Behaviour that challenges is one of the most complex areas of health and social care practice. It affects care workers, support staff, educators, family carers, and employers across a wide range of settings, from residential care homes to classrooms to home support roles.
This guide explains what the term means, why behaviour happens, and how to respond safely, and which qualifications can help build the knowledge and confidence to handle these situations well.
Short Summary
Behaviour that challenges refers to actions of such intensity, frequency, or duration that they put the safety of the person or others at risk, or seriously limit access to everyday life. The term is now preferred over “challenging behaviour” because it recognises that the behaviour is often a response to an environment or unmet need, rather than a problem that belongs to the individual. In health and social care, understanding why behaviour happens is the essential first step towards responding safely, respectfully, and effectively.

What Is Behaviour That Challenges?
The term “behaviour that challenges” describes behaviour of such intensity, frequency, or duration that the physical safety of the person or others is placed in serious jeopardy, or behaviour which is likely to seriously limit the use, or result in the person being denied access to, ordinary community facilities.
The definition originates from Professor Eric Emmerson’s work on challenging behaviour in people with learning disabilities and has been widely adopted across UK health and social care, including by NICE guidelines and the Royal College of Psychiatrists. The term encompasses a broad range of behaviours across many different conditions and settings. Crucially, it describes that behaviour as challenging, not the person, emphasising that behaviour is not the person’s fault but rather results from the interaction of personal and environmental factors.
According to Mencap and NICE guidance, approximately 5-15% of people with a learning disability display behaviour that challenges at some point, with prevalence rates varying across educational, health, and social care settings. The rates peak between ages 20 and 49 and are higher in people with more severe disabilities to develop behaviour that challenges, affecting around 2.16% of adults and 2.5% of children in the UK who have a learning disability.
Why Professionals Prefer This Term
The shift from “challenging behaviour” to “behaviour that challenges” reflects a meaningful change in how the sector understands the issue.
“Challenging behaviour” implies the problem lies with the person. “Behaviour that challenges” places the challenge where it often belongs: with the environment, the system, or the response around the person. Advocates for people with disabilities have long argued that many such behaviours are understandable responses to inflexible or unresponsive services, not symptoms of the individual themselves. This framing shifts the focus from managing a person to understanding their experience.
Challenging Behaviour vs Behaviour That Challenges
In modern UK Practices, “behaviour that challenges” is the preferred professional term. The NHS, NICE, and the Challenging Behaviour Foundation all use it in their guidance. Care workers and educators who understand this distinction are better positioned to approach incidents with the right mindset from the outset.
Why Behaviour Happens
Understanding the causes of behaviour that challenges is more useful than simply reacting to it. Behaviour rarely occurs without reason, and that reason is often communicative.
Behaviour as Communication
Many people who display behaviour that challenges have limited verbal communication. Behaviour becomes their most available way to express pain, fear, frustration, or an unmet need. A person who hits out during personal care may be communicating pain, fear, or sensory discomfort rather than aggression for its own sake. This principle is especially important in autism, learning disabilities and dementia.
Unmet Needs
Unmet physical, emotional, or social needs are among the most common triggers. These may include hunger, pain, loneliness, boredom, lack of meaningful activity, or the absence of consistent relationships. In care settings, rushed routine and high staff turnover can create conditions where needs go unmet and behaviour becomes the person’s only available signals.
Environmental Factors
Noise, crowding, unpredictable routines, unfamiliar people, and lack of personal space can all raise distress and increase the likelihood of behaviour that challenges. Environments that offer predictability, calm, and meaningful activity consistently reduce the frequency and severity of incidents.
Physical Health and Pain
Pain is one of the most frequently overlooked causes, particularly in people who cannot reliably communicate it. Dental problems, infections, constipation and medication side effects can all present as behavioural change. NHS guidance recommends that physical health causes should always be considered and ruled out before attributing behaviour to psychological or environmental factors.
Mental Health and Trauma
People with learning disabilities experience mental health conditions at higher rates than the general population, yet these are frequently underdiagnosed. This is sometimes called diagnostic overshadowing, where difficulties are attributed solely to the learning disability rather than investigated further. Many people who display behaviour that challenges also have histories of trauma, abuse, or neglect. Trauma-informed care creates environments of safety, trust, and choice, reducing the conditions in which distress-related behaviours are likely to be triggered.
Examples of Behaviour That Challenges
Behaviour that challenges can take many forms. Common examples include:
- Aggression towards others: hitting, biting, scratching, kicking, or verbal threats.
- Self-injurious behaviour: head-banging, self-biting or skin-picking
- Property damage: breaking objects, throwing items, or damaging the environment
- Withdrawal and refusal: refusing personal care, food, medication, or engagement
- Repetitive or stereotyped behaviour: rocking or vocalising, which may escalate when distressed.
- Visual outbursts: shouting, screaming, or persistent vocalisations
The same behaviour can have very different causes in different people. Effective support requires understanding the individual, not just identifying the behaviour.
Behaviour That Challenges in Different Settings
Learning Disabilities
Around 1.5 million people in the UK have a learning disability, according to Mencap. Among those with severe learning disabilities, behaviour that challenges is closely linked to communication difficulties, sensory differences, unmet needs, and mental health conditions. NICE estimates that 10 to 15% require specialist behaviour support. The most effective approaches combine communication support, person-centred care planning, and Positive Behaviour Support.
Autism
In autistic people, behaviour that challenges is frequently related to sensory overload, disrupted routines, or being in environments not designed for their needs. The National Autistic Society notes that what appears to be challenging behaviour is often a direct response to a challenging environment.
Extreme distress in autistic people can lead to a meltdown, which is an involuntary response in which the person has lost control of their reaction. This is not a tantrum. The response should focus on safety and reducing further sensory input, not discipline.
Dementia Care
According to the Alzheimer’s Society, around 90% of people with dementia will experience behavioural or psychological symptoms at some point, including agitation, aggression, wandering, and resistance to personal care. Research indicates that around 20% of incidents in dementia care occur around tasks such as bathing or dressing, most commonly caused by pain, fear, or confusion rather than deliberate intent. Consistent care relationships and person-centred approaches significantly reduce their frequency.
Residential Care, Home Care, and Education
Across all settings, the quality of the care relationship, built on trust, consistency, and genuine understanding of the person, is one of the most powerful protective factors. In education, training in behaviour that challenges helps staff recognise unmet needs ratherthan misreading them as defiance, which directly reduces the use of exclusion and punitive responses.
Positive Behaviour Support
What Is Positive Behaviour Support (PBS)
Positive Behaviour Support (PBS) is an evidence-based framework for understanding and responding to behaviour that challenges. It draws on applied behaviour analysis and person-centred values to develop individualised, proactive support plans. PBS is recommended as best practice by NICE, NHS England, and the British Institute of Learning Disabilities (BILD).
Core Principles of PBS
- Understanding before responding
PBS begins with a functional behaviour assessment to identify what purpose the behaviour is serving for the individual before any intervention is designed. - Proactive rather than reactive
The goal is to reduce the conditions that give rise to behaviour that challenges in the first place. This may mean changing the environment, adjusting routines, improving communication support, or addressing unmet health needs. - Person-centred values
Reducing behaviour that challenges is only meaningful if it also improves the person’s wellbeing, autonomy, and quality of life. - Reducing restrictive practices
PBS explicitly aims to reduce reliance on restraint, seclusion, and medication used to control behaviour, in line with NHS England’s Transforming Care Programme.
Why PBS Is Recommended in the UK
NICE guidelines (NG11) recommend PBS as the primary approach for assessment and intervention. The CQC expects providers to demonstrate evidence-based, person-centred approaches to behaviour support. Settings that rely on reactive or restrictive responses without a PBS framework risk failing inspection standards and, more importantly, risk failing the people they support.
Trained staff are less likely to escalate situations and better equipped to support independence rather than restrict it. Training in PBS directly supports the UK government’s policy priority of reducing restrictive practices across health and social care.

