Other Household Health Survey [hh/hea]
To monitor how the COVID-19 pandemic affects STP’s economy and population and substantiate response policies with data, INE, with technical support from the World Bank (WB), has designed and conducted two rounds of a telephone Household Monitoring Survey (HMS). With support from the United Nations, the first-round survey was expanded to include a questionnaire aimed at informal businesses. Round 1 was conducted from 2020/07/26 to 2020/08/08, and Round 2 was conducted from 2021/01/28 to 2021/02/04.
The first recorded cases of COVID 19 in São Tomé and Príncipe (STP) emerged on April 6, 2020. Since then, the Government has implemented strict measures to contain the spread of the virus. In addition, the closure of air space has drastically reduced air transport activities, making it difficult to carry out one of the most important activities in the country, which is Hotel and Catering (Tourism) as well as non-food trade activities.
The COVID-19 pandemic and its economic and social impacts on families have created an urgent need for up-to-date data to help monitor and mitigate the impacts of the crisis and protect the well-being of the least favored in STP society. To monitor how the COVID-19 pandemic affects STP’s economy and population and to substantiate response policies with data, the National Statistical Institute (INE), with technical support from the World Bank, has designed and conducted a telephone Household Monitoring Survey (HMS). With support from the United Nations, the survey was expanded to include a questionnaire aimed at informal businesses.

Scope
The STP COVID-19 HMS Round 1 consists of two questionnaires.
The Household Questionnaire was administered to all households in the sample. The Informal Businesses Questionnaire was administered to households holding informal businesses.
Household Questionnaire: collected information on demographics; knowledge regarding the spread of COVID-19; behavior and social distancing; access to basic services; employment; income loss; and food security.
Informal Businesses Questionnaire: collected information on the impacts of COVID-19 on the household informal business regarding impacts on the labor force; profit and sales; production; how the pandemic impacted the business; and plans for the future.
The contents of both questionnaires are outlined in section 6 of the Basic Information Document, provided under the Documentation tab.
Round 2 - The Household Questionnaire collected information on
General household information; Knowledge about the spread of COVID-19; Access (to medicine, health services, education, food etc); Major Food Insecurity Experience Scale; Loss of Income; COVID-19 Vaccine
Coverage
This survey included all districts: Lembá, Lobata, Água Grande, Me Zochi, Cantagalo, Cauê, and the Príncipe Autonomous Region (RAP).

Sampling
The STP COVID-19 HMS sample consists of a subsample of the Multiple Indicator Cluster Survey (MICS) carried out by INE in collaboration with UNICEF in 2019. Households with access to a telephone are represented in the HMS, covering urban and rural areas in all STP regions. The HMS called all households with a valid telephone number listed in MICS, completing 1,025 interviews (413 in rural areas and 612 in urban areas).
Among the 3,426 households interviewed in the MICS 2019, 1,400 (40.8%) provided at least one phone number. From these, 1,081 were successfully contacted by INE interviewers and 1,025 accepted and answered all the questions made in the first round of the HMS.
To mitigate bias in a sample that contains only households with a working telephone, a procedure for adjusting the sample weights was carried out using the Propensity Score Weighting (PSW) methodology. Following this procedure, the HMS results were brought closer to the national representativeness of surveys carried out in person, such as MICS 2019.
Sample size was 1,400 households, of which 1,025 completed the forms in full.

The STP COVID-19 HMS exercise was conducted using Computer Assisted Telephone Interview (CATI) techniques. The household questionnaire was implemented using the CATI software, Survey Solutions. The Survey Solutions software was developed and maintained by the Data Analytics and Tools Unit within the Development Economics Data Group (DECDG) at the World Bank. Overall, implementation of survey using Survey Solutions CATI was highly successful, as it allowed for timely availability of the data from completed interviews.
Field Work
Organization of the Fieldwork
Personnel were selected from the pool of INE interviewers and trained to use Survey Solutions platform and conduct phone surveys. Data were collected by these trained INE interviewers who individually made phone calls from their respective homes. Since the country was on lockdown during the preparation and data collection exercise for the baseline round, interviewers were not allowed to be in the office. Therefore, all interviews were conducted from interviewers’ homes.
Gift to Households
As a show of appreciation for the households’ participation, all households that gave consent to be interviewed, were transferred 25 dobras credit to their phones (even if their interviews are only partially completed).
Pre-loaded Information
Basic information on every household was pre-loaded in the CATI assignments for each interviewer. The information was pre-loaded to (1) assist interviewers in calling and identifying the household and (2) ensure that each pre-loaded person is properly addressed and easily matched to the most recent interviews. Basic household information (location, names, phone number, etc.) was pre-loaded. The list of individuals from the previous interview and their basic characteristics were uploaded. This helped maintain the panel of individuals and ensured the status of each individual in the subsequent round of the survey.
Respondents
Each round of the STP COVID-19 HMS has ONE RESPONDENT per household. The respondent was the household head or a knowledgeable adult household member. The respondent must be a member of the household. Unlike many other household surveys, interviewers were not expected to seek out other household members to provide their own information. The respondent may still consult with other household members as needed to respond to the questions, including to provide all the necessary information on each household member.
Interviewers were instructed to make every effort to reach the same respondent in subsequent rounds of the survey, in order to maintain the consistency of the information collected. However, in cases where the previous respondent was not available, interviewers would identify another knowledgeable adult household member to interview.
Data processing
Data Cleaning
The data cleaning process was done in two main stages. The first stage was to ensure proper quality control during the fieldwork. This was achieved in part by incorporating validation and consistency checks into the Survey Solutions application used for the data collection and designed to highlight many of the errors that occurred during the fieldwork.
The second stage of cleaning involved a comprehensive review of the final raw data following the first stage cleaning. Every variable was examined individually for (1) consistency with other sections and variables, (2) out of range responses, and (3) formatting. Some minor errors remain in the data where the diagnosis and/or solution were unclear to the data cleaning team.
