More walkable neighborhoods are linked to increased physical activity. The Walking Suitability Index of the territory (T-WSI) is an easy method to evaluate walkability on the basis of direct observation. T-WSI provides 12 indicators divided into 4 categories (practicability, safety, urbanity, pleasantness); the weighted analysis of these indicators gives an overall score of the actual usability of the neighborhood. The aim of the study is to evaluate the ability of T-WSI' indicators to measure, in a reliable way, any street's walkability variations occurred over time. The investigation was performed in 2018 in nine urban neighborhoods of Rieti city. Cronbach's α is used to evaluate internal consistency of T-WSI; Intraclass Correlation Coefficient (ICC) is used to evaluate the reproducibility of measurements (or ratings) made by different investigators. Cronbach's α is 0.89 (± 0.02); ICC is also good (ICC = 0.89; 95% CI: 0.84-0.92). The results of the 2018 investigation are also compared with those collected in 2016 in the same districts. The results show that T-WSI is a reliable and easy to use tool, useful to measure the effectiveness of the interventions already realized at local level, but it could also contribute to making decisions to develop regeneration projects.
更适合步行的社区与更高的身体活动水平相关。该地区的步行适宜性指数（T-WSI）是一种基于直接观察评估步行适宜性的简单方法。T-WSI 提供了 12 个指标，分为 4 类（实用性、安全性、城市性、舒适性）；对这些指标进行加权分析，可得出社区实际可用性的综合得分。本研究旨在评估 T-WSI 指标能够可靠测量任何街道随时间推移的步行适宜性变化的能力。该调查于 2018 年在里耶蒂市的 9 个城市社区进行。克朗巴赫 α 用于评估 T-WSI 的内部一致性；组内相关系数（ICC）用于评估不同研究者进行的测量（或评分）的可重复性。T-WSI 的克朗巴赫 α 为 0.89（±0.02）；ICC 也很好（ICC=0.89；95%CI：0.84-0.92）。2018 年的调查结果还与同年在同一地区收集的 2016 年的结果进行了比较。结果表明，T-WSI 是一种可靠且易于使用的工具，可用于测量已经在地方层面实施的干预措施的有效性，但它也有助于做出发展再生项目的决策。
