最近为确定美国粮食不安全和饥饿的程度而进行的调查，即《粮食安全补编》，包括一系列问题，以评估这一复杂现象。根据这份《粮食安全补充材料》制定的主要衡量标准是基于先前制定的两项衡量标准的衡量概念、方法和项目。本文介绍了现有的证据表明，基于粮食安全的措施，特别是国家粮食安全措施，提供有效的粮食不安全和饥饿的人口和个人用途的测量，本文讨论了测量的基本思想和标准，建立有效的措施，然后使用这些标准结构的研究结果，以建立有效的粮食安全措施的检查。结果表明，国家粮食安全措施的构建充分基于我们对粮食不安全和饥饿的理解，其绩效与这种理解是一致的，在通常的绩效标准内是精确的，在合理的绩效标准内，在群体和个人层面上都是可靠、准确的，其准确性归因于有根据的理解。这些结果提供了强有力的证据，表明粮食安全补充为人口和个人使用提供了有效的粮食不安全和饥饿衡量标准。需要对尚未为验证目的进行研究的人口亚群进行进一步验证研究，以确定监测人口流行率变化的有效性，并在不同国家制定和验证反映人们如何经历和思考粮食不安全和饥饿的强有力和对背景敏感的措施。
The most recent survey effort to determine the extent of food insecurity and hunger in the United States, the Food Security Supplement, included a series of questions to assess this complex phenomenon. The primary measure developed from this Food Security Supplement was based on measurement concepts, methods and items from two previously developed measures. This paper presents the evidence available that questionnaire-based measures, in particular the national food security measure, provide valid measurement of food insecurity and hunger for population and individual uses, The paper discusses basic ideas about measurement and criteria for establishing validity of measures and then uses these criteria to structure an examination of the research results available to establish the validity of food security measures. The results show that the construction of the national food security measure is well grounded in our understanding of food insecurity and hunger, its performance is consistent with that understanding, it is precise within usual performance standards, dependable, accurate at both group and individual levels within reasonable performance standards, and its accuracy is attributable to the well-grounded understanding. These results provide strong evidence that the Food Security Supplement provides valid measurement of food insecurity and hunger for population and individual uses. Further validation research is required for subgroups of the population, not yet studied for validation purposes, to establish validity for monitoring population changes in prevalence and to develop and validate robust and contextually sensitive measures in a variety of countries that reflect how people experience and think about food insecurity and hunger.
