Generalised Anxiety Disorder in Children: Signs and Support

Signs of generalised anxiety in children

Generalised anxiety can affect thoughts, feelings, the body and behaviour. A child might:

• worry repeatedly about schoolwork, health, safety, money, family members, friendships or world events
• ask the same “what if?” question or seek reassurance many times
• expect mistakes or ordinary uncertainty to lead to serious consequences
• aim for perfection, over-prepare or spend much longer than needed on tasks
• avoid trying, delay starting or refuse activities because the outcome is uncertain
• have difficulty concentrating because attention is occupied by worry
• become irritable, tearful, restless or unusually quiet
• report headaches, stomach aches, tiredness, muscle tension or feeling unwell
• take a long time to settle to sleep or wake with worries
• need detailed plans and find unexpected change particularly difficult.

These signs are not unique to GAD. Focus on the pattern across time and settings rather than interpreting one behaviour as proof.

Generalised anxiety and other concerns

GAD centres on difficult-to-control worry across many topics. This differs from anxiety focused mainly on social judgement, separation from caregivers, a specific object or situation, panic sensations or intrusive thoughts and rituals. Children can experience more than one anxiety disorder at the same time.

What should an assessment consider?

A careful assessment usually gathers the child’s perspective, developmental and health history, family observations and information from school or other relevant settings. It explores the content and frequency of worries, associated symptoms, avoidance, reassurance seeking, strengths, safety and functional impact.

Professionals may also consider:

• other anxiety disorders, obsessive-compulsive disorder, depression and trauma responses
• autism, ADHD, learning differences and communication needs
• sleep problems, pain, illness, medication effects or other medical explanations
• bullying, discrimination, family stress, grief, relocation or major change
• cultural expectations, family beliefs and whether the child is communicating in an additional language.

Several conditions can look similar or occur together. The goal is to understand what is maintaining the difficulty and what support fits the child, not simply to attach a label.

How parents can help with persistent worry

Listen and name the pattern

Begin with curiosity. Ask what the child thinks might happen, how likely it feels, what they notice in their body and what they do next. Validate the feeling without confirming that the feared outcome is inevitable. For example: “I can see this feels uncertain. Let’s work out what you know and what you can do if it is difficult.”

Respond to repeated reassurance carefully

Repeated reassurance can calm anxiety briefly while teaching the child that certainty must come from another person. Agree on a supportive response, then help the child use their own plan. Change this gradually. Abruptly refusing all reassurance can increase distress and damage trust.

Build tolerance for uncertainty

Use small everyday opportunities to practise not knowing exactly what will happen. Let the child make a manageable choice, attempt a task without repeated checking or wait briefly before asking again. Praise effort, flexibility and recovery rather than a perfect result.

Use gradual, meaningful steps

Avoidance can keep anxiety powerful because the child does not get the chance to learn that they can cope. Break an important goal into manageable steps and practise consistently. The aim is supported participation, not forcing a child into the most difficult situation or removing all help at once.

Protect routines without making them rigid

Regular sleep, movement, meals, connection and predictable preparation can support wellbeing. Relaxation or slow breathing may help a child settle, but these strategies should not become rules the child believes they must complete perfectly before facing uncertainty.

Support at school

Parents, the child and school can identify where worry interferes with learning or participation. Helpful supports might include:

• one trusted staff member for a brief, planned check-in
• clear task instructions and a defined starting point
• advance notice of genuine changes when possible
• breaking large assignments into reviewed stages
• a gradual plan for presentations, camps, tests or unfamiliar activities
• limits on repeated checking that are introduced compassionately
• a way for the child to request help without public attention.

Adjustments should address an identified barrier and be reviewed. They should support access while helping the child build skills, rather than permanently removing every uncertain or challenging situation.

What treatments have evidence?

Cognitive behavioural therapy (CBT) is a recommended treatment for anxiety disorders in children and adolescents. It commonly helps children understand the anxiety cycle, examine anxious predictions, reduce avoidance and practise approaching feared or uncertain situations gradually.

A 2020 Cochrane review included 87 randomised studies with 5,964 participants. It found moderate- to low-certainty evidence that CBT was more effective than a waiting list or no treatment for childhood anxiety disorders. Evidence was less clear when CBT was compared with other active treatments, and longer-term evidence was limited. The findings apply across childhood anxiety disorders and should not be read as a guaranteed result for every child with GAD.

The 2020 American Academy of Child and Adolescent Psychiatry guideline found empirical support for CBT and certain antidepressant medicines for anxiety disorders in people aged 6 to 18 years. Medication decisions require assessment and monitoring by an authorised medical practitioner and should consider age, severity, co-occurring conditions, preferences, potential benefits and adverse effects.

Parent involvement can be useful, particularly when accommodation and reassurance are maintaining anxiety. A 2022 systematic review found that parent-only interventions may reduce child anxiety compared with waiting-list controls, but many included studies were methodologically weak and there was no clear evidence that one parent-only format was superior. Treatment should be selected and reviewed for the individual child.

When to seek professional help

Consider speaking with a GP, paediatrician or psychologist when worry:

• has persisted for months or is becoming more restrictive
• interferes with sleep, school, friendships, family life or usual activities
• causes frequent physical distress or repeated absences
• leads to extensive reassurance seeking, checking, avoidance or perfectionism
• occurs alongside low mood, self-harm thoughts, eating changes, substance use or another significant concern.

Families do not need to wait until every diagnostic criterion is met before asking for help. Early support can clarify what is happening and identify a proportionate next step.

Quirky Kid can help families explore an appropriate pathway through a child psychology consultation or an initial appointment. Current clinician availability, service scope, fees and rebates should be confirmed directly.

If a child is in immediate danger of harming themselves or someone else, call Triple Zero (000). Children and young people can contact Kids Helpline on 1800 55 1800. Lifeline is available on 13 11 14.

Key points for parents

• GAD involves persistent, difficult-to-control worry across several areas of life.
• Look at distress and functional impact, not one symptom or questionnaire score.
• Validate the child while reducing avoidance and reassurance gradually.
• Consider developmental, medical, learning, cultural and environmental factors.
• CBT has evidence for childhood anxiety, but support should be individualised and reviewed.
