This study examined the internal validity of an adapted version of the U.S. Household Food Security Survey Module administered to a sample of 241 pregnant Latinas. Single-parameter logistic (Rasch) measurement model was used to assess the psychometric properties of the adapted module. Two of 14 questions examined did not fit within the acceptable range (0.70-1.30). The severity level of 12 of the 14 questions was similar across two time periods, before pregnancy and the past month of pregnancy. These findings suggest the adapted module is valid for use among pregnant Latinas, yet some items might not be applicable during pregnancy.
本研究对241名怀孕的拉丁裔女性样本进行了美国家庭粮食安全调查模块改编版的内部效度检验。采用单参数逻辑斯蒂（拉施）测量模型评估改编版模块的心理测量特性。所检验的14个问题中有2个不符合可接受范围（0.70 - 1.30）。14个问题中的12个问题的严重程度在怀孕前和怀孕最后一个月这两个时间段内相似。这些结果表明，改编版模块在怀孕的拉丁裔女性中使用是有效的，但某些项目在怀孕期间可能不适用。
