Assessing the feasibility of public engagement in a smartphone app to improve well-being through nature connection

Aside from practical interventions such as providing green infrastructure to improve air quality or water contamination and reduce flooding, well-being interventions to increase engagement with the natural environment are one of the fastest growing ways of improving human and environmental health. This feasibility study assessed a novel smartphone app for well-being intervention. Over 30 days the app prompted adults, including those seeking help for a common mental health problem, to notice the good things about urban green or built spaces (control condition). Self-referral was successful with 885 people downloading the app, 435 supplying baseline data and 50 supplying post-intervention data. However, the low number of observations (M = 6 per participant) indicates that 30 days is too long to remain engaged. There were significant improvements in well-being and nature connection, but no difference between green and built space conditions. Limitations, future recommendations regarding improving engagement and marketing to lower socio-economic status groups are discussed.
