TABLE 1.

Topic list.

1. General questions
• How often have you had therapy sessions while walking outside in nature?
		∘ And how often have you had therapy sessions indoors?
• How did you get to the decision to choose a treatment where you would receive therapy while walking outside in nature?
		∘ Or, if your therapist suggested this context for treatment, what did you think of this suggestion?
		∘ What did you expect of the sessions in nature beforehand?
• How does/did your therapist incorporate nature in the sessions?
2. Suggestions for questions during the Imagination
Please close your eyes or look at a neutral point in front of you. Just take a few deep breaths in and out…… Try to imagine again that you are in a session, walking alongside your therapist outside in nature. Do you see it in front of you again?
• What do you see/hear/smell?
• What is happening?
• What are you discussing?
• What are you doing?
• What role does nature play in this experience?
• What is going on inside of you?
• How do you feel/how does that feel?
• How do you notice that?
• What do you feel in your body?
• What does this do with you?
• What about nature makes it so?
• What about that moves you?
• What does that mean for you (as a person)?
3. Follow-up discussion after the imagination
• To what extent was what you just experienced about the role of nature something typical of any session outside?
		∘ To what extent do you think the element of nature influences what you get out of therapy?
• What would be different if this session had not happened in nature, but inside a consulting room?

The underlined questions were the central questions which gave most insight into the inner world experiences of clients.
