The children, aged 7 to 13 years, were referred to the project from several sources at Arkansas Children's Hospital and from associated local agencies. The victims and caregivers were separately administered the Diagnostic Interview for Children and Adolescents, Revised Version (DICA). Additionally, caregivers and classroom teachers completed the Child Behavior Checklist (CBCL). Characteristics of the abuse were obtained from an investigative questionnaire. Both victims and caregivers endorsed high rates of disorders, with caregivers generally giving higher rates than children, and boys having more externalizing diagnoses than girls. Children who had experienced both physical and sexual abuse had more diagnoses overall. Concordance between victims and caregivers was modest. Post traumatic stress disorder was significantly comorbid with most affective disorders. On the CBCL, caregivers rated girls less disturbed than boys and the sexually-abused-only group less disturbed than the other groups. Teachers rated the boys more adversely than girls but did not see differences by abuse group. A younger age of onset of sexual abuse and coercion to maintain secrecy predicted a higher number of total diagnoses. Also, children who were physically abused by males had more diagnoses than those physically abused by females. The study concludes that children who have been both physically and sexually abused appear to be at highest risk of psychiatric disturbance. Post traumatic stress disorder, although common (approximately one-third of victims), is generally comorbid with other affective disorders. 12 tables and 41 references
