The Method Information Index (MII) is calculated from contraceptive users' responses to questions regarding counseling content-whether they were informed about methods other than the one they received, told about method-specific side effects, and advised what to do if they experienced side effects. The MII is increasingly reported in national surveys and used to track program performance, but little is known about its properties. Using additional questions, we assessed the consistency between responses and the method received in a prospective, multicountry study. We employed two definitions of consistency: (1) presence of any concordant response, and (2) absence of discordant responses. Consistency was high when asking whether users were informed about other methods and what to do about side effects. Responses were least consistent when asking whether side effects were mentioned. Adjusting for inconsistency, scores were up to 50 percent and 30 percent lower in Pakistan and Uganda, respectively, compared to unadjusted MII scores. Additional questions facilitated better understanding of counseling quality.
方法信息指数（MII）是根据避孕药具使用者对咨询内容的回答计算得出的——他们是否被告知除了他们所接受的方法之外的其他方法，是否被告知特定方法的副作用，以及如果他们遇到副作用应该怎么做。MII 在国家调查中越来越多地被报告，并用于跟踪项目绩效，但对其性质知之甚少。使用其他问题，我们在一项前瞻性多国研究中评估了反应与所接受方法之间的一致性。我们采用了两种一致性定义：（1）存在任何一致的反应，（2）不存在不一致的反应。当询问用户是否被告知其他方法以及如何应对副作用时，一致性很高。当询问是否提到副作用时，反应的一致性最低。在调整了不一致性后，与未经调整的 MII 得分相比，巴基斯坦和乌干达的得分分别降低了高达 50%和 30%。额外的问题有助于更好地理解咨询质量。
