PANES physical activity and neighborhood environment scale; NC non-calculable.
aFor PANES items related to walking and bicycling, respondents who answered this item “does not apply to my neighborhood” were not included in score distributions and were not counted in non-response totals; an alternative scoring strategy to preserve observations is described the Supplementary Methods.
bAlpha is non-calculable with 2 sub-items.
