The Influence of Green Space on Mental Health

The aim of this scoping review of reviews is to examine the evidence that exists about green space and mental health and provide a comprehensive scan of the vast amount of literature that exists in this area of study. [...] The indicators for the quantity of green space, as found through this scoping review of reviews, fall into three categories: the amount of green space (eight articles), the number of green spaces (two articles), and the perception of green space (two articles). [...] Indicators of Quality of Green Space associated with Mental Health and Well-being In the sub-analysis, there was a total of 28 indicators identified measuring the quality of green space. [...] One indicator of the quality of green space was found to have a negative association with mental health and well-being (objectively measured species richness) (see Table 5 in the Appendicies for a full list of indicators of quality of green space). [...] There are 29 factors that increase the influence of green space on mental health and well- being (such as race/ethnicity or contact with nature) and four factors that decrease the influence of green space on mental health and well-being (such as use of green space or the dose exposure to nature).
