需要可靠和稳定的环境审计工具，以成功确定可能影响身体活动的身体和社会属性。本研究描述了PIN3环境审计工具在城市和农村社区的可靠性和稳定性。在怀孕、感染和营养(PIN3)研究中，在参与者住所四分之一英里的缓冲区内及其周围的四个随机抽样的路段被评为两次，大约相隔两周。一年后，对第一年抽样道路中的253条进行了重新审计。该工具包括43项测量，产生73个条目分数，用于计算总体一致性百分比、kappa统计和对数线性模型。在同一天的信度方面，81%的条目具有中等到显著的Kappa统计(Kappas≥ 0.4.4)。两周的信度略低，根据kappa统计，77%的条目具有中等到显著的一致性。使用kappa统计，一年稳定性有68%的项目显示出中等到显著的一致性。在比较城市和农村地区时，审计措施的可靠性基本一致，只有8%的项目显示出按都市性划分的显著差异(α<； 0.05)。PIN3是一种可靠而稳定的审计工具，用于研究评估城乡环境中的社区属性。
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.
