Three measures of nature experiences used in this study; we used the resultant variables as predictor variables in our analysis.

Measure	Question	Answer scale

Duration of greenspace (“more immediate” experience)	During the last month (i.e., May), how much time did you spend in neighborhood greenspace on an average week?	no time; less than 1 h; 1–2 h; 2–4 h; 4–6 h; 6–8 h; 8–10 h; 10–12 h; over 12 h†
Green view through windows from home (“less immediate” experience)	In your house do you have a green view from the room in which you spend most of your time at home?‡	green view, no green view

^†For analysis we converted to a continuous variable: (0, 0.5, 1.5, 3, 5, 7, 9, 11, 12).

^‡Green views included roadside trees, garden trees, parks, woodlands.
