아로마목걸이 착용이 임상실습 중인 간호학생의 지각된 스트레스, 스트레스 증상 및 자율신경계 변화에 미치는 효과

Abstract

Purpose: The purpose of this study was to examine the effects of aroma-necklace application on perceived stress, symptoms of stress and changes in autonomic nervous system among nursing students in clinical training. Methods: A research design for this study was a non-equivalent control group, non-synchronized pre-post test. The experimental group (n = 39) underwent aroma inhalation by necklace which contains an essential oil mixture of lavender and sweet orange mixture in ratio of 2:1 for 2 weeks while the control group (n = 36) received placebo therapy. The data were collected using self-administered questionnaires and measurement of heart rate variability (HRV) and analyzed using the PASW 18.0 program. Results: The perceived stress scores and scores of peripheral manifestations in the experimental group were significantly lower than those of the control group. All indices of HRV were significantly different between the two groups. LF norm and LF/HF ratio in the experimental group were significantly lower than those of the control group, and HF norm in the experimental group was significantly higher than that in the control group. Conclusion: It can be suggested that aroma-necklace application was effective in decreasing perceived stress and peripheral manifestations of stress and in changing HRV indices among nursing students in clinical training.
