放松训练对脑电、情绪的影响及与人格特征的关系

目的:探讨放松训练对脑电、情绪的影响以及与受试者人格、行为类型的关系.方法:68名医科大学生集体进行放松训练2个月,比较训练前后的焦虑自评量表(SAS)和匹兹堡睡眠质量指数(PSQI)得分,评估训练前后脑电、肌电、皮肤温度的变化,以及脑电指标改善程度与受试者个性特征的关系.结果:放松训练后受试者SAS、PSQI得分降低,与训练前相比差异有极显著性意义(t=3.7及5.2,P均<0.01).脑电、肌电、皮肤温度改善,脑电指标改善程度与艾森克个性问卷(EPQ)的N纬度得分、A型行为类型问卷的TH分、总分呈正相关(r=0.25～0.46).结论:放松训练可以改善大学生的生理、心理状况,脑电指标改善程度与受试者的人格特征和行为类型相关.

Effects of Relaxation on EEG,the Personality and Behavior Pattern of Medical Students

Objective:To evaluate the psychosomatic effects of relaxation and the correlation between the effects and the personality and behavior pattern of the subject.Methods:68 medical students were involved in the study. All the subjects received relaxation training for 2 months. They were tested with Self-Rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) before and at the end of the study. They were also tested electroencephalogram (EEG), electromyography (EMG) and skin temperature at the above two time-points. The correlation between the personality and the extents of alteration in index of EEG were also studied.Results:After training, the scores of SAS and PSQI in the subjects were significantly lower than those before training. The indexes of EEG, EMG and skin temperature were improved. The extents of alteration in index of EEG were correlated positively with the N-scores of Eysenck Personality Questionnaire (EPQ), the total scores and TH-scores of Type A Behavior Pattern (TABP).Conclusion:Relaxation can improve psychosomatic states of undergraduates. The extents of alteration in index of EEG were correlated with the personality and behavior pattern of the subject.
