目的探讨慢性疼痛患者对痛觉相关信息是否存在注意偏向.方法采用E-prime 2.0程序编写情绪Stroop范式,记录并比较慢性疼痛患者及健康对照组(各20例)对3类词汇(包括中性、痛觉、威胁)颜色命名的反应时及正确率,考察慢性疼痛患者的注意偏向.结果慢性疼痛患者对痛觉相关词汇的颜色命名反应时长于中性词汇[(786.02±18.15) ms vs (774.73±17.34) ms,P<0.05],威胁相关词汇反应时长于中性词汇[(792.35±17.72) ms vs (774.73±17.34) ms,P<0.05];健康对照组威胁相关词汇反应时长于中性词汇[(779.75±20.99) ms vs (764.74±20.53) ms,P<0.05],对痛觉相关词汇的颜色命名反应时与中性词汇无统计学差异.重复测量方差分析发现存在刺激类别的主效应(F=18.86,P<0.01),以及组别和刺激类别的交互效应(F=4.48,P<0.05).慢性疼痛患者痛觉相关词汇注意偏向与疼痛持续时间无关,与患者焦虑水平显著相关(r=0.471,P<0.05).结论慢性疼痛患者存在对痛觉相关信息的注意偏向,并且与焦虑水平有密切关系.

Objective To study the attention biases to pain-related information in chronic pain patients. Methods Attention biases in 20 chronic pain patients and 20 healthy controls to pain-related words were recorded with E-prime 2.0 program, Stroop task. Results The reaction time (RT) to pain-related words and threaten words was longer than to neutral words in chronic pain patients (786.02±18.15 ms vs 774.73 ±17.34 ms, 792.35±17.72 ms vs 774.73±17.34 ms, P<0.05). The RT to threaten-related words was longer than to neutral words in healthy controls (779.75±20.99 ms vs 764.74±20.53 ms, P<0.05) whereas no significant difference was found in pain-related words and neutral words. Variance analysis showed a dominant effect of stimulation types (F=18.86, P<0.01) and an interactive effect between group types and stimulation types (F=4.48,P<0.05). Pain-related words were not related with pain-lasting time but with anxiety in chronic pain patients with attention biases(r=0.471, P<0.05). Conclusion Chronic pain patients suffer attention biases to pain-related information, which is significantly related to their anxiety.
