生物反馈疗法对大学生考试焦虑的治疗作用

探讨生物反馈疗法对大学生考试焦虑的治疗作用。在某大学随机抽取学生1500名，采用考试焦虑量表进行筛查，选取焦虑组和对照组各30名。利用生物反馈疗法进行干预，采用脑电α波相对功率、肌电和皮电导联进行检测，每周2次，持续4周。结果表明：1.经过4周的干预，焦虑组干预前后各生理指标存在差异；2.生物反馈疗法干预考试焦虑在疗效上存在性别差异。结论：生物反馈疗法能有效降低大学生考试焦虑水平，对其治疗取得良好的效果。

An Experimental Study of Biofeedback Therapy on Intervention for Test Anxiety of University Students

Objective: The use of biofeedback therapy on intervention for test anxiety in university students. Methods: In this study, we selected randomly a comprehensive university of 1,500 students using the Test Anxiety Inventory (Test Anxiety scale, TAS) for evaluation, according to survey results, who were divided into two groups: anxiety group ( n = 30) and control group ( n = 30).The anxiety group and control group respectively received 40 minutes biofeedback intervention 2 times per week for 4 weeks. The use of Physiological indicators including EEG relative power a wave, electromyography (EMG) and skin conductance(SC) were detected together. Results : 1. After 4 weeks of continuous treatment, anxiety group received before and after intervention α wave EEG relative power, electromyography (EMG), and skin conductance exists differences; 2. Anxiety group of students before and after treatment on the physiological significance also exist; 3. Biofeedback therapy for test anxiety in different from the sexes, girls superior to boys. Conclusion: Biofeedback therapy can effectively reduce the level of test anxiety in university students.
