This monograph is a guide for assessing linkages that can be used as needed in regional or national contexts. It covers a broad range of linkages issues such as policy, systems, and services. It is meant to assess HIV and sexual and reproductive health bi-directional linkages at the policy, system, and service-delivery levels. It is intended to identify gaps and thus contribute to the development of country-specific action plans to create and strengthen these linkages. It recommends specific steps for conducting the assessment and specific instruments to be used as interview schedules or guides.
