Measuring the built environment: validity of a site survey instrument for use in urban settings.
There are few reliable measures of place with which to study the effects of socio-economic context on health. We report on the development and inter-rater reliability of a 27-item observer-rated built environment site survey checklist (BESSC). Across eleven 'housing areas' (defined as areas of homogeneity in housing form) and two raters, kappa coefficients were > or =0.5 for fifteen categorical items, and intra-class correlation coefficients exceeded 0.6 for a further three continuous measures. Ratings on several BESSC items were associated to a statistically significant degree with the prevalence of depression and residents' dissatisfaction with 'their area as a place to live'. BESSC items may prove to be valuable descriptors of the urban built environment in future studies.
