Why is there little use of open-ended questions in the questionnaire(s)?
This has to do with how we handle data privacy and how useful the data is for our research. Last year, nearly 2,000 people completed our annual survey. An open-ended question is then quickly answered by more than 500 people. Processing open-ended questions takes a lot of time and effort. Also, the way people interpret the answers can differ, making it difficult to compare the results with previous years. In addition, participants may sometimes share privacy-sensitive information in their answers, which poses a risk. Where appropriate, we provide space for people to formulate their own answers, but we try to limit the number of open-ended questions. However, this does not mean that we do not take into account the diversity of our group: we try to pay as much attention to this as possible when selecting the closed questions.