How to Respond Safely and Effectively
When a person displays behaviour that challenges, safety and dignity are always the priority.
- What to do
Stay calm, as your emotional state directly affects the person. Give space by increasing physical distance and reducing noise or other stimulation. Use short, clear sentences in the person’s preferred communication method. Acknowledge that the person is distressed without reinforcing the behaviour. If a behaviour support plan is in place, follow it. - What not to do
Do not use physical restraint except as an absolute last resort, in line with legal requirements and organisational policy. Do not raise your voice or adopt a confrontational posture. Do not attempt lengthy reasoning during an acute episode. - De-escalation and recording
Effective de-escalation involves recognising early warning signs, offering choices to restore a sense of control, using a calm tone and non-threatening body language, and allowing time. Research by BILD and Skills for Care consistently identifies de-escalation as one of the most effective tools available and a direct alternative to restrictive practices. Every incident should be recorded accurately and promptly to support care plan reviews, identify patterns, protect staff, and demonstrate to CQC inspectors that behaviour is being managed safely.

Frequently Asked Questions (FAQs)
What is the behaviour that challenges?
Behaviour that challenges refers to actions of such intesity, frequency, or duration that they place the safety of the person or others at risk, or seriously limit access to ordinary community life. The term is used across UK health and social care to describe a wide range of behaviours in many conditions and settings.
Is behaviour that challenges the same as challenging behaviour?
The behaviours described are the same, but the terms carry different meanings. “Challenging behaviour” implies the problem belongs to the person. “Behaviour that challenges” recognises that the challenge often lies in the environment, the system, or the response around the person, a distinction that shapes how support is designed and delivered.
What causes behaviour that challenges?
Common causes include unmet needs, communication difficulties, pain, mental health conditions, environmental triggers, and trauma histories. Understanding the specific cause for an individual is the starting point for effective support.
How should carers respond?
Stay calm, give space, use simple communication, follow the individual’s support plan, and avoid confrontational responses. De-escalation is the primary goal. Physical restraint is a last resort, used only within legal and organisational guidelines.
Is the behaviour that challenges in behaviour linked to autism?
Yes. It is frequently related to sensory overload, disrupted routines, or communication difficulties. Extreme distress can result in a meltdown, which is an involuntary response rather than a tantrum, and requires a calm, safety-focused response rather than discipline.
Is behaviour that challenges linked to dementia?
Yes. Around 90% of people with dementia will experience behavioural or psychological symptoms at some point, most commonly caused by pain, confusion, fear, or unmet needs. Person-centred care and consistent relationships are the most effective responses.
What qualifications help with behaviour support?
The Level 2 Understanding Behaviour that Challenges qualification, awarded by NCFE CACHE and regulated by Ofqual, is the most directly relevant. It covers causes, triggers, communication, de-escalation, and post-incident reflection, studied online at your own pace.
