背景：在美国，男男性行为者（MSM）感染人类免疫缺陷病毒（HIV）的风险较高，且HIV相关预后较差。地图可用于识别、量化和解决艾滋病毒阳性男男性行为者在获得艾滋病毒护理方面的差距，并根据所服务患者的需求定制干预方案。目的：本研究的目的是评估在基于网络的亚特兰大艾滋病毒阳性男男性行为者调查中嵌入的谷歌地图问题的可用性，并确定它是否是收集居住地和最后艾滋病毒护理提供者地址数据的有效和可靠的替代方案。方法：通过Facebook和两项正在进行的主要通过基于场所的抽样或同伴推荐（VBPR）招募的研究招募了亚特兰大的艾滋病毒阳性男男性行为者。参与者被要求使用两种方法来确定他们的居住地和最后一次参加艾滋病毒护理提供者的位置：(1)通过输入街道地址（金标准），(2)使用嵌入式谷歌地图“点击”这些位置。对家庭和提供者地址进行地理编码、映射，并与点击地图点的家庭和提供者位置进行比较，以评估有效性。供应商位置误差值与家庭位置误差值相对应，并计算kappa统计值，以评估识别住宅位置与供应商位置的误差程度的一致性。结果：所有参与者的家庭位置误差中位数为0.65英里（四分位数范围，IQR, 0.10, 2.5英里），Facebook参与者的家庭位置误差中位数较低(P
Background: Men who have sex with men (MSM) in the United States are at high risk for human immunodeficiency virus (HIV) and poor HIV related outcomes. Maps can be used to identify, quantify, and address gaps in access to HIV care among HIV-positive MSM, and tailor intervention programs based on the needs of patients being served.Objective: The objective of our study was to assess the usability of a Google map question embedded in a Web-based survey among Atlanta-based, HIV-positive MSM, and determine whether it is a valid and reliable alternative to collection of address-based data on residence and last HIV care provider.Methods: Atlanta-based HIV-positive MSM were recruited through Facebook and from two ongoing studies recruiting primarily through venue-based sampling or peer referral (VBPR). Participants were asked to identify the locations of their residence and last attended HIV care provider using two methods: (1) by entering the street address (gold standard), and (2) "clicking" on the locations using an embedded Google map. Home and provider addresses were geocoded, mapped, and compared with home and provider locations from clicked map points to assess validity. Provider location error values were plotted against home location error values, and a kappa statistic was computed to assess agreement in degree of error in identifying residential location versus provider location.Results: The median home location error across all participants was 0.65 miles (interquartile range, IQR, 0.10, 2.5 miles), and was lower among Facebook participants (P
