Managing Anxiety in Autistic Children
Direct answer
About 4 in 10 autistic children and adolescents (39.6%) have at least one anxiety disorder, compared with an estimated 2.2-27% of typically developing children (van Steensel et al., 2011). Adapted Cognitive Behavioural Therapy (CBT) programs like Facing Your Fears (Reaven et al., 2012) show significant anxiety reduction when modified for autistic learners. Treatment options include adapted CBT, medication (SSRIs under physician supervision), and anxiety management strategies tailored to the individual's sensory and communication profile.

Why Timing Matters
The wait outlasts the window.
Clinical research (American Academy of Pediatrics; Hyman et al., Pediatrics 2020) identifies birth to age six as the peak neuroplasticity window for autism intervention. Ontario's reported minimum wait is 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026).
Example: an illustrative child's journey through the Ontario Autism Program
Registered at age 3. Services begin at age 8, after 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026), most of it inside the intervention window.
| Measure | Age range |
|---|---|
| Early-intervention window (AAP) | Birth to age 6 |
| Example wait using the OAC-reported minimum (registered age 3) | Age 3 to age 8 (5 years) |
| Age when services begin in this example | Past age 6 |
✓ Intervention before 6
Research shows 2× greater gains in cognitive and adaptive functioning. Some children lose their diagnosis entirely. The brain's plasticity makes early therapy dramatically more effective.
◌ Intervention after 6
Reduced neuroplasticity means slower progress, higher lifetime costs, and poorer outcomes. Every year of delay narrows the range of achievable milestones. Ontario's waitlist guarantees this for most families.
Of the 71,263 children on the unfunded backlog, the majority were registered between ages 2 and 4. At the current pace, most will age past 6 before receiving any core funding , missing the window that the American Academy of Pediatrics and every major autism research body identifies as critical.

Understanding Anxiety in Autism
- Anxiety in autistic children often presents differently than in neurotypical peers. It may manifest as increased repetitive behaviours, meltdowns, avoidance of specific settings or activities, insistence on sameness, and physical symptoms (stomach aches, headaches). Van Steensel et al. (2011) meta-analysis found that 39.6% of autistic youth meet criteria for at least one anxiety disorder, with specific phobia most common (29.8%), followed by OCD (17.4%) and social anxiety (16.6%).
- Anxiety can be driven by sensory overload, difficulty predicting social situations, intolerance of uncertainty, and challenges communicating distress. It is critical to distinguish anxiety-driven behaviours from core autism features, as the treatment approaches differ. A comprehensive assessment by a psychologist experienced with autism is recommended.
Treatment Options in Ontario
- Adapted CBT programs modify traditional CBT for autistic learners: using visual supports, incorporating special interests, reducing abstract language, and including parent components. Facing Your Fears (Reaven et al., 2012) is a manualized group program with trial evidence for autistic children.
- A physician may prescribe selective serotonin reuptake inhibitors (SSRIs) for moderate-to-severe anxiety that behavioural approaches have not helped enough. That decision rests with your clinician. Public waits for child psychiatry vary widely and can be long, so ask the referring clinic what to expect. Private psychologists offering adapted CBT commonly charge about two hundred eleven to two hundred seventy-five dollars an hour (Ontario Psychological Association 2024 fee survey), and rates differ by provider.
Frequently asked questions
Very common. Meta-analysis by van Steensel et al. (2011) found that about 40% (39.6%) of autistic children meet criteria for at least one anxiety disorder, compared with an estimated 2.2-27% of typically developing children. Specific phobia is the most common type, followed by OCD and social anxiety.
Yes, when adapted for autistic learners. Programs like Facing Your Fears use visual supports, concrete language, and special interest integration. In one trial, half the children in adapted group CBT improved in a clinically meaningful way, which the authors called generally consistent with other CBT studies (Reaven et al., 2012).
Yes. OAP core clinical services include mental health services, such as counselling and psychotherapy, which can help with anxiety. A regulated professional, such as a psychologist, psychotherapist, social worker, occupational therapist, nurse or physician, must deliver or supervise them. If your child is 24 or under and has no private drug plan, OHIP+ covers many prescribed medications, including antidepressants.
