Introductory questions should be easy and pleasant to answer, spark the respondents interest in participating and begin to open communication between the interviewer and the respondent. These principles are particularly important for surveys on violence against women, since they contain topics that can cause embarrassment, shame and fear and which respondents would often prefer to keep private. The sequence of questions is therefore critical in terms of preparing respondents for the questions to come and ensuring that respondents are oriented towards thinking about and disclosing their experiences.
