慢性呼吸困难的患者可能会学会害怕导致呼吸困难发作的情况。这种特定于呼吸困难的线索可能会导致焦虑，甚至在开始体力活动之前就会恶化或引发呼吸困难。因此，我们开发了一种实验工具来探索呼吸困难的情绪处理，以便与COPD的神经成像一起使用。该工具由一项计算机化的任务组成，该任务包括多个与呼吸困难相关的单词线索的呈现，以及随后使用视觉模拟量表对呼吸困难和呼吸困难-焦虑进行评级。经过3个发展阶段，对34例接受肺康复治疗的COPD患者进行了对临床变化的敏感性测试。我们用已建立的呼吸困难测量方法(包括呼吸困难-12)测量内部一致性、对临床变化的敏感度和收敛。克朗巴赫的阿尔法呼吸困难评分为0.90，焦虑评分为0.94。呼吸困难评分与呼吸困难相关(呼吸困难：r=0.51P=0.002；焦虑：r=0.54P=0.001)。肺康复后焦虑评分的降低与呼吸困难-12评分的降低相关(r=0.51P=0.002)。我们的结论是，单词线索任务是可靠的，因此是一种潜在的有用工具，用于神经成像呼吸困难的研究。(C)2016年提交人。爱思唯尔出版公司(Elsevier B.V.)
Patients with chronic dyspnoea may learn to fear situations that cue dyspnoea onset. Such dyspnoea-specific cues may then cause anxiety, and worsen or trigger dyspnoea even before commencement of physical activity. We therefore developed an experimental tool to probe emotional processing of dyspnoea for use with neuroimaging in COPD. The tool consists of a computerised task comprising multiple presentations of dyspnoea-related word cues with subsequent rating of dyspnoea and dyspnoea-anxiety with a visual analogue scale. Following 3 development stages, sensitivity to clinical change was tested in 34 COPD patients undergoing pulmonary rehabilitation. We measured internal consistency, sensitivity to clinical change and convergence with established dyspnoea measures (including Dyspnoea-12). Cronbach's alpha was 0.90 for dyspnoea and 0.94 for anxiety ratings. Ratings correlated with Dyspnoea-12 (dyspnoea: r=0.51, P=0.002; anxiety: r=0.54, P=0.001). Reductions in anxiety ratings following pulmonary rehabilitation correlated with reductions in Dyspnoea-12 (r = 0.51, P = 0.002). We conclude that the word-cue task is reliable, and is thus a potentially useful tool for neuroimaging dyspnoea research. (C) 2016 The Authors. Published by Elsevier B.V.
