This study tests the hypothesis that women will be more likely to continue a contraceptive if their expectations about changes in bleeding and discomfort are accurate. The study examined the relationship between women's expectations and discontinuation rates for IUD and pill acceptors over a three-month interval. The results show that attitudes and expectations are as important as actual changes in accounting for contraceptive discontinuation among pill users; the results for IUD users are not as clear. It is recommended that family planning programs make it a priority to inform women about the changes in their bodies that can be caused by contraceptives in order to reduce high rates of discontinuation.
如果女性对出血和不适变化的期望准确，她们就更有可能继续使用某种避孕方法。该研究考察了女性的期望与宫内节育器（IUD）使用者和口服避孕药使用者在三个月期间的停用率之间的关系。结果显示，在解释口服避孕药使用者的避孕方法停用情况时，态度和期望与实际变化同样重要；宫内节育器使用者的结果则不那么明确。建议计划生育项目优先向女性告知避孕方法可能引起的身体变化，以降低高停用率。
