摘  要:目的探讨躯体形式障碍患者对情绪图片信息的认知偏倚。方法用SAS和SDS评定30例躯体形式障碍患者(试验组)及30例健康志愿者(对照组)焦虑、抑郁的严重程度,并行情绪图片刺激的点探测任务检测。结果两组在SAS、SDS分值比较上差异均有显著性(P<0.01)。重复测量方差分析表明,平均反应时的组间水平主效应显著(F=8.749,P=0.006);探测点与情绪图片位置的一致性主效应显著(F=16.896,P=0.000)。试验组对负性情绪图片的不同探测位置上的反应时差异有显著性(P=0.001),对负性情绪图片刺激的注意偏向分高于正性,组间、组内差异均有显著性(F=19.876、16.829,P=0.000、0.000)。结论躯体形式障碍患者的负性情绪较为明显,其所患疾病影响了个体对情绪信息的注意,对负性情绪图片刺激存在注意偏倚。【Objective】To investigate the attentional bias to affective pictures in patients with somatoform disor- ders(SD) under the dot-probe task.【Methods】A total of 30 patients with somatoform disorders(SD group) and 30 health volunteers(control group) were involved. Zung's SAS and SDS assess the severity of anxiety and depression in two groups. All participants measured with dot-probe task of affective pictures. 【Results】There were statistically significant differences(P 0.01) when SD group's SAS and SDS scores compared with the control group's. Repeated measures ANOVA analysis showed that a significant main effect of the average response time level between the two groups(F =8.749, P =0.006); the consistency of dot-probe with the affective pictures' position showed a significant main effect(F =16.896, P =0.000). The difference about SD group's response time was statistically significant(P = 0.001) when the probe position was inconsistent with the negative emotion pictures. SD group's attentional bias points to the negative emotion pictures were higher than to the positive ones'. The difference between the two groups was statistically significant(F =19.876, P =0.000) as well as within the two groups(F =16.829, P =0.000).【Conclu- sions】There were more obvious negative emotions in patients with somatoform disorders, the disease which the SD group was suffering from affected the individual's attention to the affective information. Somatoform disorders have attentional bias to negative affective pictures.
