Understanding Behaviour in Positive Behaviour Support: Looking Beyond Incidents to Identify Causes
Understanding behaviour is one of the most important foundations of effective Positive Behaviour Support (PBS). High-quality PBS services do not focus only on managing incidents after they happen. Instead, they aim to understand why behaviour occurs, what the person may be communicating, and how support environments can be adapted proactively.
Within the wider Positive Behaviour Support (PBS) knowledge hub, understanding behaviour is recognised as central to reducing distress, improving quality of life and strengthening person-centred support.
This approach closely aligns with wider PBS principles and values and supports providers to move away from reactive behaviour management toward proactive, evidence-based support.
Why Understanding Behaviour Matters in PBS
In PBS, behaviour is not viewed as “challenging” in isolation. Behaviour is usually meaningful and often reflects unmet needs, distress, confusion, sensory overload, anxiety, communication difficulties or environmental pressures.
When services focus only on stopping behaviour, they risk missing the underlying causes entirely. This can increase frustration, damage trust and lead to more restrictive responses.
Strong PBS services instead aim to understand:
- what the person may be communicating
- what environmental factors influence behaviour
- how routines, relationships or sensory experiences affect wellbeing
- what proactive adjustments could reduce distress
This creates a more compassionate, rights-based and preventative approach to support.
Looking Beyond the Behaviour Itself
Behaviour is rarely random. Many incidents emerge from patterns that develop over time.
Common contributing factors may include:
- unmet sensory or emotional needs
- confusing or overwhelming environments
- lack of choice or predictability
- communication difficulties
- physical discomfort or health concerns
- changes in routine, staffing or environment
Understanding these factors allows providers to respond proactively rather than reactively.
Many of these themes are explored further within this guide to understanding behaviour as communication in PBS, which explains why behaviour should be analysed within the wider context of the person’s life and support environment.
The Importance of Functional Understanding
PBS focuses heavily on understanding the function of behaviour rather than simply describing what happened.
This means exploring questions such as:
- What purpose might the behaviour serve for the person?
- What happens immediately before behaviour occurs?
- What response follows the behaviour?
- What needs or feelings may be influencing the situation?
Functional understanding helps staff move from judgement toward curiosity and analysis.
This approach is central to effective understanding behaviour practice within PBS services and helps providers reduce avoidable escalation.
Using the ABC Framework in Daily Practice
One of the most widely used tools within PBS is the ABC framework:
- Antecedents: What happened before the behaviour?
- Behaviour: What exactly occurred?
- Consequences: What happened afterwards?
When used properly, ABC recording helps staff identify patterns rather than isolated incidents.
For example, staff may notice:
- behaviour occurs during noisy transitions
- specific routines increase anxiety
- certain communication approaches reduce distress
- particular staff responses unintentionally reinforce escalation
This type of analysis allows services to redesign support proactively.
Moving from Reactive to Proactive Support
Understanding behaviour should lead directly to preventative action.
Strong PBS services use behavioural understanding to:
- adapt environments proactively
- improve communication methods
- increase predictability and structure
- reduce sensory overload
- strengthen choice and control
- support emotional regulation
The aim is not to “control behaviour” but to improve quality of life and reduce situations that create distress.
Workforce Skills and Reflective Practice
Staff confidence and reflective practice are critical to understanding behaviour effectively.
Teams should be supported to:
- observe behaviour objectively
- avoid judgemental language
- recognise environmental triggers
- understand communication differences
- reflect on how staff responses influence situations
Strong providers encourage staff to become investigators and problem-solvers rather than disciplinarians.
Commissioner Expectations in PBS Services
Commissioners increasingly expect providers to demonstrate how behaviour is understood and analysed within support delivery.
They will often look for evidence of:
- functional behavioural understanding
- person-centred PBS planning
- incident trend analysis
- proactive trigger reduction strategies
- reduction in restrictive interventions
- continuous learning and review
Providers who evidence proactive understanding rather than reactive management are increasingly viewed as lower risk and more aligned with modern PBS expectations.
Using Behavioural Understanding in Tender Responses
Behavioural understanding is now a major feature within PBS tender evaluations.
Commissioners increasingly want providers to explain:
- how behavioural patterns are investigated
- how environmental triggers are reduced
- how staff use ABC analysis and reflective practice
- how PBS planning improves quality of life outcomes
Strong responses typically include operational examples showing how changes to communication, routines, staffing or environments reduced incidents successfully.
This demonstrates continuous learning, proactive support and genuine PBS implementation.
Reducing Restrictive Practice Through Understanding
Understanding behaviour is also central to restrictive practice reduction.
When providers understand why distress occurs, they are better able to:
- prevent escalation earlier
- adapt support proactively
- avoid crisis-driven interventions
- increase emotional safety and predictability
This supports safer, more ethical and more person-centred care.
Conclusion
Positive Behaviour Support begins with understanding. Behaviour should never be viewed separately from the person’s environment, communication, routines, relationships and emotional wellbeing.
Providers that embed behavioural understanding into daily practice are better positioned to reduce distress, strengthen quality of life and demonstrate effective PBS delivery to commissioners, regulators and families.
