研究背景：隨著全世界人口高齡化，失智症患者的數量也隨之提升，尤其長者是失智症的高風險族群，且憂鬱為失智症患者的普遍症狀，連帶影響到睡眠品質，而芳香療法相較於藥物較不會引起副作用，是當今改善失智症患者生活品質的趨勢。
研究目的：探討嗅吸靜謐複方精油對於長照機構失智症長者憂鬱情緒及睡眠品質之成效。
研究方法：於台灣南部兩家長照機構進行立意取樣，收案36位，所有個案於一開始收案時先確認二週內無使用精油後，即進行第1次前測(T0)，之後第1週及第2週為精油介入期，精油介入方式為於賞香儀置入靜謐複方精油並執行空間精油擴散，1天2次，連續介入2週，1週5天，並於第1週結束進行第1次後測(T1)、第2週結束進行第2次後測(T2)，第3週及第4週停止介入精油，並於第4週結束進行追蹤後測(T3)，前後測皆以康乃爾失智者憂鬱量表及匹茲堡睡眠量表進行介入前後評估。以一般線性模式之單組重複測量(General linear model repeated measurement, GLM )進行比較介入成效的差異。
研究結果：本研究結果顯示失智症長者接受靜謐複方精油芳香療法介入後，和前測(T0)相比，憂鬱方面整體狀況及其次面向「行為障礙」、「生理徵兆」在第一次後測(T1)及第二次後測(T2)皆達到顯著差異(p＜.05)，「與情緒相關之徵兆」、「週期性功能」、「觀念障礙」在每次測量點下則皆未達到顯著差異(p＜.05)；睡眠品質方面，在每次測量點，不論是整體或所有次面向皆未達到顯著差異(p＜.05)。
研究結論：根據本研究結果，使用靜謐複方精油可能改善失智症長者的整體憂鬱情緒，或是「行為障礙」、「生理徵兆」之層面，建議未來可以隨機對照試驗來驗證其效果。期盼未來芳香療法能在台灣醫療場域更廣泛應用，改善其生活品質並減輕照顧者的負擔壓力。

Background: With the aging of the world's population, the number of patients with demen-tia is increasing, especially the elderly are a high-risk group for dementia. Depression is a common symptom among dementia patients, which affects the quality of sleep. Aromathera-py, which causes less side effects than drugs, is a current trend to improve the quality of life of dementia patients.
Purpose: To explore the effects of Pampering essential oil on and depression and sleep quality of elderly people with dementia residing in long-term care institutions.
Method:A purposive sampling was conducted in two long-term care facilities in southern Taiwan, resulting in a final enrollment of 36 participants. All cases were confirmed to have not used essential oils within two weeks prior to the initial enrollment. The first pretest (T0) was conducted at the beginning of the enrollment process. Subsequently, the intervention involving essential oils was carried out during the first and second weeks. The intervention method included placing Pampering essential oil into an aromatic diffuser in the designated space, administered twice a day for two consecutive weeks, five days a week. The first post-test (T1) was conducted at the end of the first week, and the second post-test (T2) was con-ducted at the end of the second week. The intervention with essential oils was halted during the third and fourth weeks. The follow-up post-test (T3) was conducted at the end of the fourth week. Both pre- and post-tests involved assessments using the Cornell Scale for De-pression in Dementia (CSDD) and the Pittsburgh Sleep Quality Index (PSQI). General linear modeling using the repeated measures design (GLM repeated measurement) was employed to compare the differences in intervention effectiveness.
Results: The results of this study showed that after an intervention using Pampering essential oils, elderly people with dementia had better health outcomes at the first post-test (T1) and the second post-test (T2) compared with the pre-test (T0) ( p< .05).However, "emotion-related signs", "circulatory function" and "conceptual disturbance" did not show significant differences at each measurement point (p< .05).Regarding sleep quality, neither overall nor any specific aspect showed significant differences at any measurement point (p< .05).
Conclusion: The use of Pampering essential can improve the overall depressive mood in de-mentia patients, especially in the dimensions of "behavioral disturbance" and "physical signs" . Recommendations for future validation through randomized controlled trials to verify its effectiveness. Hopeful for the wider application of aromatherapy in the healthcare field in Taiwan, aiming to improve their quality of life and alleviate the burden of caregivers.
