Challenging behaviour and positive behaviour support at home

When an adult with a learning disability hits out, hurts themselves or refuses everything, the behaviour is almost always telling you something the person cannot say another way. This guide covers why pain is checked first, how a positive behaviour support plan is put together and who writes it, the rules on restrictions and medication, and where a family can turn for help.

What the behaviour says

Behaviour that challenges is usually the person telling you something

Hitting, biting, screaming, breaking things, running off or hurting themselves can be frightening to live with. The Challenging Behaviour Foundation is clear that it is the behaviour which is described as challenging, not the person, and that challenging behaviour is not a diagnosis.

What you see

  • Hitting, kicking or biting
  • Shouting or screaming
  • Hurting themselves
  • Breaking or throwing things
  • Running off
  • Refusing everything

“Something hurts, or I feel ill”

Toothache, constipation, reflux, an ear or urine infection, seizures, or the side effects of a medicine. Pain is easy to miss when somebody cannot say where it is.

What helps: A GP appointment comes first, especially if the change was sudden.

“It is too loud, too bright or too busy”

Noise, crowds, strong smells, heat, or a room with too much going on. What calms one person can be unbearable for another.

What helps: Note where and when it happens. Quieter times, headphones or a way out of the room can go into the plan.

“Something has changed and I do not understand it”

A new carer, a move, a brother or sister leaving home, a bereavement, or a day that did not go the way it was meant to.

What helps: Explain what is going to happen before it happens, in the way the person understands best, and keep the rest of the day the same.

“There is nothing for me to do”

Long empty stretches, or activities chosen for the person rather than with them. NICE lists low engagement among the things that raise the risk.

What helps: A planned day built around what the person enjoys, adjusted with them and their family when it is not working.

“You are not understanding me”

Signs, sounds or pictures that the people around the person do not recognise, or being asked too much in too many words.

What helps: A speech and language therapist can help set up a clear way to ask for a drink, say no, or say finished.

“I want something, or I want this to stop”

The Challenging Behaviour Foundation describes four common purposes: company or attention, getting something, getting away from something, and the sensation itself.

What helps: Once the purpose is clear, the plan teaches another way to get the same thing, one that works as well for the person.

The same behaviour can mean different things on different days. Working out which is the job of a functional assessment. Drawn from the Challenging Behaviour Foundation's information sheets and NICE guideline NG11.

NICE guideline NG11, which covers behaviour that challenges in people with a learning disability, asks everyone involved, family included, to understand that the behaviour often indicates an unmet need, and that the way people respond to it can keep it going. That second point is hard to hear, and it is not a criticism. It means the answer usually lies in changing things around the person rather than changing the person, which NICE sets out as the aim of any support.

A person may have few or no words, and even someone who talks well may not be able to explain pain or fear when it matters. The Challenging Behaviour Foundation describes the behaviour as something people learn to use because it has worked before, not as something deliberate. If hitting out once got a noisy room emptied, it is likely to happen again the next time the room is noisy.

NICE lists the things that make it more likely, including autism, communication difficulties, physical health problems, too much or too little going on, and changes such as new staff or a move. If your son or daughter is autistic, autism support at home covers the sensory side and meltdowns in more detail, and the learning disability family guide is where to start on everything else. The disability care pillar has the wider picture of support at home.

Rule out pain first

Check for pain and illness before anything else

The Challenging Behaviour Foundation's advice is that the first thing to check when behaviour suddenly gets worse is the person's health. Common conditions such as ear infections, toothache, constipation, urinary infections and epilepsy can all cause it.

Physical causes to raise with the GP

Pain that is easy to miss

Bowels, bladder and seizures

Everything else the GP should look at

The Challenging Behaviour Foundation warns about diagnostic overshadowing, where the behaviour is put down to the learning disability and the health problem underneath is missed. If you think that is happening, ask what has been ruled out. You know how your son or daughter shows pain, and that knowledge is evidence.

Anyone aged 14 or over on the GP's learning disability register can have a free annual health check, and NICE asks for it to include a review of any behaviour that challenges and how it may link to a physical health problem. The annual health check explains how to get the most from it. Write down how the person shows pain in the hospital passport too, so that anyone treating them in hospital can read it.

The functional assessment

How a functional assessment works out what the behaviour is for

Once physical causes have been looked at, a professional works with the family to find out what the behaviour does for the person. NICE calls this a functional assessment, and it is the base for any plan.

