An online version of the Microscale Audit of Pedestrian Streetscapes (Abbreviated) tool was adapted to virtually audit built environment features supportive of physical activity. The current study assessed inter-rater reliability of MAPS Online between in-person raters and online raters unfamiliar with the regions.
In-person and online audits were conducted for a total of 120 quarter-mile routes (60 per site) in Phoenix, AZ and San Diego, CA. Routes in each city included 40 residential origins stratified by walkability and SES, and 20 commercial centers. In-person audits were conducted by raters residing in their region. Online audits were conducted by raters in the alternate location using Google Maps (Aerial and Street View) images. The MAPS Abbreviated Online tool consisted of four sections: overall route, street segments, crossings and cul-de-sacs. Items within each section were grouped into subscales, and inter-rater reliability (ICCs) was assessed for subscales at multiple levels of aggregation.
Online and in-person audits showed excellent agreement for overall positive microscale (ICC = 0.86, 95% CI [0.80, 0.90]) and grand scores (ICC = 0.93, 95% CI [0.89, 0.95]). Substantial to near-perfect agreement was found for 21 of 30 (70%) subscales, valence, and subsection scores, with ICCs ranging from 0.62, 95% CI [0.50, 0.72] to 0.95, 95% CI [0.93, 0.97]. Lowest agreement was found for the aesthetics and social characteristics scores, with ICCs ranging from 0.07, 95% CI [-0.12, 0.24] to 0.27, 95% CI [0.10, 0.43].
Results support use of the MAPS Abbreviated Online tool to reliably assess microscale neighborhood features that support physical activity and may be used by raters residing in different geographic regions and unfamiliar with the audit areas.
对行人街道景观的微观尺度审计（简称）工具的在线版本进行了改编，以便对支持身体活动的建筑环境特征进行虚拟审计。本研究评估了在不熟悉地区的在线评估者与现场评估者之间 MAPS Online 的内部评估者可靠性。
在亚利桑那州凤凰城和加利福尼亚州圣地亚哥共进行了 120 条四分之一英里的路线（每个地点 60 条）的现场和在线审计。每个城市的路线包括 40 个根据步行能力和 SES 划分的住宅起源，以及 20 个商业中心。现场审计由居住在其地区的评估者进行。在线审计由居住在另一个地点的评估者使用谷歌地图（航空和街景）图像进行。MAPS 缩写在线工具由四个部分组成：整体路线、街道段、交叉口和死胡同。每个部分内的项目分为子量表，并且在多个聚合级别评估了子量表的内部评估者可靠性（ICC）。
在线和现场审计在整体积极微观尺度（ICC=0.86，95%CI[0.80,0.90]）和总评分（ICC=0.93，95%CI[0.89,0.95]）方面显示出极好的一致性。21 个子量表中的 30 个（70%）、 valence 和子部分评分显示出实质性到近乎完美的一致性，ICC 范围从 0.62，95%CI[0.50,0.72]到 0.95，95%CI[0.93,0.97]。美学和社会特征评分的一致性最低，ICC 范围从 0.07，95%CI[-0.12,0.24]到 0.27，95%CI[0.10,0.43]。
结果支持使用 MAPS 缩写在线工具可靠地评估支持身体活动的微观邻里特征，并且可以由居住在不同地理区域且不熟悉审计区域的评估者使用。
