Frail nursing home residents face multiple health challenges as a result of their frail status. The aim of this study was to examine the effects of HT on the psychosocial well-being of frail and prefrail nursing home residents.
Randomized controlled trial.
Nursing homes.
One hundred eleven participants were randomly allocated into the intervention [horticultural therapy (HT)] and control (social activities) conditions.
HT group participants attended a weekly 60-minute session for 8 consecutive weeks. Control group activities were social in nature, without any horticulture components.
The outcome measures include happiness, depressive symptoms, self-efficacy, well-being, social network, and social engagement. The time points of measurement were at baseline (T), immediately postintervention (T), and 12 weeks postintervention (T). A modified intention-to-treat approach was adopted. A multivariate general estimating equation was used to analyze the data.
Forty-six and 50 participants received at least 1 session of the intervention and control condition protocol, respectively. A significant interaction effect between group and time was observed only on the happiness scale (β = 1.457, P = .036), but not on other outcome variables. In a follow-up cluster analysis of those who received HT, a greater effect on subjective happiness (mean difference = 6.23, P < .001) was observed for participants who were happier at baseline.
HT was found to be effective in promoting subjective happiness for frail and prefrail nursing home residents. Its favorable effect suggests that HT should be used to promote the psychosocial well-being of those who are frail.
虚弱的养老院居民由于其虚弱状态而面临多种健康挑战。本研究旨在探讨 HT 对虚弱和轻度虚弱的养老院居民的社会心理福祉的影响。
随机对照试验。
养老院。
111 名参与者被随机分配到干预组（园艺治疗 [HT]）和对照组（社交活动）。
HT 组参与者每周参加一次 60 分钟的课程，共 8 周。对照组的活动性质是社交活动，没有任何园艺成分。
结果测量包括幸福感、抑郁症状、自我效能、幸福感、社交网络和社交参与度。测量时间点为基线（T）、干预后即刻（T）和干预后 12 周（T）。采用修改后的意向治疗方法。采用多变量一般估计方程分析数据。
分别有 46 名和 50 名参与者接受了至少 1 次干预和对照组方案的治疗。仅在幸福感量表上观察到组间和时间的显著交互效应（β=1.457，P=.036），而其他结果变量则没有。在对接受 HT 的参与者进行的后续聚类分析中，对于基线时幸福感较高的参与者，HT 对主观幸福感的影响更大（平均差异=6.23，P<.001）。
HT 被发现对虚弱和轻度虚弱的养老院居民的主观幸福感有效。其有利影响表明，HT 应被用于促进那些虚弱的人的社会心理福祉。
