Effects of Forest Therapy on Physical and Psychological Parameters in the General Population

In recent years, nature and forest therapy has increasingly become the focus of medical research. Recent scientific findings indicate overall positive effects of nature and forest therapy on physical and mental health. In Asia and Australia, it has already been implemented as a public health concept of prevention and health promotion. The aim of the project is to replicate the experience gained in Asia over the last three decades on the physical and psychological effects of nature/forest therapy in the context of the German forest and to investigate it further scientifically.

Primary outcomes

  1. Profile of Mood States (POMS)

    Time frame: Change from baseline POMS score at 3 days

    Assessing full scale, range 1-7, lower score meaning a better outcome

Secondary outcomes

  1. Perceived Benefits of Nature Questionnaire (PBNQ)

    Time frame: Change from baseline PBNQ score at 3 days

    Assessing full scale, range 1-7, lower score meaning a better outcome

  2. Subjective Vitality Scale state (SVS-G state)

    Time frame: Change from baseline SVS-G score at 3 days

    Assessing full scale, range 1-80, higher score meaning a better outcome

  3. Complaint List (B-LR)

    Time frame: Change from baseline B-LR score at 3 days

    Assessing full scale, range 1-50, lower score meaning a better outcome

  4. Perceive Stress Questionaire (PSQ)

    Time frame: Change from baseline PSQ score at 3 days

    Assessing full scale, range 1-40, lower score meaning a better outcome

  5. State-Trait Anxiety Inventory (STAI)

    Time frame: Change from baseline STAI score at 3 days

    Assessing state anxiety. The scale ranges from 1 to 8. Higher scores correspond to higher levels of anxiety (after recoding three inverted items).

  6. PROMIS Scale v1.2 - Global Health

    Time frame: Change from baseline PROMIS score at 3 days

    The scale ranges from 1 to 5, where 1 is the lowest level and 5 is the highest level. Higher scores reflect better functioning.

  7. Allgemeine Selbstwirksamkeit Kurzskala (ASKU)

    Time frame: Change from baseline ASKU score at 3 days

    Assessing full scale, the scale ranges from 1 to 5. Higher scores correspond to better outcomes.
