Alcohol outlet density and alcohol-related harms are an internationally reported phenomenon. There are multiple methods described in the literature to measure alcohol outlet density, but with very little commentary on the geographical underpinnings of the methods. In this paper, we present a framework to help practitioners and researchers choose the most appropriate spatial method of measuring alcohol outlet density. The framework includes components on theoretical geography, statistical implications and practical considerations, with an emphasis on population-level exposure. We describe the CHALICE alcohol outlet density measurement method that was developed to investigate the relationships between alcohol outlet density and population harm. The CHALICE method is compared to four other methods found in the published literature. We demonstrate the impact of methodological choices (e.g. network vs. Euclidean distances) on resulting alcohol outlet density scores. We conclude that wherever possible the best practice approach to modelling alcohol outlet density should be used to facilitate flexibility in subsequent statistical analysis and improve the transparency of the results.

衡量酒精供应空间变化的最佳实践框架

酒精出口密度和酒精相关危害是国际上报道的现象。文献中描述了多种方法来测量酒精出口密度，但对这些方法的地理基础几乎没有评论。在本文中，我们提出了一个框架来帮助从业者和研究人员选择最合适的空间方法来测量酒精出口密度。该框架包括理论地理、统计意义和实际考虑的组成部分，重点是人口水平的暴露。我们描述了 CHALICE 酒精出口密度测量方法，该方法旨在调查酒精出口密度与人口危害之间的关系。CHALICE 方法与已发表文献中的其他四种方法进行了比较。我们展示了方法选择（例如网络与欧几里得距离）对由此产生的酒精出口密度分数的影响。我们得出的结论是，应尽可能使用模拟酒精出口密度的最佳实践方法，以促进后续统计分析的灵活性并提高结果的透明度。
