Behaviours that are labeled 'of concern' often make sense when you understand the person's history. Someone who hits others may have experienced violence. Someone who refuses to go out may have had a traumatic experience in public. Someone who self-harms may be managing overwhelming emotions the only way they know how.
Trauma-informed behaviour support starts with the question 'what happened to you?' rather than 'what's wrong with you?', and builds strategies around understanding and addressing the underlying distress, not just suppressing the behaviour. For NDIS participants, this shift from restraint-focused to strength-focused, trauma-aware support can be genuinely transformative.
Understanding Behaviour as Communication
Challenging behaviours are almost always a form of communication or coping. They're often the person's best attempt to manage overwhelming emotions, sensory input, pain, fear, or unmet needs when they don't have other tools available. Behaviour is never random; it's always trying to do something for the person.
When someone hurts themselves or others, refuses tasks, or has a meltdown, these are signs of distress. The behaviour is the visible part; the real work is understanding what's driving it. Is the person in pain? Overwhelmed sensorily? Triggered by something in the environment? Trying to communicate something they can't say in words?
How Trauma Shapes Behaviour and Regulation
People who've experienced trauma—whether physical abuse, neglect, medical trauma, or repeated frightening experiences—develop nervous systems that are primed to perceive threat. Their threshold for stress is lower, their startle response faster, and their ability to calm themselves often damaged. What looks like 'overreacting' is actually a nervous system doing its job, protecting against threat the way it learned it had to.
Restrictive practices—restraint, seclusion, forced compliance—can retraumatise people with trauma histories. They reinforce the message that their body isn't safe, that adults will overpower them, and that their distress doesn't matter. Trauma-informed approaches recognise this and build safety and trust instead.
Trauma-Informed Behaviour Support in Practice
Trauma-informed behaviour support involves: creating predictability and safety in the environment; teaching emotion regulation and calming skills; understanding triggers and avoiding unnecessary activation of the nervous system; responding to distress with compassion rather than punishment; and involving the person in planning their own support whenever possible.
Staff training is crucial. Support workers need to understand trauma responses, avoid triggering situations, recognise their own stress responses so they don't escalate situations, and build relationships of trust rather than just compliance. The goal is a regulated, safe person, not a compliant one.
Positive Behaviour Support and Moving Away from Restriction
Positive Behaviour Support (PBS) is an evidence-based framework that sits comfortably with trauma-informed practice. Rather than focusing on what behaviour to suppress, PBS focuses on teaching the skills the person needs, making it easy for them to succeed, and responding to behavioural challenges with problem-solving rather than punishment.
This includes looking at the environment itself: Is it too noisy? Too crowded? Too unpredictable? Are there unmet needs—hunger, tiredness, social connection, autonomy—that are driving behaviour? Often, changing the environment or meeting the underlying need eliminates the behaviour entirely without any behaviour plan at all.
Frequently Asked Questions
Is trauma-informed behaviour support just 'being nice'?
No, it's highly structured and evidence-based. It involves systematic assessment of triggers and needs, explicit skill teaching, environmental design, and consistent implementation—it's just focused on understanding and building skills rather than punishment.
What if the behaviour is dangerous?
Safety is always important. Trauma-informed practice addresses safety by understanding what's driving the dangerous behaviour, teaching alternatives, and preventing triggers when possible. This usually reduces dangerous behaviour faster than restriction does.
Can restrictive practices ever be necessary?
Restrictive practices should be a last resort and minimal. Even when necessary for immediate safety, they should be paired with trauma-informed support to address the underlying cause, otherwise the behaviour returns when restriction ends.
Trauma-informed behaviour support rests on a simple principle: people behave better when they feel safe, understood, and supported. Tenax's behaviour support team uses trauma-informed and positive behaviour support approaches that help participants develop the skills they need while building trust and safety.
