What does a child psychologist do?
A child psychologist's first meeting with a child is often indirect, through parents who are worried about how things are going at home, in day care, at school or with friends. The child psychologist helps the family understand what is happening and offers concrete ways forward. Sometimes that is professional parent counselling, where parents are equipped to support their child's well-being and development day to day. Much of a child psychologist's work is therefore a close collaboration with the parents, who play the decisive role in the child's everyday life.
Early support can make a marked difference in a child's life. With specialised knowledge and targeted tools, a child psychologist can help identify, understand and address difficulties ranging from emotional problems to learning challenges. This article walks through what a child psychologist actually does, which difficulties they can help with, and why the collaboration between parents and psychologist is essential for treatment to work.
The child psychologist's core competencies
A child psychologist is an expert in children's development and the many factors that shape their mental and emotional well-being. The work requires specialised knowledge of child development, specific therapeutic methods, and the ability to assess and diagnose. We go through these competencies below.
Specialised knowledge of child development
Child psychologists in Denmark hold a university degree in psychology and are licensed, since January 2026 automatically upon graduation. Experienced child psychologists have additionally completed the two-year clinical foundation training (klinisk basisuddannelse, before 2026 the autorisation) with supervised practice. Their expertise covers both the normal course of child development (relational, emotional and cognitive) and the kinds of deviations that can appear at different ages. This foundation matters for assessment, treatment and counselling alike: it is what makes it possible to spot early signs that a child is struggling, and to judge when a reaction is a normal part of growing up and when it calls for support.
Therapeutic methods and tools
Child psychologists use a range of methods, chosen to fit the child's age, maturity and difficulties. The goal is always a safe, supportive space where the child can express itself, process feelings and build strategies. The most common approaches are:
- Cognitive behavioural therapy (CBT): an evidence-based method that helps children identify and change unhelpful thought patterns and behaviour.
- Play therapy: often used with younger children who find it hard to put feelings into words. Through play, children communicate experiences and emotions; talk therapy and play-based approaches are frequently combined.
- Observation: watching the child in its natural environments (how it behaves, interacts and reacts) gives the psychologist deep insight into the child's development and needs.
- Family sessions: involving the family ensures a whole-picture approach. Understanding the dynamics at play makes it possible to find solutions that fit both the child and the family.
- Social skills training: for children who find it hard to make friends, read social cues or handle conflicts, structured training in understanding and navigating social situations can be particularly effective.
Assessment and diagnosis
Child psychologists are specialised in psychological assessment. After meeting the parents and gathering information from the adults around the child, such as teachers and day-care staff, the psychologist considers whether a formal assessment would help the child: whether a more precise description of the child's functioning would improve the support it receives.
In essence, an assessment clarifies whether the child can be met with the same expectations and supported with the same tools as its peers, or whether it needs something different. That understanding matters enormously, both for the child's well-being and for how the adults around the child interpret its behaviour. An assessment typically looks at:
- Cognitive development: learning and comprehension, for example with the WISC test
- Emotional development: emotional regulation
- Social functioning: relational skills
- Behavioural patterns: adaptation and reactions
Standardised diagnostic systems, most often ICD and DSM, are used as tools to identify and classify mental, developmental and behavioural difficulties, but the approach is always holistic. Where relevant, the assessment includes close collaboration with schools, institutions and other health professionals.
Difficulties a child psychologist can help with
Children can struggle with a wide range of difficulties. Some are temporary reactions to life events; others are long-lasting and call for professional help. These are the typical areas where a child psychologist makes a particular difference:
Emotional and behavioural problems
Emotional and behavioural problems are among the most common signs that a child is struggling. Anxiety can show up as general worry, phobias, performance anxiety, separation anxiety or social anxiety, and can make school, friendships and everyday changes hard to manage. Depression similarly drains a child's ability to engage with its surroundings. Difficulties can express themselves as:
- Persistent tantrums and angry outbursts
- Marked mood swings
- Anxiety expressed as excessive worry, overthinking and bodily discomfort
- Aggressive or destructive behaviour
- Withdrawal from social situations
Some of this is a natural part of development, especially when it is short-lived or tied to a specific situation. A child psychologist therefore always assesses whether the problems are persistent and affect the child's daily life to a degree that calls for treatment.
Social difficulties
One of the most common social challenges is difficulty reading social signals: other people's feelings, intentions or body language. This is often pronounced in children with developmental conditions such as autism or ADHD. A child who cannot tell when a comment is meant as a joke may hear criticism and react with anger or withdrawal. Some children pull out of social situations entirely; others react outwardly in ways that get read as aggressive, because the social codes are hard to crack.
Many children also find it hard to express their needs and feelings in ways adults and peers can understand. A child who is exhausted or overwhelmed may show it as anger or avoidance, which only deepens the misunderstanding. Here the child psychologist helps identify what is underneath the behaviour and builds strategies that help the child navigate social situations.
Learning difficulties
Learning difficulties can show up as trouble understanding the material, sustaining concentration, following instructions or resisting distraction. They can lead to academic struggles, school refusal, and low self-worth, because the child feels "worse" than classmates who keep up more easily.
Early identification matters. Through standardised tests and observation, the child psychologist can pinpoint and diagnose learning difficulties, offer both practical support and emotional guidance, and work closely with parents and teachers so the child's potential gets room to unfold. The psychologist also follows up over time, adjusting the approach as the child develops.
Trauma and crises
Children can be hit by traumatic experiences and crises: accidents, bereavement, bullying or other overwhelming events. Typical reactions include:
- Sleep problems and nightmares
- Anxiety and stress symptoms
- Difficulty concentrating
- Physical symptoms such as headaches or stomach aches
- Changed everyday behaviour
The psychologist always assesses how severe and long-lasting the symptoms are: some reactions are natural and pass by themselves, while symptoms that persist beyond the first month after the event may call for professional help. In treatment, the child gets a safe space to express what happened, and methods such as trauma-focused CBT or play therapy help the child process the experience and build healthy coping strategies: breathing exercises, relaxation techniques and ways to meet the anxiety, fear, grief or anger that often follow. Because trauma affects the whole family, the psychologist also works with parents and relatives: understanding the child's reactions, communicating supportively and keeping home a stable base.
Why the parent collaboration is decisive
Collaboration with parents is the foundation of successful treatment. Nobody knows the child better than its parents, and that knowledge is invaluable: parents contribute observations and insights from daily life that the psychologist cannot get anywhere else. A good child psychologist balances being the expert on children's development with recognising the parents' unique knowledge of exactly their child.
Parents often ask for concrete tools, and there is much they can do:
- Actively support the therapeutic work at home
- Implement helpful strategies and structured daily routines
- Use communication tools such as active listening and conflict-resolution techniques
- Take part in parent sessions
- Share observations and concerns openly
When parents feel confident and competent in their role, the child usually feels it too. Even small changes in the parents' approach can create significant positive change in a child's well-being.
