目的:研究脑血管状态与人格特征的相关性。方法:人格特征应用A型行为类型量表、艾森克人格问卷(EPQ)对60名20-35岁青年人群进行问卷调查,并划分出不同类型;脑血管状态应用经颅多普勒超声(TCD)的诊断技术测查60人的大脑中动脉(MCV)的血流速度来判断脑血管的紧张程度。结果:脑血管紧张组:A型人格为19人占59.3%,对照组:A型人格为3人占10.7%,以A型人格占优势(x2=22.85,P<0.01)。脑血管紧张组(36.2±5.8)A型行为问卷平均得分高于对照组(20.3±2.4))(t=6.81,P<0.01)。脑血管紧张组P分、N分、L分与正常对照组比较,差异无统计学意义(均P>0.05);脑血管紧张组E分(内外向)高于对照组,差异有统计学意义(P<0.05)。四种性格类型相比,外向情绪不稳定型的脑血管紧张组13(40.6%)与对照组4(14.3%)相比所占比例较高(x2=21.91,P<0.05)。结论:A型人格,外向不稳定的人格特征与脑血流速度增快有关,可能是脑血管紧张的诱发因素之一。
Objective: To study the correlation between cerebrovascular status and personality traits. Methods: Personality traits A type of behavior type scale, Eysenck Personality Questionnaire (EPQ) 60 young people aged 20-35 were surveyed and divided into different types; cerebral vascular status using transcranial Doppler ultrasound TCD) diagnosis of 60 people in the middle cerebral artery (MCV) blood flow velocity to determine the degree of cerebral vascular tension. Results: In cerebrovascular tension group, type A personality was 19.3%, while in control group, type A personality was 10.7%. Type A personality predominance (x2 = 22.85, P <0.01). The average score of type A behavioral questionnaire in cerebral vascular group (36.2 ± 5.8) was higher than that in control group (20.3 ± 2.4) (t = 6.81, P <0.01). Cerebral vascular tension group P points, N points, L points compared with the normal control group, the difference was not statistically significant (P> 0.05); cerebrovascular tension group E points (inward and outward) was higher than the control group, the difference was statistically significant (P <0.05). Compared with the four personality types, 13 (40.6%) in the extroverted erratic type of cerebrovascular tension group had a higher proportion (14.2%) than the control group (14.3%) (x2 = 21.91, P <0.05). Conclusion: Personality trait of type A personality and extroversion is related to the increase of cerebral blood flow velocity, which may be one of the inducing factors of cerebrovascular tension.
