PERSONAL INTERVIEWS |
The method of personal questionnaire based interviewing is highly widespread in market research as well as media research and polls. Questionnaires might differ in form, content and style depending on the area of research. It has the advantage that it involves representative samples so the results are objective and can be generalized to the whole population of the country. With the method of personal questioning even 40-50-minutes’ questionnaires can be completed. In case of long questionnaires and nationally representative research we recommend personal interviews! Our research partner introduced among the first the use of CAPI i.e. laptop interviews which did not only reduce the length of data processing and deadlines but also lead to the reduction of unwillingness to answer. The CAPI method also made it possible to use images, films and audio materials, which helps to carry out more complex, large-sample surveys. Laptop interviews do not only cut costs but also reduce the length of data collection! Personal interviews are used in surveys where the subject requires deeper and more detailed research, but representativity is equally important (e.g. advertisement surveys, satisfaction surveys, marketing research, media research, youth research and political polls).

This type of research uses standard questions; its results are objective, can be recorded numerically and processed statistically. In case of the application of representative samples the results can be generalized to a part or the whole of the population. In the traditional paper-based questioning method, the interviewer records responses on paper whereas in more modern interviews that are supported by computers, interviewers work with a questioning software running on their laptops and record responses directly on the computer. This is a method applied in case of nationally representative surveys involving longer, 30-50-minutes’ questionnaires.
