Reasonable Adjustments in Positive Behaviour Support: What They Are and Why They Matter
Some of the most powerful work in Positive Behaviour Support does not look like therapy at all. It looks like changing the environment around a participant so the behaviours of concern have less reason to happen in the first place. Softer lighting. Clearer routines. Warning before transitions. A visual schedule on the wall. A quieter meal time. These changes are called reasonable adjustments, and they are often where the real work of PBS lives.
This blog explains what reasonable adjustments are in Positive Behaviour Support, how they connect to the broader clinical framework, and why they matter for participants, families and Support Coordinators.
What Reasonable Adjustments Are in PBS
A reasonable adjustment is a change to the environment, routine, communication or expectations around a participant, designed to make daily life more accessible and less distressing. In Positive Behaviour Support, reasonable adjustments are often the primary intervention, not an add-on.
Common examples include:
- Environmental changes such as reducing sensory load, providing quiet spaces, adjusting lighting or seating.
- Routine changes such as adding predictability, providing warnings before transitions, or building in rest periods.
- Communication adjustments such as using visual schedules, augmentative and alternative communication tools, or simpler language.
- Expectation adjustments such as removing tasks that exceed the participant's capacity in that moment, or adjusting timing.
- Relational adjustments such as ensuring the participant is supported by staff they trust, or slowing the pace of new introductions.
Each of these looks like a small change. Taken together, they can transform a participant's daily experience.
Why Reasonable Adjustments Matter Clinically
The clinical case for reasonable adjustments is straightforward. Behaviours of concern are often responses to environments or expectations that do not fit the participant. When the environment changes, the behaviour changes too.
This approach reflects the core PBS principle that behaviour is communication. If a participant is telling us, through their behaviour, that the environment does not work for them, the most effective response is often to change the environment rather than to change the participant. Person-centred, evidence-based and dignified.
This also connects directly to restrictive practice reduction. When reasonable adjustments meet the participant's underlying needs, the drivers of restrictive practice use tend to reduce as well. Reasonable adjustments are one of the most important tools in the Positive Behaviour Support approach to reducing and eliminating restrictive practices over time.
Who Implements Reasonable Adjustments
Reasonable adjustments are implemented by the people around the participant every day. That includes family, support workers, SIL staff, day program staff, educators and any other regular contact. The Behaviour Support Practitioner identifies which adjustments are needed and trains the team on how to apply them consistently.
Where reasonable adjustments involve sensory or physical modifications to the home, Occupational Therapy input often strengthens the plan. Where they involve communication supports or AAC devices, speech pathology may be involved. This is another example of why coordinated multi-disciplinary care matters for participants with complex needs.
What Reasonable Adjustments Look Like in Practice
Two brief and generic examples show how reasonable adjustments can change daily life:
A young person whose mornings are consistently distressing may benefit from a visual schedule, a fixed order of tasks, and the removal of demands until they are regulated. Behaviours of concern that were happening every morning start to reduce as the environment matches what the young person can manage.
An adult who becomes overwhelmed by loud environments may benefit from noise-cancelling headphones, planned rest periods, and rearranging shared living spaces to reduce noise from other residents. Community participation improves because the participant is no longer operating from a state of dysregulation.
For Support Coordinators
For Support Coordinators, understanding reasonable adjustments matters because they are often the fastest, most cost-effective intervention in a PBS engagement. They also require the support team around the participant to actually implement them consistently, which is where communication with the participant's PBS Practitioner and other providers is essential.
