Intervention (Public)
|
Before
We employ over-the-phone interventions designed to improve 1) social distancing, and 2) knowledge relating to COVID-19.
Social Distancing Treatments:
-SD1: Information on the value of social distancing. We will provide individuals with information on the value of social distancing, emphasizing the positive externality they confer on others by reducing the spread of COVID-19.
-SD2: Community Support for Social Distancing. We will ask individuals whether they themselves support social distancing, and use this information to calculation the fraction of households in the community who support social distancing. We will then ask them to guess the share of households in the community who support social distancing. In a later phone call, households who underestimate the true share of households in the community who support social distancing will be given information on the true (higher) share of support for social distancing. We will accompany this message with information on the value of social distancing, emphasizing the positive externality they confer (same information provided in Treatment SD1).
-SD3: Community leader support for social distancing. Community leaders have also participated in past rounds of our surveys. We will survey community leaders again, and ask them to endorse social distancing in their communities. In this treatment, we will inform households by phone call that these individuals support social distancing in their communities. We will accompany this message with information on the value of social distancing, emphasizing the positive externality they confer (the same information provided in Treatment SD1).
Knowledge Treatments:
-K1: Knowledge Incentives. We will randomly offer a subset of respondents an additional monetary reward for every correct knowledge response on a subsequent phone survey. We will examine the effect of the treatment on future knowledge and behavior.
-K2 & 3: Tailored Feedback. We will randomly give tailored feedback to a subset of respondents on their response to COVID-19 knowledge questions, by informing them of a subset of their correct responses and correcting a subset of their incorrect responses. We will examine if tailored feedback improves relevant knowledge and behavior in a subsequent telephone survey.

We implement over-the-phone interventions to 1) encourage social distancing by accelerating changes in community norms, and 2) improve knowledge about COVID-19
Social Distancing Treatments:
-SD1: Community Support for Social Distancing. We will ask individuals whether they themselves support social distancing, and use this information to calculate the fraction of households in the community who support social distancing. Then, in a later phone call, we will ask individuals to guess the share of households in the community who support social distancing. Individuals who underestimate the true share of households in the community that support social distancing will be given information on the true (higher) share of support for social distancing, and individuals correctly guessing the true share will be told that their guess is correct.
-SD2: Community leader support for social distancing. We will survey community leaders and ask them to endorse social distancing in their communities. In this treatment, we will inform households by phone call that their leaders support social distancing in their communities.
Knowledge Treatments:
-K1: Knowledge Incentives. We will randomly offer a subset of respondents 5 Mozambican meticais (MT) for every correct knowledge response on a subsequent phone survey. We will examine the effect of the treatment on future knowledge and behavior. If they answer all 40 questions correctly, respondents can earn a maximum of 200MT (approx. US$2.86).
-K2: Tailored Feedback. We will randomly give tailored feedback to a subset of respondents based on their response to COVID-19 knowledge questions, by informing them of a subset of their correct responses and correcting a subset of their incorrect responses. We will examine if tailored feedback improves relevant knowledge and behavior in a subsequent telephone survey.

Primary Outcomes (Explanation)
|
Before
For Social Distancing interventions:
-Others’ and self-report of social interactions: Others’ reports of social interactions with respondent. Taken from the question ask for up to 10 other study participants in one’s social network and neighbors within 200m: Did you talk to / stand within 1.5 meters / shake hands or otherwise touch (insert name) in last 14 days?
-Index of household social distancing behaviors: Ask about whether or not the household attends social gatherings, leaves the household area, avoids crowded areas, keeps a distance of 1.5 meters from others, frequently wash hands, informs others if sick, and more…
◦ Is this something you think people should be doing?
◦ Is this something your household has been doing for the last 7 days?
For Knowledge interventions:
-Index of COVID-19 overall knowledge - number of correct responses to knowledge questions about coronavirus symptoms, prevention, how it spreads, and who is most at risk; household social distancing and self-prevention behaviors. Confidence with which responses are given.
|
After
For Social Distancing interventions:
The primary outcome will be an indicator for the respondent practicing social distancing. It will be constructed from two component indicators: the own report of practicing social distancing, and others’ report of the respondent’s practicing social distancing. The primary outcome will be equal to one if both the own report and others’ report of practicing social distancing is equal to one, and zero otherwise. Some detail below and see Analysis Plan for further details.
-Others’ and self-report of social interactions: Others’ reports of social interactions with respondent. Taken from the question ask for up to 10 other study participants in one’s social network and neighbors within 200m: Did you talk to / stand within 1.5 meters / shake hands or otherwise touch (insert name) in last 14 days?
-Index of household social distancing behaviors: Ask about whether or not the household attends social gatherings, leaves the household area, avoids crowded areas, keeps a distance of 1.5 meters from others, frequently wash hands, informs others if sick, and more…
◦ Is this something you think people should be doing?
◦ Is this something your household has been doing for the last 7 days?
For Knowledge interventions:
-Index of COVID-19 overall knowledge - number of correct responses to knowledge questions about coronavirus symptoms, prevention, how it spreads, and who is most at risk; household social distancing and self-prevention behaviors. Confidence with which responses are given.
