On the basis of a respective briefing we draw up the questionnaire
and, if neccessary, carry out appropriate pretests. We also like
to measure up the questionnaire to our vast experience.
Equipped with our pen-computer-systems (CAPI) or with graphically
well edited questionnaires (paper-pencil) and, if neccessary, with
mobile phones for problem free communication, 1.500 interviewers
do surveying for VALID RESEARCH.
The surveys by telephone are carried out from 60 computer-assisted
work-stations (CATI) from our call center in Bielefeld/Germany.
Since the beginning of the 90´s VALID RESEARCH is actine abroad.
Today we have co-operations with partner-agencies in western and
eastern Europe and also in the United States of America.
We co-ordinate international studies.
The professional employment of standard software and our own instruments,
next to a vast experience helps to analyse the researched data.
