CAPI stands for Computer Assisted Personal Interviewing. This method is very much similar to the PAPI/F2F method, but the data is directly entered into a computer program instead of first using paper forms. The methodology has some limitations in terms of collecting a national representative sample, however it has the great advantage that results are available in real time at client’s end.


DataDiggers conducts CAPI in all the countries where we own proprietary online panels (Bulgaria, Croatia, Czech Republic, Greece, Hungary, Poland, Romania, Serbia, Slovakia and Turkey), as well as around the world via carefully chosen partners.

We do CAPI through local suppliers that own specific data collection devices (tablets, laptops etc.) and have experienced interviewers in major cities of each country.

The online link used to collect data can be either provided by client or our team can program it internally using specialized software.

Quality control

We employ several methods to ensure best quality for the data collected using CAPI methodology:

  • Apart from the project manager that is in permanent contact with client, two senior level local supervisors work on each project, ensuring backup throughout the project and availability of a knowledgeable contact at all times
  • Project materials are proofed for translation by native speakers of each language, to make sure that client’s original goals are not missed due to poor translation
  • Before starting the fieldwork we run an internal quality review of the questionnaire to check the accuracy and make suggestions to client if necessary
  • Interviewers are always briefed before starting the fieldwork, with a special focus on B2B projects, so that they accurately understand project’s challenges and requirements
  • Internal validation of at least 10% of interviews
  • Deliverables are thoroughly checked by two different experienced analysts to ensure accuracy before they are sent over to client.

Works best for ...

  • Challenging B2B or B2C audiences (specific industries or companies, certain managers etc.)
  • Territories where there are no available or reliable online panels or those with a low Internet penetration
  • Areas with poor coverage of phone services
