Understanding Behaviour Through Change in Health Presentation in PBS: Noticing When Something Is Different

May 12, 2026

Positive Behaviour Support requires services to understand when behaviour may reflect a change in health presentation. The Positive Behaviour Support knowledge hub supports providers to connect behaviour, communication, proactive support, rights and reduction of restrictive practice.

In specialist services, understanding behaviour through PBS means asking whether something is different in the person’s sleep, appetite, movement, skin, continence, alertness, breathing, mood, pain signs or tolerance of normal routines.

This reflects PBS principles and values, because behaviour should not be separated from health, comfort and wellbeing. Strong services do not assume that a sudden change is simply behavioural. They notice difference, record clearly and escalate safely.

Concept Explained Clearly

Change in health presentation means the person is not showing their usual pattern of wellbeing, comfort or daily functioning. This may be subtle. A person may eat less, move differently, sleep more, refuse touch, seek more reassurance, become quieter, become more irritable or lose interest in routines they usually enjoy.

For people who communicate differently, behaviour may be the first sign that something is wrong. PBS teams need to understand baseline presentation so they can recognise change. Without a clear picture of what is usual, staff may miss early signs of illness, pain, infection, constipation, medication effects, fatigue or emotional distress.

Why It Matters in Real Services

When health changes are missed, staff may respond with behaviour strategies that do not meet the real need. They may increase prompts, reduce choices, continue routines or introduce restrictions when the person needs health assessment and comfort-based support.

This creates avoidable risk. Delayed health escalation can lead to deterioration, distress, hospital admission or safeguarding concern. Commissioners and CQC will expect providers to evidence that staff recognise changes in presentation, escalate concerns appropriately and link behaviour support with health monitoring.

What Good Looks Like

Strong services demonstrate that staff know the person’s normal presentation. Records describe baseline sleep, appetite, mobility, communication, mood, engagement, pain indicators and usual responses to support. Staff can then identify when something changes.

Good PBS practice combines behaviour observation with health awareness. Staff record observable detail, adapt routines safely, seek clinical advice where needed and review whether behaviour returns to baseline after treatment or support changes. This creates a clear line of sight from behaviour to health concern, from concern to action, and from action to outcome.

Operational Example 1: Reduced Mobility and Increased Refusal

Step 1 – Change noticed: A person in supported living began refusing to attend the kitchen for meals and became distressed when staff encouraged walking. This was unusual because they normally enjoyed choosing food from the fridge.

Step 2 – Baseline compared: Staff checked recent records and saw that the person had been walking more slowly, holding furniture for support and sleeping longer after lunch.

Step 3 – Support adapted: The team reduced unnecessary walking, offered meals closer to the person’s preferred chair and avoided repeated encouragement that increased distress.

Step 4 – Health escalation completed: The manager contacted the GP with clear observations about mobility, fatigue, appetite and behaviour change. Family were also asked whether they had noticed similar changes.

Step 5 – Evidence reviewed: A health issue was identified and treated. Refusal reduced as comfort improved, and the provider evidenced that behaviour change was linked to physical presentation rather than motivation.

Deepening the Understanding: Baseline Is the Starting Point

Health-related behaviour can only be recognised well when teams understand what is normal for the person. A quiet person becoming quieter may be significant. A highly active person sitting still for long periods may be significant. A person who usually accepts touch pulling away may be communicating discomfort.

Strong providers should be able to evidence how baseline information is gathered, reviewed and shared. This includes family insight, staff observation, health records, communication profiles and behaviour data. Baseline understanding turns vague concern into meaningful evidence.

The related article on seeing behaviour as communication in PBS reinforces why sudden changes in behaviour should be heard as possible communication about health, pain or unmet need.

Operational Example 2: Withdrawal and Reduced Appetite

Step 1 – Early concern: In a residential service, a person became withdrawn, ate less at dinner and stopped joining a preferred evening activity. No single incident occurred, so the change was initially seen as a quiet day.

Step 2 – Pattern gathered: The senior support worker reviewed three days of notes and found reduced appetite, lower engagement and increased time in bedroom. Night staff also reported unsettled sleep.

Step 3 – Immediate support: Staff lowered evening demands, offered preferred soft foods, monitored fluids and used the person’s health communication tool to check for discomfort.

Step 4 – Escalation route: The provider sought clinical advice and recorded temperature, bowel pattern, intake, sleep and presentation changes according to internal procedure.

Step 5 – Outcome evidence: A minor infection was treated. The person’s appetite and engagement returned gradually. The provider evidenced that low-level behaviour change prompted timely health action before crisis.

Systems, Workforce and Consistency

Health presentation must be understood across the workforce. If day staff notice reduced appetite but night staff do not pass on poor sleep, the full picture may be missed. Strong services use handovers, daily notes, health monitoring tools and supervision to connect information.

Managers should review whether staff record observable detail rather than vague phrases. “Not themselves” should be supported by clear evidence: what changed, when it changed, how often it happened and what staff did. Supervision should reinforce that behaviour and health are reviewed together.

Operational Example 3: Increased Irritability After Medication Change

Step 1 – Presentation shift: A person receiving outreach support became more irritable after a medication change. They refused usual community visits, snapped at staff and slept during the afternoon.

Step 2 – Context checked: The provider compared behaviour records with medication dates and found a clear timing link. Staff also recorded reduced alertness and lower appetite.

Step 3 – Support adjusted: Community visits were shortened, scheduled later in the day and paired with lower-demand activities while observations continued.

Step 4 – Clinical review requested: The provider shared structured evidence with the prescriber, including sleep, appetite, mood, refusal patterns and participation changes.

Step 5 – Impact evidenced: Following clinical review, support routines stabilised and participation improved. The provider evidenced that health presentation and medication context were considered before behaviour was labelled as deterioration.

Governance and Evidence

Governance should show how changes in health presentation are recognised, recorded and escalated. Providers should be able to evidence baseline profiles, health action plans, daily records, incident reviews, PBS plan updates, clinical liaison, supervision notes and outcome monitoring.

Strong governance connects behaviour to wellbeing. Records should show what changed, what staff observed, what action was taken, who was informed and whether outcomes improved. This creates a clear line of sight from behaviour to health presentation, from health presentation to escalation, and from escalation to outcome.

Commissioner and CQC Expectations

Commissioners expect providers to recognise health-related behaviour because it affects safety, stability and quality of life. They need assurance that services can distinguish behavioural patterns from changes that require health review.

CQC will expect safe, responsive and person-centred care. Inspectors may review whether staff recognise deterioration, escalate concerns, maintain accurate records and update support plans after health learning. Strong services demonstrate that health awareness is embedded in PBS delivery.

Common Pitfalls

Describing behaviour as sudden without checking health presentation.
Recording “not themselves” without observable evidence.
Missing low-level changes because no major incident has occurred.
Continuing normal demands when the person may be unwell or in pain.
Failing to connect night-time changes with daytime behaviour.
Not updating PBS plans after health-related behaviour patterns are identified.

Conclusion

Understanding behaviour through change in health presentation helps PBS teams respond safely and respectfully when something is different. Behaviour may be the first visible sign of pain, illness, medication effect, fatigue or discomfort.

Strong providers know baseline presentation, record change clearly and escalate through the right health routes. They evidence how behaviour, health observation, staff action and outcomes connect. This protects people’s wellbeing and gives commissioners and CQC confidence that PBS is clinically alert, person-centred and well governed.
