OCD in children and teenagers
Childhood OCD is treatable, and it responds to a specific therapy done properly. If reassurance, rituals and 'just one more time' have taken over your family's evenings, this page explains what is happening and what actually changes it.
What OCD looks like in a child
Adults with OCD usually know their fear is out of proportion. Children often do not, and younger children may not be able to describe the thought at all — only the feeling that something is wrong and must be put right. So what you see is rarely “obsessions and compulsions”. What you see is behaviour.
- Questions that need answering again, in exactly the same words, however many times you have already answered them.
- Bedtimes or morning routines that have grown extra steps, and that collapse into distress if a step is skipped or done in the wrong order.
- Long stretches in the bathroom, or handwashing that has moved past hygiene into raw skin.
- Homework redone, rubbed out and redone, or handed in late because it was never quite right.
- Avoidance that looks like fussiness — certain rooms, certain clothes, certain words, certain numbers.
- Confessing: telling you about a thought they had, and needing you to say it does not make them a bad person.
- Sudden anger, which is usually what fear looks like when a ritual has been interrupted.
Intrusive thoughts in children commonly involve harm coming to a parent, contamination and illness, symmetry and “just right” feelings, and — particularly in teenagers — violent, sexual or blasphemous thoughts that horrify them precisely because they are so at odds with who they are. Teenagers frequently hide these for years. The content of the thought is almost never the point. The relationship with the thought is.
The thing most families get wrong, entirely reasonably
When your child is frightened, you reassure them. When the reassurance works, you do it again. Over months this becomes an arrangement: your child outsources the anxiety to you, and you carry it. Clinicians call this family accommodation, and it is present in the large majority of childhood OCD cases.
It is not a parenting failure. It is what any loving parent does when their child is distressed, and in the short term it works, which is exactly why it is so hard to stop. But every time the ritual is completed, OCD is told it was right to demand it. Reducing accommodation — carefully, gradually, and with the child on board wherever possible — is one of the most powerful levers in the whole of childhood OCD treatment.
What the treatment actually is
The treatment with the strongest evidence base for childhood OCD is Exposure and Response Prevention, a specific form of CBT. NICE recommends CBT including ERP as the first-line psychological treatment for OCD in children and young people. It is not a general talking therapy, and it is not about persuading your child their fear is irrational — they usually already know.
In practice it works like this. We build a shared map of the OCD, including which situations set it off and what your child does to make the feeling stop. Then we work up a ladder of situations, from manageable to hard, and your child practises facing them without performing the ritual. The anxiety rises, and then — without the compulsion, and this is the part that surprises everybody — it comes down anyway. Repeated often enough, the brain learns something the reassurance was preventing it from learning: that the feared thing does not happen, and that the feeling passes on its own.
With a nine-year-old this looks like games, competitions, sticker charts and a lot of externalising the OCD as a bully to be beaten rather than a part of themselves. With a sixteen-year-old it looks much more like adult treatment, with the young person setting their own targets and parents deliberately stepping back. Either way, the sessions are active, we agree the steps together, and nothing is sprung on your child.
Parents are part of the treatment, not observers of it
In child OCD work, most of the change happens between sessions, at home, in the moments where the ritual usually happens. So a substantial part of what I do is coaching parents: what to say when the question comes for the fourth time, how to reduce accommodation without provoking a war, and how to hold a boundary calmly when your child is genuinely distressed. Parents often tell me this is the part that changed things.
If your child refuses to come
This is common, and it is not the end of the road. SPACE is a parent-based treatment developed at Yale in which the parents attend and the child does not need to. It works by systematically changing parental responses and accommodation rather than by treating the child directly, and trials have found it as comparable to child-delivered CBT for childhood anxiety. If your teenager has flatly refused therapy, this is very often where we start.
When it is not straightforward
Childhood OCD frequently arrives with company. Around a third of children with OCD also meet criteria for a tic disorder, many have co-occurring anxiety disorders, and co-occurring ADHD is common enough that it should be actively considered rather than stumbled upon — it changes how ERP needs to be delivered. Autistic children can absolutely have OCD, but distinguishing a compulsion driven by fear from a routine that is regulating and valued matters enormously for treatment, and getting that distinction wrong causes real harm.
Where a child has stopped attending school, stopped eating certain foods, or where the onset was abrupt rather than gradual, the assessment needs to be wider. That is what the first appointment is for.
Working with me
I am a clinical psychologist who has spent most of my career doing this specific work. I trained at the University of Washington and completed a postdoctoral fellowship in child and adolescent anxiety at the Evidence-Based Treatment Centers of Seattle, where I went on to be Assistant Director of the Child Anxiety Center. I am board certified in Behavioral and Cognitive Psychology by the American Board of Professional Psychology, registered with the HCPC, and chartered with the British Psychological Society.
I see children and teenagers online across the UK and in person near Nottingham and Mansfield. Appointments run into the evening so sessions do not have to cost your child a school day. The first step is a free 30-minute call: you tell me what has been happening, and I will tell you honestly whether I think I can help.
Common questions
How do I know if it is OCD and not just a phase?
Most children go through periods of superstition, ritual or rigidity, and most of it passes. The features that point towards OCD are distress, time and interference: the child is genuinely upset by the thoughts rather than enjoying the ritual, the routines take up increasing amounts of time, and family life is bending around them. If mornings, bedtimes or bathrooms have started to run on your child’s rules rather than yours, that is worth assessing.
My child will not talk about it. Can anything be done?
Yes. Parent-based treatment is well evidenced for exactly this situation. In SPACE (Supportive Parenting for Anxious Childhood Emotions), the parents attend and the child does not have to. We work on how you respond to the anxiety rather than on persuading your child to engage, and children’s symptoms improve as a result. It is a genuine treatment route, not a consolation prize.
How long does treatment usually take?
For childhood OCD without significant complications, a typical course is around 12 to 16 sessions after the assessment, with progress usually visible well before the end. More complex presentations, or ones with a long history and heavy family accommodation, can take longer. I will give you an honest estimate after the assessment rather than an open-ended commitment.
Does my child need medication?
NICE recommends starting with psychological therapy for mild to moderate OCD in children and young people, with medication considered alongside therapy for more severe presentations or where therapy alone has not been enough. I am a psychologist and do not prescribe, but I work alongside GPs and psychiatrists where medication is being considered, and I will say plainly if I think it should be on the table.
What is PANDAS or PANS, and should I be worried about it?
PANS and PANDAS describe a sudden, dramatic onset of OCD symptoms in a child, sometimes following an infection, often with other changes such as tics, restricted eating, handwriting deterioration or severe separation anxiety appearing at the same time. It is uncommon and it remains a contested area, but abrupt onset over days rather than months is worth raising with your GP. Where it is suspected, psychological treatment still helps and runs alongside any medical investigation rather than instead of it.
Can you work with my child’s school?
Yes, with your consent. Schools are frequently where compulsions are most visible and most accommodated — extra time in the toilet, repeated reassurance from a teaching assistant, permission to redo work. A short conversation with the right person at school often makes a substantial difference, and I can provide a summary letter setting out what will and will not help.
