Children who show defiant, hostile and negative behaviour towards adults and other children over a long period may have oppositional defiant disorder. Help is available.

What is oppositional defiant disorder?

Oppositional Defiant Disorder (ODD) is a behavioural disorder usually diagnosed in childhood. Children with ODD exhibit a pattern of defiant, hostile and negative behaviour towards adults and other children over an extended period of time. This behaviour is different from children’s normal behaviours of testing limits and is more intense and frequent.

What are the symptoms of ODD?

The symptoms of oppositional defiant disorder can vary from child to child but often include a pattern of negative, defiant and hostile behaviour. Here are some common symptoms:

  • Frequent outbursts: The child often has intense outbursts of anger and frustration.
  • Arguing with adults: The child often questions rules or instructions and is prone to arguing.
  • Deliberately upsetting behaviour: The child may seem to deliberately try to annoy or upset others.
  • Defying rules and instructions: The child refuses to follow rules or ignores adult requests and instructions.
  • Blaming others: The child may blame others for their mistakes or bad behaviour.
  • Easily irritated: The child is easily irritated or upset by others.
  • Frequently angry or resentful: The child seems to be angry or resentful much of the time.
  • Revengeful: The child may be vindictive or preoccupied with thoughts of revenge.

These symptoms must be present for at least six months for a diagnosis to be made. It is important to note that all children may exhibit some of these behaviours at different times, but for children with ODD, these behaviours are more intense and frequent, significantly affecting their daily functioning and social relationships.

What set our therapist apart was her genuine empathy and personal insight. Not only did she possess a deep understanding of neurodiversity, but she also shared personal experiences that resonated with us, creating an instant connection and fostering a sense of trust!

Oppositional defiant disorder at different ages

ODD affects children and adolescents differently depending on their age. In young children, ODD can manifest itself as intense anger and resistance to routines. As children reach preschool age, the symptoms become more pronounced, with direct challenges to rules and difficulties in social settings. In school age children, these behaviours can lead to academic and social problems, while adolescence can introduce increased risky behaviour and conflicts with authority figures. Early intervention with strategies such as parent education and behavioural therapy is essential for management, with the goal of supporting the child’s development and promoting positive social interactions. Collaboration between family, school and professionals is central to effectively supporting children with oppositional defiant disorder.

Oppositional defiant disorder and neuropsychiatric conditions

ODD can often co-exist with other neuropsychiatric conditions such as ADHD and Autism Spectrum Disorder (ASD). These diagnoses can amplify each other’s symptoms and make treatment more complex. For example, the impulsivity of ADHD may be intensified by defiant behaviours, while communication difficulties in ASD may express themselves as defiant behaviours.

Integrated treatment plans that combine behavioural therapy, medical treatment and personalized support are essential to manage these complex cases. To provide effective treatment and support for children with ODD and co-occurring neuropsychiatric conditions, parent education and family therapy play a central role.

Treatment of oppositional defiant disorder

Treatment for ODD focuses on improving the child’s social skills, emotional regulation, and reducing challenging behaviours using a combination of treatment methods. Behavioural therapy and parenting support play a central role, with parents learning effective strategies to manage behavioural problems at home. Cognitive behavioural therapy (CBT) is used to help the child identify and change negative thought patterns. Additionally, social skills training focuses on developing effective ways to interact with others.

Family therapy is important for improving communication within the family and resolving conflicts, thus strengthening the parent-child relationship. School-based interventions, including adjustments to the school environment and individual support, help the child’s learning and social interaction. Although there is no specific medication for oppositional defiant disorder, medication can be considered to manage concurrent symptoms related to conditions such as ADHD.

A comprehensive treatment approach combining these methods is often recommended to address oppositional defiant disorder. It involves close collaboration between the family, school staff and health professionals to create an individualized treatment plan. Early intervention is important to reduce ODD symptoms and support the child’s development over time.

How does treatment with a child psychologist work?

Seeking help from a psychologist or therapist is an important step when a child is experiencing mental health difficulties or if you are having difficulties as a parent. Here is a brief overview of what treatment can look like:

1. Initial Assessment

An initial consultation involves the psychologist assessing needs through conversations with the child and parents.

2. Treatment plan

An individualized plan is developed based on the child’s specific situation and needs. Common approaches include play therapy for younger children, where play is used as a tool for expression and processing. Talk therapy and cognitive behavioural therapy (CBT) are often useful for older children. CBT focuses on changing negative thought patterns and behaviours. Other methods such as family therapy can also be helpful.

3. Parental counselling

Parents receive guidance and support to better help their child at home.

4. Monitoring and adjustment

The treatment plan is continuously evaluated and adjusted as needed to ensure the best possible outcome.

A first step in seeking help

It is important to remember that each child is unique, and therefore treatment may vary. Working together with a child psychologist can give you and your child the tools needed to manage emotions and behaviours in a healthy way. At Lavendla, we have psychologists and therapists who can help make the difficult easier.