  1. 1

    Describe the behaviour clearly

    With the family
    What it looks like, how often, how long it lasts, and what effect it has on the person and those around them. You will be asked because you see it most.
  2. 2

    Keep a record for a few weeks

    At home
    A simple chart of what happened just before, what the behaviour was, and what happened straight after. Patterns show up over a few weeks that nobody notices on the day.
  3. 3

    Look for slow triggers and quick ones

    The build-up
    The Foundation calls poor sleep, hunger or feeling ill setting events, because they make a person less able to cope. A trigger is the thing that happens just before.
  4. 4

    Watch a typical day

    Where it happens
    The professional may come and observe at home. The Foundation suggests inviting them on an ordinary day, without extra help or fewer demands, so they see what you see.
  5. 5

    A written explanation of why

    The result
    NICE calls this a formulation: a written statement of what has led to the behaviour and what purpose it serves. The plan is built from it.

NICE asks for the assessment to be proportionate: a short one for behaviour that has started recently, and a fuller one where the behaviour is severe or has not responded to a first plan. The person stays at the centre of it, and the family should be fully involved and told how they will hear the outcome.

Some behaviour has more than one purpose, and for some people the reasons stay unclear even after a careful assessment. The Challenging Behaviour Foundation's view is that a plan based on a best guess is still worth having, because everyone then responds in the same way. Its information sheet Finding the reasons for challenging behaviour has examples of recording charts a family can use.

What the plan contains

What a positive behaviour support plan contains

A positive behaviour support plan, often called a PBS plan or a behaviour support plan, is a written document built on the functional assessment. Most of it is about making good days more likely, and what to do when things go wrong comes last.

How distress rises and falls, and where each part of the plan applies

GreenAmberRedAfterwards
  1. GreenMost of the time

    Keep the person settled, busy and understood

    What a good day looks like, what the person enjoys, how they communicate, and the changes to surroundings and routine that make distress less likely. It also sets out a skill to teach, such as a sign or a picture card that does the job the behaviour was doing.

    A line a plan might holdShow the day's plan on the picture board at breakfast. A walk to the shop before lunch. The radio off when visitors come.
  2. AmberEarly warning signs

    Notice it building and help the person back to calm

    The small signs that the person is becoming anxious or upset, which the family often know best, and what to do for each one: a change of activity, a quieter room, something the person likes, fewer words.

    A line a plan might holdLouder humming and pacing means the room is too busy. Offer the garden and stop asking questions.
  3. RedAt the height of it

    Keep everyone safe with the least restriction

    What to do if the behaviour happens anyway: giving space, moving other people away, and what not to do. If a restriction is included, the plan says exactly what it is, when it may be used and by whom, and that it comes last.

    A line a plan might holdStep back and give plenty of space. Move other people out of the room. Speak little, and calmly.
  4. AfterwardsCalming down

    Help the person recover, then learn from it

    How to help the person settle, bearing in mind that distress can rise again for a while, and how to write down what happened so the plan can be reviewed.

    A line a plan might holdA quiet drink and no talk about it for an hour. Write down what happened just before, and what helped.

Every plan should also say

  • Who delivers the plan, and one named person who coordinates it
  • Any training the family or support workers need to follow it
  • How progress is recorded, so everyone can see whether it is working
  • Reviews every fortnight for the first two months, then monthly
The four phases follow the Challenging Behaviour Foundation's description of a plan. The list below them and the review timings come from NICE guideline NG11, recommendation 1.6.1. Every plan is written for one person.

NICE guideline NG11 says the plan should improve the person's quality of life and remove the conditions likely to lead to the behaviour, such as noise or an unpredictable day. It should help the person learn another way to get the same result, such as a sign for "I want to stop", and say how to calm them at the first signs of distress, before it covers what to do if the behaviour cannot be prevented.

NICE also asks for the plan to fit the abilities and resources of the family and staff who will use it, so you can say that part of a plan will not work in your house and ask for it to be changed. A good plan can be read by a new support worker on their first morning.

The Challenging Behaviour Foundation has family information sheets on each stage, and BILD, the British Institute of Learning Disabilities, has information on positive behaviour support.

Who writes it

Who writes the plan, and how to ask for one

A plan is written by professionals with the person and the family, not by a support worker on their own. The route to one usually runs through the GP or the council to a specialist team.

The community learning disability team

A local team that can include psychologists, psychiatrists, learning disability nurses, speech and language therapists and occupational therapists. Ask the GP or the council's adult social care team for a referral.

NHS and council

A PBS practitioner or psychologist

Usually the person who does the functional assessment and writes the plan with you. Ask who this will be, and how you will be involved.

Carries out the assessment

A named worker

NICE guideline NG93 recommends one named practitioner, such as a social worker or community nurse, who gets to know the person and coordinates their support over the long term.

