Practitioners and researchers use vulnerability indices to understand the conditions that influence hazard risk. However, there has been little research on how well such indices depict household-scale vulnerability to specific hazards. We examined relationships between an all-hazard index and a hazard-specific index with household-level adaptive resources, adaptive behaviors, proximate sensitivities, and self-reported health outcomes related to extreme heat. Household measures were drawn from a stratified random sample survey conducted in Phoenix, Arizona, USA (n = 163). The results point to different experiences between households in more and less heat vulnerable areas. The largest differences between households stratified by the hazard-specific index (Heat Vulnerability Index) primarily involved adaptive resources and behaviors, whereas indicators of proximate sensitivity were more strongly differentiated by the all-hazard index (Social Vulnerability Index). Differences in health outcomes between more and less vulnerable neighborhoods were more evident using HVI than SoVI, although effect sizes using either index were small and confidence intervals were wide. The relationship between vulnerability indices and several survey measures varied across four study sites. The specific ways in which more and less vulnerable communities differ from one another varies based on the adaptation, sensitivity, or outcome measure of interest, location within the city, and choice of vulnerability index.

从业者和研究人员使用脆弱性指数来了解影响危害风险的条件。但是，关于此类指数如何很好地描述家庭规模的特定危害脆弱性的研究很少。我们研究了全危险指数和特定危险指数之间的关系，这些指数与家庭水平的适应性资源，适应性行为，近距离的敏感性以及与极端高温有关的自我报告的健康结果有关。住户测量值来自在美国亚利桑那州凤凰城进行的分层随机抽样调查（n = 163）。结果表明，在越来越少的热脆弱地区，家庭之间的体验不同。根据危害特定指数（热脆弱性指数）分层的家庭之间最大的差异主要涉及适应性资源和行为，而所有危险指数（社会脆弱性指数）则更强烈地区分了接近敏感度的指标。使用HVI比使用SoVI在脆弱程度高的社区和不那么脆弱的社区之间的健康结局差异更明显，尽管使用这两个指数的影响量很小，并且置信区间很宽。脆弱性指数与几种调查措施之间的关系在四个研究地点之间有所不同。越来越多的弱势社区彼此不同的具体方式因适应性，敏感性或兴趣的结果度量，城市中的位置以及脆弱性指数的选择而异。使用HVI比使用SoVI在脆弱程度高的社区和不那么脆弱的社区之间的健康结局差异更明显，尽管使用这两个指数的影响量很小，并且置信区间很宽。脆弱性指数与几种调查措施之间的关系在四个研究地点之间有所不同。越来越多的弱势社区彼此不同的具体方式因适应性，敏感性或兴趣的结果度量，城市中的位置以及脆弱性指数的选择而异。使用HVI比使用SoVI在脆弱程度高的社区和不那么脆弱的社区之间的健康结局差异更明显，尽管使用这两个指数的影响量很小，并且置信区间很宽。脆弱性指数与几种调查措施之间的关系在四个研究地点之间有所不同。越来越多的弱势社区彼此不同的具体方式因适应性，敏感性或兴趣的结果度量，城市中的位置以及脆弱性指数的选择而异。
