本研究考察了焦虑与放松和中性思维活动对积极和消极情绪刺激的生理和主观反应的影响。38名广泛性焦虑症（GAD）患者和35名非焦虑对照组患者被随机分配到焦虑、放松或中性诱导组，然后依次接触四个情绪诱导电影片段。这些片段旨在引发恐惧、悲伤、快乐和平静的情绪。自我报告的消极和积极的影响进行了评估后，每个诱导和曝光，并测量迷走神经活动。结果表明，担心（与放松）导致GAD组迷走神经张力降低，以及两组更高的负面影响水平。此外，先前的担心导致对可怕的电影片段的生理和主观反应较少，并且减少了对悲伤片段的负面影响。这表明担心可能通过防止负面情绪对比来避免处理负面情绪。担心情绪回避的作用的影响进行了讨论。
The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed.
