基于可食地景的长期园艺疗法对失智老人生活质量的影响研究

A Preliminary Study on the Effect of Long-term Horticultural Therapy Based on Edible Landscape on Improving the Life Quality of the Elderly with Dementia

摘要:

园艺疗法已被证明在改善失智老人的行为障碍和精神症状方面有显著潜力，但多数研究的干预时间较短，疗效难以持久。为探究园艺疗法的长期效果和可食地景的恢复效益，开发了以可食地景为蓝本的长期高频度园艺疗法程序，选取 35 名长期居住于浙江省杭州市某医养结合机构的失智老人为研究对象，对其进行系统干预和追踪观察。研究发现：失智老人的认知能力在园艺疗法实施期间无显著衰退，行为障碍和激越行为发生频率均显著降低。可见长期实施可食地景园艺疗法显著改善了失智老人的生活质量、行为障碍和精神症状，对增强失智老人的自我效能感和社交互动能力有良好的效果，且疗效持续时间较长。
