Existing measures of perceptions of the environment associated with walking commonly rely on providing a definition of 'neighbourhood', e.g. 1 mile area around the home. We have little understanding of how these examples relate with adults' own geographical definitions of their neighbourhood area. Our pilot study examined the congruence between definitions used in environmental questionnaires and adults' own definitions of neighbourhood.
We conducted 58 face-to-face interviews with participants randomly selected from 10 areas of Stoke-on-Trent, England. Participants were shown printed maps showing their local area with road names and places of interest (e.g. shops, services, green space) and were asked: (i) to recall usual walking destinations (from their home); (ii) to draw their 'neighbourhood walking area' on the map. Annotated maps were scanned back into GIS for analysis.
When asked to draw their 'neighbourhood' boundary, the resulting area drawn by participants on average represented only 16 +/- 20% of the commonly used total straight-line buffer of 1 mile (or 1.6 km) with a range of 0.3% to 111%. Even when repeated using a network buffer (rather than straight-line) the same comparison resulted in a mean of 36% (+/- 47%) and a range of 0.6 to 245%.
We found that adults' interpretation of their neighbourhood area does not appear to relate accurately to the definitions typically used in research into environmental perceptions and walking. This mis-match warrants further investigation as definitions used in existing measures may be consistently misclassifying perceived local walking neighbourhoods.
现有的与步行相关的环境感知测量方法通常依赖于提供“邻里”的定义,例如,住所周围 1 英里的区域。我们对这些示例如何与成年人自己对邻里区域的地理定义相关知之甚少。我们的初步研究考察了环境问卷中使用的定义与成年人自己对邻里的定义之间的一致性。
我们在英格兰斯托克市的 10 个地区随机选择参与者进行了 58 次面对面访谈。参与者展示了印有他们当地道路名称和感兴趣地点(如商店、服务、绿地)的地图,并被问到:(i)回忆他们通常从家出发的步行目的地;(ii)在地图上画出他们的“邻里步行区”。注释后的地图被扫描回 GIS 进行分析。
当被要求画出他们的“邻里”边界时,参与者平均画出的区域仅代表常用的 1 英里(或 1.6 公里)直线缓冲区的 16 +/- 20%,范围从 0.3%到 111%。即使使用网络缓冲区(而不是直线)重复此操作,相同的比较结果仍导致平均 36%(+/- 47%),范围为 0.6 到 245%。
我们发现,成年人对其邻里区域的解释似乎与研究环境感知和步行时通常使用的定义不准确相关。这种不匹配值得进一步调查,因为现有测量方法中使用的定义可能会持续错误地分类感知到的当地步行邻里。
