Table 3 Agreement between the individual-level self-assessed (< 5-10 min walking distance) and objectively assessed availability (< 100, 300 and 500 meters distance from residence) of the five green qualities, Culture, Lush, Serene, Spacious and Wild. Agreement is given as sensitivity and specificity (%), separately and as a sum.

^a Sensitivity was defined as the proportion of "true" positive self-assessment and the specificity as the "true" negative self-assessment, using the objective assessments based on GIS as gold standard. Missing self-assessments and don't know scores were excluded.
