Subthreshold depression represents a state of psychological sub-health between normal individuals and clinical depression. It constitutes a high-risk stage for developing clinical depression and a critical phase for alleviating depressive symptoms. However, current research predominantly focuses on treating depression in the elderly, with insufficient attention to interventions for high-risk populations or limited to cross-sectional investigations of subthreshold depression risk factors. Therefore, prioritizing subthreshold depression in the elderly and implementing early interventions is essential. A 2024 article in The Lancet suggests that subthreshold depression treatment should prioritize psychotherapy and lifestyle adjustments over medication. Horticultural therapy, an interdisciplinary approach integrating horticulture, medicine, and psychology, demonstrates unique advantages over traditional medical treatments. In practical application, however, limited resources may hinder adequate support for horticultural activities, compromising activity quality, reducing therapeutic efficacy, and restricting the widespread adoption of horticultural therapy. Integrating VR technology with horticultural therapy can provide patients with more comprehensive, personalized, and effective mental health treatment plans, empowering them toward healthier, more positive lives. Therefore, the research team designed a VR horticultural intervention system for elderly individuals with subthreshold depression based on the Social Participation Competence Framework.
