“…Findings from this literature on residential programs, generally, indicate that the youth served experience a range of psychiatric disorders and high rates of comorbidity (Conner, Doerfler, Toscano, Volungis, & Steingard, 2004). Further, many youth in residential programs (50–70%) have experienced at least one type of trauma (e.g., physical abuse; sexual abuse; community violence) (Bettmann, Lundahl, Wright, Jasperson, & McRoberts, 2011; Boyer, Hallion, Hammell, & Button, 2009; Jaycox, Ebener, Damesek, & Becker, 2004; Warner & Pottick, 2003), including high rates of maltreatment (Hussey & Guo, 2002; James, Zhang, & Landsverk, 2012). Studies also indicate that the greater complexity of maltreatment histories (i.e., more incidents and/or types of maltreatment experienced) seen among youth in residential programs as compared to the general population (e.g., Costello, Erkanli, Fairbank, & Angold, 2002) contributes to higher risk for multiple diagnoses (e.g., Copeland, Keeler, Angold, & Costello, 2007; D’Andrea, Ford, Stolbach, Spinazzola, & van der Kolk, 2012).…”
