Abstract
Reliable and stable environmental audit instruments are needed to successfully identify the physical and social attributes that may influence physical activity. This study described the reliability and stability of the PIN3 environmental audit instrument in both urban and rural neighborhoods. Four randomly sampled road segments in and around a one-quarter mile buffer of participants' residences from the Pregnancy, Infection, and Nutrition (PIN3) study were rated twice, approximately 2 weeks apart. One year later, 253 of the year 1 sampled roads were re-audited. The instrument included 43 measures that resulted in 73 item scores for calculation of percent overall agreement, kappa statistics, and log-linear models. For same-day reliability, 81% of items had moderate to outstanding kappa statistics (kappas ≥ 0.4). Two-week reliability was slightly lower, with 77% of items having moderate to outstanding agreement using kappa statistics. One-year stability had 68% of items showing moderate to outstanding agreement using kappa statistics. The reliability of the audit measures was largely consistent when comparing urban to rural locations, with only 8% of items exhibiting significant differences (α < 0.05) by urbanicity. The PIN3 instrument is a reliable and stable audit tool for studies assessing neighborhood attributes in urban and rural environments.

Comparing objective measures of the built environment in their associations with youth physical activity and sedentary behavior across heterogeneous geographies. Health Place 2017; 49:30-38.

Abstract
We compared two strategies for measuring built environment features in their associations with youth physical activity and sedentary behavior across heterogeneous geographies of Pennsylvania. Physical activity environments of communities representing a rural-to-urban gradient were characterized through direct observation and spatially referenced archival data subjected to confirmatory factor analysis. Stratified regression analyses assessed associations between environmental measures and behavioral outcomes by community type. Neither strategy was consistently associated with behavior across communities. Findings highlight the importance of differentiating community type in evaluating associations of the built environment, and the challenge of measuring meaningful differences that influence youth behavior across heterogeneous geographies.
