Evidence of a taxon underlying serious antisocial behavior in boys

It has recently been argued from studies of adults that chronically antisocial offenders constitute a discrete class of individuals. If this is true, it is likely that the class can be identified in childhood. Taxometric analyses were applied to items assessing antisociality in children. These items were similar in content to several established measures of antisocial behavior in children: the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Conduct Disorder; the Psychopathy Checklist-Youth Version; and the Childhood and Adolescent Taxon Scale. Participants were 1,111 school-age boys from a community sample of students. Taxometric analyses using each of the three measures of antisocial behavior yielded evidence of an underlying taxon. In addition, two other tests of consistency strengthened the conclusion that a taxon underlying serious antisocial behavior can be demonstrated in children.
