Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • The level and frequency of non-suicidal self-injury

    The adolescent self-harm questionnaire was used to measure.This questionnaire is a self-assessment form, consisting of 19 items. Among them, the frequency of non-suicidal self-injury behavior is scored using the Likert 4-point scale: "0 times" is scored 0 points, "1 time" is scored 1 point, "2-4 times" is scored 2 points, and "5 times or more" is scored 3 points. The degree of physical harm caused is scored using the Likert 5-point scale: "No" is scored 0 points, "Mild" is scored 1 point, "Moderate" is scored 2 points, "Severe" is scored 3 points, and "Extremely severe" is scored 4 points. NSSI equivalence is equal to the product of the NSSI frequency score and the NSSI severity score. The higher the score, the more severe the condition.
