In recent years, there has been much reflection on the measures used to assess and monitor contraceptive programming outcomes. The meaning and measurement of intention-to-use (ITU) contraception, however, has had less attention and research despite its widespread inclusion in many major surveys. This paper takes a deeper look at the meaning and measurement of ITU around contraception. We conducted a scoping review guided by the following questions: What is the existing evidence regarding the measurement of ITU contraception? What definitions and measures are used? What do we know about the validity of these measures? We searched databases and found 112 papers to include in our review and combined this with a review of the survey instruments and behavioral theory. Our review found growing evidence around the construct of ITU in family planning programming and research. However there are inconsistencies in how ITU is defined and measured, and this tends not to be informed by advances in behavioral theory and research. Further work is needed to develop and test measures that capture the complexity of intention, examine how intention differently relates to longer-range goals compared to more immediate implementation, and demonstrate a positive relationship between ITU and contraceptive use.
