“…The importance of early relationships in the development of these skills was emphasized in a recent report by the National Research Council’s Institute of Medicine (Shonkoff & Phillips, 2000): “The scientific evidence on the significant developmental impacts of early experiences, caregiving relationships, and environmental threats is incontrovertible.” Not surprisingly, recent data indicate that a large proportion (as high as 61%) of young children in CW exhibit developmental and behavioral deficits (Reams, 1999), in sharp contrast to the much smaller proportion (10–12%) of children in the general population who exhibit such deficits (First & Palfrey, 1994). Delays in toddlers and preschoolers in CW appear in a variety of domains including developmental and cognitive skills (Egeland & Sroufe, 1981; Kinard, 1999; Klee, Kronstadt, & Zlotnick, 1997; Landsverk, Davis, Ganger, & Newton, 1996; Zimmer & Panko, 2006), language skills (Allen & Oliver, 1982; Coster, Gersten, Beeghly, & Cicchetti, 1989; Simms, 1989), behavior problems (Leslie, Gordon, Ganger, & Gist, 2002; Reams, 1999; Simms, 1989; Stahmer et al, 2005; Urquiza, Wirtz, Peterson, & Singer, 1994), and adaptive skills (Stahmer et al, 2005; Horwitz, Balestracci, & & Simms, 2001). Although most studies have addressed children residing in out-of-home care, recent data suggest that similar levels of need are seen in young children who remain at home (Leslie et al, 2002; Stahmer et al, 2005).…”
