社交焦虑障碍患者的注意偏向研究

A study on bias attention of social anxiety disorder

目的探索社交焦虑障碍(SAD)患者注意偏向的特点。方法收集明确诊断为SAD,同时汉密尔顿抑郁量表(HAMD)总分小于20分的患者共30例,并设正常对照组共30例。进行一般人口学资料调查表、Liebowitz社交焦虑量表(LSAS)和数字划销测验检查。结果SAD患者在HAMD、LSAS的得分明显高于对照组(P<0.01)。数字划销测验中,SAD组的粗分158.0±23.6、失误分17.6±12.8、得分140.6±31.7、失误率12.1±12.1,对照组的粗分179.4±13.2、失误分11.3±4.0、得分168.1±13.9、失误率6.3±2.3,两组的差异有统计学意义(P<0.05),其中粗分和得分与LSAS显著相关(P<0.05)。结论社交焦虑障碍患者对数字信息,也会发生注意偏向,注意的偏向与当前关注的内容有关。

Objective： To explore the features of bias attention of patients suffer from social anxiety disorder （SAD）. Methods ： Thirty SAD patients whose Hamilton Rating Scale of Depression （HAMD） scores below 20 were enrolled in test group and the scores of Liebowitz Social Anxiety Scale （LSAS） and Number Cancellation Test were compared with normal controls. Results ： The HAMD, LSAS scores of SAD patients were significantly higher than those of normal controls （P 〈 0.01 ）. The Number Cancellation Test, the total score, missing score, final score and missing rate of SAD patients were respectively 158.0 ± 23.6, 17.6 ±12.8, 140. 6 ±31.7 and 12.1 ± 12.1 while that of normal controls were 179.4 ±13.2, 11.3 ±4.0, 168.1 ± 13.9 and 6. 3 ±2.3. Each couple of results has significant differences between two groups （ P 〈 0.05 ）. The total scores and final scores were negatively correlated with the scores of LSAS （ P 〈 0.05 ）. Conclusion： SAD patients have a deficit in digital information as well as bias attention, while the latter is related to the focus of attention.
