Socio-Economic/Monitoring Survey [hh/sems]
The World Bank is providing support to the Royal Government of Cambodia to help mitigate the spread and impactof the 2019 coronavirus disease (COVID-19) pandemic. One area of support is data collection. Data will provideevidence that will inform the government response. This effort is part of a broader World Bank initiative, aiming atconducting national longitudinal or cross-sectional high-frequency survey data that can be used to help assessthe economic and social implications of the COVID-19 pandemic on households and individuals across the World.The Cambodia COVID-19 High Frequency Phone Survey (HFPS), IDPoor draws its sample from the beneficiary list of the conditional cash transfer program for pregnant and child under 2.
To monitor the socioeconomic impacts of the coronavirus disease 2019 (COVID-19) pandemic and inform policy responses and interventions, the COVID-19 High-Frequency Phone Survey (HFPS) of households was designed as part of a World Bank global initiative. For Cambodia, a total of 5 survey rounds are planned, with households being called back every 1 to 2 months. This allows for the impact of the pandemic to be tracked as it unfolds and provides data to the government and development partners in near real-time, supporting an evidence-based response to the crisis.
In June 2020, Cambodia launched a Cash Transfer Program to support poor and vulnerable households during COVID-19. To more closely monitor the impact of COVID-19 among poor and vulnerable households in Cambodia and the impact of the Cambodia's Cash Transfer Program for Poor and Vulnerable Households during COVID-19, a sample of 1,000 IDPoor households was drawn for the phone survey from the beneficiary list of the conditional cash transfer for pregnant women and children under 2.
The questionnaire covers a series of topics, such as knowledge of Covid-19 and social behavior, access to food, food insecurity, impact of the Covid-19 on income sources and coping mechanisms, access to social assistance, and impact of Covid-19 on economic activity. A modular approach is used in the questionnaire design, which allows for modules to be dropped and/or added in different waves/rounds of the survey. The questionnaire is designed to be administered between 20 to 25 minutes.
Data collection for the first round started in June 2020. The survey is implemented using Computer Assisted Telephone Interviewing.

Sampling
The beneficiary list of the conditional cash transfer program for pregnant women and child under 2 was assigned into 5 strata i.e. Phnom Penh and other urban areas, Plain, Tonle Sap, Coastal, Plateau and Mountain. The sample was randomly selected with proportional to the size of the IDPoor households in each strata. The phone survey successfully interviewed 984 households in June (Round 1). In August (Round 2), 784 households have been re-interviewed and 271 replacement households were added. Of these, 841 were successfully reached again in October (Round 3), with 527 interviewed in all three rounds. In December, 1,277 households were successfully interviewed, of which 945 households were re-contacted and 332 households were added as replacement households. In March 2021, 1,309 households were interviewed, of which 991 households were re-interviewed and 318 households were replacement households. In February 2022, 812 households were successfully interviewed while only 801 households were interviewed in April 2022.
Replacement sampling approach was applied to reach the target sample.
Sampling weights were computed by dividing the total IDPoor household in each region (Phnom Penh and other urban areas, Plains, Tonle Sap, Coastal, Plateau and Mountains) by its respective sample size.

The Cambodia COVID-19 High-Frequency Phone Survey of Households (HFPS) was conducted using Computer Assisted Telephone Interview (CATI) techniques. The household questionnaire was implemented using the CATI software, Survey Solution.
Enumerators used their own mobile phone devices. Enumerators were given data bundles, allowing for internet connectivity and daily synchronization with the server. Data was sent to the server daily.
Field Supervisors reviewed the survey with enumerators on a daily basis via one-on-one calls and were always available to address any concerns that arose while performing an interview. At the same time, a Research Analyst was in charge of checking the uploaded data daily to identify errors and notify supervisors so as to avoid further errors during ongoing survey implementation and future surveys.
A dashboard was established and updated daily. The dashboard has information on individual enumerator performance, such as the number of calls logged, duration of calls, percentage of calls responded to and percentage of non-consents. Non-consent reason rates and attempts per household were monitored as well. The dashboard was also used to track overall survey completion and preview the results of key questions.
Field Supervisors made callback checks to a random subsample of households that completed a survey in Round 1. Field Supervisors called these households and administered a short survey, including (i) identifying the same respondent; (ii) determining the respondent's position within the household; (iii) confirming that a member of the data collection team had completed the interview; and (iv) a few questions from the original survey.
Data processing
At the end of data collection, the raw dataset was cleaned by the research team. This included formatting, and correcting results based on monitoring issues, enumerator feedback and survey changes.
Only households that consented to being successfully interviewed were kept in the dataset, and all personal information and internal survey variables were dropped from the clean dataset.
