The findings of Romanian Orphan studies has enhanced our understanding of the effects of institutionalisation on attachment. It has led to improvements in the way children are cared for (Langton, 2006).
For example, orphanages and children homes now ensure that a smaller number of people play a central role for the child so that they have a chance to develop normal attachments.
This supports the external validity of the research as it has beneficial application to real life.
