The conditions that contribute to the development of conduct disorder are considered to be multifactorial, with many factors (multifactorial) contributing to the cause. Neuropsychological testing has shown that children and adolescents with conduct disorders seem to have an impairment in the frontal lobe of the brain that interferes with their ability to plan, avoid harm, and learn from negative experiences. Childhood temperament is considered to have a genetic basis. Children or adolescents who are considered to have a difficult temperament are more likely to develop behavior problems. Children or adolescents from disadvantaged, dysfunctional, and disorganized home environments are more likely to develop conduct disorders. Social problems and peer group rejection have been found to contribute to delinquency. Low socioeconomic status has been associated with conduct disorders. Children and adolescents exhibiting delinquent and aggressive behaviors have distinctive cognitive and psychological profiles when compared to children with other Mental Health Disorders problems and control groups. All of the possible contributing factors influence how children and adolescents interact with other people.
