Questions about violence by any other previous intimate partner (before the current or most recent partner) should be asked only once in order to avoid placing an excessive burden on respondents who have had more than two partners. In addition to the content and structure of the questionnaire, consideration should also be given to the format of the questionnaire in order to improve the flow of questions. For example, in the case of paper questionnaires, it is known that the use of graphics, such as arrows, or coloured or bold text, aids in the accurate flow of questions, particularly where skip and filter questions are used.
