Myung Ja Kim,1Eun Sook Nam, and Seun In Paik

Abstract

Purpose
The purpose of this study was to investigate the effect of aromatherapy on pain, depression, and feelings of satisfaction in life of arthritis patients.

Method
This study used a quasi-experimental design with a non-equivalent control group, pre-and post-test. The sample consisted of 40 patients, enrolled in the Rheumatics Center, Kangnam St. Mary’s Hospital, South Korea. The essential oils used were lavender, marjoram, eucalyptus, rosemary, and peppermint blended in proportions of 2:1:2:1:1. They were mixed with a carrier oil composed of almond (45%), apricot(45%), and jojoba oil(10%) and they were diluted to 1.5% after blending. The data were analyzed using a 2-test, Fisher’s exact test, t-test and paired t-test.

Result
Aromatherapy significantly decreased both the pain score and the depression score of the experimental group compared with the control group. However, aromatherapy didn’t increase the feeling of satisfaction in life of the experimental group compared with the control group.

Conclusion
The result of this study clearly shows that aromatherapy has major effects on decreasing pain and depression levels. Based on our experiment’s findings, we suggest that aromatherapy can be a useful nursing intervention for arthritis patients.
