Obsessive Compulsive Disorder in Children
Obsessive-compulsive disorder (OCD) involves unwanted, recurring thoughts, images or urges called obsessions, and repetitive behaviours or mental acts called compulsions. A child may use a compulsion to reduce distress or prevent something feared from happening. The relief is usually temporary, which can strengthen the OCD cycle.
Occasional worries, routines and repeated behaviours are common in childhood. OCD is different because the symptoms are difficult to control, cause significant distress, take considerable time or interfere with everyday life, including school, sleep, friendships and family routines.
What OCD can look like
Obsessions may focus on contamination, illness, harm, mistakes, symmetry, religion, morality or sexual themes. Compulsions can be visible, such as washing, checking, arranging or repeating an action. They can also happen silently, such as counting, reviewing memories, repeating words, praying or trying to replace a distressing thought. Avoidance and repeated reassurance-seeking can also become part of the cycle.
For example, a child might have an intrusive fear that the house will burn down, feel intense anxiety, and repeatedly check an appliance. Checking briefly reduces the anxiety, but it also teaches the child that checking was necessary. This makes the urge more likely to return.
Intrusive thoughts about harm, sex or religion can feel frightening or shameful. In OCD, these thoughts are unwanted and do not automatically mean that a child wants to act on them. A qualified clinician should still assess any genuine safety concern, including intent, plans or other warning signs.
Is OCD an anxiety disorder?
Anxiety is central to many experiences of OCD, and some Australian consumer health information describes it as an anxiety disorder. In the DSM-5-TR diagnostic framework, however, OCD is grouped separately under Obsessive-Compulsive and Related Disorders. The practical point for families is that OCD has a recognisable cycle and requires treatment designed specifically for that cycle.

Signs of OCD in children
Children do not always recognise that their thoughts or rituals are excessive. Some hide symptoms because they feel embarrassed, fear being judged or worry that speaking about a thought will make it come true. Signs vary, and no single behaviour confirms OCD. Possible signs include:
- lengthy washing, checking, arranging, counting or repeating routines
- frequent requests for reassurance or repeated questions that never feel settled
- avoiding people, objects, places, schoolwork or activities that trigger distress
- becoming unusually slow when dressing, writing, packing or completing everyday tasks
- distress when a ritual is interrupted or something does not feel “just right”
- sleep disruption, irritability, shame or withdrawal
- declining school participation or performance
- family routines increasingly organised around the child’s fears or rituals
These experiences can also occur for other reasons. Assessment should consider the child’s development, the pattern and purpose of the behaviour, its effect on daily functioning, co-occurring conditions and any physical or safety concerns. OCD may be considered when obsessions or compulsions are time-consuming, often more than one hour a day, or cause significant distress or impairment. The one-hour mark is an example, not an absolute requirement when the impact is already substantial.
Evidence-based treatment for childhood OCD
The best-supported psychological treatment is cognitive behavioural therapy (CBT) that includes exposure and response prevention (ERP). Child-adapted ERP is collaborative and gradual. With a suitably trained clinician, the child learns about the OCD cycle, creates a step-by-step plan and practises facing manageable triggers while reducing the ritual or reassurance response. The aim is not to force a child into their greatest fear. It is to build confidence through challenges that are planned, developmentally appropriate and achievable.
Parents and caregivers are commonly involved so they can support practice, reinforce progress and respond consistently at home. Recent evidence indicates that ERP, delivered in person or by telehealth, can reduce paediatric OCD symptoms. Medication, commonly a selective serotonin reuptake inhibitor, may also be considered by a medical practitioner or child and adolescent psychiatrist, particularly when symptoms are more severe or therapy alone has not been sufficient. Decisions about medication require individual assessment and monitoring.
If OCD is suspected, speak with a GP, psychologist or child and adolescent psychiatrist. Look for a clinician with experience in childhood OCD and CBT with ERP, rather than assuming that general supportive counselling alone will target the OCD cycle.

How families can help
OCD affects the whole family. In an understandable effort to reduce a child’s distress, family members may provide repeated reassurance, help complete rituals, change plans or remove triggers. This is called family accommodation. It can bring short-term relief but may unintentionally keep the OCD cycle going.
Reducing accommodation should be planned and gradual, ideally with the treating clinician. Abruptly refusing every ritual or reassurance request can increase distress and conflict. Families can agree on one small change at a time, use calm and consistent language, and praise effort rather than demanding that anxiety disappear.
According to Dr Kimberley O’Brien, parents can help by acknowledging the child’s distress without debating the intrusive thought or repeatedly reassuring them, then returning to the child’s agreed treatment plan.
Some children find it useful to give OCD a neutral or playful name so they can separate themselves from the symptoms. This should be optional and led by the child. Avoid labels that feel shaming or make the child feel responsible for having OCD.
Maintain ordinary family routines where possible, avoid punishment or blame, and make space for rest and enjoyable activities. Parents and caregivers may also need support for their own stress, particularly when OCD has been shaping family life for some time.

Practical next steps for parents
- Notice the pattern. Record triggers, obsessions, rituals, reassurance requests, avoidance and the effect on daily life without interrogating the child.
- Start a calm conversation. Let your child know that unwanted thoughts are not their fault and that they can talk without being judged.
- Seek an assessment. Ask whether the clinician has specific experience treating childhood OCD with CBT and ERP.
- Agree on a family response. Work with the clinician to reduce accommodation gradually and consistently.
- Support practice. Celebrate brave attempts and persistence, not perfect performance.
Early support can reduce the disruption OCD causes and help a child regain confidence in everyday activities. Treatment should be tailored to the child’s age, symptoms, strengths and family circumstances.
