【摘要】 目的:比较有无自杀方式的大学生脑象图特征。方法:测试64名有自杀方式的大学生和90名无自杀方式的大学生在平静、运算、慢节奏音乐和快节奏音乐状态下的脑象图指标,对两组的差异进行统计分析。结果:平静、运算、快节奏音乐状态下,有自杀方式组顶叶、颞叶、额叶、枕叶(P4、T3、F7、Fz、O1)的抑郁值或焦虑值显著高于无自杀方式组(P<0.05);平静、快节奏音乐状态下,有自杀方式组颞叶(T5、T3)的锁定值显著高于无自杀方式组,但在运算状态下其左额极(Fp1)的锁定值显著低于无自杀方式组(P<0.05),同样状态下有自杀方式组左额叶(F3)的中心集结值也是如此;慢节奏音乐状态下有自杀方式组左中颞(T3)的逃逸值更高,但慢节奏和快节奏音乐状态下左额区(F3、F7)的逃逸值更低(P<0.05);平静状态下,有自杀方式组额中线(Fz)的过稳态值显著低于无自杀方式组(P<0.05)。结论:有自杀方式的大学生焦虑和抑郁情绪更明显,易出现负面情绪和思维的固着状态,意识回归能力减弱;但在理性思维状态下有自杀方式的大学生更少纠结,不易受环境影响,做决定更为果断。反映出有自杀方式的大学生自杀风险性更高。更多还原

【Abstract】 Objective: To compare the features of electroencephalonquadrantogram(EEQG) of college students with and without suicide methods. Methods: The indicators of EEQG of 64 college students with suicide methods and 90 college students without suicide methods in calm state, calculating state, slow-tempo music state and fast-tempo music state were tested, and the differences between the two groups were statistically analyzed. Results: In the calm state, calculating state and fast-tempo music state, the depression or anxiety values of the parietal lobe, temporal lobe, frontal lobe and occipital lobe(P4, T3, F7, Fz, O1) in the group with suicide methods were significantly higher than those in the group without suicide methods(P<0.05). In the calm state and fasttempo music state, the locking value of the temporal lobe(T5, T3) in the group with suicide method was significantly higher than that in the group without suicide methods(P<0.05). But in the calculating state, the locking value of the left frontal pole(Fp1) showed the opposite result. In the same state, the central concentration value of the left frontal lobe(F3) in the group with suicide methods also showed the same result. The escape value on the left middle temporal(T3) under slow-tempo music state in the group with suicide methods was higher, but the escape value on the left frontal area(F3, F7) under slow-tempo and fast-tempo music state was lower(P<0.05). In the calm state, the overstable state value on the frontal midline(Fz) in the group with suicide methods was significantly lower than that in the group without suicide methods(P<0.05). Conclusion: The anxiety and depression of college students with suicide methods are more obvious, and they are prone to the fixation of negative emotions and thinking, and the ability of consciousness return is weakened, but under the rational thinking state, college students with suicide methods are less tangled, not easily affected by the environment, and make decisions more decisively. It shows that college students with suicide methods are more likely to commit suicide.更多还原
