The physiological response to trauma-related stimuli of up to one third of participants with posttraumatic stress disorder (PTSD) cannot be discriminated from that of controls. Psychophysiological measures (heart rate and blood pressure) of 22 PTSD and 23 control civilian participants, all exposed to missile attacks during the Gulf War, were recorded while listening to five scripts. The physiological response of PTSD subjects with high image control (IC) was lower than that of PTSD participants with low IC and similar to that of non-PTSD subjects. The physiological response poorly discriminated high IC PTSD participants from controls, but was successful in discriminating low IC PTSD subjects from controls with 91% specificity and 92% sensitivity. Image control is proposed as a function influencing physiological response in PTSD.
高达三分之一的创伤后应激障碍（PTSD）患者对创伤相关刺激的生理反应无法与对照组区分开来。在22名PTSD平民患者和23名对照平民参与者听五个脚本时，记录了他们的心理生理指标（心率和血压），这些参与者在海湾战争期间都遭受过导弹袭击。高图像控制（IC）的PTSD患者的生理反应低于低IC的PTSD参与者，且与非PTSD患者相似。生理反应很难区分高IC的PTSD参与者和对照组，但成功地以91%的特异性和92%的敏感性区分了低IC的PTSD患者和对照组。图像控制被认为是影响PTSD生理反应的一个因素。
