这项多地点研究测试了心理生理反应的能力，以预测创伤后应激障碍（PTSD）的诊断（当前，终身，或从未）在一个大样本的男性越南退伍军人。逻辑回归方程的预测变量来自一个挑战性的任务，包括战斗场景。该公式经过测试和交叉验证，证明了约2/3的当前和从未PTSD参与者的正确分类。结果复制了当前PTSD患者对创伤相关线索的心理生理反应增强的发现，以及有和没有这种疾病的群体之间在各种其他领域的差异。后续分析表明，目前患有PTSD的退伍军人对挑战任务没有生理反应，表现出较少的重复经历症状，抑郁和内疚。讨论解决的价值心理生理措施评估创伤后应激障碍。
This multisite study tested the ability of psychophysiological responding to predict posttraumatic stress disorder (PTSD) diagnosis (current, lifetime, or never) in a large sample of male Vietnam veterans. Predictor variables for a logistic regression equation were drawn from a challenge task involving scenes of combat. The equation was tested and cross-validated, demonstrating correct classification of approximately 2/3 of the current and never PTSD participants. Results replicate the finding of heightened psychophysiological responding to trauma-related cues by individuals with current PTSD, as well as differences in a variety of other domains between groups with and without the disorder. Follow-up analyses indicate that veterans with current PTSD who do not react physiologically to the challenge task manifest less reexperiencing symptoms, depression, and guilt. Discussion addresses the value of psychophysiological measures for assessment of PTSD.
