摘要

目的：本研究針對重症加護病房護理人員，設計一個生理回饋訓練模式，研究其對焦慮反應的影響效果。
方法；研究採取等組前後測設計，以某醫學大學重症加護病房護理人員，招募志願者二十人接受實驗，隨機分派到實驗組與控制組。實驗組施予八週之生理回饋訓練，採用的主要生理回饋指標為膚電流、指溫。除透過電腦軟體記錄每次訓練過程的膚電流、指溫、肌電位、心跳速率與呼吸速率等生理數據變化之外，並於實驗前後測量其在貝克焦慮量表(BAI)的得分。控制組則僅接受生理指標與量表的前後測，以實驗組與控制組的差異，考驗生理回饋訓練對焦慮反應的影響效果
結果：經共變數分析顯示，本研究配合生理回饋的放鬆訓練，對於實驗對象的放鬆效果，能降低實驗對象自陳的焦慮反應，但在生理指標的變化方面並不顯著，且不同生理指標之間，並未有一致的傾向。較符合預期結果的是膚電流、指溫與心跳速率這三種生理指標的變化方向。
結論：透過本研究之文獻探討與實徵研究，針對焦慮反應的身心醫學模式與生理回饋訓練效果的機制加以討論，以利進一步的研究探討與臨床上的應用。

Purpose: The purpose of this study was to explore the effects of biofeedback training on the anxiety levels in nurses working in ICU.
Method: The subjects consisted of twenty nurses working at Chung Shan Medical University Hospital. These volunteers were recruited from the ICU of the hospital and were randomly assigned to the experimental group and control group. EMG, GSR, finger temperature, BVP and respiratory rate were used as indices of biofeedback training. Subjects in experimental group completed an 8-week biofeedback training program. The Beck Anxiety Inventory (BAI) was administered to the participants before and after the training program. The control group was also administered the BAI before and after the study period.
Results: ANCOVA revealed that, by the end of the study period, the experimental group has significantly lower BAI scores than the control group, though when considering the indices separately, the two groups did not have significantly different scores on any index. The changing pattern of GSR, finger temperature, and heart rate were more congruent with the expectation than EMG and BVP.
Conclusions: The methods used in this study can be applied to further research into the effects of relaxation techniques for health care personnel.
