RESULTS:
Children in the study had exceptionally poor mental health and socialization, both in absolute terms, and relative to normative and in-care samples. Levels and rates of disturbance for children in foster care exceeded all prior estimates. Rates of disturbance for children in kinship care were high, but within the range of prior estimates. Boys presented with higher scope and severity of mental health problems than girls on the CBCL, while gender-specific patterns of disturbance were shown on the ACC. A moderate age effect was accounted for by children's age at entry into care.

CONCLUSIONS:
Children in care are at high risk of mental health problems. Psychological support for the children and their carers is an essential secondary prevention strategy. Implications for service delivery are discussed.
