Purpose: The purpose of this study was to evaluate the effectiveness of a sleep improvement program combined with an aroma-necklace onsleep, depression, anxiety, and blood pressure in elderly women living at home. Methods: A program consisting of a four-week (one hour perweek) sleep improvement intervention plus use of an aroma-necklace, was developed based on Cox’s Interaction Model of Client Health Behavior. 70 elderly women were assigned to the experimental (n=35) or control group with no intervention (n=35). Data from 62 participants (32 inthe experimental and 30 in the control) were analyzed using the SPSS 21.0 program. Women in the experimental group were instructed to constantlywear the aroma necklace filled with marjoram and orange oil until the program was completed. Sleep quality, sleep duration, sleep satisfaction,depression, anxiety, and blood pressure were measured to identify the effectiveness of the program. Results: Significant group differenceswere found in sleep quality (t=-5.10, pqqqlt;.001), sleep duration (z=-3.10, p=.002), sleep satisfaction (z=-4.13, p=qqqlt;.001), depression (t=2.53,p=.015), and anxiety (z=-2.47, p=.014). No differences were found in the systolic or diastolic blood pressure. Conclusion: The results indicatethat a sleep improvement program combined with an aroma-necklace was effective in improving sleep disturbances in elderly women living athome. Nurses may contribute to improving sleep among elderly women by applying this program to aged women living in various environments.
