Conduct disorder is classified in the fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM).[10] It is diagnosed based on a prolonged pattern of antisocial behaviour such as serious violation of laws and social norms and rules in people younger than the age of 18. Similar criteria are used in those over the age of 18 for the diagnosis of antisocial personality disorder.[40] No proposed revisions for the main criteria of conduct disorder exist in the DSM-5; there is a recommendation by the work group to add an additional specifier for callous and unemotional traits.[41] According to DSM-5 criteria for conduct disorder, there are four categories that could be present in the child's behavior: aggression to people and animals, destruction of property, deceitfulness or theft, and serious violation of rules.[42]
