Introduction:
Associations between exposure to nature and positive mental health outcomes have been established. Although the Internet is a popular source of accessing mental health information, little is known about the readability of such online information. Thus, the goal of this study was to assess the readability of online information regarding the association between exposure to nature and mental health.
Methods:
A search of webpages was conducted using the following search terms: 'mental health and urban greening', 'stress and urban greening', 'mental health and nature', 'stress and nature', 'mental health and outdoors', and 'stress and outdoors'. Readability of the 255 webpages identified was determined by the Flesch-Kincaid Grade Level measure.
Results:
On average, webpage content was written at an 11th grade reading level (Flesch-Kincaid Grade Level mean=11.95, SD=2.68), and fewer than 2% of webpages met readability guidelines (i.e. ≤6th grade reading level).
Conclusions:
Most online content related to nature and mental health should be written at a more appropriate level for general audiences. Web content developers should prioritize adherence to readability guidelines.
