Research Published in Contraception Outlines a New Model for Measuring Acceptability of a Long-Acting Contraceptive Vaginal Ring
NEW YORK (16 December 2014) — The Population Council published new research in the November issue of the journal Contraception demonstrating that an investigational one-year contraceptive vaginal ring containing Nestorone® and ethinyl estradiol was found to be highly acceptable among women enrolled in a Phase 3 clinical trial. Because the perspectives of women are critical for defining acceptability, researchers developed a theoretical model based on women’s actual experiences with this contraceptive vaginal ring, and assessed their overall satisfaction and adherence to instructions for ring use. In this trial, researchers also measured continuation of ring use for up to one year.
“Understanding the factors that influence women’s satisfaction with and acceptability of a contraceptive method helps researchers and product developers design and test products that better meet their health and family planning needs,” said Ruth Merkatz, Director, Clinical Development, Center for Biomedical Research at the Population Council. “Our results add to the growing body of evidence documenting the acceptability of our investigational contraceptive vaginal ring. With the development of this model, we can continue studying women’s preferences for this and other vaginal rings to ensure that introductory and educational efforts are user-centric and responsive to women’s needs.”
