Rapid household food insecurity (HFI) tracking has been identified as a priority in the context of the COVID-19 pandemic and its aftermath. We report the validation of the Latin American and Caribbean Food Security Scale (Escala Latinoamericana y Caribena de Seguridad Alimentaria [ELCSA]) among pregnant women in Sri Lanka. The eight-item adult version of the ELCSA was translated from English to Sinhala and Tamil. Cognitive testing (on 10 pregnant women and five local experts) and psychometric validation of the self-administered HFI tool were conducted among pregnant women (n = 269) attending the special clinics of the Rajarata Pregnancy Cohort (RaPCo) in Anuradhapura in February 2020. We assessed the psychometric properties and fit using a one parameter logistic model (Rasch model analysis) using STATA Version 14 and WINSTEP software Version 4.3.4. Concurrent validity was tested using psychological distress. The scale was internally consistent (Cronbach's alpha = 0.79) and had a good model fit (Rasch items infit statistic range: 0.85 to 1.07). Item 8 ('did not eat for the whole day') was removed from the model fit analysis, as it was not affirmed by respondent. Item severity scores ranged from -2.15 for 'not eating a diverse diet' to 4.43 for 'not eating during the whole day'. Concurrent validity between HFI and psychological distress was confirmed (r = 0.15, p < 0.05). The self-applied version of ELCSA-pregnancy in Sri Lanka (ELCSA-P-SL) is a valid and feasible valid tool. We recommend it to track HFI among pregnant women in lower income countries during the COVID-19 pandemic.
在 COVID-19 大流行及其后续时期，快速家庭粮食不安全（HFI）跟踪已被确定为优先事项。我们报告了拉丁美洲和加勒比粮食安全量表（Escala Latinoamericana y Caribena de Seguridad Alimentaria [ELCSA]）在斯里兰卡孕妇中的验证情况。ELCSA 的成人八分量表已从英文翻译为僧伽罗语和泰米尔语。认知测试（在 10 名孕妇和 5 名当地专家中进行）和自我管理 HFI 工具的心理测量学验证是在 2020 年 2 月在阿努拉达普拉的拉贾拉特塔妊娠队列（RaPCo）的特殊诊所中进行的。我们使用 STATA 版本 14 和 WINSTEP 软件版本 4.3.4 通过单参数逻辑模型（Rasch 模型分析）评估心理计量学特性和拟合度。使用心理困扰来测试同时效度。该量表具有内部一致性（Cronbach's alpha=0.79），并且具有良好的模型拟合度（Rasch 项目 infit 统计范围：0.85 至 1.07）。由于受访者未确认，因此从模型拟合分析中删除了第 8 项（“一整天都没有吃饭”）。项目严重程度得分范围从“未食用多样化饮食”的-2.15 到“全天未进食”的 4.43。HFI 和心理困扰之间的同时效度得到了确认（r=0.15，p<0.05）。斯里兰卡孕妇的自我应用版 ELCSA-妊娠（ELCSA-P-SL）是一种有效且可行的工具。我们建议在 COVID-19 大流行期间在低收入国家中使用该工具来跟踪孕妇的 HFI。
