New medical abortion regimens are being tested with increasing frequency. However women's preferences for certain attributes of the regimes are not being investigated to any great degree. Consideration of women's preferences in designing new regimens may help to optimize the medical abortion process. The proposed prospective survey research will attempt to determine women's preferences for individual aspects of medical abortion treatment and various regimens, and to determine what attributes of medical abortion treatment may be driving these preferences. The information collected in this study may be used in developing future treatment regimens or as the groundwork for future research into preferences, acceptability, and satisfaction with treatment.
