6至17岁的儿童能够准确评估自己的粮食不安全状况，而父母却不能准确地报告孩子的粮食不安全经历。尚未制定和验证全球适用的评估儿童粮食不安全的量表。我们的目标是制定一种全球适用的、基于经验的儿童和青少年粮食不安全衡量标准，并确定该衡量标准的有效性和跨背景等效性。包含 10 项的儿童粮食不安全经历量表 (CFIES) 基于之前从美国、委内瑞拉和黎巴嫩的调查问卷中验证的项目。进行认知访谈以检查对这些项目的理解。随后，该问卷在 13 个国家的 15 项调查中进行。每项调查中评估家庭社会经济状况、家庭粮食安全或儿童心理功能的其他项目都被选为标准变量，与 CFIES 的分数进行比较。为了研究准确性（即标准有效性），线性回归估计了 CFIES 分数与标准变量的关联。为了研究跨上下文等价性（即测量不变性），使用基于经典测量理论的对齐方法。在 15 项调查中，CFIES 的平均量表分数范围为 1.65 至 5.86（可能范围为 0 至 20），Cronbach alpha 范围为 0.88 至 0.94。一因子模型解释的方差范围为 0.92 至 0.99。准确性通过与标准变量的预期关联来证明。 15 项调查中等效阈值和负载的百分比分别为 28.0 和 5.33，非等效阈值和负载的总百分比为 16.7，远低于 <25% 的准则。 也就是说，这些调查中 83.3% 的阈值和负载是相同的。 CFIES 针对学龄儿童和青少年报告的粮食不安全经历提供了全球适用、有效且跨背景的等效衡量标准。
Children ages 6 to 17 years can accurately assess their own food insecurity, whereas parents are inaccurate reporters of their children's experiences of food insecurity. No globally applicable scale to assess the food insecurity of children has been developed and validated. We aimed to develop a globally applicable, experience-based measure of child and adolescent food insecurity and establish the validity and cross-contextual equivalence of the measure. The 10-item Child Food Insecurity Experiences Scale (CFIES) was based on items previously validated from questionnaires from the United States, Venezuela, and Lebanon. Cognitive interviews were conducted to check understanding of the items. The questionnaire then was administered in 15 surveys in 13 countries. Other items in each survey that assessed the household socioeconomic status, household food security, or child psychological functioning were selected as criterion variables to compare to the scores from the CFIES. To investigate accuracy (i.e., criterion validity), linear regression estimated the associations of the CFIES scores with the criterion variables. To investigate the cross-contextual equivalence (i.e., measurement invariance), the alignment method was used based on classical measurement theory. Across the 15 surveys, the mean scale scores for the CFIES ranged from 1.65 to 5.86 (possible range of 0 to 20) and the Cronbach alpha ranged from 0.88 to 0.94. The variance explained by a 1-factor model ranged from 0.92 to 0.99. Accuracy was demonstrated by expected associations with criterion variables. The percentages of equivalent thresholds and loadings across the 15 surveys were 28.0 and 5.33, respectively, for a total percentage of nonequivalent thresholds and loadings of 16.7, well below the guideline of <25%. That is, 83.3% of thresholds and loadings were equivalent across these surveys. The CFIES provides a globally applicable, valid, and cross-contextually equivalent measure of the experiences of food insecurity of school-aged children and adolescents, as reported by them.
