Abstract:
Our objective was to evaluate a media campaign designed to increase knowledge about emergency contraception. Random telephone surveys were conducted before and after the campaign to measure changes in knowledge about emergency contraception. Change in the volume of calls to the Emergency Contraception Hotline (1-888-NOT-2-LATE) was a secondary measure of impact. Significant increases occurred in the proportions of women who knew that something could be done after intercourse to prevent pregnancy, who knew the term emergency contraception, who knew of the 72-h time limit, and who had heard of the Hotline. In addition, the number of calls to the Hotline increased substantially. A public education media campaign resulted in significant increases in knowledge about emergency contraception. The first contraception advertisement ever shown on television did not provoke controversy.
