社交恐怖障碍患者执行功能与工作记忆能力研究

探讨社交恐怖障碍患者的执行功能、工作记忆能力与正常对照组的差异.方法 采用威斯康星分类卡片测验(Wisconsin Card Sorting Test,WSCT)以及数字广度、空间广度、多图形空间广度测验对42名社交恐怖障碍患者和42名健康对照者的执行功能、工作记忆能力进行评估.结果 在WSCT测验中,社交恐怖障碍患者非持续错误数明显高于对照组[分别为(18.75±6.20)分,(8.89±3.22)分],差异具有统计学意义.社交恐怖障碍患者工作记忆能力测验中数字广度[分别为(7.25±1.35)分,(8.03 ±2.30)分]、空间广度[分别为(6.11±1.85)分,(8.61±2.87)分]以及多图形空间广度[分别为(4.03±1.39)分,(5.18±1.07)分]成绩均低于对照组,差异具有统计学意义.结论 社交恐怖障碍患者存在工作记忆受损,而这可能是社交恐怖障碍患者学业以及社会功能不良的神经心理学机制.

Abstract：

Objective To explore the executive function and working memory ability of patients with social phobia. Methods The study included 42 social phobia patients whose age, sex, and level of education were matched with those of a healthy control group. Wisconsin Card Sorting Test and Digit Span, Spatial Span, Multiple-Objects-Spatial span were used to study the executive function and working memory. Results Patients with social phobia scored higher than the control group in terms of the number of non perseverative errors on the Wisconsin Card Sorting Test ( 18. 75 ± 6. 20, 8. 89 ± 3. 22 respectively ). No differences were observed in perseverative errors and other scores between the patient and control group. Patients with social phobia scored lower than the control group in terms of Digit Span(7.25 ±1.35,8.03 ±2. 30 respectively) ,Spatial Span(6. 11±1.85,8.61 ±2.87 respectively) and Multiple-Objects-Spatial span(4.03 ± 1. 39 ,5. 18 ± 1.07 respectively). Conclusion Working memory ability in the social phobia patients is impaired, and this may cause the poor performance in patients with the social phobia in academic and social working.
