Abstract:

Based upon our good experiences with the use of a panel, we wondered whether it would be possible to use this same panel systematically for psychological research. From Mr. Koponen's literature we understood that he has achieved quite a lot in this field. Furthermore, it was known to us that large research-agencies, specialised in psychological research, are also frequently using panels. This, however, is generally done on a more limited scale and by way of verbal interviewing.
