Abstract
The heterogeneity of the group of adopted children does not allow to draw general conclusions about the nature and quantity of behavioral problems with adopted children. This nature and quantity depend on the chosen comparison group. Older foreign adoptees at placement often show complex physical and psychological problems. Many suffer from some kind of behavioral disturbances. Empirical data show that reactive attachment disorder (RAD) can often be diagnosed. The continuation of this disorder in adulthood will result infeelings of psychic homelessness. Examples are described to make clear what kind of behavioral problem it concerns. Research to select appropriate treatments for RAD and psychic homelessness is still lacking.
