We compared participants\u2019 responses to three individual questions \u2013 Timing (\u201cHow do you feel about having a child now or sometime in the future?\u201d), Importance (\u201cHow important is it to you to avoid becoming pregnant now?\u201d), and Wantedness (\u201cDo you want to become pregnant in the next year?\u201d) \u2013 to responses to the 14-item Desire to Avoid Pregnancy (DAP) scale, a psychometrically valid measure of pregnancy preferences.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed data from the Surveys of Women, population-based longitudinal studies of reproductive-aged females in nine US states.

The lowest and highest categories of Timing, Importance, and Wantedness largely captured individuals with low and high DAP scores, respectively. However, the highest categories also included large proportions of individuals with a moderate preference to avoid pregnancy (Timing: 45% of those with mid-range DAP scores, Importance: 43%, Wantedness: 70%). Similarly, the non-polar categories of the individual fertility desire questions included individuals across wide ranges of DAP scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions for Practice<\/jats:title>\n                    <jats:p>Asking about wanting pregnancy can identify those most open to pregnancy but does not differentiate fertility preferences among individuals not explicitly desiring pregnancy, which is most people.
