背景资料：适应不良行为可能会更充分地理解和有效地防止流动工具，评估人们的持续经验，在他们的context of their environment.Methods：展示新的现场部署的方法，评估情绪和行为作为一个功能的邻里环境（地理瞬时评估; GMA），我们收集了时间戳GPS数据和生态瞬时评估（EMA）评级的情绪，压力，在接受美沙酮维持治疗的阿片类药物依赖性多种药物使用者清醒时随机提示的时间超过16周的药物渴望。EMA入口的位置和参与者的旅行轨迹计算的12个之前，每个EMA入口被映射。主观评级和客观环境评级之间的关联进行了评估，在整个街区和12小时的轨道level.Results：参与者（N=27）符合GMA数据收集; 3711随机提示EMA条目匹配到特定的位置。在社区水平上，身体障碍与消极情绪、压力、海洛因和可卡因渴望呈负相关（ps < .0001-.0335）;药物活动与压力、海洛因和可卡因渴望呈负相关（ps <.0009-.0134）。在EMA进入前12 h，受访者的轨道周围的环境中也发现了类似的关系。结论：结果支持GMA的可行性。邻里特征和参与者的报告之间的关系是违反直觉和反假设的，并挑战一些假设，表面上的压力环境是如何与生活经验，以及这些环境最终如何损害健康。全球海洋环境状况评估方法可用于制定个人或社区一级的干预措施。出版社：Elsevier爱尔兰Ltd.
Background: Maladaptive behaviors may be more fully understood and efficiently prevented by ambulatory tools that assess people's ongoing experience in the context of their environment.Methods: To demonstrate new field-deployable methods for assessing mood and behavior as a function of neighborhood surroundings (geographical momentary assessment; GMA), we collected time-stamped GPS data and ecological momentary assessment (EMA) ratings of mood, stress, and drug craving over 16 weeks at randomly prompted times during the waking hours of opioid-dependent polydrug users receiving methadone maintenance. Locations of EMA entries and participants' travel tracks calculated for the 12 before each EMA entry were mapped. Associations between subjective ratings and objective environmental ratings were evaluated at the whole neighborhood and 12-h track levels.Results: Participants (N=27) were compliant with GMA data collection; 3711 randomly prompted EMA entries were matched to specific locations. At the neighborhood level, physical disorder was negatively correlated with negative mood, stress, and heroin and cocaine craving (ps < .0001-.0335); drug activity was negatively correlated with stress, heroin and cocaine craving (ps.0009-.0134). Similar relationships were found for the environments around respondents' tracks in the 12 h preceding EMA entries.Conclusions: The results support the feasibility of GMA. The relationships between neighborhood characteristics and participants' reports were counterintuitive and counter-hypothesized, and challenge some assumptions about how ostensibly stressful environments are associated with lived experience and how such environments ultimately impair health. GMA methodology may have applications for development of individual- or neighborhood-level interventions. Published by Elsevier Ireland Ltd.
