A Systematic Review of Horticultural Therapy’s Influence on Chinese Older Adults’ Psychosocial Wellbeing

Aim: This systematic review aims to evaluate changes in Chinese older adults’ psychosocial wellbeing after receiving horticultural therapy, and examine existing evidence regarding horticultural therapy’s effectiveness in a Chinese setting. Method: Intervention studies measuring relevant outcomes amongst older adults and conducted in China were identified from ASSIA, CIHAHL Plus, PsycINFO, EMBASE, MEDLINE, SCOPUS, Web of Science Core Collection and CNKI. Cochrane risk of bias assessment tools were used to appraise study quality. Result: 16 studies were selected, among which four were published in English and 12 in Chinese. Findings suggested that after receiving horticultural therapy, older adults’ psychosocial wellbeing is generally improved, but causal relationships between improvements and horticulture therapy were less clear. Conclusion: Features of horticultural therapy conducted in China is with its cultural and social uniqueness. Existing evidence supports the post-intervention benefits on completion of horticultural therapies, but the limitations in programme design, sample representativeness and methodological robustness limited the quality of the evidence.
