Brief summary

General Formulation Are there any changes in the inflammatory pathway and psychotic conditions in patients given Forest Therapy compared to conventional psychotic disorder therapy? Specific Are there any differences in the levels of inflammatory factors such as CRP, IL-6, and BDNF in patients given Forest Therapy compared to conventional psychotic disorder therapy? Are there differences in the psychotic conditions of patients, as assessed by PANSS, MADRSS, DASS-21, YMRS, Zung Anxiety Self Questionnaire, PSQI, and WHO-QL BREF, in patients receiving Forest Therapy compared to conventional psychotic disorder therapy? 1.3 Research Objectives 1.3.1 General Objective To determine the changes that occur in the inflammatory pathway and psychotic condition in patients receiving Forest Therapy compared to conventional psychotic disorder therapy. 1.3.2 Specific Objective To determine changes in the inflammatory pathway, particularly CRP, IL-6, and BDNF, in patients receiving Forest Therapy compared to conventional psychotic disorder therapy. To determine changes in psychotic conditions using the PANSS, BDI, MADRS, DASS-21, YMRS, Zung Anxiety Self Questionnaire, PSQI, and WHO-QL-BREF questionnaires in patients receiving Forest Therapy compared to conventional psychotic disorder therapy. To investigate the relationship between changes in inflammatory pathways and changes in psychotic conditions in patients receiving Forest Therapy compared to conventional psychotic disorder therapy. The research group will be divided into two groups using randomisation. The treatment group will receive forest therapy in the Mangkang forest from June to September 2025, with one session every two weeks for a total of eight sessions, while the control group will receive treatment for psychotic disorders as usual. Both groups will undergo psychometric testing, which includes assessment of psychotic symptoms, mood, insomnia, anxiety, stress levels, and quality of life. Blood samples will also be collected for complete blood count and inflammatory factor testing.

Detailed description

Intervention (8 sessions of 8 mg) Forest therapy will be provided in the form of mindful walking, forest bathing, mindful eating, meditation, and tree hugging.

Masking description

Each patient was assigned an identification number, and the researcher who drew blood did not know whether the patient was in the treatment group or the control group

Intervention model description

The treatment group will receive forest therapy in the Mangkang forest from June to September 2025, with a frequency of once every two weeks for 8 sessions, while the control group will undergo psychotic disorder therapy as usual. Both groups will undergo psychometric testing, including assessment of psychotic symptoms, mood, insomnia, anxiety, stress levels, and quality of life.
