The objectives of this study were to: 1) assessed the face validity of the 18-items US Household Food Security Scale Module (US HFSSM) among low-income pregnant Latinas and 2) adapt the US HFSSM to the target population. This study was conducted in the United States in Hartford, Connecticut where 40% of residents are of Latina descent. Three focus groups (N=14(total)) were held with pregnant and postpartum Latinas from April - June 2004 to assess the understanding and applicability (face validity) of the US HFSSM as well as adapt the US HFSSM based on their recommendations. This was followed by pre-testing (N=7) to make final adaptations to the US HFSSM. Overall, the items in the US HFSSM were clear and understandable to participants, but some questions sounded repetitive to them. Participants felt the questions were applicable to other pregnant Latinas in their community and shared food security related experiences and strategies. Participants recommendations led to key adaptations to the US HFSSM including reducing the scale to 15-items, wording statements as questions, including two time periods, replacing the term "balanced meals" with "healthy and varied", replacing the term "low cost foods" with "cheap foods" and including a definition of the term, and including a coping mechanism of avoiding running out of food. The adapted US HFSSM was found to have good face validity among pregnant Latinas and can be used to assess food insecurity among this vulnerable population.
1）评估18项美国家庭粮食安全量表模块（US HFSSM）在低收入拉丁裔孕妇中的表面效度，以及2）使US HFSSM适用于目标人群。本研究在美国康涅狄格州哈特福德进行，那里40%的居民为拉丁裔后裔。2004年4月至6月，与怀孕和产后的拉丁裔女性进行了三个焦点小组访谈（共14人），以评估US HFSSM的理解度和适用性（表面效度），并根据她们的建议对US HFSSM进行调整。随后进行了预测试（7人），以对US HFSSM进行最终调整。总体而言，US HFSSM中的项目对参与者来说清晰易懂，但有些问题他们听起来觉得重复。参与者认为这些问题适用于她们社区中的其他拉丁裔孕妇，并分享了与粮食安全相关的经历和策略。参与者的建议导致了对US HFSSM的关键调整，包括将量表缩减至15项，将陈述措辞改为问题，包括两个时间段，将“均衡膳食”一词替换为“健康多样”，将“低成本食品”一词替换为“便宜食品”并给出该词的定义，以及纳入避免食物耗尽的应对机制。调整后的US HFSSM在拉丁裔孕妇中具有良好的表面效度，可用于评估这一弱势群体中的粮食不安全状况。
