A Quasi Experimental Study To Assess The Effectiveness Of Aroma Therapy (Lavender Oil) On Quality Of Sleep Among Elderly People (≥60 Years) Residing At Selected Old Age Homes Of District Mandi (H.P.)

Abstract

Sleep disturbances are common among older adults and may adversely affect physical, cognitive, and emotional well-being. Lavender oil aromatherapy is a simple, non-pharmacological approach that may promote better sleep. To assess the effectiveness of lavender oil aromatherapy on quality of sleep among elderly people (≥60 years) residing in selected old age homes of District Mandi, Himachal Pradesh. A quasi-experimental, non-randomized pre-test post-test control group design was used among 40 elderly people selected through non-probability purposive sampling. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The experimental group received lavender oil aromatherapy for 14 consecutive nights, while the control group received routine care. Data were analyzed using descriptive statistics, paired t-test, unpaired t-test, and chi-square test. The experimental group showed a reduction in mean PSQI score from 9.95 ± 2.724 at pre-test to 6.15 ± 2.889 at post-test (t = 9.628, p < 0.001), whereas no significant change was observed in the control group (t = 0.326, p = 0.748). The post-test comparison between groups was highly significant (t = −4.161, p < 0.001). In the control group, monthly income and primary source of financial support were significantly associated with post-test sleep quality (p = 0.034). Lavender oil aromatherapy was effective in improving sleep quality among elderly people residing in selected old age homes.
