改良的斯特鲁普和点探测任务的结果提供了关于慢性疼痛患者感觉和影响疼痛刺激的注意力偏差的混合证据。没有研究比较同一组慢性疼痛参与者和健康对照参与者在这两项任务上的情况。我们对 36 名患有慢性肌肉骨骼疼痛的患者和 29 名健康对照受试者进行了改良 Stroop 和点探测任务的测试。刺激包括情感疼痛、感觉疼痛、身体灾难和中性词语。没有证据表明患者和对照受试者在修改后的斯特鲁普任务中对威胁线索的处理存在差异。然而，所有参与者确实表现出了对情感痛苦词的不同处理。这在屏蔽和未屏蔽的演示格式上都很明显。对于从点探测任务中得出的任何选择性注意力指数，临床状态和威胁词类型之间没有观察到显着的相互作用，但所有参与者都很难将注意力从情感痛苦和健康灾难词中分离出来。研究结果不受情绪、焦虑或对疼痛的恐惧的个体差异的影响。对标准（未掩蔽的）斯特鲁普干扰指数和选择性注意的点探针指数的相关分析显示，始终缺乏显着关联，这表明这两项任务可能正在测量不同的现象。总而言之，这些发现提供的证据表明，慢性疼痛患者和健康对照参与者在关注威胁性语言刺激的方式上没有差异。观点：一些慢性疼痛患者可能难以注意除了疼痛的情感成分和相关的灾难性健康后果之外的任何事情。专门针对这种注意力固定性的干预措施可能有助于将注意力转移到其他目标，从而减少特定于疼痛的焦虑和恐惧。 (c) 2005 年，美国疼痛协会。
Results from modified Stroop and dot-probe tasks have provided mixed evidence regarding attentional biases for sensory and affect pain stimuli in chronic pain patients. No studies have compared the same groups of chronic pain and healthy control participants on both tasks. We tested 36 patients with chronic musculoskeletal pain and 29 healthy control subjects on the modified Stroop and dot-probe tasks. Stimuli comprised affect pain, sensory pain, physical catastrophe, and neutral words. There was no evidence to suggest differential processing of threat cues by patients and control subjects on the modified Stroop task. All participants did, however, show differential processing of affect pain words. This was evident on both masked and unmasked presentation formats. There were no significant interactions between clinical status and threat word type observed for any of the indices of selective attention derived from the dot-probe task, but all participants had difficulty disengaging attention from affective pain and health catastrophe words. Findings were not influenced by individual differences in mood, anxiety, or fear of pain. Correlational analyses of the standard (unmasked) Stroop interference index and dot-probe indices of selective attention revealed a consistent lack of significant association, suggesting that the 2 tasks might be measuring different phenomena. Taken together, these findings provide evidence that chronic pain patients and healthy control participants do not differ in the way they attend to threatening linguistic stimuli.Perspective: Some patients with chronic pain might have trouble paying attention to anything other than the affective components of pain and associated catastrophic health consequences. Interventions that specifically target this attentional fixedness might facilitate shifting attention to other targets and thereby reduce pain-specific anxiety and fear.
