She's been in disability services her whole life. Group homes since childhood. Multiple workers. Constant turnover. Decisions made about her, rarely with her.
She's 28 now. Officially diagnosed with intellectual disability and autism. Also: anxiety, PTSD, attachment difficulties, trust issues.
The system calls these separate conditions requiring separate treatments.
But they're not separate.
The trauma is often because of the disability services. And the disability services aren't equipped to address the trauma they've caused.
This is the reality for many people with disability: disability and trauma so entwined they can't be separated. Trauma from ableism. Trauma from institutions. Trauma from loss of autonomy. Trauma from abuse that happened because they had disability and were vulnerable.
Understanding this intersection changes everything about how we support people.
Let me show you why trauma is so common in disability contexts, how it shows up, and what trauma-informed disability support actually looks like.
Why Trauma Is Common in Disability Contexts
1. Higher Rates of Abuse and Violence
People with disability experience violence at rates 1.5 to 10 times higher than people without disability.
Why:
Perceived as vulnerable targets
Communication barriers make reporting difficult
Dependence on carers creates power imbalance
Social isolation reduces protective factors
Perpetrators know they're less likely to be believed
Types:
Physical abuse
Sexual abuse
Financial abuse
Emotional abuse
Neglect
And often, the perpetrators are carers, support workers, or family members.
2. Institutional Trauma
Many people with disability have spent time in institutions:
Group homes
Residential facilities
Psychiatric hospitals
Special schools
Segregated settings
Institutional trauma includes:
Loss of autonomy (no choice, no control)
Depersonalisation (treated as case number, not person)
Rigid routines and rules
Restrictive practices (restraint, seclusion, forced medication)
Separation from family and community
Lack of privacy
Witnessing others being harmed
Even "good" institutions cause harm because institutionalisation itself is traumatic.
3. Medical Trauma
People with disability often have extensive medical histories:
Multiple surgeries
Painful procedures
Hospitalisations
Invasive assessments
Body viewed as problem to fix
Medical trauma includes:
Pain and discomfort
Loss of control over own body
Being touched/examined without full consent
Procedures that feel violating
Not being believed about pain
Being experimented on
Even necessary medical care can be traumatic.
4. Ableist Trauma
Living in an ableist world is traumatic.
Ableist trauma includes:
Constant microaggressions
Discrimination and rejection
Being told you're less valuable
Exclusion from spaces, activities, relationships
Having to constantly justify your existence
Being inspiration porn or pity object
Violence and hate crimes
Systemic barriers everywhere
Death by a thousand cuts.
5. Childhood Trauma
Children with disability experience trauma at higher rates:
Bullying (disability is major risk factor)
Social rejection
Family stress (some families struggle with disability)
Being "different" (internalised shame)
Therapy that feels like punishment
Medical procedures
Institutionalisation
Abuse and neglect
Developmental trauma shapes everything that follows.
6. Loss and Grief
Many people with disability experience significant losses:
Loss of function (acquired disability)
Loss of identity
Loss of future imagined
Loss of relationships
Loss of independence
Grief that's often disenfranchised (not recognised or supported)
Unprocessed grief becomes trauma.
7. Service-Caused Harm
As we discussed in a previous article (When Services Cause Harm: Rebuilding Trust), services themselves cause trauma:
Broken promises
Confidentiality breaches
Coercion
Discrimination
Inadequate support
System failures with serious consequences
The very systems meant to help often harm.
How Trauma Shows Up in Disability Contexts
Challenge: Overlapping Presentations
Trauma responses can look like:
Behaviour of concern
Mental health symptoms
Autism characteristics
Intellectual disability traits
"Non-compliance"
"Resistance to support"
Example: Hypervigilance
Could be:
Trauma response (learned from abuse)
Autism (sensory sensitivities, need for predictability)
Anxiety disorder
Intellectual disability (difficulty processing information)
Often, it's all of these. Trauma and disability aren't separate, they interact.
