Neighborhood observation, whereby trained observers systematically document well-defined aspects of neighborhood environments, is an increasingly popular method to identify mechanisms by which living in impoverished neighborhoods negatively impacts health. In this presentation, we provide an overview of the content of the Neighborhood Observational Checklist (NOC), a tool we used to assess aspects of the physical, built, and social environments of neighborhoods. It was developed using a community-based participatory research process by the Healthy Environments Partnership. We describe strategies employed to train residents to collect data with the NOC. The observer training strategies included the following: instruction on operational definitions including use of photographs to illustrate items and rating scale categories, instruction on handheld computers for data collection, group and individual practice sessions, group discussions around NOC content and community sensitivity during data collection, feedback of interrater reliability (IRR) results based on performance on practice blocks to observers including individualized feedback, and certification of observers based on individual IRR results. We then share reliability results from data collected on 550 blocks in Detroit. We evaluated IRR in two ways: for blocks across twelve observers, including the gold standard, using a Kappa statistic proposed by Gwet (2002) and for street segments rated by two different observers using Cohen’s Kappa statistic. Test-retest reliability was evaluated for street segments rated by the same observer when observing adjacent blocks at different time points using Cohen’s Kappa statistic. Finally, we offer suggestions for future research and discuss implications for community health planning efforts using neighborhood observation.
