“…There is neither an agreed term nor definition for these children. They have been referred to, for example, as 'troubled and troublesome' (Bullock, Courtney, Parker, Sinclair and Thoburn, 2006) and as the 'most disturbed and difficult children and young people' (Ainsworth and Hansen, 2005). The most conspicuous features of these children's lives are that they have been maltreated or have experienced other acute adversity in their own (family) homes, become looked after as a result (usually in foster homes) but then experience placement breakdown -often because of their challenging behaviour (Boyd, Einbinder, Rauktis and Portwood, 2007;Stanley, Riordan and Alaszewski, 2005).…”
