Oppositional defiant disorder (ODD) is a childhood behaviour problem characterised by an angry or irritable mood and constant disobedience and hostility. Around one in 10 children under the age of 12 years are thought to have ODD, with ODD occurring more frequently in boys.
Early intervention and treatment is important, as untreated ODD may continue, impacting on a child’s relationships with family, peers, teachers. When problem behaviours and defiance persists, it can result in significant impairment with relationships, career prospects and quality of life.
Some children with ODD will develop the more serious conduct disorder (CD), which is characterised by aggressive law-breaking and violent behaviours. Children may also have co-morbid problems. These can include ADHD, anxiety and mood problems.
