Face-to-face (personal interview)

 

• A national network of more than 1000 interviewers
• 13 regional supervisors
• A monthly average of 4 000 face-to-face interviews

• detailed briefing is arranged for interviewers
• pilot interviews

The procedures for ensuring F2F interview quality:

• 100% personal control of questionnaires
• minimum 15% of the sample is controlled over the phone
• analytical control of data sets is done – correlation of deviation from the mean by each interviewer; coherence of questionnaires; tracking down of repeating questionnaires
• monthly rotation of interviewers in all cities where tracking research is carried out
