Although the CAPI software from the World Bank remains in the beta stage, it has already been deployed to perform actual data collection. The most recent pilot implementation was completed in Djibouti, where our technology helped to conduct an evaluation survey for a World Bank-funded social protection program. Before that, the same technology was tested in St. Lucia, where it was used in the Labour Force Survey.
Djibouti—monitoring and evaluation of a social safety net program
Djibouti Social Protection TA is the first social safety net program in Djibouti combining a public workfare with a nutrition program. Social Protection TA provides short-term employment opportunities in community-based labor-intensive works, and supports the improvement of nutrition practices among participating households, focusing on children under the age of 2 and pregnant and lactating women.
The Computational Tools team of the World Bank was asked to assist in conducting evaluation of the program, making use of the CAPI technology in the data collection process.
As a result, the interviewers that visited households from two neighborhoods in Djibouti City were equipped with Android-based Nexus 7 tablets, which would synchronize with a Survey Management System running on an Amazon EC2 cloud server. Because of that set-up, the collected data were instantly available not only to the statisticians from Djibouti, but also to the team members located in Europe and Washington, DC.
The pilot study has also given the opportunity to test the performance of the software and hardware in more difficult field conditions: low-speed internet connection, bright sunlight and high temperatures. In addition, it highlighted the possibility of using the software in a non-English-speaking environment.
St. Lucia—Labour Force Survey
The quarterly Labour Force Survey is an important tool that informs economic policymaking in St. Lucia. Consequently, ensuring high quality of the collected data is a priority for the national authorities and the Organisation of Eastern Caribbean States, which standardizes the questionnaires and survey protocols across the region.
The World Bank's Computational Tools team provided the statisticians from St. Lucia with a locally-run Survey Management System and the tablet client application. We also delivered training sessions for the interviewers and their supervisors.
Our partners from St. Lucia and the OECS are looking forward to extending the use of CAPI to other surveys and questionnaires.
"The use of CAPI will bring electronic questionnaire design, interviewing, data entry, validation and export together in one place. This will help minimise data entry time and errors, and provide consistent questionnaire delivery in which skip patterns are automatically incorporated"