Common Presentations
1. Difficulty with Trust and Relationships
Learned from repeated betrayals
Makes support relationships difficult
Testing behaviour
Pushing people away
Avoiding closeness
2. Heightened Anxiety
Trauma combined with uncertainty of life as person with disability
Fear of future
Hypervigilance about safety
Panic in specific situations (medical, institutional)
3. Behaviours of Concern
Often trauma responses labelled as "behaviour"
Aggression equals fight response
Withdrawal equals freeze response
Running away equals flight response
Self-injury equals coping with overwhelm
4. Dissociation
Common trauma response
Can be mistaken for intellectual disability or autism
Spacing out, disconnection, memory gaps
Developed as survival strategy
5. Difficulty Regulating Emotions
Never learned regulation (developmental trauma)
Overwhelm from trauma triggers
Alexithymia (difficulty identifying emotions)
Limited support to develop regulation
6. Physical Health Issues
Trauma lives in body
Chronic pain
Gastrointestinal issues
Sleep difficulties
Immune system impacts
Why Standard Trauma Treatment Often Doesn't Work
1. Not Designed for People with Disability
Most trauma therapies assume:
Verbal communication capacity
Abstract thinking ability
Memory for processing past events
Ability to tolerate distress
No ongoing trauma
Many people with disability don't fit these assumptions.
2. Accessibility Barriers
Trauma therapy often not accessible:
Verbal therapy only (excludes non-verbal people)
No Easy Read materials
Not sensory-friendly
Requires independent attendance
Expensive
Wait lists
NDIS vs Medicare funding confusion
3. Ongoing Trauma
Standard trauma treatment assumes trauma is past.
For many people with disability, trauma is ongoing:
Still in institutional settings
Still experiencing ableism daily
Still dependent on potentially harmful systems
Still vulnerable to abuse
Can't process past trauma while current trauma continues.
4. Compounding Marginalisations
Trauma therapy often doesn't address:
Intersection of disability and other marginalisations
Ableism as source of trauma
Systemic and structural causes
Poverty, housing insecurity, isolation
Individual therapy can't fix systemic problems.
What Trauma-Informed Disability Support Looks Like
1. Assume Trauma Is Present
Don't wait for disclosure or diagnosis.
Assume:
Trauma history is likely
Current stressors exist
Behaviour makes sense in trauma context
Relationships are difficult for good reason
This assumption changes how you approach everything.
2. Safety as Foundation
Create safety in relationship:
Predictability (same worker, consistent routine)
Transparency (explain what you're doing and why)
Choice (offer options wherever possible)
Gentle pacing (no rush, no pressure)
Physical safety (respect personal space, no surprise touch)
Without safety, nothing else works.
3. Relationship-Based Healing
The relationship is the intervention.
For relational trauma (which most disability trauma is), healing happens through safe relationships.
This means:
Consistency matters more than interventions
You showing up reliably is treatment
Repair after rupture is essential
Building trust takes time (sometimes years)
4. Communication Accessibility
Trauma work must be accessible.
Adapt to communication needs:
Non-verbal communication (AAC, PECS, sign, visuals)
Concrete language (avoid abstract concepts)
Visual supports (pictures, symbols, written words)
Body-based approaches (movement, sensory)
Creative methods (art, music, play)
Meet people where they are, not where therapy manuals expect them to be.
5. Choice and Control
Trauma removes control. Healing restores it.
Offer choices constantly:
Where to meet
What to talk about
Whether to answer questions
How to spend time together
Who else is involved
Even tiny choices matter.
6. Go Slowly
People with disability have often been rushed, pushed, pressured.
Slow is respectful:
No pressure to disclose trauma
No timeline for healing
Following their pace, not yours
Time to process
Permission to say no, stop, or wait
7. Address Current Safety
If someone's currently unsafe, that's the priority.
Before trauma processing:
Address immediate safety concerns
Stable housing
Freedom from ongoing abuse
Basic needs met
Coping skills developed
Maslow before trauma therapy.
8. Recognise Intersections
Trauma doesn't exist in isolation.
Consider:
How does disability interact with trauma?
What other marginalisations exist (race, class, LGBTIQ+)?
