台灣失智症者多,其中93.8%的輕度或中度之失智者生活在社區,主要照顧者遭受許多生理、心理及社會等壓力,產生憂鬱及降低睡眠品質,因此,本研究欲探討放鬆技巧介入於輕、中度失智症病人之主要照顧者憂鬱情緒與睡眠品質的成效。主要照顧者以隨機分配至實驗組及對照組,每組12位,實驗組接受為期八週,共計八次之放鬆技巧;對照組接受三次之一般常規衛教。運用貝氏憂鬱量表(Beck Depression Inventory II, BDI-II)及匹茲堡睡眠品質量表(Pittsburgh Sleep Quality Index, PSQI)於第一週、第四及第八週進行憂鬱及睡眠品質之測量。以廣義估計方程式進行統計分析,結果發現放鬆技巧介入後,實驗組之憂鬱分數較對照組為低,於第四週(β=-1.00,p=0.11)、第八週(β=-1.2,p<0.05)之憂鬱分數較第一週為低,且組別與時間的交互作用項第八週(β=-3.97,p<0.05)達統計顯著差異;實驗組之睡眠品質改善分數較對照組為多,但未達統計差異;但組別與時間的交互作用項於第四週(β=-1.84,p<0.05)和第八週(β=-4.26,p<0.05)皆達統計顯著差異。本研究顯示放鬆技巧介入的時間愈長,憂鬱狀況愈改善,且睡眠品質亦較佳。
There are a substantial amount of dementia patients in Taiwan and 93.8% of those with mild or moderate dementia patients live in the community. The caregivers for dementia patients experienced physical, psychological and social stress, leading to depression and reduction in quality of sleep. This study aimed to explore the effects of relaxation intervention on depression and quality of sleep among caregivers of those mild and moderate dementia patients. The caregivers were randomly assigned to the experimental group and the control group, with 12 in each group. The experimental group received relaxation intervention for eight weeks; a total of eight times; the control group received three routine health educations. Using the Beck Depression Inventory II (BDI-II) and the Pittsburgh Sleep Quality Index (PSQI) to measure depression and quality of sleep in the first week, the fourth week and the eighth week. Generalized estimating equations were used to analyze. The results showed that after the relaxation intervention, The depression scores of the experimental group were lower than those of the control group. Compared to the first week, the depression scores in the fourth week (β = -1.00, p = 0.11) and eighth week (β = -1.2, p < 0.05) were lower, with the interaction term between group and time reaching statistical significance in the eighth week (β = -4.26, p < 0.05). The sleep quality improvement score of the experimental group was better than that of the control group, although the difference was not statistically significant. However, the interaction term between group and time reached statistical significance in both the fourth week (β = -1.84, p < 0.05) and eighth week (β = -3.97, p < 0.05). This study showed that the longer the relaxation intervention, the better outcome on the depression and quality of sleep.
