List experiment to measure food and water insecurity
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental: V1: List No. 1 | Experimental | 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. |
|
| Experimental: V2: List No. 2 | Experimental | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Survey questionnaire | Other | Each version of the questionnaire includes a different number of true-false statements that study participants are asked to identify. |
|
| Measure | Description | Time Frame |
|---|---|---|
| No Food Due to Lack of Money | "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) | 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) |
| No Water Due to Difficulty Collecting | "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) | 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) |
| Going to Sleep Hungry | "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) | 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) |
| Going to Sleep Thirsty | "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) |

Study participants are asked to identify the number of true statements in a list, where the number of true statements is randomly assigned. Neither study participants nor outcomes assessors are provided with information about "treatment" assignment.
