Overview Overview of CAPI: description, advantages, disadvantages, products on the market Overview of Survey Solutions features Country examples: Indonesia and Tanzania
What is CAPI? Computer Assisted Personal Interview (CAPI) software allows recording responses on a computer or tablet instead of paper.
What are the advantages of CAPI? Easier Survey Management Reduced variables costs (No transport costs, no storage costs, no printing costs, no data-entry costs) Reduced time from data collection to analysis and reporting Higher quality data (Enforced skip patterns, validation conditions, look-up tables)
What are the advantages of CAPI? Novel question types Geo reference, photos, barcodes scanning (for national IDs) Closer field monitoring Export paradata for monitoring activities during interviews (e.g. start & end time) Almost real time export of micro data export Easier to implement changes to questionnaire No need to send questionnaires back and forth to field
What are disadvantages of CAPI? High fixed cost Can be reduced by using for multiple surveys Requires more preparation time programming and testing questionnaire, procurement Time savings on back-end from no data entry compensates Many times requires connectivity Risks can be reduced by using 2 sim cards, back- up paper questionnaires, etc.
CAPI Products Census and Survey Processing System (CSPro) Developed by the US census bureau and funded primarily by USAID. Widely used, but lacks survey management tools and requires programming knowledge. FREE + programming costs Open Data Kit (ODK): Core developers at UoW Dpt. Of Computer Science. Open-sourced, funded partially through donations of users. FREE+ programming costs My Survey Solutions: Development supported by the GS, and first version released in 09.2013. Closed source, but integrates data management tools, and requires little to no knowledge of programming. FREE
FAO and Survey Solutions Global Strategy has implemented surveys on small sample surveys in Tanzania, Indonesia, and Jamaica World Bank in partnership w/ NSOs have implemented surveys respondents in Malawi, 400K in Uganda, and 2.7 million in SouthAfrica. reaching 200K
Survey Solutions Features User friendly survey management system built right into the software. Survey designer programming skills Cloud based data storage and transfer Geo references questions (holding location) Can accommodate any type of question User-friendly Android application for data entry NO that requires
Survey Solutions Features (contd) Documentation on every part of the system available E-learning course to be available later this year (13 modules) Data export available in SPSS and STATA formats. DDI compliant metadata generated. Automatic paradata monitoring *DDI: Data Documentation Initiative, an int l standard for describing statistical data automatically tabulation for field
Country Experience - Indonesia BPS with technical assistance from the Global Office of the GS agricultural surveys in 2 provinces using SuSo. implemented multiple Data was collected on around 400 households. At the end of the project, BPS purchased 2,000 tablets and is scaling up CAPI to 7 provinces.
Country Experience - Tanzania The Ministry of Livestock and Fisheries Development (MLFD) randomized control trial (RCT) involving 600 livestock extension officers. undertook an CAPI allowed results to be available in less than one month after baseline survey. MLFD looking for more opportunities to expand data collection using CAPI.