What structural issues need addressing?
What supports exist or are missing?
Holistic understanding, not just individual symptoms.
9. Question "Behaviours of Concern"
Behaviour is communication.
When someone displays "challenging behaviour":
What are they communicating?
What need isn't being met?
What's triggering this response?
Is this environment traumatic?
Are we the problem?
Often, changing environment or approach changes "behaviour."
10. Advocate for System Change
Individual support can't fix systemic trauma.
Also needed:
Deinstitutionalisation
Ending restrictive practices
Better NDIS planning processes
Accessible trauma services
Training for disability workers in trauma
Addressing ableism everywhere
Trauma-informed practice must include advocacy.
Specific Considerations
For People with Intellectual Disability
Adaptations:
Concrete, simple language
Visual supports
Shorter sessions
Repetition and consistency
Focus on present and recent past (memory challenges)
Body-based and sensory approaches
Creative methods
Remember: Trauma is processed emotionally and somatically, not just cognitively. Verbal processing isn't essential.
For Autistic People
Adaptations:
Clear, direct communication
Predictable structure
Sensory considerations
Special interests as resource
Recognition that autism and trauma interact
No pressure for eye contact or social norms
Time to process
Note: Autistic people experience PTSD at higher rates and it presents differently.
For Non-Verbal People
Approaches:
Observe behaviour and body language
Use AAC consistently
Offer choices through visuals or technology
Partner with people who know them well
Body-based trauma work
Creative expression
Presume competence always
Non-verbal doesn't mean non-thinking or non-feeling.
For People in Institutional Settings
Reality: Institutional settings are often traumatic. Supporting healing while someone's institutionalised is difficult.
What helps:
Advocate for least restrictive options
Create islands of safety and choice within system
Build external relationships and connections
Document harm
Support self-advocacy
Work toward discharge if desired
Long-term goal: Deinstitutionalisation.
When You Can't "Fix" the Trauma
Reality check: You often can't fix trauma caused by decades of ableism and institutional harm.
What you can do:
Not cause more trauma
Be trustworthy in your relationship with them
Create moments of safety and choice
Witness their pain without trying to fix it
Advocate for better systems
Support their own healing at their pace
Healing isn't your responsibility to create. It's theirs to lead and yours to support.
Supporting Yourself
This work is hard.
Working with trauma in disability contexts means:
Witnessing profound injustice
Feeling powerless to change systems
Dealing with secondary trauma
Navigating broken services
Managing your own feelings
You need:
Trauma-informed supervision
Peer support
Boundaries
Self-care that actually works
Acknowledgment of difficulty
Time away when needed
You can't pour from an empty cup.
The Bigger Picture
Trauma in disability contexts isn't individual pathology.
It's predictable consequence of:
Ableist society
Institutional models of support
Power imbalances
Segregation and isolation
Violence and abuse
System failures
Addressing trauma requires addressing these root causes.
Individual trauma-informed support matters. But it's not enough.
We also need:
Deinstitutionalisation
Ending segregation
Rights-based disability support
Accessible trauma services
Addressing ableism
Supporting self-advocacy
Listening to people with disability
Nothing about us without us.
The disability community has been saying this for decades.
Time we listened.
Key Takeaways
People with disability experience trauma at much higher rates due to abuse, institutionalisation, medical trauma, ableism, and service-caused harm
Trauma and disability presentations often overlap; behaviour of concern is often trauma response
Standard trauma treatment often doesn't work because it's not designed for people with disability and assumes trauma is past
Trauma-informed disability support requires safety, accessible communication, choice and control, going slowly, and relationship-based healing
Behaviour is communication; question "challenging behaviour" rather than trying to eliminate it
Individual support can't fix systemic trauma; advocacy for system change is essential
Healing happens at the person's pace, not according to therapy timelines
Reflection Questions
How might trauma be presenting in the people with disability you support?
What assumptions do you make about capacity that might be trauma-impacted?
How trauma-informed is your service? What creates safety? What undermines it?
What systemic changes would reduce trauma for people with disability?
