健康焦虑与注意偏差：根据图画疾病信息的警觉和回避的时间进程关键词：点探测任务选择性注意注意偏向健康焦虑症焦虑症焦虑敏感度a S健康焦虑的认知行为模型强调选择性注意的重要性，不仅对内部的，而且对外部的健康威胁相关刺激。然而，人们对这种注意力偏向的时间进程知之甚少。本研究调查了具有不同程度健康焦虑的参与者中与威胁相关的注意偏差。在175ms和500ms两种曝光时间下，使用有健康威胁和中性图片的视觉点探头任务来评估注意偏向。在点探测任务中增加了一个基线条件，以分离对威胁的警惕指数和脱离威胁的困难指数。在500ms的暴露时间内，健康焦虑、焦虑敏感性和注意力与摆脱威胁的困难之间存在显著的正相关。在早期阶段(即，在175ms暴露时间)，我们发现健康焦虑和吸收与对威胁的定向显著正相关。结果提示，在健康焦虑中存在一种与图画疾病相关刺激相关的选择性注意的警戒回避模式。
Health anxiety and attentional bias: The time course of vigilance and avoidance in light of pictorial illness information Keywords: Dot-probe task Selective attention Attentional bias Health anxiety Hypochondriasis Anxiety sensitivity a b s t r a c t Cognitive-behavioral models of health anxiety stress the importance of selective attention not only towards internal but also towards external health threat related stimuli. Yet, little is known about the time course of this attentional bias. The current study investigates threat related attentional bias in participants with varying degrees of health anxiety. Attentional bias was assessed using a visual dot-probe task with health-threat and neutral pictures at two exposure durations, 175 ms and 500 ms. A baseline condition was added to the dot-probe task to dissociate indices of vigilance towards threat and difficulties to disengage from threat. Substantial positive correlations of health anxiety, anxiety sensitivity, and absorption with difficulties to disengage from threat were detected at 500 ms exposure time. At an early stage (i.e., at 175 ms exposure time), we found significant positive correlations of health anxiety and absorption with orientation towards threat. Results suggest a vigilance avoidance pattern of selective attention associated with pictorial illness related stimuli in health anxiety.
