This collection of articles summarizes what mental health professionals have learned about evaluating and treating infants and young children who have been exposed to violence in their homes and communities. Emphasis is on recognizing symptoms and behaviors demonstrated by very young children who have been exposed to violence, supporting caregivers of traumatized young children, and designing and carrying out treatment plans. Following an introduction by Joy D. Osofsky, the following articles are offered: (1) "Evaluation of Posttraumatic Symptomatology in Infants and Young Children Exposed to Violence" (Charles H. Zeanah and Michael Scheeringa), which describes the range of symptoms and behaviors typically seen in these children; (2) "Developmental and Therapeutic Aspects of Treating Infants and Toddlers Who Have Witnessed Violence" (Theodore Gaensbauer), which uses a detailed case example to illustrate the evaluation and treatment process; (3) "Trauma Reverberates: Psychosocial Evaluation of the Caregiving Environment of Young Children Exposed to Violence and Traumatic Loss" (Marva L. Lewis), which offers a comprehensive approach to evaluating the child's environment; (4) "Children without Refuge: Young Witnesses to Domestic Violence" (Betsy McAlister Groves), which addresses issues in the evaluation process such as the tension between the needs of children and adults; and (5) "When the Helper Is Hurting: Burnout and Countertransference Issues in Treatment of Children Exposed to Violence" (Joy D. Osofsky), which offers guidelines for training and supporting front-line clinicians and collaborating effectively with other community professionals.
