Adults experiencing homelessness (AEH) are more likely to engage in risky alcohol use compared to adults in the general population. Nonetheless, relatively little is known about the naturalistic settings of alcohol use among AEH. We integrate risk terrain modeling (RTM) with geographically-explicit ecological momentary assessments (GEMAs) to identify the environmental characteristics of drinking locations among AEH in Dallas, Texas. Participants were given a study-provided smartphone pre-installed with the Insight application and instructed to self-initiate a GEMA when they were about to consume their first drink of the day over the duration of four weeks. Participants who used this app feature to report alcohol use were included in the analytic sample ( = 22). RTMs estimated the spatial influence of environmental features associated with alcohol availability and risky community features located in the city limits of Dallas, as well as in downtown Dallas. Across the City-Wide and Central Division analyses, proximity to food banks/shelters and public libraries are spatially associated with event locations of AEH alcohol use. Clusters of liquor stores and grocery stores are also significantly related to alcohol event locations. Findings provide insight into the geographical context of alcohol use among AEH and have implications for researchers and practitioners.
与普通人群中的成年人相比，无家可归的成年人（AEH）更有可能从事危险饮酒行为。尽管如此，人们对AEH饮酒的自然环境了解相对较少。我们将风险地形建模（RTM）与地理明确的生态瞬时评估（GEMA）相结合，以确定德克萨斯州达拉斯市AEH饮酒场所的环境特征。研究为参与者提供了一部预先安装了Insight应用程序的智能手机，并指示他们在四周的时间内，当他们准备喝当天的第一杯酒时自行启动一次GEMA。使用此应用程序功能报告饮酒情况的参与者被纳入分析样本（n = 22）。RTM估计了与酒精供应相关的环境特征以及位于达拉斯市范围内和达拉斯市中心的危险社区特征的空间影响。在全市范围和中心区域分析中，靠近食品银行/收容所和公共图书馆在空间上与AEH饮酒事件地点相关。酒类商店和杂货店的集群也与酒精事件地点显著相关。研究结果为了解AEH饮酒的地理背景提供了见解，并对研究人员和从业者具有启示意义。
