Generalized Anxiety Disorder (GAD) is a mental illness that causes mental pain and disease burden comparable to depression, and has a significant impact on patients’ social functions and life quality. Therefore, the Diagnostic and Statistical Manual of Mental Disorders in the United States regards “difficulty in maintaining attention” as one of the diagnostic criteria for GAD. This study used horticultural landscape therapy combined with group mindfulness intervention to intervene in anxiety disorders among spatial design students.

This experiment targeted 140 students with anxiety disorders and randomly divided them into two groups. The control group composed of 70 people and used traditional mindfulness intervention therapy, while the experimental group used horticultural landscape therapy combined with group mindfulness intervention to intervene in anxiety disorders of spatial design students. This experiment was measured using the Hamilton Anxiety Scale.

The results showed that at the end of the 8-week treatment, the Hamilton Anxiety Scale scores of both groups decreased compared to baseline, while the pre-intervention scores of both groups increased compared to baseline. The efficacy of the Milton Anxiety Scale in the experimental group was higher than that in the control group, and the clinical curing rate was also higher in the experimental group than in the control group.

Horticultural landscape therapy combined with group mindfulness intervention can effectively alleviate anxiety symptoms and improve attention maintenance function in patients with generalized anxiety disorder in spatial design students.