Coordinates everything

The person and the family

NICE asks for both to be involved in developing and delivering the plan. You know what works on a bad morning, and that belongs in the plan.

At the centre

How to askSection titled How%20to%20ask

Ring or write to the GP and to the council's adult social care team and say, in these words, that your son or daughter has a learning disability and behaviour that challenges, and you are asking for a referral to the community learning disability team for a functional assessment and a behaviour support plan. Put the date on it, keep a copy, and describe two or three recent incidents with what happened before each one. If there is no Care Act assessment in place, ask for one at the same time. If your son or daughter is not yet 18, the transition at 18 explains how children's and adults' services hand over.

NICE guideline NG93, on how these services should be designed, says specialist behaviour support should be available in the community so that people can stay where they live, and that local waiting times should not exceed NHS standards. If you are told the wait is long, ask what support is available in the meantime and who to ring if things get worse.

Restrictions and medication

Restrictions and medication must be the least restrictive option, and written down

Two things families worry about most are being asked to restrict the person, and medication being used to calm them. The law and NICE guidance set limits on both, and it helps to know what they are.

What it covers

Restrictive practices
Anything that limits a person's rights or freedom of movement: locked doors, rooms they cannot go into, holding them, or sedation.
Medication for behaviour
Mostly antipsychotics, which are not a first-line treatment for behaviour that challenges.

When it may be used

Restrictive practices
Only as a last resort, alongside the proactive parts of the plan, starting with the least restrictive option.
Medication for behaviour
Only if other support has not worked in an agreed time, or the risk is very severe, and always alongside other support.

Who decides

Restrictive practices
Planned in advance with the person and family where possible, within the Mental Capacity Act.
Medication for behaviour
Started by a specialist, a psychiatrist, with the target behaviour and how it will be measured written down.

What gets recorded

Restrictive practices
Every use, what happened, and a plan to reduce the need for it.
Medication for behaviour
Why it was prescribed, for how long, and how it will be reviewed and stopped.

When it is reviewed

Restrictive practices
Regularly, discussed with the family and the person.
Medication for behaviour
After three to four weeks, and stopped if there is no sign it is helping by six weeks.

From NICE guideline NG11, recommendations 1.8 and 1.9, and section 6 of the Mental Capacity Act 2005.

RestrictionsSection titled Restrictions

Under section 6 of the Mental Capacity Act 2005, restraining someone who lacks capacity is only protected where the person doing it reasonably believes it is necessary to prevent harm to them, and the response is proportionate to how likely and how serious that harm is. Restraint in the Act includes restricting someone's movement whether they resist or not, so a locked kitchen door counts. NICE adds that every use should be documented, reviewed with the family, and matched by a programme to reduce it.

If the restrictions around someone at home add up to a deprivation of their liberty, that needs legal authorisation. The Social Care Institute for Excellence explains that outside care homes and hospitals this comes from the Court of Protection. Raise it with the social worker if you think it applies. Making decisions for a grown-up son or daughter covers capacity and best interests more widely.

Medication and STOMPSection titled Medication%20and%20STOMP

STOMP stands for stopping over-medication of people with a learning disability and autistic people. The NHS England programme aims for psychotropic medicines to be used only for the right reason, at the right dose and for as short a time as possible. NHS England says people with a learning disability are thought to be 15 times more likely than the general population to be prescribed an antipsychotic. You can ask for a medication review at any time, and the annual health check includes one. Reasonable adjustments, the dentist and STOMP has the questions to ask. Do not stop a medicine yourself: reducing it is done slowly, with the prescriber.

Family and crisis help

Help for the family, and what to do if things reach a crisis

Living with behaviour that challenges is tiring, and asking for help is not a sign of failing. NICE guidance says families should be told about their right to a carer's assessment, short breaks, and support in an emergency.

Ongoing supportWhen things are getting worse
  1. Now

    A carer's assessment and short breaks

    The council must assess a carer who appears to need support. NICE guideline NG93 asks for short breaks close to home, available at short notice.

  2. Now

    Support from other families

    The Challenging Behaviour Foundation runs support for families of people with severe learning disabilities, and NICE recommends family support groups and skills training.

  3. Building

    Ask for the plan to be reviewed

    If incidents or restrictions increase, or the person's quality of life drops, NICE says the plan should be reviewed. Ring the named worker or the learning disability team.

  4. Building

    Ask about the dynamic support register

    A local list of people at risk of going into hospital without the right support. The person has to agree to be on it.

  5. Crisis

    The crisis number, or 999

    Ask the team now for the out-of-hours crisis number, and write it in the plan. If anyone is in immediate danger, ring 999.

