Figure 1 The National Survey of Family Growth (NSFG) construct of measurement of pregnancy intention modified to indicate how the new construct was created. Green text denotes the survey questions from the NSFG (2). Asterisks note where assumptions were relaxed for the new measure. Specifically, [1] women not using birth control because they wanted to become pregnant are classified as intended regardless of the timing of the pregnancy using the new measure (whereas the traditional NSFG measure asks additional questions regarding timing); [2] women not using birth control but who reported they did not mind becoming pregnant are now classified as intended (whereas the traditional NSFG measure does not incorporate information regarding the reasons for not using birth control in this case); and [3] women who stopped using birth control to become pregnant are now classified as intended regardless of timing (whereas the traditional NSFG measure asks additional questions regarding timing).
