A Study on the Intervention Effect of Therapeutic Horticulture Based on the Healing System on Non-suicidal Self-injury in Adolescent Patients With Depression

Non-suicidal self-harm is a serious issue. Adolescents with depression are among the high-risk groups for non-suicidal self-harm behavior. Therapeutic gardening uses plant cultivation and corresponding gardening activities as the medium of action, allowing patients to obtain therapeutic benefits by participating in gardening activities such as planting, maintaining, and harvesting plants. Therefore, this study will apply therapeutic gardening based on the healing system to adolescents with depression who have non-suicidal self-harm behavior, in order to improve their non-suicidal self-harm behavior, negative emotions, emotional expression disorders, self-efficacy, sleep quality, and loneliness.

Based on the theories of positive psychology and the healing system theory framework, referring to relevant domestic and foreign literature and consulting books such as "Introduction to Horticultural Therapy", "Horticultural Rehabilitation Therapy Techniques", and "Horticultural Therapy: Growing Good Health for the Body and Mind", an intervention plan was formulated under the guidance of experts. A randomized controlled trial design was adopted. It is planned to carry out therapeutic horticulture based on the healing system for adolescent patients with depression who have non-suicidal self-harming behaviors, according to the intervention plan. By evaluating and comparing the changes and differences in indicators such as non-suicidal self-harming behaviors, emotions, physical functions, skills, and social interaction of the experimental group and the control group before and after the intervention, the actual effect of therapeutic horticulture based on the healing system in reducing the occurrence of non-suicidal self-harming behaviors among adolescent patients was verified. Finally, data analysis and paper writing were conducted.
