This is because the ban on contraception meant that Romanian orphanages were full and, given the low numbers of staff, this led to poor standards of care. This is a limitation because it may mean that the effects of institutionalisation would have been more severe In Romanian orphanages than they would have been in other institutions e.g. orphanages in Britain that had better standards of care. As a result, the effects of institutionalisation may have been exaggerated.
