Relationship between Psychiatric Illness and Conduct Disorder in Adolescents

Abstract

Ninety-six psychiatrically ill adolescents admitted to an adolescent inpatient service were systematically assessed to determine the morbidity of conduct disorder (CD), with other Axis I psychiatric disorders. Twenty-six (27%) met DSM-111 criteria for CD in addition to other Axis I disorders. A CD diagnosis was significantly associated with substance abuse, and attention deficit disorder with hyperactivity. Although CD was found in 21 % of depressives it was more commonly found inpatients with psychotic disorders (25 %) and bipolar (42 %) disorders. These findings suggest that CD may be commonly found in a variety of adolescent psychiatric disorders. The implications of this finding for pharmacologic treatment of CD, the clinical assessment of the CD patient, and possible relationships between CD and adolescent psychiatric disorders are discussed.
