This project's objective is to test the validity of the post-traumatic stress disorder (PTSD) diagnosis as the result of childhood sexual abuse, by utilizing an assessment method that has been validated in PTSD arising from other (military and civilian) sources in four previous studies, viz., measurement of physiologic responses during personal, script-driven imagery. The responses of medication-free, adult women during imagery of their personal sexual abuse experiences as children will be measured. Subjects will be diagnosed into PTSD, past-PTSD, and non-PTSD groups. Thirty- second "scripts" will be prepared with the aid of the subject describing various past life experiences, including specific episodes of child sexual abuse. The scripts will incorporate subjective visceral and muscular reactions that the subject remembered accompanied each experience. The scripts will be recorded for playback in the psychophysiology laboratory, where the subject will be instructed to imagine the events the scripts portray, while heart rate, skin conductance, and facial muscle electromyograms are recorded. The data will be analyzed by means of multivariate analysis of variance (MANOVA) and discriminant function analysis. The role of potentially confounding variables will be assessed by means of multivariate analysis of covariance (MANCOVA), with factors such as overall trauma exposure, face severity of the specific abuse episodes studied, anxiety, depression, dissociation, and hypnotic suggestibility used as covariates. Data from a subset of subjects with substantiated abuse episodes will be examined separately and the results compared with those from the full data set. In addition, the physiologic responses of the child abuse subjects will be compared with the responses of military and civilian, PTSD and non-PTSD trauma victims already studied with the same methodology. The success of a discriminant function derived from published studies with earlier subjects in classifying PTSD and non-PTSD child abuse subjects will be examined.

该项目的目的是测试创伤后恢复的有效性 由于童年性虐待而被诊断为应激障碍（PTSD）， 利用已在 PTSD 中得到验证的评估方法 在之前的四项研究中来自其他（军事和民用）来源， 即，在个人的、脚本驱动的过程中测量生理反应 图像。 未接受药物治疗的成年女性在想象自己的情况时的反应 儿童时期的个人性虐待经历将被衡量。 科目 将被诊断为 PTSD、过去 PTSD 和非 PTSD 组。 三十- 第二个“脚本”将在描述主题的帮助下准备 各种过去的生活经历，包括儿童时期的特定经历 性虐待。 剧本将包含主观的本能和 受试者记得伴随着每一次的肌肉反应 经验。 脚本将被记录下来以便在 心理生理学实验室，受试者将被指示 想象剧本描绘的事件，同时心率、皮肤 记录电导和面部肌肉肌电图。 将通过多元方差分析对数据进行分析 （多元方差分析）和判别函数分析。 潜在的作用 将通过多变量分析来评估混杂变量 协方差（MANCOVA），与整体创伤暴露等因素相关， 面对所研究的特定虐待事件的严重程度、焦虑、 抑郁、解离和催眠暗示性用作协变量。 来自具有已证实的虐待事件的受试者子集的数据将被 分别进行检查，并将结果与​​完整的结果进行比较 数据集。 此外，虐待儿童的生理反应 受试者将与军事和民间的反应进行比较， PTSD 和非 PTSD 创伤受害者已经用相同的方法进行了研究 方法论。 判别函数的成功源自 已发表的早期受试者对 PTSD 和非 PTSD 进行分类的研究 虐待儿童主题将受到审查。
