Testing the Impact of Two Posters on Contraceptive Knowledge, Contraceptive Preferences, and Perceived Pregnancy Risk

Completed · Not applicable

Conditions studied: Contraception, Knowledge, Attitudes, Practice

In brief

This study tests two posters that teach people about contraception: one designed by the Centers for Disease Control (CDC), and one designed by the researchers. The investigators hypothesize that the new poster will have more increased (1) contraceptive knowledge, (2) willingness to use effective contraception, and (3) perceived pregnancy risk than the CDC poster. This study will expand useful knowledge because contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk have been shown to affect women's likelihood of using contraception. If the investigators learn how to increase these factors, the investigators could theoretically reduce women's risk of unplanned pregnancy. The investigators will test this hypothesis by recruiting N=1000 women to complete an online survey using Amazon Mechanical Turk. These women will complete a survey that will first measure their initial contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk. Then women will randomly be shown one of the two posters. Then, the investigators will measure their contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk again. The investigators will use statistical tests (a t-test) to find out whether there are significant changes in these three outcomes for either of the posters, and whether one poster does a better job of changing these outcomes than the other.
