During the first three years (2013-2015), the panel was reserved for the sole use of the teams of the DIME-SHS consortium. This pilot study was a necessary step, in order to implement the methodology and the IT tools, and to experiment and assess the system.
A first sample of about 1,000 panel members was recruited in 2012 for this pilot phase. Different contact modes were tested (mail, face-to-face, phone), as well as the effect of vouchers as incentives. In addition, the implementation of questionnaires on tablet, the length of surveys, the conditioning and professionalization of the respondents and the ways to limit attrition were subject of experimentation during the pilot phase
The calls for projects were open to the entire national and international scientific community since 2015.
