Posttraumatic stress and related symptoms among neglected and physically and sexually maltreated adolescents.

Posttraumatic stress disorder (PTSD) is common among maltreated youth, but few investigations compare neglect with other maltreatment types. This study examined 84 adolescents who experienced neglect only, physical and/or sexual maltreatment only, or neglect with physical and/or sexual maltreatment. Symptoms of PTSD, dissociation, and depression were measured. Adolescents who experienced physical and/or sexual maltreatment, whether neglected or not, reported significantly greater symptomatology than adolescents who experienced neglect only (η2 = .094). This difference applied to PTSD symptoms, dissociative amnesia, depersonalization and derealization, negative mood, and anhedonia. Adolescents exposed to neglect only displayed substantial psychopathology but less than that of other groups. The findings may reflect emerging cascade models of the etiology of symptoms of PTSD following extensive maltreatment history.
