“…Although a family-environment is preferred for every child, noninstitutional community-based treatment and/or living in a foster home can be extremely difficult for children showing persistent aggressive and anti-social behaviour, with a risk for frequent placement disruptions (Dekker, Van Miert, Roest, & Van der Helm, 2012;Jakobsen, 2013;Oosterman, Schuengel, Slot, Bullens, & Doreleijers, 2007;Van Oijen, 2010). The prevalence of placement instability should not be underestimated; it can aggravate emotional and behavioural problems (Barber & Delfabbro, 2003;Hussey & Guo, 2005;James, Landsverk, Slymen, & Leslie, 2004;Rubin, Alessandrini, Feudtner, Localio & Hadley, 2004;Ryan & Testa, 2005).…”
