De-escalation and Low-Arousal Approaches

Practice guides · Published 16 August 2026 · Last updated 16 August 2026

Every service that supports people who sometimes become distressed, whether a children's home under Ofsted or an adult service under CQC, has a legal and moral duty to prevent crisis where possible and to respond to it in the least restrictive way. Restraint is lawful only when necessary and proportionate, and in children's homes it is tightly limited by Regulation 20 of the Children's Homes (England) Regulations 2015. The Restraint Reduction Network standards, widely adopted across health and social care, make the direction of travel clear: services are expected to reduce restrictive practices year on year. The practical route to that is de-escalation, and behind good de-escalation sits the low-arousal approach.

What low arousal means

The low-arousal approach, developed by clinical psychologist Andrew McDonnell and colleagues, starts from a blunt observation: in a crisis, the person is already carrying more stress than they can manage, and most of what staff instinctively do adds stress rather than removes it. Demands, questions, crowding, eye contact, touch, raised voices and audiences all increase arousal. The low-arousal response is to strip demands and stimulation right down until the person can regulate again. You are not trying to win the moment; you are trying to lower the temperature.

A second principle matters just as much: your own arousal is contagious. If you are tense, loud and fast, you feed the crisis. If you are slow, quiet and genuinely calm, you offer the person a nervous system to borrow. Managing yourself is the first technique.

Before the crisis: know the signs and the plan

Most incidents have a build-up. Learn each person's individual signs of rising distress, such as pacing, going quiet, a particular phrase, seeking or avoiding people, and the triggers that commonly precede them, such as transitions, contact visits, noise, hunger or perceived unfairness. Every person who may become distressed should have an individual behaviour support or safety plan describing what helps and what makes things worse. Read it before you need it. Acting early, with a snack, a walk, a change of face or simply naming what you see, is the most effective de-escalation there is.

During: body language and position

• Distance. Give more personal space than usual, at least a couple of arm's lengths. Crowding is a threat signal.
• Angle. Stand at a slight angle rather than square-on, which reads as confrontation. Keep your hands visible, open and low.
• Height. If it is safe, lower yourself: sit, lean, drop your shoulders. Towering over someone escalates.
• Eyes. Soften eye contact; do not stare someone down, and do not demand they look at you.
• Movement. Move slowly and predictably. Say what you are going to do before you do it.
• Voice. Slower, lower, quieter. Short sentences. Long pauses. Silence is a tool, not a failure.

During: what to say and what to avoid

Say less than you think you need to. A distressed brain processes little language. Helpful lines are short, warm and low-demand: I'm here. You're not in trouble. Take your time. I can see this is really hard. Offer simple, genuine choices where you can, such as would you rather be in your room or the garden, because choice returns a sense of control.

Avoid the classics that escalate: calm down (nobody has ever calmed down on request), threats and ultimatums, sarcasm, why questions, arguing back over insults, listing consequences mid-crisis, and dragging up earlier incidents. Do not take the bait of personal abuse; it is arousal talking. If a rule or refusal must stand, state it once, briefly and without triumph, then move back to empathy.

During: the environment and the audience

Think of the room as part of the intervention. Reduce noise, turn off the television, dim harsh lighting if you can. Remove the audience, because peers watching raise the stakes for everyone; it is usually easier to move other people away than the distressed person. Clear obvious hazards quietly. Know your exits and never let yourself be trapped in a corner, and avoid trapping the other person, because a blocked escape route turns distress into panic.

Consider a change of face. If you are the trigger, or the relationship is inflamed, handing over to a colleague is skilled practice, not defeat. Agree quiet signals in the team for swapping in and out.

If de-escalation does not work

Sometimes, despite everything, there is immediate risk of serious harm. Any physical intervention must be necessary, proportionate, for the shortest possible time, and carried out only by staff trained in an accredited approach; in children's homes it must never be used as punishment, and Regulation 20 requires a written record and the opportunity for the child to add their view. Restraint is always a sign that prevention has run out, and every use should prompt the question: what could we change so this is not needed next time?

After: debrief, twice

The incident is not over when the shouting stops. Two debriefs matter.

With the person. Once they are genuinely calm, which may be hours later or the next day, reconnect gently. The goals are repair and learning, not blame: checking they are okay, hearing their account, acknowledging anything staff got wrong, and agreeing together what might help next time. For children, this supports the positive relationships standard; for adults, it is part of person-centred care under Regulation 9 of the 2014 regulated activities regulations.

With the team. A staff debrief covers facts, feelings and learning: what happened, what the early signs were, what worked, what escalated things, and what changes to the plan, the environment or the rota follow. Staff involved in frightening incidents need support too; unprocessed incidents fuel burnout and defensive practice. Update the person's support plan with anything learned, and make sure recording is factual and complete, including antecedents, staff responses and any physical intervention.

Dos and don'ts

Dos

• Learn each person's triggers, early warning signs and support plan before a crisis, and act early.
• Manage your own arousal first: breathe, slow down, drop your voice and shoulders.
• Give space, stand at an angle, keep hands open and movements slow and announced.
• Use few words, long pauses, empathy and simple genuine choices.
• Reduce noise, remove the audience and keep escape routes open for everyone.
• Swap staff when a change of face would lower the temperature.
• Debrief with the person and the team after every significant incident, and update the plan.

Don'ts

• Don't crowd, touch, stare down or stand square-on to a distressed person.
• Don't say calm down, issue ultimatums, argue with insults or list consequences mid-crisis.
• Don't pile in multiple staff all talking at once; one calm voice leads.
• Don't corner the person or let yourself be cornered.
• Don't use restraint unless there is immediate risk of serious harm, and never as punishment or for convenience.
• Don't skip the debrief or leave records vague; every incident is data for prevention.
