Abstract CentERdata operates a telepanel, in which the respondents fill in a questionnaire each week on their computer. The panel now is seven years old. This raises the question how long respondents may be allowed to stay a member of the panel. Part of this question can be answered by examining the attrition bias. If ‘old’ panel members differ systematically from ‘new’ members with respect to variables that can not be controlled in the selection process this would be a reason to limit panel membership. The analysis shows that there are no such differences with respect to a large range of psychological variables.
