telephone interview

For the main recruitment wave of the LISS panel, a simple random sample of 10,150 addresses was drawn by Statistics Netherlands from the population register. Recruitment of the sampled households was done from May until December 2007 by the field work institute TNS NIPO. The households were contacted in a traditional manner: first an announcement letter was sent along with a brochure explaining the nature of the panel study. The envelope also contained a 10 euro banknote. Next, respondents were approached by an interviewer in a mixed mode design. Households with a known telephone number were contacted by phone (CATI). The other households were visited by an interviewer and thus contacted face-to-face (CAPI). Once the households were contacted, the interviewer asked the respondents to participate in a 10-minute interview, after which they were invited to participate in the panel. Respondents that agreed to participate in the panel were required to confirm their participation by registering on the panel website or by returning a signed response slip.
