缓解家庭用水不安全被认为是全球减贫的重要组成部分，但直到最近还很难衡量。已经提出并验证了几种衡量家庭用水不安全的新指标，但很少有经过不同环境下可靠性的现场测试。我们使用验证性因子分析来测试此类指标（家庭水不安全经历 (HWISE) 量表）的心理测量等效性，该指标在加纳阿克拉以外的城郊社区的家庭中，在相似的气候条件下，相隔 18 个月进行了两次调查。 HWISE 指标在不同的调查波中并不相同，这可能归因于指标本身、样本大小、微妙的仪器变化或其他未观察到的因素。鉴于家庭用水的动态性质，重测可靠性也可能难以实现，我们讨论了使用家庭水不安全指标作为全球反贫困计划中福祉的纵向衡量标准的影响。
The mitigation of household water insecurity is recognized as an important component of global poverty alleviation, but until recently was difficult to measure. Several new metrics of household water insecurity have been proposed and validated, but few have been field-tested for reliability in diverse contexts. We used confirmatory factor analysis to test the psychometric equivalence of one such metric—the Household Water Insecurity Experiences (HWISE) scale—across two survey waves administered 18 months apart in similar climatic conditions among households in a peri-urban community outside of Accra, Ghana. The HWISE metric was not equivalent across survey waves, which may be attributable to the metric itself, sample size, subtle instrumentation changes, or other unobserved factors. Test-retest reliability may also be difficult to achieve given the dynamic nature of household water use, and we discuss the implications of using household water insecurity metrics as longitudinal measures of well-being in global anti-poverty programs.