  6. Hospital

    A care and treatment review first

    If admission to a mental health or learning disability hospital is suggested, ask for a community care and treatment review to look at every other option.

A carer's assessment looks at your own needs, separately from your son's or daughter's, including whether you can keep caring and whether you want to. Short breaks are often what makes the rest possible, and respite for parents of a disabled adult covers the forms a break can take. If the question is longer-term, when the parents can no longer cope sets out how to plan for it. The Challenging Behaviour Foundation is the charity specifically for families in this position, and it is worth contacting before things reach a crisis.

The dynamic support register and care and treatment reviewsSection titled The%20dynamic%20support%20register%20and%20care%20and%20treatment%20reviews

NHS England's dynamic support register and Care (Education) and Treatment Review policy aims to keep people out of hospital when the right support at home would do it. The register rates each person's risk so that help goes where it is needed first. A care and treatment review (a care, education and treatment review for under-18s) is an independent meeting with a chair, a clinical expert and an expert by experience, who look at whether the person's care is right. NHS England says anyone can ask for one, including family, and that saying no to one will not affect the care the person receives.

NICE guideline NG93 says a person should only be admitted to hospital if their needs cannot be met safely in the community and every other possibility has been considered and exhausted, and that if admission is being discussed, the person and their family should be part of that discussion.

Where a support worker fits

Where a support worker fits: consistency, and following the plan

A plan only works if the people around the person follow it the same way every day. That is where a regular support worker helps most, and it is why the same one or two people over months matter more than who is free on the day.

Before you choose a support worker

0 of 6 ticked

Share the plan and ask about it

Agree how it will work

PrimeCarers is an introductory service, not an agency, and it has no CQC registration. The family, or the person themselves, chooses the carer, interviews them first, and agrees the hours and routine directly with them, and they can keep working together for as long as it suits both of them. For someone who relies on a familiar face and a routine that does not change, that choice matters. You can search for carers near you, compare their rates and interview them before deciding.

There is no way to search for carers by positive behaviour support training or learning disability experience, and we do not check qualifications, training or references. What a carer says about their experience is their own account on their profile, so check it with them, using the questions to ask at interview. Before a carer appears in a search we check their identity and right to work, confirm an enhanced DBS check (or PVG in Scotland, Access NI in Northern Ireland) issued within the last 18 months, and interview them online. Separately, carers are insured while they work. How we vet every carer sets this out.

Carers on PrimeCarers charge £18 to £25 an hour with our fee included, against £28 to £35 at an agency. A council direct payment can be used to pay for support the person chooses, and direct payments and personal assistants and direct payments explain what a council will and will not accept. Any clinical task, such as rescue medication for seizures, is arranged and trained with the clinical team, as what carers are not allowed to do explains.

Questions

Questions families ask about challenging behaviour

The main guideline is NICE NG11, published in 2015. It asks for physical and mental health causes to be looked at, a functional assessment to understand what the behaviour is for, and a written behaviour support plan built on it. It says restrictive interventions are a last resort, and that antipsychotic medication should only be considered in limited circumstances and always alongside other support. A second guideline, NG93, covers how services should be organised.

Every plan is written for one person, but most follow the same shape. The green part describes a good day and what keeps the person settled, such as showing the day's plan on a picture board at breakfast. The amber part lists early warning signs and what to do, such as offering a quieter room. The red part says how to keep everyone safe if the behaviour happens anyway, and the last part covers recovery and recording.

You can write down what you know, and it is valuable: what a good day looks like, the early signs, and what helps. NICE recommends that a plan is based on a functional assessment carried out by someone trained to do it, with the family fully involved. Ask the GP or the council for a referral to the community learning disability team, and take your notes with you.

No. Challenging behaviour is not a diagnosis. It describes behaviour that puts the person or others at risk or affects their quality of life. A learning disability is lifelong and affects the way a person learns new things, and it is different from a learning difficulty such as dyslexia, which Mencap explains does not affect intellect. Mencap explains what a learning disability is.

Ask what behaviour the medicine is meant to help, how that is being measured, what side effects to watch for, and when it will be reviewed and when it might be reduced. NICE says a positive response should be reviewed after three months and then at least every six months. Do not stop it yourself, because reducing a medicine is done slowly with the prescriber.

No. We do not write, hold, review or check behaviour support plans, and there is no way to search for carers by PBS training. The plan comes from the professionals working with your son or daughter and your family. A support worker you choose can follow it, and you can share it with them at interview and ask how they would use it.

If anyone is in immediate danger, ringing 999 is the right thing to do. Afterwards, tell the named worker or the learning disability team what happened and ask for the plan to be reviewed. A hospital passport is a useful summary to hand to anyone who arrives.
