This online study aims to explore the benefits of nature for mood and cognition in persons with and without Parkinson's disease. For the purpose of this survey, "natural environment" refers to places that primarily consist of natural elements, such as vegetation, water bodies, and landscapes. This includes greenspaces (such as parks, gardens, neighborhood streets lined with trees, forests, or nature reserves) bluespaces (such as next to beaches, lakes, rivers, ponds, or waterfronts), and desert regions, among others.

Detailed Description

To participate in this online study, you will need an email address, and a smartphone or laptop/desktop with internet access. If you are eligible to participate, you will be sent a link to an online survey (Qualtrics). We will ask questions about demographic and health information, followed by questions about exercise habits, exposure to natural environments (including greenspaces and bluespaces, among others), and questionnaires assessing mood, motivation, cognition, sleep, stress, quality of life, and related functions. The survey should take roughly 20-25 minutes to complete. This is an observational study only, and not an interventional study. Compensation: A $15 Amazon gift card will be offered to those who complete the survey all the way through with good effort.
