“…What is known about trauma in children under 5 years of age comes from several areas including studies on exposure to domestic and interpersonal violence (Groves, 2002;Kitzmann, Gaylord, Holt, & Kenny, 2003;Levendosky, Huth-Bocks, Shapiro, & Semel, 2003;Lieberman, Van Horn, & Ozer, 2005;Osofsky, 1995Osofsky, , 1997, writings on assessment and intervention with young children exposed to violence (e.g., Osofsky, 2004;Scheeringa, Zeanah, Drell, & Larrieu, 1995;Scheeringa, Zeanah, Myers, & Putnam, 2003), intervention studies (Lieberman, Van Horn, & Ippen, 2005), and observational case studies of infants' and toddlers' responses to traumatic events (Drell, Gaensbauer, Siegel, & Sugar, 1995;Gaensbauer, 1995;Sugar, 1993). These writings have demonstrated the potential for detrimental impact of trauma on young children, with greater vulnerability ascribed to younger children (e.g., Kitzmann et al, 2003).…”
