AbstractAggressiveness and explosiveness characterize a subgroup of children diagnosed with conduct disorder (CD). Few double-blind, placebo-controlled studies have been conducted in aggressive children with CD, and no study has differentiated placebo responders from nonresponders. This study examined factors that may differentiate placebo responders from nonresponders hospitalized in a structured setting. The sample consisted of 25 children, ages 6.25 to 11.95 years, with CD and a profile of aggressive and explosive behavior, who were assigned to placebo treatment as part of a double-blind study of lithium. Responders were compared to nonresponders with respect to a detrimental psychosocial environmental score, age, IQ, and baseline ratings on the Children's Psychiatric Rating Scale and Clinical Global Impressions. Responders had significantly higher detrimental psychosocial environmental scores than nonresponders; they were particularly more likely to come from violent homes and to have criminally charged parents. Demographic variables did not distinguish the two groups; however, even mild hyperactivity was associated with poorer response to placebo.
