  ABSTRACT: It was the distinguished UK psychiatrist, Professor Sir Michael Rutter, who first promoted the idea that there were risk and protective factors within the wider ecological framework of the child which profoundly influenced the child’s development. This paper based on 20 years of research at the Centre for Research into Parenting and Children at University of Oxford will explore some of these risk and protective factors and demonstrate how it is possible to artificially create protective conditions for those children who do not have them naturally, and to promote their resilience, so necessary in this fast changing world.
