Children from disrupted and adoptive homes on an inpatient unit.

Among 375 children and adolescents admitted to a psychiatric hospital inpatient unit, the proportion of adopted children was considerably higher than that of a general pediatric population or of census figures, and the majority of nonadoptees were from disrupted homes. Based on a review of case records, adoption and family disruptions appear to increase significantly the length of hospitalization and to shift diagnoses toward behavioral disturbances. Implications for prevention and treatment are considered.
