Understanding Behaviour in PBS: It’s Not About What You See — It’s About Why It’s Happening

Positive Behaviour Support (PBS) starts with understanding — not reacting. At its best, PBS is a disciplined, values-led way of working that turns curiosity into safer, more person-centred support. That is why teams need to stay grounded in PBS principles and values and apply ethical PBS frameworks when decisions feel urgent. Understanding must come before intervention — otherwise services risk escalating restriction, damaging relationships, and missing what the behaviour is communicating.


Too often, behaviours that challenge are seen as something to stop, reduce, or manage. But PBS reframes the question entirely. It asks: What is this behaviour communicating? What is the person trying to achieve, avoid, or express that they may not be able to put into words?

This shift — from behaviour as ‘problem’ to behaviour as ‘communication’ — is the foundation of PBS. Without it, any support strategy risks missing the point. You may reduce incidents temporarily, but you may also increase distress, reduce autonomy, and drive behaviour into more intense or risky forms.


🔍 What It Means to Understand Behaviour

Understanding behaviour is not guesswork. In PBS, it means building a credible, testable explanation of what is happening and why. That explanation should lead to proactive adjustments in the person’s support and environment.

  • Look for patterns — What happens before and after the behaviour? When does it occur, where, and with whom?
  • Consider unmet needs — Is the person bored, overwhelmed, in pain, anxious, hungry, tired, or misunderstood?
  • Think holistically — What is the person’s history, trauma exposure, sensory profile, communication style, and preferred way of engaging?

Understanding behaviour requires observation, curiosity and time. But it pays off — because the right support only follows from the right understanding. In practice, strong functional understanding reduces crisis cycles, stabilises placements, and lowers reliance on restrictive interventions.


📌 Commissioner expectation

Commissioner expectation: commissioners typically expect providers to demonstrate that behaviour support is function-based, proactive and outcome-led. In practical terms, this means being able to evidence: (1) how functional assessments inform support plans, (2) how proactive strategies are implemented consistently across shifts, and (3) how impact is measured beyond “incident reduction”, including quality of life, engagement, stability and reduced restrictive practice over time.


🔎 Regulator / Inspector expectation (CQC)

Regulator / Inspector expectation (CQC): inspectors will look for person-centred, safe and least restrictive practice. They will expect staff to be able to explain the person’s triggers, needs and early warning signs, and to show that support is adjusted proactively. If restrictive interventions are used, inspectors will expect clear rationale, review, and evidence that less restrictive alternatives are explored and strengthened first.


🧠 What Behaviour May Be Communicating

Behaviour is often a person’s best available strategy in the moment. It may communicate discomfort, fear, loss of control, overwhelm, or unmet needs. Common underlying drivers include:

  • Health and pain: toothache, constipation, infection, reflux, headaches, menstrual pain, medication side effects.
  • Sensory overload: noise, lighting, crowding, touch, smells, visual clutter or unpredictable movement.
  • Communication breakdown: the person does not understand what is expected, or staff do not understand the person’s signals.
  • Demand and control: tasks are too hard, too fast, too many steps, or offered without meaningful choice.
  • Anxiety and trauma cues: certain tones, approaches, environments or routines trigger fear responses.
  • Social needs: lack of predictable connection, loneliness, insecurity about attention or reassurance.

The aim is not to “explain away” behaviour. The aim is to respond in a way that makes the behaviour less necessary because the person’s needs are met more effectively.


🚫 Why Surface-Level Labels Fall Short

Terms like “aggressive”, “non-compliant”, or “disruptive” can be misleading and sometimes harmful. They tell us what happened — but nothing about why. Worse, they can shape negative perceptions that influence how staff interact with a person going forward, which can intensify distress.

Descriptive, neutral language helps teams remain objective, reduce bias, and stay focused on solutions. Instead of “aggressive”, record what happened: “hit staff member’s arm when asked to leave the room; then moved to doorway; raised voice; paced; stopped after staff reduced demands and offered quiet space.” That detail is what makes functional understanding possible.


📋 Functional Assessment: Turning Curiosity Into Evidence

PBS uses functional assessment to build a practical understanding of behaviour. This can include ABC charts, incident mapping, routine analysis, and structured observations. Done well, it is not paperwork — it is the mechanism that links behaviour to proactive support.

