该二次分析评估了美国农业部家庭食品安全调查模块（HFSSM）在拉丁裔移民人口中的简短版本的有效性。Rasch模型评估了HFSSM的结构、项目严重程度和样本总体的适应度。微分项功能(DIF)分析的不变性进行了探讨HFSSM少/多文化家庭之间的响应模式。项目infit得分在适当范围内（0.7-1.3）。项目严重程度评分和单维度结构支持了该量表的理论框架。分析显示，不同文化适应水平之间的差异无统计学意义。改编后的HFSSM与拉丁裔移民人口中粮食不安全管理过程的理论框架一致。
This secondary analysis evaluated the validation of the short version of the US Department of Agriculture’s Household Food Security Survey Module (HFSSM) in a Latino migrant population. The Rasch model assessed the HFSSM’s structure, item severity levels, and fitness of the sample population. Differential item functioning (DIF) analysis explored the invariance of HFSSM response patterns between less/more acculturated households. Item infit scores were within an adequate range (0.7–1.3). Item severity scores and unidimensionality structure supported the HFSSM’s theoretical framework. Analysis showed statistically nonsignificant DIF contrast between acculturation levels. The adapted HFSSM performed in agreement with the theoretical framework of food insecurity as a managed process in this Latino migrant population.
