Original researchUnderstanding risk: a randomized controlled trial of communicating contraceptive effectiveness☆
Section snippets
Materials and methods
We recruited reproductive-age women (18–44 years) at five shopping malls (Matteson, IL; Pembroke Pines, FL; Phoenix, AZ; San Antonio, TX; and Springfield, VA) between August and September 2001. We set recruiting quotas to have the convenience sample reflect the race and education profile of the US population.4, 5 Participants completed self-administered questionnaires that collected demographic information, contraceptive use history, motivational factors for choosing contraceptive methods, and
Results
Our analysis is based on 433 participants (FDA table n = 147; WHO table n = 144; category table n = 142). We excluded six questionnaires from the analysis because the age information was missing and 22 questionnaires because of missing participant identifier information. The participants had a mean age of 26 with an average of 13 years of education (Table 1). The majority (63%) were white, and most (83%) had discussed birth control with a health care provider. A similar proportion (79%) said
Discussion
In our convenience sample, effectiveness was the most important reason for choosing a contraceptive method; this finding is consistent with that of other recent studies.9, 10, 11, 12, 13, 14 Before our intervention, only about half the participants could correctly state which one of two commonly used contraceptives was more effective. The table with general categories of effectiveness communicated relative contraceptive effectiveness better than the tables with numeric estimates of pregnancy

Prior work has shown that both written materials and graphical aids can provide effective contraceptive education [3, 4]. This work builds on existing contraceptive posters [24, 25] in being more comprehensible, relevant, and acceptable to women.
