ABSTRACT This study examines the behavior problems of children receiving services through an adoption preservation program for legally adopted children at risk of placement or dissolution. Two measures of behavior problems are used: a behavior problem rating scale, available on 368 children, and the Child Behavior Checklist, available on 201 children. Variables associated with severity of behavior problems include attachment problems, age at placement, experiencing multiple types of abuse and neglect, a history of sexual abuse, and experiencing a recent loss in the family. Children's scores on the CBC reflect the severity of behavioral and emotional problems among these children who have lived in their adoptive home for a mean of 8.9 years. Ninety-one percent score in the clinical range on at least one of the three summary scores of the CBC. These findings support the need for services for children and families beyond the ilnalization of adoption.
