit from early intervention. Accessing Focused ABA , S-LP or OT services would benefit your child, especially while you’re waiting for a diagnostic assessment.
