Poverty and socioeconomic status (SES) are conventionally measured through indicators of income, wealth, education and/or occupation, but for some populations such as people who use drugs (PWUD), these measures may not sufficiently capture material well-being. This paper examines the validity of material security, measured through a modified Family Resource Scale (FRS), as an alternative measure of poverty, comparing this to other measures in the context of exposure to violence among PWUD using multivariable generalized estimating equations. Three factors were detected within the FRS using exploratory factor analysis although confirmatory factor analysis did not confirm multifactorial structure. In contrast to other SES measures that had no or positive relationships with exposure to violence, higher FRS scores were associated with lower odds of exposure to violence in final analyses. The FRS thus adds an important perspective to the measurement of poverty, with potential relevance to other populations.

贫困和社会经济地位（SES）通常是通过收入，财富，教育和/或职业指标来衡量的，但是对于某些人群，例如吸毒者（PWUD），这些措施可能无法充分体现物质福祉。本文研究了通过修改后的家庭资源量表（FRS）衡量的物质安全的有效性，作为替代性的贫困衡量标准，并使用多变量广义估计方程将其与在PWUD中遭受暴力侵害的情况下的其他衡量标准进行了比较。尽管确定性因素分析未确认多因素结构，但使用探索性因素分析法在FRS中检测到三个因素。与其他SES措施与暴力暴露没有任何或积极的关系相反，在最终分析中，较高的FRS分数与较低的接触暴力的几率相关。因此，FRS为衡量贫困增加了重要的视角，并可能与其他人群相关。
