Attentional bias in patients with chronic pain was investigated using the emotional Stroop task with personalized pain words. A group of 20 chronic pain patients with 20 matched controls participated in the experiment. Before administration of the emotional Stroop patients were asked to select the five best descriptors of their pain from a list of 19 sensory pain descriptors. These words were later used in the computerized Stroop test. Also included in the Stroop task were threat words and color words with corresponding control conditions. Apart from the emotional Stroop, measures of pain related distress, anxiety, and depression symptoms were included. Results showed a weak Stroop interference effect with slower reaction times to pain words in the patient group, but they did not differ significantly from the controls. Both groups were slower on the threat words and displayed the classical Stroop interference effect for color words. The overall pattern of results are in line with previous Stroop studies on pain patients showing weak support for the attentional bias hypothesis.
使用带有个性化疼痛词汇的情绪Stroop任务，对慢性疼痛患者的注意偏向进行了研究。一组20名慢性疼痛患者和20名匹配的对照组参与了该实验。在进行情绪Stroop任务之前，要求患者从19个感觉性疼痛描述词列表中选择出最能描述其疼痛的五个词汇。这些词汇随后被用于计算机化的Stroop测试中。Stroop任务中还包括威胁词汇和颜色词汇以及相应的对照条件。除了情绪Stroop任务外，还纳入了疼痛相关痛苦、焦虑和抑郁症状的测量。结果显示，患者组对疼痛词汇的反应时间较慢，存在较弱的Stroop干扰效应，但与对照组无显著差异。两组对威胁词汇的反应都较慢，并且对颜色词汇都表现出经典的Stroop干扰效应。结果的总体模式与之前关于疼痛患者的Stroop研究一致，对注意偏向假说的支持力度较弱。
