In 2006 health insurer VGZ initiated, together with NIVEL the Insurance Panel. The panel consists of approximately 12,000 members who are insured via one of the health insurance plans of VGZ. The members have agreed to receive a questionnaire on developments in healthcare and health insurance four times a year. The panel is part of the Academic Research Working Place on Health Insurance.
Different methods of data collection
The panel members are recruited via a call in the newsletter from their insurer or by telephone or email. There are about seven to 10 questionnaires per year, but individual panel members receive a maximum of four questionnaires per year. Questionnaires can be send by post or answered online. Sometimes telephone surveys or focus groups (both online and face-to-face) are organized.
