Abstract
In March 2011, the LISS panel completed a questionnaire about impending data enrichment. This data enrichment means that CentERdata, in collaboration with Statistics Netherlands, may combine respondents’ answers in LISS questionnaires with information about the respondent known to Statistics Netherlands.
This questionnaire aims to gain insight into how respondents can best be informed about this enrichment. To this end, first various emails and letters were sent to 745 panel members. These panel members were divided into four experimental groups:
Group 1 = received brief text by email
Group 2 = received brief text by letter
Group 3 = received extensive text by email
Group 4 = received extensive text by letter
This questionnaire investigates whether respondents have understood the information provided to them in the previously sent email or letter, and whether this notification affects the respondents’ attitude towards privacy issues. To research the latter aspect, a control group was selected consisting of 500 randomly chosen households (including all household members of age 16 and over). This control group was only presented the questions about privacy.
