本研究旨在探討園藝輔療對高齡者的介入成效，以南投某社區關懷據點20位高齡者為研究對象，參與者年齡介於71至94歲之間。這些長者大多患有多重慢性疾病，包括高血壓、糖尿病、帕金森氏症、輕度失智等症狀。研究採用衛生福利部預防及延緩失能照護計畫之園藝方案，進行為期12週的介入，每週一次，每次2小時。課程內容包含手作及園藝活動，著重於訓練上肢活動能力、增進自信心、培養自主權及促進社交互動。評估工具採用ICOPE長者功能自評量表、簡易身體表現功能量表及簡易智能狀態測驗進行前後測比較。研究結果顯示，參與者在三個主要面向均呈現顯著進步：憂鬱情緒從2.80分降至2.04分、身體功能從2.85分降至2.50分、認知功能從3.15分降至2.35分。課程滿意度也從「滿意」提升至「非常滿意」。研究發現園藝輔療透過植物栽種、園藝創作等活動，能有效促進高齡者的感官刺激及學習，帶來正向的情緒變化。然而，研究限制包括收案樣本數較少，難以推論至其他區域及年齡層。建議未來研究可擴大研究範圍，並進一步探討不同類型園藝活動對不同失能程度高齡者的影響。

This study aims to investigate the effectiveness of horticultural therapy intervention for the elderly at a community care station in Nantou, with 20 elderly participants aged between 71 and 94 years. Most of these elderly individuals have multiple chronic conditions, including hypertension, diabetes, Parkinson’s disease, and mild dementia. The study adopted the horticultural program from the Ministry of Health and Welfare’s Prevention and Disability Delay Care Plan, implementing a 12-week intervention with weekly 2-hour sessions. The course content included handicrafts and horticultural activities, focusing on training upper limb mobility, enhancing self-confidence, cultivating autonomy, and promoting social interaction. Assessment tools included the ICOPE Elderly Functional Assessment Scale, Short Physical Performance Battery, and Mini-Mental State Examination for pre- and post-intervention comparisons. Research results showed significant improvements in three main aspects: depressive mood decreased from 2.80 to 2.04, physical function improved from 2.85 to 2.50, and cognitive function enhanced from 3.15 to 2.35. Course satisfaction also increased from “satisfied” to “very satisfied.” The research found that horticultural therapy, through plant cultivation and horticultural creative activities, effectively promoted sensory stimulation and learning in the elderly, leading to positive emotional changes. However, research limitations included a small sample size, making it difficult to generalize findings to other regions and age groups. Future research suggestions include expanding the research scope and further exploring the effects of different types of horticultural activities on elderly individuals with varying degrees of disability.
