This study investigated the time-course characteristics of attentional bias, such as vigilance and maintenance, towards violent stimuli in dating violence (DV) survivors. DV survivors with PTSD symptoms (DV-PTSD group; n=14), DV survivors without PTSD symptoms (Trauma Control group; n=14), and individuals who were never exposed to dating violence (NDV group; n=15) viewed slides that presented four categories of images (violent, dysphoric, positive, and neutral) per slide, for ten seconds. Our results revealed that the DV-PTSD group spent more time on violent stimuli than did the Trauma Control or NDV groups. The DV survivors, both with and without PTSD symptoms, spent more time on dysphoric stimuli and less time on happy stimuli than did the NDV group. In addition to the effects of PTSD, researchers should also be considering the effects of simple traumatic exposure.
本研究探讨了注意偏向的时程特征，如对暴力刺激的警觉和维持，在恋爱暴力（DV）幸存者中。有创伤后应激障碍症状的 DV 幸存者（DV-PTSD 组；n=14）、无创伤后应激障碍症状的 DV 幸存者（创伤对照组；n=14）和从未遭受过恋爱暴力的个体（未暴露组；n=15）观看了每张幻灯片呈现四种类别的图像（暴力、抑郁、积极和中性），每张十秒钟。我们的结果表明，DV-PTSD 组在暴力刺激上花费的时间多于创伤对照组和未暴露组。有和没有创伤后应激障碍症状的 DV 幸存者在抑郁刺激上花费的时间更多，在快乐刺激上花费的时间更少，比未暴露组。除了创伤后应激障碍的影响，研究人员还应考虑简单创伤暴露的影响。