A high-quality functional assessment typically captures:

  • Setting events: what changed earlier that day/week (sleep, illness, staffing, routine disruption, family contact, trauma reminders).
  • Antecedents: the immediate triggers (requests, transitions, denied access, noisy environments, crowded spaces).
  • Behaviour description: what occurred, duration, intensity, escalation path and recovery.
  • Consequences: what changed afterwards (demands removed, attention provided, access gained, sensory relief, escape achieved).

The outcome should be a clear working hypothesis about the behaviour’s function, which the team then tests by making planned adjustments and observing whether behaviour changes.


🧩 Operational example 1: “Refusal” as overload and loss of control

Context: A person repeatedly refuses personal care tasks and becomes distressed when staff prompt. Incidents escalate when multiple prompts occur or staff insist on immediate compliance.

Support approach: Functional assessment suggests the behaviour functions to avoid overwhelming demands and regain control. The issue is not “refusal” but how demands are presented and paced.

Day-to-day delivery detail: Staff switch to single-step prompts, provide processing time, use a visual routine, and offer meaningful choices (“now or in 10 minutes”). The environment is prepared to reduce sensory discomfort (warm room, preferred toiletries). Staff agree a “pause and reset” approach when early indicators appear.

How effectiveness is evidenced: Distress episodes reduce, engagement improves, and incident duration shortens. Evidence comes from incident logs, daily notes reflecting proactive strategies, and supervision records showing consistent application across staff.


🧩 Operational example 2: “Aggression” as pain and communication breakdown

Context: A person hits out during meal times and staff interpret this as targeted aggression. Incidents increase across two weeks with no obvious environmental changes.

Support approach: PBS review includes health checks and identifies untreated dental pain. The behaviour functions as escape from discomfort and intrusive support attempts.

Day-to-day delivery detail: Staff reduce physical prompting, offer softer foods temporarily, use calm, predictable communication, and support urgent dental access. Meal time demands are reduced, and the person is offered a quiet space option without conflict.

How effectiveness is evidenced: Incidents reduce after pain is addressed. The service updates the health action plan and PBS plan to include early indicators of discomfort and a protocol for health escalation when behaviour patterns change suddenly.


🧩 Operational example 3: “Attention seeking” as predictable reassurance need

Context: A person repeatedly shouts for staff and escalates when ignored. Staff respond by setting firm boundaries and reducing engagement, which increases distress.

Support approach: Assessment suggests the behaviour functions to access reassurance and connection, especially during busy periods. The person lacks a predictable way to get attention safely.

Day-to-day delivery detail: The service introduces planned check-ins at set times, uses a visual “when staff are available” cue, and supports the person to request connection using a prompt card or phrase. Staff respond consistently with brief reassurance and a time cue rather than extended conflict.

How effectiveness is evidenced: Shouting reduces as reassurance becomes predictable. Evidence includes frequency tracking, staff notes on successful strategies, and improved stability during peak demand periods.


📋 How to Show Understanding in Tenders and Inspections

This is where services can stand out. Commissioners want to see that you don’t just react to behaviour — you seek to understand it and translate that understanding into consistent support.

  • Explain how you complete functional assessments or ABC charts, including quality checks and review intervals.
  • Describe how staff are trained and supervised to spot triggers, early indicators and setting events.
  • Give examples of how deeper understanding led to improved support — not only fewer incidents, but improved quality of life, participation and placement stability.
  • Explain how restrictive practice reduction is governed (registers, reviews, least restrictive rationales, learning loops).
  • Describe how outcomes are measured (frequency, duration, recovery time, engagement indicators, independence goals).

Strong tender responses make this auditable: incident → analysis → hypothesis → proactive change → review → outcome evidence.


💡 The Takeaway

Behaviour is not the issue — it’s the clue. When we understand behaviour through a PBS lens, we stop asking “How do we stop this?” and start asking “What does this person really need, and what must we change in our support and environment?”

That shift strengthens outcomes for the person and strengthens the provider’s governance position, because it demonstrates prevention, least restrictive decision-making, and a credible evidence trail — exactly what commissioners and inspectors expect to see.
