简要总结
List experiment to measure food and water insecurity
详细描述
Food and water insecurity are complex, multi-domain constructs. Given their known association with important health and mental health outcomes, accurate assessment of food and water insecurity in resource-limited settings is paramount. The purpose of this study is to use a list experiment methodology to assess the extent to which there is bias in conventional survey-based means of direct elicitation of food and water insecurity. The list experiment provides an indirect means to measure a particular construct of interest. It is hypothesized that social desirability may cause upward bias in conventional survey-based means of direct elicitation of food and water insecurity.

研究组 & 干预措施
Experimental: V1: List No. 1
As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific wording. The first version of the questionnaire includes 6 sets of 3 true-false statements that are innocuous and contextually applicable (e.g., weather, cultural norms) such that there is a low likelihood that the participant will answer untruthfully. The statements on food and water insecurity that are included in the experimental version are omitted.
干预措施: Survey questionnaire (Other)
Experimental: V2: List No. 2
As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific wording. The second version of the questionnaire includes 6 sets of 4 true-false statements that are innocuous and contextually applicable (e.g., weather, cultural norms) such that there is a low likelihood that the participant will answer untruthfully for 3 of the true-false statements. One statement in each set relates to food and water insecurity and is designed to determine the extent to which social desirability bias may influence responses to food and water insecurity questions.

结局指标
主要结局
Going to Sleep Hungry
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, did the participant or one of their household members ever go to sleep hungry because there was not enough food?" (single item, culturally adapted from the 3-item Household Hunger Scale of USAID's Household Food Insecurity Access Scale \[HFIAS\]; response options yes/no)
Going to Sleep Thirsty
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, did the participant or one of their household members ever go to sleep thirsty because there was not enough water?" (single item, culturally adapted to indicate water insecurity, paralleling the 3-item Household Hunger Scale of USAID's Household Food Insecurity Access Scale \[HFIAS\]; response options yes/no)
Drink Unsafe Water
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, did the participant or one of their household members ever drink water that they thought might not be safe for their health?" (single item, culturally adapted to indicate water insecurity, developed specifically for this study; response options yes/no)
No Food Due to Lack of Money
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, was there ever no food to eat in the house because the participant lacked money to buy more?" (single item, culturally adapted from the 3-item Household Hunger Scale of USAID's Household Food Insecurity Access Scale \[HFIAS\]; response options yes/no)
No Water Due to Difficulty Collecting
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, was there ever no water in the participant's house because it was too difficult to collect more?" (single item, culturally adapted to indicate water insecurity, paralleling the 3-item Household Hunger Scale of USAID's Household Food Insecurity Access Scale \[HFIAS\]; response options yes/no)
No Food for Entire Day
时间窗: Baseline (The experimental manipulation in this study has to do with which version of the survey the study participant receives, so the time frame for assessment is immediate even though participants are asked about the past month)
"In the last month, did the participant or one of their household members ever go an entire day and night without eating anything because there was not enough food?" (single item, culturally adapted from the 3-item Household Hunger Scale of USAID's Household Food Insecurity Access Scale \[HFIAS\]; response options yes/no)
