Adoption research in The Netherlands
Several universities in The Netherlands conduct scientific research on adoption and/or foster care. This site shows an overview of current and former research.
LeidenAttachment Research Programme: Adoption
In the Leiden Attachment Research Programme adoption is studied from the perspective of attachment theory, as adoption implies the breaking and making of emotional bonds.
Central questions are:
- What are the long-term sequelae of adoption for the adoptees? and
- How can adoptive parents be supported in their difficult task to rear their adopted children?

A Longitudinal Study of Adoption, Attachment, and Problem Behavior
In a prospective, longitudinal study, starting at 6 months of age, maternal sensitivity, early infant-mother attachment and competence were studied in 160 infants adopted from Sri Lanka, South Korea and Colombia. At age 7, a follow-up of the 160 children, plus 30 adoptees recruited at this age, was completed; the attrition rate appeared to be low (8%). In a second follow up at the age of 14 years the adoptive families and the adolescent adoptees have been visited. In the near future a new follow-up study at 21 years of age will be conducted. In the follow-up studies, the adjustment of the adoptees has been assessed, including their cognitive development (IQ and school achievement), their socio-emotional functioning (e.g., peer group popularity), and their problem behaviour.
