OCD in Children and Young People: Recognising Symptoms, Assessment Steps and Evidence-Based Treatment

Obsessive-compulsive disorder (OCD) is a recognised mental health condition that can affect children and young people. It involves unwanted, intrusive thoughts, images or urges, known as obsessions, and repetitive behaviours or mental acts, known as compulsions. These experiences can be distressing, time-consuming and disruptive to everyday life, even when a young person understands that their fears or rituals may not seem logical.

OCD is more than being tidy, cautious or particular. Many children have routines or preferences, but OCD is usually associated with significant anxiety, distress or interference with family life, school, friendships, sleep or activities. With an appropriate assessment and evidence-based treatment, many young people make meaningful improvements.

What can OCD look like in children and young people?

OCD symptoms can vary considerably. Some children may talk about their worries, while others hide them because they feel embarrassed, frightened or concerned that something bad will happen if they disclose them.

Common obsessions

Obsessions are recurrent and unwanted thoughts, images or urges. They may involve:

Fear of germs, contamination, illness or chemicals
Worries about causing harm to themselves or someone else
Fears that a parent or family member will become ill or have an accident
Concerns about making a mistake, behaving badly or being responsible for a harmful event
A need for things to feel “just right”, symmetrical or exact
Distressing intrusive thoughts involving religion, sex, aggression or identity
Repeated doubts, such as whether a door is locked or an assignment is correct

Intrusive thoughts do not mean that a child wants to act on them or that they are likely to do so. A key feature of OCD is often the distress caused by the thought and the efforts made to neutralise, prevent or obtain certainty about it.

Common compulsions

Compulsions are repetitive behaviours or mental acts carried out in response to an obsession or a feeling that something is not right. They may include:

Excessive handwashing, showering, cleaning or changing clothes
Checking locks, appliances, homework, messages or bodily sensations
Repeating words, movements, prayers or actions
Counting, arranging or touching objects in a particular way
Seeking repeated reassurance from parents, teachers or friends
Avoiding places, objects, people or activities associated with feared consequences
Repeating thoughts mentally, reviewing memories or trying to suppress an unwanted thought

Compulsions may be less visible than washing or checking. Reassurance-seeking, avoidance and mental rituals can be particularly difficult to recognise. Parents may also find themselves changing routines, answering the same questions repeatedly or carrying out tasks for their child. This is sometimes called family accommodation. It is understandable, but it can unintentionally maintain the OCD cycle.

When should a child be assessed for OCD?

Professional assessment is appropriate when symptoms are persistent, cause distress or interfere with daily functioning. Possible signs include taking a long time to get ready, struggling to leave the house, repeatedly returning to check something, avoiding school or activities, needing extensive reassurance, or becoming highly distressed when a ritual is interrupted.

OCD may occur alongside anxiety disorders, depression, tics, autism, ADHD or other difficulties. Symptoms can also be confused with developmentally typical routines, generalised anxiety, health anxiety, eating difficulties, trauma-related symptoms or a psychotic illness. A careful assessment is therefore important, particularly where the content of intrusive thoughts is frightening or unusual.

What happens during an OCD assessment?

At Healing Young Minds LTD, assessment is undertaken by clinicians experienced in child and adolescent mental health. The aim is to understand the young person’s experiences in context rather than focusing only on a checklist of symptoms.

Understanding the difficulties

The clinician will explore the nature, frequency and intensity of obsessions and compulsions. This includes looking at triggers, what the young person fears might happen, what they do to feel safer, and how long rituals or avoidance take. The assessment considers the impact on school attendance, learning, friendships, sleep, family relationships and self-care.

Hearing from the young person and family

Young people are given opportunities to speak privately as well as with their parents or carers, when appropriate. Parents can provide valuable information about changes in behaviour, routines, reassurance-seeking and family accommodation. For younger children, observation and developmentally appropriate discussion may be particularly helpful.

Considering the wider clinical picture

The clinician will ask about mood, anxiety, tics, neurodevelopmental differences, eating, sleep, physical health and any experiences of self-harm or suicidal thoughts. Safeguarding and risk are considered sensitively. The assessment also reviews previous support, treatments, medication and factors that may be maintaining the difficulties.

Where appropriate, information from school or other professionals may help build a fuller picture. The outcome should include a clear formulation, explanation of the symptoms, and recommendations for treatment. Assessment follows recognised clinical principles, including the approach outlined in the National Institute for Health and Care Excellence (NICE) guideline CG31: Obsessive-compulsive disorder and body dysmorphic disorder.

Evidence-based treatment for OCD

Cognitive behavioural therapy with exposure and response prevention

The main psychological treatment for OCD is cognitive behavioural therapy (CBT) that includes exposure and response prevention, often abbreviated to ERP. This involves helping a young person gradually and safely face feared situations, thoughts or sensations while reducing the compulsions and reassurance-seeking that usually follow.

ERP is planned collaboratively and proceeds at a suitable pace. It is not about forcing a child into overwhelming situations or asking them to accept a feared outcome as certain. Instead, the young person learns that anxiety can change over time and that they can respond differently to intrusive thoughts without performing rituals.

CBT for children and young people commonly involves parents or carers. Families may learn how to respond consistently to reassurance-seeking, support agreed practice between sessions and reduce accommodation without withdrawing warmth or reassurance about the child’s emotional wellbeing.

Medication

Medication may be considered when OCD is moderate to severe, when symptoms significantly limit participation in psychological treatment, or when an adequate course of CBT has not led to sufficient improvement. Selective serotonin reuptake inhibitors (SSRIs) may be prescribed by an appropriately experienced clinician, alongside careful discussion of potential benefits, side effects and monitoring.

Medication decisions depend on the young person’s age, clinical presentation, other conditions and previous treatment. Children and young people taking an SSRI require appropriate follow-up, including monitoring of mood, agitation, sleep and any thoughts of self-harm. Medication should not be started, stopped or changed without medical advice.

Combined treatment and ongoing review

Some young people benefit from psychological treatment and medication together. Treatment should be reviewed regularly, with progress assessed against the goals agreed with the child or young person and their family. Adjustments may be needed if symptoms change, new difficulties emerge or treatment is not sufficiently effective.

How families can support a young person

Listen calmly and take the distress seriously without repeatedly debating the obsession.
Remember that intrusive thoughts are symptoms, not intentions or character traits.
Notice reassurance-seeking and rituals, and discuss changes with the treating clinician.
Support agreed CBT or ERP practice rather than creating unplanned challenges.
Keep routines as predictable as possible, while avoiding arrangements that allow OCD to control family life.
Speak with the school about practical support where symptoms affect attendance, concentration or transitions.

If a young person is at immediate risk of harming themselves or someone else, seek urgent help through emergency services or local crisis services. OCD can be extremely distressing, but it is treatable and early support can help prevent symptoms becoming more established.
