Sixty adult patients from private hospitals in Dumaguete Citywere randomly assigned to two groups, the experimental group (n=30)would receivearomatherapy using lavender essential oil with standard nursing care placebo group(n=30)would receive aromatherapy using distilled water with standard nursing care.The researcher utilized Richard-Campbell Sleep Questionnaire, a 5-item 100-mmvisual analogue scale to measure five domains of sleep: sleep latency, sleep efficiency,sleep depth,awakenings, and sleep quality; the final score represents how well theparticipant has slept.
