The major aim of this project is to show that a paradigm found by us to differentiate adults with post-traumatic stress disorder (PTSD) from adults who have had similar experiences but have not developed PTSD can be used to enhance the precision of the PTSD diagnosis in children who have been sexually and/or physically abused. A second aim is to show that physiological measures not only index the degree of distress of abused children but can also be used to separate children with internalizing disorders from those with externalizing disorders. Our paradigms will provide evidence of abnormal nervous system sensitivity, inhibition, attenuated or enhanced startle, and generalization of emotional responses. Over a 5-year period, we propose to screen 600 children (aged 7 to 12 years) who have been abused by someone at least 4 years older than themselves, and who have been referred for abuse-related behavioral and emotional problems. The sample will be limited to non-retarded children. For laboratory studies, we will select subtypes with and without PTSD, matched on the basis of similar experiences, sex, age, and race. A history of victimization form will document stressors: duration and frequency of abuse, number of offenders, relation of perpetrator to child, perception of life threat, physical injury, sexual penetration, social class perpetrator, and family interaction.

这个项目的主要目的是展示我们发现的一个范式 区分患有创伤后应激障碍 (PTSD) 的成年人和成年人 有过类似经历但尚未发展为 PTSD 的人可用于 提高儿童创伤后应激障碍 (PTSD) 诊断的准确性 性虐待和/或身体虐待。 第二个目标是表明 生理测量不仅反映了受虐待者的痛苦程度 孩子们，但也可以用来将孩子与内化分开 那些患有外在疾病的人的疾病。 我们的范式将 提供神经系统敏感性、抑制异常的证据， 减弱或增强的惊吓以及情绪反应的概括。 我们建议在 5 年时间内对 600 名儿童（7 至 12 岁）进行筛查 岁）曾被年长至少 4 岁的人虐待 自己以及因虐待相关行为和行为而被转介的人 情绪问题。 样本仅限于非弱智儿童。 对于实验室研究，我们将选择有或没有 PTSD 的亚型， 根据相似的经历、性别、年龄和种族进行匹配。 一段历史 受害表格将记录压力源：持续时间和频率 虐待行为、犯罪者人数、犯罪者与儿童的关系、对儿童的看法 生命威胁、身体伤害、性侵、社会阶层犯罪者、 以及家人的互动。
